Figure 3. Energy use (delivered energy) for heating and hot water per heated area in multi-dwelling blocks between 1970 and 2002. 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)
Figure 2. Energy use (delivered energy) for heating and hot water per heated area in small houses between 1970 and 2002. 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)

Low-energy houses
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

- Concrete carcass gives more even temperature- Well insulated external walls and floors
- Design for optimal solar incident radiation/solar control (winter/summer)
- Electricityefficient (A++) domestic appliancies
- Demand-controlled ventialtion
- Water.. (vattensnål armatur)
- Electricityefficient luminaire
- Individual measurement
-Hot water accumulator
-Waste water heat-exchanger
