The objective of this report is to provide a comprehensive and consistent guideline for the Norwegian definition of Zero Emission Buildings (ZEB) and the associated calculation methodologies. The guidelines described in this report build upon the article "A Norwegian Zero Emission Building Definition”, the report “A Norwegian ZEB Definition - Embodied Emissions” as well as other relevant national and international work. The guidelines explain the methodology used within the ZEB Research Centre, focusing upon operational energy use calculations and life cycle emission calculations for materials. Furthermore, the guidelines illustrate the ZEB definition and methodology with selected examples from the ZEB pilot case studies. This guideline is useful for designers and developers involved in the planning and design of zero emission buildings. The guideline can also be used as a point of reference for the setting of future standards and regulations on low carbon buildings
