PD ISO/TS 23764:2021

This standard PD ISO/TS 23764:2021 Methodology for achieving non-residential zero-energy buildings (ZEBs) is classified in these ICS categories:

• 91.040.01 Buildings in general

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.
