 If a small solar thermal array for hot water supply with six square meters of collector area is added, PER demand drops to 47 kWh/(m²TFA*a), while energy generation increases to 65 kWh/(m²ground*a) (1a). In terms of energy generation, the level of Passive House Plus is reached, and we are not far away in terms of demand either. In this variant, the building already generates slightly more final energy than it consumes. If the collector area triples to 18 square meters, however, PER demand drops even further to 43 kWh/(m²TFA*a), which fulfills Passive House Plus. However, the effects are minor (especially in the light of the high cost of three times more collector area) because the additional energy produced in the summer cannot be completely used; the hot water tank (now 2,000 liters) will be fully loaded (1b). If a small solar thermal array for hot water supply with six square meters of collector area is added, PER demand drops to 47 kWh/(m²TFA*a), while energy generation increases to 65 kWh/(m²ground*a) (1a).
