Abstract | Heating load and building relative humidity in winter are affected by over-all air infiltration and ventilation rates. Since windows and doors usually represent the major source of air leakage in buildings, significant reductions of overall air infiltration are achieved principally by increasing the air-tightness of these components. Reduction of the air infiltration rate through windows, however, will not reduce exfiltration through other cracks and porous condensation. To overcome condensation problems resulting from exfiltration, cracks and porous construction must be eliminated on the warm side of the structure. In multi- story buildings air flow between floors should be restricted to reduce pressure differences resulting from chimney action. |
