Overview

EN ISO 52016-1:2017 - "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) is a CEN-adopted international standard that defines validated calculation methods to determine building heating and cooling energy needs and loads. It covers both hourly and monthly calculation procedures, applies per thermal zone, and can be used for residential and non-residential buildings at design, post-construction or in-use stages. The standard supports consistent building energy performance assessment within the EPB (energy performance of buildings) standards framework.

Key topics and requirements

• Energy needs and loads: Methods to calculate (sensible) energy needs for heating and cooling and latent energy needs for humidification/dehumidification.
• Internal conditions: Calculation of internal temperatures (hourly) and sensible and latent heat loads (hourly), including design loads using hourly intervals.
• Zoning and thermal coupling: Procedures for defining thermal zones, treating zones as thermally coupled or uncoupled, and assessing heat exchange between zones.
• Time resolution: Both hourly and monthly procedures are specified; hourly methods can underpin advanced system control and design calculations.
• System interaction: Methods for basic energy loads (building-only) and system-specific loads that include interaction with HVAC and supply-air conditions.
• Moisture and supply air: Calculation of moisture content, latent heat loads and supply-air conditions required for humidification/dehumidification.
• Inputs and outputs: Guidance on geometrical, thermophysical, operating and boundary data, and required outputs such as heating/cooling needs, peak design loads, and monthly key data.
• Applicability: Suitable for design-stage simulations, new buildings, and existing building energy assessments.

Practical applications and users

EN ISO 52016-1:2017 is used to produce robust, comparable results for:

• HVAC designers and engineers - sizing heating, cooling and dehumidification systems; determining design sensible and latent loads.
• Energy assessors and modelers - compliance checks, energy certification and performance benchmarking.
• Architects and building designers - informing passive design choices and indoor climate targets.
• Policy makers and certification bodies - consistent methodology for national/regional EPB schemes and compliance with EU EPBD-related mandates.
• Building managers - evaluating retrofit scenarios and operational energy needs.
