Komponenten und Materialien für die passive Nutzung der Solarenergie
Abstract
A reduction of heating energy for houses affects the consumption of primary energy sources appreciably, and therefore should be a primary aim of energy politics. Heat insulation alone is not sufficient as only heat transmission losses are dealt with. Passive solar energy utilization is the most promising way to reduce the energy demand further on by trying to match losses with solar gains. Apart from heat, good passive solar design also considers light, humidity and air transport to optimize human comfort. An optimization of the solar apertures of a house therefore needs a variety of materials to make a design possible which is best adapted to environment and requirements of the inhabitants. Transparent insulation materials as collector covers, starting from simple glazing, are the key materials, which are described in this article. Existing materials, solar transmission, heat transport and problems of application are covered, while no importance is laid on design variations of the fun damental generic apertures window and collector wall.
