Methodology for achieving non-residential zero-energy buildings (ZEBs)

This document provides a basic step-by-step approach for achieving non-residential (net) zero-energy buildings (ZEBs). It also describes the basic concept of ZEBs and the items for consideration in this approach. The following are within the scope of this document: — application to non-residential buildings; — annual energy consumption of a ZEB (this includes the operating consumption of the building and excludes the energy consumed by the manufacturing of materials and equipment, and the energy consumed during construction); — renewable energy supply (this can be on-site or off-site, depending on the policy and conditions of the country in which the supply is installed); — application to any climate zone. The following are out of the scope of this document: — recommendations or suggestions for the adoption of any specific technologies and/or equipment and materials that are expected to be continuously innovated (however it does stipulate the technologies for selection); — specific methods or calculation formulae; — commissioning methods.
