Abstract: Hypocaust, an ancient Roman concept for keeping the inside of buildings warm, has been explained with a survey of a few modern buildings based on these concepts and using solar heat employing a number of design variations.Results expressed in terms of energy requirements per m1 of flcor area per degree day comes out to be minimum 15.4kJ m1 per DD per annum for a solar chimney and maximum for solar air collectors 128.4 kJ m1 per DD per annum The basic parameters that determine the performance of a hypocaust construction are size of the cavity determining the heat transfer between the flowing fluid and the building component and the storage capacity of the hypocaust element.The optimum width of the cavity comes out to be between 49 mm and 099 mm. Heat storage capacity of the building element used as hypocaust corresponds to 0.125 K temperature rise per hour in relation to the building heat load.
