EN Thermal balance and indoor environment quality of energy efficient homes is strongly influenced by residents’ practices. Despite a growing body of literature on building - occupant interaction an interdisciplinary perspective is required for an understanding of the dynamics of households operating in energy efficient homes and the motivations underpinning the observed indoor environment control practices. This paper reports preliminary results of a one year long in-depth performance evaluation of almost identical six semi-detached energy efficient homes in Poland. All homes are equipped with heat pumps and MVHR ventilation, however the systems vary between buildings, and two homes use wood stoves. The aim was to capture the home use practices settled after the adaptation process of early occupancy. Data collection lasted between September 2021 and August 2022. Energy consumption data was provided by an energy supplier. The preliminary results reveal very high quality of the internal environment, with some overheating issues of varied severity. The results also point to the key role of performance indicators for meaningful comparisons of energy consumption data between households of varied size living in same size dwellings. Occupancy intensity (personmonths) is aligned with the increased energy consumption, therefore standard results presentation in (kWh/m2/a) may be misleading.
