"Obtaining rooflights that meet the requirements of Passivhaus design has until recently been near impossible. Whilst invaluable in designing in additional light to a building the dangers of over-heating can not be overlooked . On south faces particularly provision must be made in the form of blinds to prevent this happening. "
