ISO/TR 52000-2:2017 — Energy performance of buildings — Overarching EPB assessment — Part 2: Explanation and justification of ISO 52000-1. This technical report explains the procedures, background and justification for the choices made in ISO 52000‑1 and provides validation reporting and detailed examples to support correct understanding and national implementation.

Abstract

ISO/TR 52000-2:2017 is a supporting technical report to ISO 52000‑1 that provides explanatory material, background information, validation results for calculation procedures and worked examples intended to help users and national standards writers implement the overarching EPB methodology. The report clarifies procedures and justifies key choices made in ISO 52000‑1.

Scope

This technical report refers to the overarching EPB standard ISO 52000‑1 and contains material to support correct understanding, national implementation and use of ISO 52000‑1. It includes explanations of procedures and background, justification of choices, reporting on validation of calculation procedures given in ISO 52000‑1, and detailed examples for users and national standards writers.

Key topics and requirements

• Explanation and justification of the framework and procedural choices in ISO 52000‑1.
• Reporting on validation and verification of calculation procedures used to assess building energy performance.
• Background information and rationale to assist national implementation and adaptation.
• Worked examples and explanatory material for users, software developers and standards writers.
• Guidance to apply the overarching EPB assessment methodology for whole‑building energy evaluations.

Typical use and users

Primary users are national standards bodies and regulators, building energy assessors and certifiers, consulting engineers, building physicists, software developers implementing EPB calculations and policy makers seeking consistent methods for whole‑building energy assessment. The report is used as explanatory and implementation guidance alongside ISO 52000‑1.
