Liaison Reports Don Eppelheimer, Section Head, visited with the group. It was largely developed and funded through DOE, primarily to focus on parasitic transmission losses in ductwork. But the standard does not meet the title purpose and scope as a transmission loss analysis tool to provide pre-construction comparisons relative to transmission losses. Members are urged to follow this standard closely so that this methodology becomes a prominent section of the standard. Changes will also be posted as they are received.
Prompt action is required to facilitate the second public review.
Bjarne Olesen noted that a new European standard was going to be developed to characterize surface radiant heating and cooling. The European standard will cover embedded systems only. Research Brief update by Chapman on RP-1037, incorporation of radiant heating systems that operate at temperatures greater than 300 F into thermal comfort calculations. Brief update by Chapman on RP-1036, which is developing simplified techniques for calculating the heat flux to the occupied space from radiant conduit systems. Motion by Watson to approve as a one-page summary, second by Chapman.
