Two Years of Experience with a Net Zero Energy Balance - Analysis of the Swiss MINERGIE-A Standard

Abstract

With the net zero energy balance for heating, domestic hot water, ventilation and auxiliary energy, the Swiss MINERGIE-A Standard is a major step towards standardized, economically feasible net zero energy buildings. Not only the zero energy balance but also the requirement for limited embodied energy is a new challenge for architects and designers. In the two years since the launching of the Standard and the writing of this paper, approx. 240 buildings have been certified or pre certified. The new standard is widely accepted and its challenges are appreciated in the building sector. A cross analysis shows that a wide range of different energy concepts and embodied energy strategies are possible in the scope of the Standard. The wide variety of options is one of the main findings of the rollout of this new zero-balanced standard.
