New development of 20 terrace houses without a traditional heating system:

• Extremely well insulated and very airtight
• Equipped with a high efficiency ventilation heat recovery system to heat supply air
• Remaining heat requirement covered by heat from occupants, appliances and lighting
• Each house also has a 5 m² solar collector designed to cover 50% of the energy supply for hot water use
• Cost is estimated to be about the same as traditional construction
• Ongoing monitoring for research into the effectiveness of the development
