Ventilation
Energy-saving cycles.
Modern ventilation systems deliver air that is both healthy for breathing and healthy for buildings, in that it helps to prevent fungal growth. They also make a major contribution to savings. These systems retain up to 90 % of the energy conventionally lost by airing through opening windows, and return it to the heating circuit. So you don't throw your money out the window.
