An investigation of technical and hygienic aspects of energy saving by reducing mechanical ventilation in a block of flats. Onderzoek naar de mogelijke energiebesparing en technische en hyienische aspekten van het verminderen van de mechanische ventilatie

Measurements were made of the apparent volume flows in the mechanical ventilation system of a block of flats, along with the expected energy arising from domestic ventilation. The aim was to see what energy saving could be obtained by reducing the mechanical ventilation in the block of flats. It was found that this depended on the reaction of the occupants. If they opened an extra vent light for a few hours per day, then the energy losses due toventilation were higher then before the reduction of the mechanical ventilation. It was suggested that the lowering of ventilation rates would not damage health, and the build up of odour would not be noticeably enhanced. Whether condensation problems would occur needs to be investigated further.
