Abstract: This paper examines the feasibility of utilising solar energy to heat buildings having galvanised iron sheet roofs with false ceilings beneath. Numerical predictions are presented for a typical roof area of 2200 m2, below which air is blown at a speed of 2·16 km/h. If, for proper ventilation, the inside air is replaced by fresh air three times an hour, then to maintain the inside temperature at 21·1°C throughout the day, auxilary heating is necessary only in the morning and late evening. For the rest of the day, the solar heat is sufficient to maintain this temperature.
