Abstract
In connection with the renovation of older buildings, interest in using solar energy in solar walls is growing. The use of solar walls can help to reduce energy consumption and also help to protect the outer walls, which they cover, from the ravages of the weather - thus saving on maintenance costs. The solar energy can preheat the ventilation air. The aim of the project was to develop a combination of extra insulation and a solar wall - a solar wall energy diode. The building`s ventilation system sucks in air through an absorber made of mineral wool so that energy from the absorber is transferred to the ventilation air which is thus heated. When the sun shines on the solar wall the mineral wool is warmed, when it doesn`t, the energy diode functions as a countercurrent insulation and part or all of the heat loss from the rooms through the wall is absorbed by the air and carried back to the house as preheated ventilation air. This means that solar heat is led into the building and the loss of energy through the walls is reduced. A mathematical model and a calculation programme for the analysis of the solar energy
