Capturing Building Fabric Thermal Performance and Solar Heat Gains Through a Whole House Heat Loss Test – an In-Situ Study in Poland

“…The most simple methods of connecting the energy used for heating with the heat transfer through the building envelope with the use of the co-heating test excluded solar gains from the analyses [2,7,11].…”

“…It was explained by the relatively low contribution of radiation reaching the building's interior compared with the other components of energy balance and energy use [7]. Practically it could be done by reducing observation periods only to nights or overcast days.…”

“…However, understanding of the test's applicability has widened in recent studies, with the test applied to measure HLC of thermal bridges [6] and attempts to evaluate solar heat gains. The need for further research in the latter area has been identified in [7]. This paper discusses the results of a co-heating test that addresses the challenge of capturing solar heat gains contribution through a co-heating test to contribute to a more nuanced understanding of HLC under different external conditions.…”

Assessing the co-heating test as reference for heat loss coefficient estimation: In-depth analysis on an artificial dataset

“…The significance of different components of the heat balance was further explored by several authors, especially the incorporation of solar gains into the models [24], [25]. The impact of neighbouring zones and the weight of the building structure [17], [21], [26] were also separately investigated, as well as the feasibility of replication of the experiment in different climates [27], [28]. Research on the co-heating test also evolved towards the usage of the building's own heating system [29] and adaptation to in-use buildings [30].…”
