Line 95: Line 95:
 A cogeneration unit next to the building produces electricity and heat with gas from the water purification process (Figure 4). The heat is exported to a district heat network for use in space heating and hot water. The cogeneration share of heat is estimated at 94 percent. The lines are very short, so losses are low. The biogas from purification has an PER factor of 1.1, but only within the biomass budget of 20 kWh/(m²a) PER. Within that budget, the PER factor is 0.53, which results in an efficiency factor of the grid of 85% and a cogeneration share of 94% (with 46% electricity and 44% heat). Then, the biogas is considered to have a PER of 1.75, and the factor worsens to 0.93. Although the hot water distribution system is relatively inefficient, the initial PER demand is 44.3 kWh/(m²a). With the 247 square meters of PV covering 35% of the roof, the Passive House Plus level is reached. A cogeneration unit next to the building produces electricity and heat with gas from the water purification process (Figure 4).
