Slide1

The Research Centre on Zero Emission Buildings (ZEB) - About the ZEB Centre - Definition of Zero Emission Buildings - ZEB Demonstration ProjectsArild Gustavsen, Professor NTNUDirector The Research Centre on Zero Emission BuildingsSlide2

The main objective of the Research Centre on Zero Emission Buildingsis to develop competitive products and solutions for existing and new buildings that will lead to market penetration of buildings with zero greenhouse gas emissions related to their production, operation, and demolition.

The centre encompass

both residential, commercial,

and public buildings. www.zeb.no

Zero Emission Buildings - The Challenge:The main concept of a zero emission building is that renewable energy sources produced or transformed at the building site have to compensate for CO2 emissions from operation of the building and for production, transport and demolition of all the building materials and components during the life cycle of the building.

Zero Emission Buildings DefinitionSlide7

Zero Emission Buildings DefinitionZEB – COMPLETE: The building's renewable energy production compensate for greenhouse gas emissions from the entire lifespan of the building. Building materials – construction – operation and demolition/recycling.ZEB – COM: The building's renewable energy production compensate for greenhouse gas emissions from construction, operation and production of building materials.ZEB – OM: The building's renewable energy production compensate for greenhouse gas emissions from operation and from the production of its building materials.ZEB – O: The building's renewable energy production compensate for greenhouse gas emissions from operating the building.

ZEB – O - EQ

: The building's renewable energy production compensate for greenhouse gas emissions from operating the building minus the energy use for equipment (plug loads). This is the definition that most likely will be similar to a (nearly) zero energy building requirement.Slide8
