The following notes were produced "on line", during the conference. A minimum of corrections and additions were a posteriori introduced, in order to make the text readable. But no attempt was made to "soften" the comments. Such a report should , in no case, be considered as exhaustive, neither reflecting any consensus. It is nothing more than a set of subjective impressions collected by the author, along the nine previous technical sessions, after having read the corresponding reports (references 1 to 9).

In the paper cooling loads are calculated and analysed under different distribution percentages of radiant heat sent out by indoor heat sources to the envelope of an upward displacement ventilation room with different constructions. It is found that the former approximate methods of distribution percentage will cause big errors when accurately calculating the cooling loads formed by radiant heat gains from indoor heat sources. The accurate method should be calculating the cooling loads based on the actual distribution percentage to each of the inside surfaces of the room.
