Dear readers,
The construction and real estate economy are in a state o change: energy eciency,
resource protection, residential and workplace health, value retention and risk mitigation
are now in ocus. General conditions and market interests are changing. Thereore, in the
uture buildings will be planned, built and operated dierently.
Against this background, the German Sustainability Building Council (DGNB) together withthe Federal Ministry o Transport, Building and Urban Aairs (BMVBS) developed a voluntary
certication system or sustainable buildings. It was developed by experts rom the complete
value chain o the construction and real estate sector and gives a clear orientation or this
uture-oriented economical sector. We are pleased to present the certication system in this
brochure.
The 2008 version o the German certication system is available or oce and administra-
tion buildings. The practical experience gained during the certications test phase as well
as a numerous comments rom the proessional world will be included in the development
o the 2009 version. Parallel to this, the fexible rating system is being developed step-by-step or other construction types. As previously, experts will be involved in the development
process. This decision process is pushed orward by the non-prot-organisation DGNB as
driving orce and moderator.
The DGNB considers itsel to be the central organization or exchange o knowledge, proes-
sional training, and or a raising public awareness or sustainable construction in Germany.
The ocus o the DGNB is the development o the certication system that is described in
detail at the ollowing pages.

German Sustainable Building Certicate
Sustainable building means to build intelligently: The ocus is on
a comprehensive quality concept that serves the building and real
estate sectors, as well as society in general. Sustainable properties
are benecial to the environment, conserve resources, comortable
and healthy or their users, and t optimally into their socio-cultural
surroundings.
In the same way, they stand or economic eciency and long-termvalue-retention. Sustainable properties are cost eective due to
their lower operation and maintenance costs. The manageable ad-
ditional planning and construction costs will usually amortize in a
ew years.
The German Sustainable Building Certicate was developed by the
German Sustainable Building Council (DGNB) together with the
Federal Ministry o Transport, Building, and Urban Aairs (BMVBS)
to be used as a tool or the planning and evaluation o buildings in
this comprehensive perspective on quality. As a clearly arranged andeasy to understand rating system, the German Sustainable Building
Certicate covers all relevant topics o sustainable construction, and
awards outstanding buildings in the categories bronze, silver, and
gold. Six subjects aect the evaluation: ecology, economy, social-
cultural and unctional topics, techniques, processes, and location.
The certicate is based on the concept o integral planning that de-
nes, at an early stage, the aims o sustainable construction. In this
way, sustainable buildings can be designed based on the current
state o technology, and they can communicate their quality withthis new certicate.
X The German certicate makes sustainability measurable andcomparable.
For planning and ealuation o buildings, tere is a ne
and clearl structured tool: Te German Sustainable Build-
ing Certifcate. As meritocratic rating sstem, it coers all
releant topics o sustainable construction. Outstanding
buildings are aarded in te categories bronze, siler, or
gold.

German Sustainable Building Certicate
Active Contribution to Sustainability
The certicate demonstrates, in a quantiable way, the positive e-
ects o a building on the environment and on society.
Cost- and Planning Certainty
The certication process provides, in the early planning stage, a high
degree o certainty that the perormance goals o a building can be
reached at the time o completion. For example, it helps reduce theenergy consumption and costs during operation.
Minimizes Risk
The certication process promotes integral planning during
construction. This leads to more transparency and well-dened
processes during planning and construction, opens up potentials or
optimization, and minimizes the risks during construction, opera-
tion, renovations, and removal.
Praxis-oriented Planning ToolThe certicate was developed by practitioners or practitioners. It
supports owners and designers in a goal-oriented way in develop-
ing sustainable buildings.
Focus on the Lie Cycle
The certicate is based on the lie cycle o a building, which is indis-
pensable or an evaluation o the sustainability.
Made in Germany
The certicate is optimally adapted to the German and Europeanbuilding environment. This includes building codes and norms, as well
as long-term market experience with energy ecient buildings etc.
Marketing Tool
The certicate serves as a communication tool or investors, owners,
and users it documents their commitment to sustainability. As a
sign o quality, it supports export, and it enhances the attractiveness
o the German real estate sector or investors.
Comprehensive Quality o a Property
The certicate enhances the chances or sale and rent. The certi-cation makes the high quality o a building tangible or owners
and users. Furthermore, it signals a perormance-enhancing work
environment as well as high user satisaction.
The Perormance is Key
The German certicate evaluates the buildings perormance and
not merely single measures. Owners and designers are given a large
leeway to achieve the targets.
More than Green BuildingThe certicate ar exceeds the ecologic aspects o green building
by also equally including the economic perormance, as well as
socio-cultural and unctional aspects o buildings.
Flexibility
The certicate system can fexibly be updated. It can easily be
adapted to technical, social, and international developments.

German Sustainable Building Certicate
I an owner wants to gain a certicate or a planned building, he
assigns an accredited DGNB auditor who, due to his training, is
amiliar with the requirements o the German Sustainable Building
Certicate. The auditor accompanies the owner on his/her way to
certication. The auditor advises the owner on all issues concern-
ing sustainable construction, ormulates the goals or the planned
building, and makes sure that the planning team implements the
agreed-upon sustainability criteria. The auditor summarizes thegoals o the project in a comprehensive object-specic specication
sheet.
Registration
To start the certication process or the planned building, the audi-
tor registers the object at the DGNB website www.dgnb.de.
Issuance o the Pre-Certifcation
Ater registration at the website, the auditor submits the object
specic specication sheet to the DGNB. It contains the dataregarding all criteria o the German Sustainable Building Certica-
tion and is a binding declaration o intent by the owner to realize
the planned perormance goals. The DGNB checks the documents
submitted by the auditor. I they comply with the requirements o
the certicate, the owner receives a pre-certicate or his building.
He therewith assumes responsibility or the implementation o the
discribed measurements. At the same time he is entitled to use this
pre-certicate in gold, silver, or bronze or the promotion o his
property.
ThE PAThwAy TO CERTIFICATION
Te pre-certifcation process allos oners to optimize
teir building during te planning pase and to market
it at an earl stage it erifable statements about its
sustainabilit.

Documentation
On this basis, the building design and construction can be started.
The consulting auditor is to establish an accompanying planning
and construction documentation in accordance with the specica-
tions o the DGNB documentation guidelines.
Inspection o Conormity
Ater completion o the building, the DGNB checks i the specica-tions o the pre-certicate have been realized. An assessor perorms
a conormity inspection based on the DGNB documentation guide-
lines, makes plausibility checks, and takes control-samples.
Award o the Certifcate
Finally, the DGNB reviews i the entire certication process was ex-
ecuted properly. I all requirements are ullled, the owner receives,
depending on the degree o compliance, the gold, silver, or bronze
certicate rom the DGNB and BMVBS, consisting o a certicate
and a plaque or his building. He may use these in his marketingactivities.
Auditors
Auditors accompany the owners during the certication process. To
be ocially recognized as DGNB auditors, they have to participate
in a multi-week training by the DGNB or by educational institu-
tions that have been accredited by the DGNB, such as Universities
or Chambers. The modularly structured curriculum consists o an
introduction to sustainable construction; it also conveys the relevant
contents or the implementation o the certication system.
X The Seal is awarded in gold, silver, or
bronze.

German Sustainable Building Certicate
METhODICAL PRINCIPLES OF ThE CERTIFICATION
SySTEM
The German Sustainable Building Certicate is a transparent
and comprehensible rating system that was developed based on
real-world circumstances. It denes the quality o buildings in a
comprehensive way, and enables auditors to conduct an evaluation
systematically and independently.
Supporting Sotware
User-riendly sotware supports the auditor with the documentationand evaluation process. The sotware visualizes the capabilities o
a building in a way that is concise and easy to understand. Already
during the planning process, it marks the infuencing parameters
were the building can be optimized with regard to sustainability.
Flexibility as Strength
The basis or the system was developed on the building type New
Construction o Oce and Administration buildings. On this basis,
urther systems or completely dierent building types will be
developed. As a second-generation certication system, the labelexcels with a high degree o fexibility. The basis o the evaluation,
which was developed with a wide consensus, is a list o topics and
the criteria or sustainable construction that are included within that
list. These criteria are weighted dierently, depending on the build-
ing type to be evaluated. Thus, each version o the system, hence
each building type, has its own evaluation matrix. An example is the
matrix or the evaluation o new oce and administration buildings
on page 11.
Te bencmarks or aarding te certifcate are orien-
tated on te current state-o-te-art and on an integral
planning statement tat includes te aims o sustainable
construction.
Clear Topics
During the evaluation, 6 topics are considered by the certicate:
Ecological Quality
Economical Quality
Socio-cultural and Functional Quality
Technical Quality
Quality o the Process
Quality o the Location
X The Certicate: For the evaluation o the buildings quality, ve
topics are considered. The quality o the location is presented
separately.

German Sustainable Building Certicate
Te interested parties are included during te deelop-
ment o eac ne ersion o te certifcate rom te er
beginning.
The topics are weighted dierently in the overall assessment o the
building, depending on their relevance. For example, or the certi-
cate New Construction Oce and Administration, Version 2008,
both the economical and the ecological quality have the same
weighting (22.5% each). The quality o the location is not included
in the nal grade but is presented separately.
Conclusive Individual CriteriaEach topic is divided into several criteria. For instance, the energy
consumption, acoustical quality, or land consumption are consid-
ered or the evaluation o a building. For each criterion, measur-
able target values are dened, and a maximum o 10 points can
be assigned. The measuring methods or each criterion are clearly
dened.
Detailed Weighting
At the same time, each criterion has a weighting actor: it can fow
threeold into the evaluation o its respective topic. This way, orinstance, the energy consumption o an oce building is o more
importance than the acoustical comort. The weighting actor can
also be zero the consideration o motorway bridges does not
require the criteria or indoor air quality.
Clear presentation o Results
Each criteria fows into the overall result in a clearly dierentiated
way. A sotware-supported computation displays the buildings
perormance: by reaching a dened degree o perormance, it is
assigned the bronze, silver, or gold award. Furthermore, grades are
given or the total perormance o the building as well as or the
individual topics.
Praxis-oriented Continuing Development o the
System
On this basis, the German Sustainable Building Certicate can be
adapted, in a practicable way, to the individual requirements odierent building types. Similarly, it can be adapted to regional
requirements or social developments, or example to the increasing
importance o individual criteria like indoor air quality or CO2-
emissions o a building. The strength o the system is also based on
the involvement, rom the beginning, o interested parties during
the development o new variations. A supplementary commenting
procedure ensures that the requirements o the construction and
real estate sector are systematically queried and included into the
system.

German Sustainable Building Certicate
The German Sustainable Building Certicate was initially developed
or new oce and administration buildings. In version 2008, which
emerged rom the pilot phase o the certication system, the sus-
tainability o oce and administration buildings is evaluated based
on 49 criteria.
The Topics
These criteria are distributed among the 6 topics o the system. Fiveo the topics fow into the nal grade: Ecological Quality, Economi-
cal Quality, Socio-cultural and Functional Quality, Technical Quality,
and Quality o the Process. The Quality o the Location is evaluated
separately. It is not included in the overall evaluation o the build-
ings quality, so that each building can be evaluated independent o
its location.
Evaluation Matrix
Each criterion can be assigned a maximum o 10 points, depending
on the documented or calculated quality. All criteria are weightedwith a actor rom 0 to 3, because individual criteria are treated
as either more or less relevant. The evaluation matrix on page 11
shows the structure o the system. The degree o compliance with
the requirements o the certication is calculated in accordance
with the evaluation matrix.

ECOLOGICAL QUALITy 12 CRITERIA
Criterion 01: Global Warming Potential (GWP)
J Goal
Reduction o the Global Warming Potential. The Global Warming
Potential is the potential contribution o a substance to warm the
near-surace air or the so called greenhouse eect. The contribu-
tion o the substance is indicated as GWP-value in relation to the
greenhouse potential o carbon dioxide (CO2). For the certicationthe GWP 100 value, which is the contribution o a substance to the
greenhouse eect over a period o 100 years, is used.
J MethodologyEvaluation o the greenhouse potential o the construction,
operation and disposal o a structure over a period o 50 years
(kg CO2-Equiv./mNFA*a). The input quantities can be gained rom
the operational phase o the energetic proo according to the Ger-
man regulation or energy saving in buildings and building systems
2007 (EnEV 2007 = in German: Energieeinsparverordnung 2007).For the identication o the ecological impacts o the buildings
construction, including its systems engineering, an eco-accounting
o the used materials and/or building parts according to DIN EN
ISO 14040 and 14044 is necessary. The required datasets or this
are provided via the inormation portal or sustainable building. For
the evaluation o the construction, including the systems engineer-
ing, reerence values are dened on the basis o an average oce
building. The evaluation o the Global Warming Potential criterion
is based on an average annual value o the realized building, which
is compared to the annual reerence value.
J Data BasisThe data identication (eco-balance as well as calculations o EnEV)
is largely the same or the criteria 01 to 05 and 10 to 11. By enter-
ing the building data into the appropriate sotware, the lie-cycle
costs can be calculated simultaneously.

Nutzungsdauern von Bauteilen
Criterion 02: Ozone Depletion Potential (ODP)
J GoalReduction o pollutant emissions that contribute to the destruction
o the ozone layer. Ozone is able to absorb short-wave UV-rays
and emit longer wavelength radiation omnidirectionally. The ozone
layer shields the earth rom a large part o the UV-radiation,
prevents excessive warming o the earths surace, and contributes
to protecting us rom UV-A and UV-B radiation. The accumulationo R
11-equivalent in the atmosphere contributes to the destruction
o the ozone-layer. Consequences are e.g. tumour generation in
humans and animals, as well as disruption o photosynthesis.
J MethodologyThe input quantities or the operating phase can be taken rom
the energetic documentation according to EnEV 2007. For the
determination the ecologic impacts o the buildings structure,
including the systems engineering, an eco-accounting o the used
materials and building parts according to DIN EN ISO 14040 and14044 is necessary. The required datasets or this are provided via
the inormation portal or sustainable building. For the evaluation

Criterion 03: Photochemical Ozone Creation
Potential, POCP
J GoalReduction o photochemical ozone creation potential the mass-based equivalent o destructive trace gases (e.g., nitric oxide and
hydrocarbons). These, in combination with UV-radiation, contribute
to the ormation o near-surace ozone. The human- and eco-toxic
contamination o the near-surace air is called summer smog. It
adversely aects the respiratory system and damages plants and
animals.
J MethodologyThe lower the photochemical ozone creation potential (summer
smog) is, the better is the evaluation (in kg C2H4-Equiv./mNFA*a).The input quantity or the operating phase can be taken rom the
energetic proo according to EnEV 2007. For the classiying the
ecologic impacts o the buildings structure, including its systems
engineering, an eco-accounting o the used materials and/or o the
building parts according to DIN EN ISO 14040 and 14044 is neces-
sary. The required datasets or this are provided via the inormation

Criterion 04: Acidication Potentialpotential
J GoalReduction o Acidication Potential. Acidication means rising o the
concentration o H-ions in the air, water and soil. Sulphur and ni-
trogen compounds rom anthropogenic emissions react in the air to
orm sulphuric and/or nitric acid that alls to the earth as acid rain
and negatively impacts water bodies, creatures, and buildings. The
sum o the individual acidication impacts leads to orest dieback
and sh mortality. Acidic precipitations corrode historical buildings(sandstone). The evaluation criterion or this environmental impact is
the acidication potential as is indicated by SO2
equivalents.

Criterion 05: EutrophicationPotential (EP)
J Goal
Reduction o Eutrophication. Eutrophication describes the transi-
tion o water bodies and soil rom a nutrient-poor to a nutrient-rich
(a.k.a..eutrophic) state. This state is mainly caused by supplying
phosphor- and nitrogen compounds. These compounds can getinto the environment via abrication o building materials and via
washing-o o combustion-emissions. The change in available nutri-
ents e.g., increases the ormation o algae in water bodies , which
can lead to higher sh mortality, among other things.
J MethodologyThe input quantity or the operating phase can be taken rom the
energetic proo according to EnEV 2007. For the classiying the
ecologic impacts o the buildings structure, including its systems
engineering, an eco-accounting o the used materials and/or othe building parts according to DIN EN ISO 14040 and 14044
is necessary. The required datasets or this are provided via the
inormation portal or sustainable building. For the evaluation o
the construction, including the systems engineering, reerence
values are dened on the basis o an average oce building (type-
representative). The nal evaluation o the Eutrocation Potential
criterion is based on an average annual value o the realized build-
ing (structure and use), which is compared to the annual reerence
value. The lower the eutrophication potential is, the better is the
evaluation (in kg PO4-Equiv./mNFA*a).

Criterion 06: Risks or the Local Environment
J GoalThe risks or the local environment are minimized through a pur-
poseul choice o building materials that come in contact with the
surrounding air, soil, and surace- and/or groundwater during the
operation o the building.
J MethodologyMaterials and substance types that can cause environmental risks
are queried individually and on a per-product basis. Substance types
that are considered are halogens, heavy metals, organic solvents,and substances and products that all under the biocide- and
REACH guidelines. There are 4 dened action-levels that build on
each other. The requirements o a higher action-level include the
successul implementation o all requirements o the level below
it. Each action-level contains a list o materials and products to
be avoided. The more action-levels that can be ullled, the lower
the risks or the local environment are. Proo or the successul
implementation includes: declarations or the required materials
and products, submission o material and product lists, and a test

Criterion 10: Non-Renewable Primary Energy De-
mands (PEne
)
J GoalThe use o non-renewable energy resources shall be reduced. With
the identication o the non-renewable primary energy demands,
the energy-eciency o the construction and use, as well as the
energy demands o the upstream chain is evaluated. The energydemands o the users equipment are not evaluated. Primary energy
is the energy that is available rom naturally existing energy sources.
Included are non-renewable energies such as black coal, brown
coal, petroleum, natural gas, and uranium.
J Methodology
The demands o non-renewable primary energy is calculated
over the lie-cycle o construction, reconditioning, operation, and
deconstruction/disposal o a building (in kWh/mNFA*a). The input
quantities or the operating phase can be taken rom the energeticproo according to EnEV 2007. For the classiying the ecologic
impacts o the buildings structure, including its systems engineer-
ing, an eco-accounting o the used materials and/or o the building

Criterion 09: Microclimate
J GoalThe choice o appropriate products and solutions shall reduce the
negative impact on the micro-climate o roos and aades, which
can contribute to heat islands.
Cities are signicantly warmer than rural areas due to the intense
warming-up during the daytime and the limited cooling-down atnight. This heat island eect can be compensated by creating
unsealed areas, greening, or the use o materials with low solar
absorption.
J MethodologyDocumentation o the roo- and aade materials with the aid o the
reerence table Albedo Values (Albedowerte).
Action Level 1: Documentation o character, colour, surace texture,
as well as the appropriately determined refection values (Albedo),absorbency, emissivity, and transmissivity o the roo and soil mate-
rials. Unsealed and planted areas are also documented, according
to their size and nature, on technical drawings. Further, inormation
concerning the surroundings o the building, such as the mass o
surrounding buildings, street-widths, and heights o the surrounding
buildings, as well as the orientation o the building is supplied. This
can be documented with photos and property- and elevation plans.

Criterion 11: Total Primary Energy Demands and
Percentage o Renewable Primary Energy
J GoalThe total demand or primary energy shall be minimized and the
percentage o renewable energy shall be maximized during the lie
cycle o a property. Among the non-renewable primary energies
are black coal, brown coal, petroleum, natural gas and uranium;and among the renewable energies are biomass, solar radiation,
geothermal energy, hydropower, and wind energy. The total value o
primary energy demands are evaluated, as well as the percentage
o renewable energy demands, as compared to the total primary
energy demands.
J MethodologyThe percentage o renewable energy as compared to the total
primary energy demands or the construction and use is evaluated
over a period o 50 years. The input quantities or the operatingphase are taken rom the energetic proo according to EnEV 2007.
Here, diering rom EnEV 2007, the standard is a coverage propor-
tion o 15 % o the heat-demand by solar heat. For the classiying
the ecologic impacts o the buildings structure, including its systems
engineering, an eco-accounting o the used materials and/or o the
building parts according to DIN EN ISO 14040 and 14044 is neces-
sary. For the evaluation o the construction, including the systems
engineering, reerence values are dened on the basis o an aver-
age oce building. The evaluation o the criterion Percentage o
Renewable Primary Energy is made by comparing the percentageo renewable energies regarding the total primary energy demands
o the realized building with the reerence building.

Criterion 15: Surace Area Usage
J GoalThe constant increase in trac and settlement areas shall be
reduced. Preerably, areas shall be used that are already assigned as
trac or settlement areas or that are allocated or the recovery o
contaminated locations.
J MethodologyIt is evaluated, in which degree and in which sense the type o area
consumption is changed by the construction project. Area is not
consumed, but a usage-change o the area takes place.
1. The previous use o the area can be determined rom the certi-
cates o title or extracts rom the land survey register.
2. The previous contamination o the property by contaminated
sites, munitions, etc. can be determined based on available
survey reports.3. The realization o compensation measures can be identied
based on available documents.
4. Based on the planning documents, it is checked i a greened roo
is planned, and can be approved as a compensation measure.
5. The type, extent, and direction o change o the actual use o the
area are recorded and evaluated (change rom nearly natural
to cultivated = negative; change rom contaminated area to
cultivated area = positive).
Criterion 14: Potable Water Consumption and Sew-
age Generation
J GoalPotable water consumption and sewage generation shall be
reduced. Despite the ample supply o water, there is a deciency
o high-quality potable water. Only ater elaborate ltration, where
naturally occurring iron and manganese, pesticides and nitratesrom agriculture, and other harmul substances are removed, can
water be used as potable water. The treatment o sewage in central
sewage treatment plants causes high expenditures, transport in
canalization, and the need or purication. The higher concentrated
the sewage is, the more eective is the purication. Inltration or
usage o storm water is preerable to the mere draining into the
sewage system. Inltration contributes to the stabilization o the
groundwater table, and evaporation contributes to the improvement
o the micro-climate. Storm water can replace potable water or
e.g., fushing toilets.
J MethodologyBy adding the ascertained potable water consumption and the
sewage emergence, the specic water-use value (Wasserge-
brauchskennwert) is generated. This represents a simple value or
the evaluation o the handling o water in the building. The basis or
the evaluation is established with the aid o dened assumptions
concerning consumer behaviour and specic values.

Criterion 17: Value Stability
J GoalA globalized and international market demands high eciency,
fexibility, and adaptability. This is also refected in the utilization
o buildings. A building designed or sustainability can be easily
adapted to changing requirements. Change in the usage can result
rom tenant or user changes, and also rom reorganizations by thetenant. A high level o adaptability o buildings under the criterion
o sustainability is present, i the alteration can be realized with a
small amount o resources.
J Methodology
Area eciency and adaptability o a structure are evaluated with a
checklist. The criterion is based on the utilization phase o the struc-
ture. The largest opportunities to infuence the direction are during
the project development and planning phases. The better a building
can be altered and the less elaborate an alteration is, the better theability to alterate is rated. Considerable resources savings can be
achieved by considering the optimization o area utilization in an
early planning phase. The ollowing indicators are checked:
1. Proo o inspection o the area eciency
2. Modularity o the building
3. Spacial structure o the building
4. Electrical- and media provision
5. Heating, climate control (HVAC), water supply, and sewage
disposal
Criterion 16: Building-related Lie Cycle Costs (LCC)
J GoalSome o the goals o economic sustainability are the minimiza-
tion o a buildings lie cycle costs and the relative cost reduction
o alteration and preservation investments in comparison to new
constructions. In the past, the conventional planning and con-
struction process was ocused mainly on the minimization o themanuacturing costs o a building. The ollow-up costs receive only
little consideration. However, current cost savings shall not be made
at the expense o the uture users and owners. Since the ollow-up
costs thereore need to receive more consideration, the expected
ollow-up costs have to be evaluated. For this, only the building-
specic costs are included.
J MethodologyThe lower the lie cycle costs according to the cash-value method
(Barwertmethode) (in /mNFA), the better is the evaluation. Liecycle costs o a building are all costs that arise during the entire
useul lie o a building. The costs beginning with the project deve-
lopment up to construction and handover are dened as production
costs. The costs rom commissioning up to disposal are dened
as ollow-up costs. The lie cycle costs are divided into three cost
categories: production costs, ollow-up costs, and deconstruction
and disposal costs. The largest opportunities to make decisions and
improvements are during the project development and planning
phases.

Criterion 27: Area Eciency
J GoalAreas should be handled as economical as possible. Area eciency
is an index or the utilization o foor space inside buildings. A report
by the German Society o Real Estate Funds (Deutsche Gesellschat
r Immobilienonds) states that 2/3 o the project developers
consider the actor area eciency as a superior planning item. Withreerence to the augmentation o area eciency the ollowing goals
or improvement can be presented:
1. Optimization regarding costs
Decrease o construction and operational costs, avoidance o
restricted use areas.
2. Environmental Optimization
Reduction o the property environmental impacts during operation,
by reducing the technical equipment required or heating, ventila-tion, and cooling. With increased area eciency the sealing o
natural soil can be reduced.
3. Contribution to optimization in the social sector
Positive interaction in the working environment with well propor-
tioned areas and a clearly arranged design.
J MethodologyThe specic value area eciency corresponds to the proportion
between usable foor space to gross foor area (in m/m).
Criterion 26: Barrier-ree Accessibility
J GoalBuildings shall be constructed barrier-ree. Barrier-ree accessibility
augments value and attractiveness or all population groups and
concerns or all people with motor and sensory restrictions. The
percentage o these people will increase due to the demographic
shit. This has to be mastered with orward-looking and sustainabledevelopment.
J MethodologyThe evaluation is carried out qualitatively to the degree o barrier
reedom. The allocation o credits is orientated on the possibility o
the equal utilization o the building by all people. The basic accessi-
bility has to be assured. Without this basic accessibility no certi-
cation or a new construction can be assigned. The more parts o
the building that are adapted to the needs o disabled persons the
better the whole building is rated. Also the external eature areashave an important benet value and are thereore also included in
the evaluation. The evaluation is orientated on the actual standardi-
zation.

2. Spatial structure3. Supply o electricity and other media
4. Heating, supply and disposal o water
Criterion 29: Accessibility
J GoalAcceptance and integration o a building inside a district, city and
region shall be enhanced by increased accessibility. Public acces-
sibility enhances social communication. A diversity o use generates
vitalization o the public space and augments the sense o security
o the users. At the same time it contributes to the economic sus-tainability o the building.
J MethodologyWith a checklist the ollowing topics are evaluated:
1. Basic accessibility o a building
2. Opening o the external areas or public
3. Opening o buildings acilities to public such as library or

and energy ecient mobility. Missing building-specic inrastructure
or bicycles in praxis oten leads to wild parking in the publicspace. Undervalued bicycle comort oten leads to breakdown o the
bicycle inrastructure and cannot be compensated.
J Methodology
The bicycle comort is evaluated in a checklist with the ollowing
topics:
Art o arrangement o the bicycle storing positions and required
space
Quorum o storing positions per m NFA Are the storing positions located in ront o the main entrance?
Are the storing positions located in a proper distance to the
main entrance?
Do the oered storing positions meet the unction o the build-
ing
Are showers and changing rooms with drying acilities or the
employees bicycle clothes present?
J GoalPlanning competitions shall take place to attain the best solution
or the architectonical and constructive tasks. With this, the architec-
tural diversity in Germany is assured. An expert jury can judge best
architectonical solutions and integration into the urban context.Planning competitions in Germany are conducted under standard
regulations. They allow clients to nd the appropriate contractor
within a clearly structured and transparent procedure. Competitions
orward creativeness, innovative solutions and are ecient methods
to optimize quality and protability. With the reward o planning
competitions, alternative solutions are developed that meet the
demands concerning design, protability, unctionality, energy
conservation, and environment protection.
J MethodologyExtent and quality o the conducted competitions have to be identi-
ed:
1. Has a successul competition been conducted according to
GRW95, RPW2008 or a similar method including the evaluation
o the competition entries by a jury?
2. Which competition method was chosen; and does it include the
least number o restrictions?
3. Does the constructed building match in extent and quality the
essence o the award-winning competition entry?

J Data BasisThe necessary parameters or the calculation can be extracted rom
the state building code, the re protection concept, and the an-
nouncement documents.
Criterion 34: Noise Protection
J GoalNoise protection shall be improved. Minimum requirements o struc-
tural noise protection are dened in DIN 4109. This only addresses
the unacceptable but not automatically all possible noise pollutants.
Additional requirements to noise protection in oce buildings are:
avoiding loss o concentration, protection o privacy and condenti-
ality, and consideration or people with limited hearing.
J MethodologyMeasures that exceed the minimum noise protection requirementslead to a better score. A pointless exceeding o the standards shall
be avoided. The quality o noise protection o building parts is deter-
mined rom the certicate o noise protection or the quality o the
specied building parts. It is evaluated i the building parts comply
with the regulations o DIN 4109 supplement 2 and where the
regulations are exceeded:
1. Airborne noise protection against surrounding noise
2. Airborne noise protection against other workplaces and against
the own workplace3. Impact-sound protection against other workplaces and against
the own workplace
4. Structure-borne sound protection against other workplaces and
against the own workplace
Criterion 33: Fire Protection
J GoalThe quality o re protection measures shall be increased. The main
cause o death involving re in buildings is toxic smoke. Measures
that exceed the re protection regulations can be rated positively.
However, re protection measures that exceed the legal regulations
should also consider the total economic impact as well as additionalemissions caused by the addition amounts o raw materials and
supplies.
J MethodologyA checklist evaluates the ollowing issues, as long as they exceed
the minimum requirements set by the building authorities:
1. Is the building equipped with an area-wide re alarm and electro
acoustic alarm system, so that a prompt response in a hazardous
situation is possible?2. Is a sprinkler system present that delays the res expansion, and
that enables the re department to carry out eective re ght-
ing at an early stage?
3. Can the ventilation system be used or smoke extraction in
case o re, and does the system prevent a re-circulation o
the (smoke-lled) air during the smoke extraction? Do air duct
systems have re dampers to prevent the distribution o smoke
during a re?
4. Is the spreading o smoke and re avoided beyond the required
amount by reducing the sizes o the red compartments?5. Is spreading o smoke and re avoided through structural meas-
ures beyond the required amount?

Criterion 40: Ease o Cleaning and Maintenance o
the Structure
J GoalWith targeted cleaning and maintenance, the used materials can be
operated or the maximum useul lietime. The ease o cleaning and
maintenance o the structure has a high impact on the costs and
the environment o a building during the operating phase. Areasthat can be cleaned easily require lower expenditures on cleansers
and cause lower cleaning costs.
J MethodologyFor the evaluation, the building is divided into the ollowing three
categories o building parts:
Bearing structure
External non-bearing structure, incl. windows and doors
Interior non-bearing structure
The technical implementation o each section is evaluated. Bymeans o the technical parameters, it shall be identied whether a
structure, based on its technical planning and construction, enables
ecient cleaning and maintenance. The dierent sections o the
construction are considered separately. Criteria or maintenance and
or cleaning are queried.
J Data BasisThe Guidelines or Sustainable Building (Leitaden Nachhaltiges
Bauen) provides ranges or the average useul lietime o build-
ing parts and layers o building parts according to Lie Cycle Costs(LCC) and Lie Cicle Analysis (LCA). The cleaning and maintenance
parameters have a signicant infuence on the useul lietime o
building parts and layers o building parts.
Criterion 35: Energetic and Moisture-Proong
Quality o the Buildings Shell
J GoalThe energy demand or the space conditioning shall be minimized,
high thermal comort shall be assured, and structural damages shall
be avoided. The quality o heat insulation and moisture-proong o
the buildings shell shall be optimized.
J Methodology
Basis o the requirements are the specications o EnEV 2007, DIN
4108, and DIN EN 12207. A higher quality increases the score.
Individual requirements or the parts o the buildings shell are
described. Reerence values are determined with the ollowing
method:
The buildings shell is evaluated with a checklist o the ollowing
criteria:
1. Average heat transmission coecient (qualitative)
2. Consideration or thermal bridges (qualitative)
3. Permeability o joints (qualitative)
4. Formation o condensate (qualitative)

J MethodologyThe building is evaluated with a checklist:
1. Building services
2. Non-structural (de)construction parts
3. Non-bearing carcass structure
4. Bearing carcass structure
For each group, the ollowing topics are considered:
Eort o dismantling divided into 5 dismantling stages
Eort o separation divided into 5 stages
Are there hazardous building materials or materials that need to
be declared that require special disposal?
Can these materials be easily separated, and is a separated
disposal possible?
Can a veriable recycling-/disposal concept be attached to the
request or certication? What is the potential urther path o the vast majority (mass) o
the construction components?
Criterion 42: Ease o Deconstruction, Recycling,
and Dismantling
J GoalGoal o increasing the ease o deconstruction, recycling, and
dismantling is the avoidance o waste, in particular by reducing its
amount and hazard. 50% o the waste in Germany can be assigned
to the building sector. The amount o accumulated waste is to bereduced, and is to be led into recycling system. Due to the compara-
tively long expected useul lietime, many o the materials that are
used today will not accumulate as deconstruction material or poten-
tial waste until 50 or 100 years ater construction. These materials
can serve as important resources or uture construction materials.
The ability to recapture homogenous deconstruction materials and
extract high-grade recycling materials is very important or the
evaluation o ease o deconstruction and ease o recycling.

are essential preconditions or realizing sustainable buildings. This
necessitates enhanced coordination between all participants. Inte-
gral planning encompasses the entire liecycle o a building; it starts
with the project design and ends with the buildings demolition.
An interdisciplinary design team, together with the owner, develops
an integral concept with a comprehensive strategy that is oriented
toward sustainability, in order to, via high-quality planning, reduce
energy consumption and environmental pollution, and at the sametime to improve the level o comort and be economical.
J Methodology1. An interdisciplinary design team covers the most important
disciplines o the project. This generally includes at least the
categories design, structural, technical building equipment, and
building physics. For contest and the work phases 1 to 5 (HOAI
15), the involvement o interdisciplinary design teams has to be
veried.
2. Integral planning process: All targeted certication criteria are tobe integrated into the planning. Their successul integration is to
be presented through a short description o the results or each
work-phase starting rom the concept design through the nal
design and site supervision (HOAI 15, WPH 2 to 5 and WPH 8).
3. Did participation, consultative involvement, and a co-determi-
nation o the users take place? The inclusion o the uture users
into the design normally increases their acceptance and satisac-
tion.
4. Was the public involved, were they inormed and consulted, and
could they participate? An increased public participation canbe an important contribution to higher acceptance o decisions,
balanced solution, better quality decisions, ewer conficts, and
more identication o the population with its living and social
environment.
Criterion 43: Quality o the Projects Preparation
J GoalThe tasks that should be achieved prior o work phase 1 o the Ger-
man ee structure or architects and engineers (HOAI = in german:
Honorarordnung r Architekten und Ingenieure), should optimally
prepare the project. To be considered are: planning o the needs,
discussion to identiy the objective, agreement on an objective,preparation o the architectural contest, and exerting infuence
over the energy input caused by the user and the usage. Especially
the agreed upon objective is an essential element o a high quality
project preparation.
J MethodologyThe ollowing aspects will be veried and evaluated using a checklist:
1. Does quality-oriented planning or the needs exist?
2. Was a discussion to identiy the objective conducted?3. Was an agreement on an objective reached?
4. Was an architectural or design contest with special consideration
or Sustainable Building prepared?
5. Was user behaviour and user equipment considered during the
simulation, and was goal-oriented infuence over the energy
needs o the user and the usage exerted during planning and
consultations?
Criterion 44: Integral Planning

Criterion 46: Evidence o Sustainability during Bid
Invitation and Awarding
J Goal
The oundation or a high-quality construction execution is laid
during the bid invitation and awarding phases. During these phases,
specic, manageable, and veriable requirements or products and
technologies or reaching the sustainability targets shall be ormu-lated. A contribution to the unctionality and quality o the building
structure with simultaneous minimization o risks and impacts on
the environmental and health shall be achieved.
The integration o sustainability aspects into the bid invitations
serves to raise the ecological and social quality o the building
by preventing the decisions on product quality rom being made
exclusively on economical viewpoints.
The integration o the sustainability aspects during the selection
o companies serves to raise the economical and social quality othe building.
J MethodologyThe ollowing aspects will be veried and evaluated using a check-
list:
1. Integration o sustainability aspects into the bid invitation: The
inclusion o sustainability aspects in the bid invitation will be
veried. For this, relevant experts o the announcement are to be
presented.2. Integration o sustainability aspects during the selection o
companies: It will be veried i the selection o the construction
rms was based on sustainability aspects, and which aspects o
sustainability were incorporated into the selection during award.
Criterion 45: Optimization and Complexity o the
Approach to Planning
J GoalThe necessary complexity o the approach to a design task shall
be secured by a minimum number and quality o concepts that are
to be generated. At the same time, the comparison o alternatives
shall be perormed with a heightened emphasis on economicaland ecological aspects as well as encouraging an external quality
assurance during planning. Normally, those aspects are dealt with
that must be worked on and veried during planning anyhow. By
developing a comprehensive concept, the quality and traceability
will be increased. The common and partially required German saety
regulations are o a high standard, which should, especially in the
international context, be emphasized.
J MethodologyThe availability, extent, and quality o the ollowing concepts anddocumentation will be veried and evaluated; as also, the type and
scope o the implemented alternative comparisons will be judged:
1. Health and Saety Plan
2. Energy Concept
3. Water Concept
4. Waste Concept
5. Measurement Concept
6. Concept or supporting the abilities o alteration, revitalization,
and recycling7. Concept or assurance or ease o cleaning and maintenance
8. Verication o the design documentation by independent third
party beyond the legal requirements
9. Comparison o alternatives

1. Building documentation / building certication
2. Instructions or maintenance, inspections, operation, and care
3. Update o the drawings and calculations with the realized build-
ing4. Users guide
Criterion 48: Construction Site / Construction
Process
J GoalThe eects on the environment are to be minimized while simulta-
neously protecting the health o all participants. The evaluation o
the construction site and construction process includes ollowingcriteria:
1. The low-waste construction site: When buildings are constructed,
altered, or demolished, rubbish, excavated soil, letover materi-
als, packing materials, old wood, etc. accumulate. This waste is
to be avoided or salvaged. Waste that is neither avoidable nor
salvageable should be ecologically disposed.
2. Low-noise construction site: Permanent exposure to noise can
lead to overstimulation o the nervous-system and, thereby, to
health problems. In densely built areas, construction noise, atertrac noise, is the most signicant noise source. Thereore, it is
to be demonstrated that the construction noise does not exceed
the general noise level, or that adequate measures are used to
reduce it.
Criterion 47: Establishing Preconditions or an Op-
timized Use and Operation
J Goal1. The issue o a building certicate and property documentation
should provide more market transparency and a unied basis o
inormation. The property documentation, which accompanies
the building during its entire lie time cycle, supports the proc-esses o controlling and continuous improvements during the
utilisation phase.
2. Creating and documenting comprehensive instructions or main-
tenance, inspection, operation, and care can make an important
contribution to an ecient operation o the building, and thus
reduce its lie-cycle costs. The documentation should ensure that
all preconditions are met to guarantee high-quality unctionality
and a long lie expectancy.
3. Detailed design documentation and calculations o the building
that match the actual building conditions are an important basisor the management and later maintenance, reurbishment, or
renovation works o the building. These are vital or the long-
term smooth and lasting operation o the building.
4. Creating a users guide provides specic and relevant inorma-
tion to a range o users in the areas work-, utilization, and
responsibility. The purpose o a users guide is, among other
things, to explain the interrelationships o the various technical
building systems, as well as explain the special characteristics o
individual building parts and components.

Criterion 49: Quality o the Executing Contractors/
Pre-Qualication
J GoalCompetence and quality o the executing contractors shall be
described and valued. An appropriate instrument or the verication
o these qualities is the pre-qualication o the perorming contrac-
tors. In practice, additional in-house quality controls and evaluationsare applied. By being registered in the pre-qualication list, the
contractors document their reliability, technical qualication, and
capability with a kind o quality certicate to the awarding author-
ity. Pre-qualication (PQ-Procedure) is a preceding, assignment-
independent verication o suitability. The pre-qualication covers
the complete perormance chain up to the implementation o the
subcontractors. Companies can avoid the disqualication o their
proposals or ormal reasons due to incomplete or outdated suit-
ability verication, and they optimize their chances o participating
in limited announcements and negotiations. By awarding the con-tract to a PQ-certied contractor, the contracting agency can reduce
the potential risks, like insolvency o a participating contractor.
J Methodology
