Full title and description

Energy performance of buildings — Energy needs for heating and cooling, internal temperatures and sensible and latent heat loads — Part 1: Calculation procedures. ISO 52016-1:2017 specifies calculation procedures (hourly and monthly) to determine sensible and latent energy needs, internal temperatures and heating/cooling loads for buildings or building zones, supporting design, compliance assessment and energy performance evaluation.

Abstract

ISO 52016-1:2017 defines methods to calculate: (a) sensible energy needs for heating and cooling (hourly or monthly), (b) latent energy needs for humidification/dehumidification (hourly or monthly), (c) internal temperatures (hourly), (d) sensible heating and cooling loads (hourly), (e) latent loads for humidification/dehumidification (hourly), (f) design sensible and latent heating/cooling loads using hourly intervals, and (g) supply-air conditions required to provide humidification/dehumidification. Procedures are applied per thermal zone and may include interaction with building systems and controls; they are intended for use at design stage, for new buildings and for existing buildings in use.

Scope

This standard provides calculation procedures for determining building energy needs and loads related to heating, cooling, humidification and dehumidification and for calculation of internal air and operative temperatures. Calculations are performed per thermal zone and may be carried out using hourly (preferred for most quantities) or monthly intervals (allowed for energy needs). ISO 52016-1 is applicable to residential and non-residential buildings, or parts thereof, and can be used for design-stage assessments, post-construction verification and in-use performance evaluations. The methods cover both basic (system-independent) load/need calculations and system-specific interactions including supply-air conditions and control strategies.

Key topics and requirements

• Hourly and monthly calculation procedures for sensible and latent energy needs.
• Calculation of internal air and operative temperatures (hourly, transient conditions).
• Determination of sensible and latent heating and cooling loads, including design loads using hourly intervals.
• Thermal zone definition and treatment (thermally coupled or uncoupled zones).
• Options to include interactions with HVAC and other technical building systems and control strategies.
• Specification of boundary conditions, assumptions and reference indoor/outdoor conditions for calculations.
• Provision for supply-air conditions required for humidification and dehumidification.
• Intended as a basis for software implementations, energy certification and regulatory compliance.

Typical use and users

Used by building energy modelers, HVAC designers and consultants, building simulation and certification software developers, regulatory authorities and certification bodies, researchers and academics. Typical applications include design-stage energy needs assessments, sizing of heating/cooling systems, energy performance certification, compliance with national/regional regulations and comparative studies of building performance and retrofits.

Related standards
