DESCRIBES AN EXPERIMENTAL SURVEY B BRITISH GAS OF LEAKAGES FROM 200 TIGHT DWELLINGS, POSSIBLY THE LARGEST SURVEY OF ITS TYPE IN THE UK. EXPLAINS THE MECHANISMS OF NATURAL VENTILATION AND INFILTRATION AND HOW VENTILATION HEAT LOSSIS CALCULATED. DESCRIBES THE TEST PROCEDURE AND INSTRUMENTATION AND ILLUSTRATES THE BASIC TECHNIQUE OF LEAKAGE MEASUREMENT. FINDS THAT TIMBER FRAME DWELLINGS ARE APPROXIMATELY HALF AS LEAKY AS TRADITIONAL DWELLINGS OF THE SAME VOLUME. LEAKAGE TENDS TO INCREASE WITH VOLUME. (INT. BUILD. SERV.
