Outlines necessary ventilation rates for an occupied room. Discusses natural ventilation of a room through openings in the ceiling. Discusses natural draught ventilation for single family houses, combined natural draught and mechanical ventilation, mechanical fresh air ventilation based on a central duct, fortuitous ventilation caused by air infiltration and leakage. Compares natural and mechanical ventilation. Considers supplyair systems for single family houses, warm air heating and possibilities for heat recovery.
Investigates energy balance of centrally heated flat at coastal town of Kijkduin, based on daily figures of gas consumption and ventilation losses derived from meteorological conditions. Studies: 1) pressure difference over the building caused by windvelocity, wind direction and outdoor air temperature; 2) natural ventilation caused by pressure differences over fortuitous cracks and intentional opening of windows, grilles and shafts. Studies possibility of ventilation prediction via mathematical model.
