1975

ASHRAE accepts the challenge to develop information on energy efficient building design – ASHRAE 90-75

June 2002 – Honolulu ASHRAE Annual Meeting

Recognized that standards language and format limit the ability to provide education and guidance during critical design phase.

Challenge was given to ASHRAE to develop a suite of documents to achieve 30, 50 and 75% energy savings over Standard 90.1

June 2003 – Kansas City ASHRAE Annual Meeting

Small group met – ExCom, TechC, TCs, other organizations

Technology Council – Established Special Project 102 Charged with developing guidance on

achieving 30% energy savings in buildings

Assigned responsibility to Cognizant Committee

Cognizant Committee Steering Committee

Serve oversight and management function Responsible for setting direction and final

approval of work of SP ASHRAE senior leadership TC 2.8 – Building Environmental Impact and

Sustainability TC 7.6 – Systems Energy Utillization SSPC 90.1 IESNA AIA NBI DOE

Aug 2003 – Cognizant Committee met in Washington, DC

Develop Partnership between organizations Identify purpose and scope Determine major participants in writing group

Small, agile, skilled, interdisciplinary group Skill sets of individuals and representation

needed on SP-102 writing committee Established SP Committee to implement the

development and writing of document - Members from all the organizations

Identify timeline of 1st project – goal of 1 year Develop white paper charge to SP-102 which

discussed purpose, scope (included and not included), philosophy and intent of document

AEDG Purpose / Objectives:

Achieve 30% energy savings over 90.1

Target audience: contractors, owners, design / build

teams designers, operators

Provide “how-to” design assistance to contractors and designers

Scope of Document: Not going to be able to “eat the entire

elephant in one bite” – Scope must be managable

Building type and size– office building < 20,000 ft2 - most prevalent building type

Base Criteria: 90.1-1999 Savings location specific not national aggregate 30% was a hard target – plug loads not included Focus on air-side distribution Need an easy-to-use, simple, and small

document Not a code or code-intended document

Key Elements of Document and Development Process:

A WAY – NOT THE ONLY WAY to achieve target Can’t be all things to all people and can’t

cover all possibilities Not a standard or a code intended document Is intended to serve as initiator of additional

ideas for designers Energy is independent variable & cost-

effectiveness (e.g. payback) is dependent variable

Quality assurance is integral part User friendly – Remember the audience Serves as a teaching tool Systems integration is critical

Key Elements of Document and Development Process: (cont)

Provide both specific information and design concept intent information

Provide “how-to-do” information Use products currently on the market & at

least two manufacturers Plug loads – not included in savings credit Communication between CC and SP is

critical Questions of direction resolved quickly CC Chair participated in SP meetings SP Chair participated in CC meetings

Key Elements of Document and Development Process: (cont)

Document peer reviewed Three levels of Review – dates established

and published well in advance 1 - Conceptual 2 - Technical Overview 3 - Final for errors

Review handled by each organization AIA & IES – committee ASHRAE – 90.1, TC 2.8, TC 7.6, anyone requesting

Review by SP group and also CC Develop process for getting other

documents produced

Volunteer effort 11 person steering group 13 person writing team (SP-102) 5,000+ person-hours to develop

Where do we go from here? Topic of Current Discussions of CC 30% AEDG next building types

Retail/MercantileSubcategories A, B, C, …

Highway lodging Warehouses Healthcare facilities Educational facilities Larger office buildings

Where do we go from here? (cont)

Goal to produce two a year – staggered every 6 months

Start Approve Publish Retail A – spring ’05 spring ’06 Jun ’06 Lodging – fall ’05 fall ’06 Dec ’07 Warehouse – spring ’06 spring ‘07 Jun ’07

Additional Document Savings Levels – 50% 75%

A much more difficult problem Coordinated research is needed Need strategic plan to develop a

coordinated approach of research and development

Lessons Learned:

Commitment and enthusiasm are tremendous for this type project

5000+ volunteer man-hours in development Short-term, well-defined commitment is easier to

obtain Some expenses must be paid to get people needed Less “re-plowing ground” with compressed

timeframe “Speed of business” can be achieved – if schedule

is known and people can plan according Interdisciplinary team is critical – there is

tremendous power in combining efforts

Lessons Learned: (cont)

Organizations operate differently – Different professions need different

types/styles of documents Multistage reviews are very beneficial

Concept, technical, errors Users focus group – need to write pub

for users – not authors Input from the users early is

important

Lessons Learned: (cont)

There is tremendous enthusiasm and interest in these type of documents

This will be beneficial to all the organizations’ images

We can achieve 30% energy savings with current technologies and “normal” appearance

Conclusions

ASHRAE has heard and is responding to the requests of members to do more to giving guidance on how to design, build, and operate energy efficient buildings

The framework has been established for producing additional documents.
