MaTriDMarket transformation towards nearly zero energy buildings through widespread use of integrated energy design

● Supports the implementation of Nearly Zero Energy Buildings by 2020 by widespread use of Integrated Energy Design (IED)

● Integrated Energy Design (IED) is a approach to organise the complexity of the design process and facilitate the interactions between the members of the design team.

● Participating Countries Austria, Greece, Italy, Portugal, Norway, Sweden, Slowenia, Slovakia, Poland,

Latvia, UK


Benefits of Integrated design

● Less mistakes during the design phase

● less mistakes and design changes during construction

● reduced life cycle costs of building

● higher energy efficiency and sustainability of the building

● higher satisfaction of design team members

● higher satisfaction of the building user

● better image due environmental friendly thinking


Main barriers of Integrated Design

● Conventional thinking

● Costs of Integrated Design

● Time constraints in initial design phase

● Competitive areas of expertise

● Missing defined goals3% design costs

17% construction costs

78% operation costs2% disposal costs


Challenges of the design team

Energy & Supply

Net energy ‐ heating demand‐ cooling demand

‐ architectural concept (orientation, compactness, glazing area, shading)‐ building physic specific values‐ thermal mass‐ airtighness

■ ■ ■ ■ ■

End energy, primary energy demand ‐ end energy demand ‐ lighting demand‐ ventilation and air conditioning demand‐ overall energy efficiency‐ primary energy demand‐ energy generation

‐ architectural concept (orientation, compactness, glazing area, shading)‐ building physic specific values‐ thermal mass‐ heating, ventilation, cooling, electrical installations (distribution and und supply systems, regulation system)‐ renewable energy‐ airtightness

■ ■ ■ ■ ■ ■

Energy monitoring ‐ equipment for energy monitoring ‐ hardware and software‐ Automatization concept‐ metering structure (electricity, heat, water)

Renewable enery, CO2‐emissions ‐ energy generation ‐ primary energy demand‐ renewable energy‐ CO2 emission

■ ■ ■ ■ ■

Drinking water demand ‐ sanitary facilities‐ area to be cleaned and cleaning intervals‐ use of rainwater‐ use of grey water‐ infiltration and leaching to groundwater

‐ architectural concept (glazing area)‐ water saving taps‐ Floor and wall coverings‐ water use concept (use of rain‐ and greywater)‐ Greening, sealing of outdoor facilities

Systematic putting into service ‐ measurements and protocols for commissioning and putting into service

‐ Function tests of components‐ hydraulic adjustments

Integrated Design –the new way of collaboration during design


Teambuilding

● Integrated Design Kick off

● Agenda Presentation of the common goals Definition of integrated design

iterative problem solving

Definition of ways of collaboration Interfaces between team members Know-how transfer

Mayor barriers and how to overcome them Definition of milestones and control mechanism


Iterative problem solvingthe building design phase

critical thinking creative thinking

Analyse the problem

Evaluate solutions and choose one

Implement the solution

Critique the solution

Make improvements

Innovate the solution

Brainstorm solutions


On track monitoring

● Use goals/ targets as means of measuring success of design proposals

● Make a Quality Control Plan


Delivery

● Ensure that the goals are properly defined and communicated in the tender documents and building contracts

● Motivate and educate construction workers and apply appropriate quality tests

● Facilitate soft landing. Make a user manual for operation and maintenance of the building
