The aim of passive design is to respond to the external climate using primarily structural means to achieve a comfortable indoor climate. The use of building technology is an additional measure. This paper compares the demand for resources, primary energy, and thermal and air-hygienic comfort of passive and climate-unadapted designs to determine the most energy-efficient and sustainable design. It also analyses whether user comfort suffers from reduced use of technical building equipment. For this purpose, a representative passive building model is compared with a climate-unadapted one. Comfort, primary and embodied energy are determined and compared by way of a simulation and life cycle assessment. The passive design presents a lower primary energy demand than the climate-unadapted one, even when embodied energy is taken into account. While the requirements of air-hygienic comfort are fulfilled equally in both types of buildings, the passive design displays better thermal comfort. This indicates that energy can be saved by employing a passive design.
