Testing renewable energy equipment: Space heating and warm sanitarian water production Setup of a test facility

Renewable energies are nowadays in the global spotlight. They can be used to generate electrical power on a large scale, but one should not forget domestic applications. Testing renewable energy equipment can be done outside, but for obvious reasons this most be done indoor also. Therefore one needs to simulate sunlight and thus lamps must be used. In order to fulfill the conditions imposed by the international standards, one must carefully examine what type of lamps can be chosen and how those lamps must be positioned in space. The present effort describes a methodology to set up an indoor test facility.
