Investigation of the relationship between the natural ventilation of a flat and meteorological conditions.

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.
