The main design objective of ENERPOS was to construct a low-energy
building (energy use intensity of 14 kWh FE /m 2 /yr, FE for final energy)
using primarily passive design principles, while maintaining visual and
thermal comfort for the occupants. Thus, priority was given to indoor
environment and energy efficiency measures, natural ventilation, solar
