Cel IN THIS PROJECT COMPUTER MODELS HAVE BEEN DEVELOPED WHICH SIMULATE THE THERMAL BEHAVIOUR OF BUILDINGS. BASICALLY THREE SIMULATION MODELS HAVE BEEN MADE : - SIMPLE STEADY STATE MODELS FOR ONE AND MULTI ZONE PROBLEMS (LPB 3 AND LPB 4 RESPECTIVELY). - A SIMPLE DYNAMIC MODEL LPB 5. - DETAILED DYNAMIC MODELS LPB 1 AND LPB 2. IN THESE MODELS THE CONCEPT OF A "TEMPERATURE WITHOUT HEATING" TWH WAS INTRODUCED WHICH TAKES INTO ACCOUNT THE GRATUITIOUS ENERGY SUCH AS SOLAR RADIATION. TWH IS A VERY IMPORTANT CHARACTERISTIC OF A BUILDING AND IS NEEDED TO CALCULATE THE ENERGY DEMAND OF A BUILDING. A FORMULA HAS BEEN DEVELOPED BY WHICH TWH CAN BE CALCULATED FROM A LIMITED NUMBER OF CLIMATIC DATA. THE AGREEMENT WITH EXPERIMENTAL DATA WAS VERY SATISFACTORY. A SECOND CONCEPT USED IN THESE MODELS IS THE "EQUIVALENT DEGREE-DAY" WHICH IS THE SUM OF TNH - TWH WHERE TNH = TI - (DELTA)TOCC. IN THIS FORMULA TI IS THE IN-HOUSE TEMPERATURE OF A HEATED HOUSE AND (DELTA)TOCC THE TEMPERATURE INCREASE IN THE HOUSE DUE TO OCCUPANTS, DOMESTIC APPLIANCES, ETC. A PRACTICAL STEADY STATE METHOD HAS BEEN DEVELOPED TO ESTIMATE THE HEATING ENERGY DEMAND THROUGH TABLES OF EQUIVALENT DEGREE-DAYS (LPB 3 AND LPB 4), TAKING INTO ACCOUNT EXTERNAL TEMPERATURES, WIND, DIRECT AND INDIRECT SOLAR RADIATION. THIS STEADY STATE MODEL WAS EXPERIMENTALLY VALIDATED IN TWO REAL HOUSES AND TWELVE TESTBOXES OF 1 M3. THE SIMPLE DYNAMIC MODEL LPB 5 HAS BEEN DEVELOPED AND EXPERIMENTALLY VERIFIED. DETAILED DYNAMIC BEHAVIOUR OF TESTBOXES WAS STUDIED WITH LPB 1 AND LPB 2. THE TESTBOXES HAVE BEEN SHOWN TO BE A VERY USEFUL ANALYTIC TOOL. A LIMITED SET OF STANDARDIZED TESTBOXES COULD ALSO BE USED AS A REFERENCE IN ORDER TO DEFINE EXPERIMENTALLY THE CLIMATE IN VARIOUS LOCATIONS IN EUROPE. FINALLY, IN COLLABORATION WITH THE UNIVERSITY OF LIEGE (CONTRACT EE-A5-060), PRACTICAL GUIDELINES HAVE BEEN DEVELOPED FOR THE ENERGY SAVING DESIGN OF BUILDINGS.
