Apartment related energy performance gap – How to address internal heat transfers in multi-apartment buildings
Highlights The influence of building physics and occupant behaviour on the heating energy consumption in multi-apartment buildings is compared with a particular focus on the interaction effects between these two. Internal heat transfers between apartments caused by internal temperature differences play an important role in the explanation of the energy performance gap at the household level. Apartment specific energy demands are predicted based on building information and hourly data of indoor and outdoor temperatures. Different types of occupant behaviour influence the space-heating energy consumption, not only of the household itself but also their neighbours. Understanding the energy performance gap at the apartment level requires a better understanding of the relationship between building physics and occupant behaviour within and between apartments.
Abstract Households’ heating energy consumption is one of the most important sources of a nation's total CO2 emissions. But there remains uncertainty about the impact of occupant behaviour on heating energy consumption, especially in multi-apartment buildings. In bringing together apartment specific data of occupant behaviour and physical building properties of multi-apartment buildings, the quantitative influence of different factors determining apartments’ heating energy consumption can be separated by means of OLS-regression. For multi-apartment buildings the heating energy consumption of a single apartment seems to be determined not only by the behaviour of households in opening windows and using radiators but also by internal heat transfers, triggered by temperature differences between neighbouring apartments. This study shows some limits of refurbishment policies and consumer education and points to the importance of considering both data on occupant behaviour and building physics at the apartment level together to understand households’ heating energy consumption.
