Existing buildings New buildings Low-energy houses Delivered energy per heated area (kWh/m 2,year) Figure 3. Energy use (delivered energy) for heating and hot water per heated area in multi-dwelling blocks between 1970 and The graph of existing buildings represents total heated area during the current year and the graph of new buildings shows the energy use when work is finished. Examples of measured values from recently built low-energy houses illustrate the distance to Best Available Technology. (All data adjusted to average weather year)

Energyefficient buildings – House without heating system - Passivehouse Strategy: Minimizing energy losses = effective energy management Measures: Very well insulated building envelope Minimal air leakage Mechanical ventilation with very high heat recovery Solar energy for hot water Waste water recovery
