This document describes a method for measuring the insulation performance of building elements, e.g. exterior walls, floors, ceilings (hereinafter referred to collectively as "walls"). This is done by using the probe insertion method, which gives the temperature distribution in the wall with a temperature sensor in a small diameter borehole in the wall. The measurement method is divided into a quantitative method, which measures the thermal resistance with a heat flow measurement, and a qualitative method without heat flow measurement. This document describes a screening test that is used for preliminary and practical diagnosis. The method is applicable to plane building components with a light heat capacity, such as those in frame structure dwellings. The measured results give the insulation performance at the local measurement points rather than that of the whole panel including thermal bridges such as studs.

This document 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. Additions or modifications of the calculations are provided in this document if the building envelope contains one or more adaptive building envelope elements (building envelope elements with adaptive components that are either environmentally or actively controlled as a function of specific conditions). 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 (EPB) (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 smart 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. This document is not applicable to geometrically complex adaptive building envelope elements that can only be modelled as multiple coupled thermal zones. NOTE The background to the selection of adaptive building envelope elements is given in ISO/TR 52016-4.

This document specifies the choices to be made to calculate the PEFs and CO2 emission coefficients related to different energy carriers. PEFs and CO2 emission coefficients for exported energy can be different from those chosen for delivered energy. This document is primarily intended for supporting and complementing ISO 52000-1 as the latter requires values for the PEFs and CO2 emission coefficients to complete the EPB calculation, however it can also be used for other applications.
