Description (English):

ISO/TR 52016-2:2017 contains information to support the correct understanding and use of ISO 52016‑1 and ISO 52017‑1. These documents give calculation methods for the assessment of: - the (sensible and latent) energy load and need for heating and cooling, based on hourly calculations; - the (sensible and latent) energy need for heating and cooling, based on monthly calculations (ISO 52016‑1); - the internal temperature, based on hourly calculations; and - the design (sensible and latent) heating and cooling load, based on hourly calculations. ISO/TR 52016-2:2017 does not contain any normative provisions. NOTE A description of the rationale behind the reorganization of the cluster of strongly related and partly overlapping ISO and CEN standards is given in Annex H.

Abstract

Overview

CEN ISO/TR 52016-2:2017 (ISO/TR 52016-2:2017) is a Technical Report published by CEN to explain and justify the calculation methods given in ISO 52016‑1 and ISO 52017‑1. It is an explanatory, non‑normative document that supports correct understanding and practical application of methods for assessing building energy needs for heating and cooling, internal temperatures, and sensible and latent heat loads. The report clarifies method routing, assumptions, inputs and outputs, and the rationale for the standard structure (see Annex H).

Key topics

Scope and purpose: Guidance to correctly use ISO 52016‑1 (hourly and monthly calculation methods) and ISO 52017‑1 (reference hourly method).
Calculation methods covered:
- Hourly methods for energy load, internal temperatures and design heating/cooling loads (sensible and latent).
- Monthly method for energy needs (sensible and latent) as defined in ISO 52016‑1.
Input and output data: Explanation of required geometrical, thermophysical, operating and boundary condition data, and the expected calculated outputs.
Zoning and thermal coupling: Guidance on thermal zoning, zone sizing, heat exchange between zones and adjacent unconditioned spaces.
Procedure details: Routing of calculation steps, time intervals, iterative loops between inputs and outputs, and handling of ventilation and internal gains.
Comparative context: Explanation of differences between ISO 52016‑1 and earlier standards it supersedes (e.g., ISO 13790:2008).
Non‑normative guidance: Explanatory examples, rationale for method choices, and practical clarifications-not prescriptive requirements.

Applications

Building energy assessors and modelers: Use the TR to ensure correct application of hourly and monthly calculation procedures for energy needs and loads.
HVAC designers and engineers: Reference the explanations for deriving design sensible and latent heating/cooling loads and internal temperature profiles.
Certification bodies and regulators: Apply consistent, transparent methods when implementing national/regional energy performance requirements and EPBD compliance.
Policymakers and standardization committees: Leverage the rationale and method justification when adapting standards to local climates, policy choices or regulatory boundaries.

Who should use it

Energy consultants, HVAC engineers, building physicists, certification authorities, and national standards bodies implementing CEN/ISO EPB (energy performance of buildings) standards.

This Technical Report is valuable for anyone implementing or interpreting ISO 52016‑1 and ISO 52017‑1 to achieve accurate, consistent assessments of building heating/cooling needs, internal temperatures, and sensible/latent heat loads.
