Summary

IN MOST EUROPEAN COUNTRIES TRANSMISSION HEAT LOSSES THROUGH EXTERNAL BUILDING ELEMENTS HAVE BEEN CALCULATED FOR MANY YEARS ON THE BASIS OF AN ILL-DEFINED INTERNAL TEMPERATURE, BUT WITH CONSTANT HEAT EXCHANGE COEFFICIENTS AT THE INNER SIDE OF THE BUILDING ELEMENTS. THE PAPER CONCLUDES THAT CONSTANT HEAT EXCHANGE COEFFICIENTS ARE SATISFACTORY IF DRY RESULTANT TEMPERATURE IS TAKEN AS THE INTERNAL TEMPERATURE. THE ADVANTAGE OF THIS USAGE IS THAT IN MOST CASES THE DRY RESULTANT TEMPERATURE IS KNOWN A PRIORI BECAUSE IT CORRESPONDS FOR PRACTICAL PURPOSES WITH THE DERIVED COMFORT TEMPERATURE IN THE ROOMS.
