System description

The single-family house was built in 1980, but completely renovated in 1998. In the process of renovation, the insulation was improved and a solar combisystem was added. The outer walls and the roof are fitted with 20 cm of insulation material. The average specific heat loss rate is 0.3 W/rmK. The windows have a tf-value of 1.4 W/m2K.

All rooms are on one floor. The heated area consists of one living room, four bedrooms, a kitchen and corridor...

System description

The largest application areas for solar combisystems in the Netherlands are detached houses and rows of single-family houses. Typical building materials for these houses are concrete for construction, combined with brick and gypsum for the other walls. The outer walls are double, with about 10 cm of insulation material. The roof is also insulated and can be flat or pitched. Windows are double-glazed...

System description

This single-family house was designed for very low energy consumption. The outer walls are built with a wooden framework and are filled with 26 cm thick cellulose insulation. The roof insulation also has cellulose insulation, with a thickness of 38 cm. The windows are double-glazed and have a 17-value of 0.9 W/m2K. In order to reduce the ventilation heat losses, a mechanical ventilation system with heat recovery is installed. A soil-to-air heat exchanger provides frost-protected air in winter and pleasantly cool air in summer.

The heat distribution takes place via radiators that are designed to operate at flow/return temperatures of 55°/45°C for an outside air temperature of—12°C.

Heat and electricity to the building are supplied 100% by renewable energy sources, that is, solar energy
