Abstract
EN ISO 52016-3:2023 specifies procedures for the calculation of the energy needs for heating and cooling, internal temperatures and sensible and latent heat loads of a building according to the hourly calculation methodology in ISO 52016-1, but modified for the situation that the building envelope contains one or more adaptive building envelope elements. These are building envelope elements with adaptive components that are either environmentally or actively controlled as a function of specific conditions.
For this purpose, the document provides detailed reference control scenarios for setting the state of the adaptive transparent building element on an hourly basis, depending on space category (residential, office), type of control and operation (manual, motorized, automatic, integrated), heating or cooling need, solar irradiance (~ daylight illuminance), indoor temperature, occupancy (resid.: active versus asleep [night]) and glare risk and minimum daylight level (for offices) and include corrections for occupant' interventions in case of automatic control and corrections for occupants' real (lower than ideal) response in case of manual control.
The adaptive building envelope element replaces the transparent building element in the calculation according to ISO 52016-1.
The three types of adaptive building envelope elements covered in this document are:
- Building envelope elements with dynamic solar shading
- Building envelope elements with chromogenic glazing
- Building envelope elements with an actively ventilated cavity
Environmentally activated control is described for building envelope elements with chromogenic glazing, but can also occur for other types of adaptive building envelope elements. In that case the same approach applies as for environmentally activated chromogenic glazing.
This document is applicable to the assessment of the energy performance of buildings (energy performance labels and certificates), including comparison between buildings and checking conformity with minimum energy performance criteria.
It is also applicable to assess the contribution of the adaptive building envelope element to the smartness readiness of a building.
In addition, this document provides indicators for the impact of the adaptive building envelope element on the performance of the building compared to a reference building envelope element. It is applicable to buildings at the design stage, to new buildings after construction and to existing buildings in the use phase.
NOTE 1 The background to the selection of adaptive building envelope elements is given in CEN ISO/TR 52016-4:2024, see link below.
