Reports on the effort of the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) to fund a research on lighting heat gain distribution in buildings. Role of lighting in the cooling load of a building according to Christopher Wilkins, research committee chair for the ...
for a particular hour is thesum of the convective portion of the heat gain for that hour plus thetime-delayed portion of radiant heat gains for that hour and the pre-vious 23 h. Table 14 contains recommendations for splitting each ofthe heat gain components into convective and radiant ...
