Full title and description

ISO/TR 52016-2:2017 — Energy performance of buildings — Energy needs for heating and cooling, internal temperatures and sensible and latent heat loads — Part 2: Explanation and justification of ISO 52016‑1 and ISO 52017‑1. This technical report provides explanatory material to support correct understanding and application of the calculation procedures set out in ISO 52016‑1 and ISO 52017‑1.

Abstract

ISO/TR 52016-2:2017 contains guidance, examples and rationale to clarify the hourly and monthly calculation methods for sensible and latent energy loads and needs, internal temperatures, and design heating and cooling loads. The report is non‑normative: it explains and justifies the procedures of ISO 52016‑1 and ISO 52017‑1 without adding mandatory provisions.

Scope

This Technical Report explains and justifies the calculation methods published in ISO 52016‑1 (hourly and monthly procedures for energy needs and internal temperatures) and ISO 52017‑1 (reference hourly method for sensible and latent loads). It clarifies routing of methods, key assumptions, required inputs and expected outputs, and gives background on the reorganisation of related ISO/CEN EPB standards (see Annex H for the rationale).

Key topics and requirements

• Explanatory guidance for hourly calculation of sensible and latent energy loads and internal temperatures.
• Clarification of the monthly calculation method for energy needs as referenced in ISO 52016‑1.
• Explanation of inputs and outputs: geometrical data, thermophysical properties, occupancy and internal gains, boundary and control conditions.
• Detailed discussion of design (sensible and latent) heating and cooling loads and their hourly calculation.
• Non‑normative examples, rationale, and an annex describing the relationship between this cluster of ISO/CEN standards.

Typical use and users

Intended users are building energy engineers, modelers, consultants, test laboratories, national standards bodies and regulators, and researchers who implement or interpret ISO 52016‑1 and ISO 52017‑1. The report is used to resolve implementation questions, check modelling assumptions, and justify method choices in compliance and design assessments.

Related standards

Directly linked to ISO 52016‑1:2017 (calculation procedures) and ISO 52017‑1:2017 (reference hourly method). It also sits within the wider ISO/CEN EPB cluster that includes ISO 52000‑1 and related technical reports and standards for climatic data, input parameters and EP indicators.

FAQ

Q: What is this standard?

A: ISO/TR 52016‑2:2017 is a non‑normative Technical Report that explains and justifies the calculation methods given in ISO 52016‑1 and ISO 52017‑1 for assessing energy needs, internal temperatures and sensible/latent heat loads.

Q: What does it cover?

A: It provides explanatory material, examples and rationale for hourly and monthly calculation methods, describes required inputs and outputs, and clarifies the structure and assumptions behind the EPB calculation procedures. It does not add mandatory requirements.

Q: Who typically uses it?

A: Building energy modelers, HVAC designers, compliance officers, national standards bodies and researchers who need guidance when applying ISO 52016‑1 and ISO 52017‑1.

Q: Is it current or superseded?

A: ISO/TR 52016‑2 was published in June 2017 (Edition 1) and remains the published technical report explaining ISO 52016‑1 and ISO 52017‑1. Users should check the ISO catalogue or national standards body listings for any later amendments or related technical reports, but there is no indication that ISO/TR 52016‑2:2017 has been withdrawn or superseded as of the latest public records.

Q: Is it part of a series?

A: Yes — it is part of the ISO 52000 series (energy performance of buildings) and the broader cluster of ISO/CEN EPB standards and technical reports that cover calculation procedures, climatic data, input parameters and EP indicators. ISO/TR 52016‑2 specifically supports ISO 52016‑1 and ISO 52017‑1.

Q: What are the key keywords?

A: Energy performance of buildings; heating and cooling needs; internal temperature; sensible and latent loads; hourly calculation; monthly calculation; design heating/cooling load.
