Objective
Energy saving measures in buildings are of great economical and ecological importance : about 43% of the end energy consumption of the Federal Republic of Germany are allotted to space heating. Improved heat insulation combined with optimized heating and control techniques may reduce the heating energy demand, but remaining heat transmissions and in particular ventilation losses cannot be avoided completely.
A further reduction of the energy requirement calls for new concepts. In this context passive solar measures are of great importance, because they are able to compensate heat losses by solar gains. The ISFH has built two experimental houses to demonstrate buildings with minimized heating loads and for testing the effectiveness and the economy of passive solar components and systems.
The specific heat consumption of the reference house is 55 kWh/m2. The specific heat consumption of the solar test house is 40 kWh/m2. Thus, the already low heating energy needs of the buildings (low energy building standard) could be diminished by 25% through solar measures.
The site is situated in the municipality of Emmerthal south of the city of Hameln. Particular characteristics of the buildings are : large south facing windows for direct gains, transparently insulated solar walls, a conservatory as preheater for ventilation air, opaque insulation better than the swedish standard, advanced glazing, temperature zoning, a standard gas central heating system with low capacity radiators and a computerized energy management to ensure maximum use of solar gains. The performance of the passive solar design is continuously monitored, including climatic data.
A basic idea of the project is to use one house as the experimental one and the other as a reference. Both houses are nearly identical, except for the solar components under investigation. Test-reference experiments can be carried out that way, which allow a direct assessement of the solar gains.
