| Abstract | To increase the surface temperature of a metal window system for a portion of a new building (less than 5% of the windows) in order to permit 50% relative humidity at 22 degrees C without condensation, the following techniques were investigated: triple glazing by use of a double-sealed unit in an exterior frame and single-glazed interior frame; pressurization of the air space between the inner and outer frames, with dry air at room temperature; and provision of supplementry heat to the sill of the inner single-glazed frame. The total energy consumption for the pressurizing air and sill heater for the winter period October 1981 to April 1982 was 166 MJ per meter of window width. It is suggested that such an approach might prove economical in situations where a small portion of a building has unique occupancy requirements, or where an occupancy change requires retrofitting of a window system. |
