Terms like "net zero energy", "zero net energy", "net zero carbon" or "EQuilibrium" buildings are in widespread use. But these terms have different meaning and are poorly understood, even though several IEA countries have adopted them as goal of their building energy policies.
IEA SHC project "Task 40" aims at filling this gap with a clear definition and international agreement on the measures of building performance that could inform "zero energy" building policies, programmes and industry adoption.
Published results of this project include:
- Net Zero Energy Building. Living and Working with an Equalised Energy Balance (Book published by detail.de)
- Zero Energy Building Definition – A Literature Review (PDF, 16 pages)
- Description of Simulation Tools Used in Solar Cooling (PDF, 95 pages)
And many (partly peer-reviewed) papers, e.g.:
- Net zero energy buildings: A consistent definition framework (PDF, 13 pages)
- Zero Energy Building: A Review of Definitions and Calculation Methodologies (PDF, 9 pages)
- Strategies for Reducing Peak Demand in Net-Zero Energy Solar Homes (PDF, 11 pages)
