“…A.6). These estimates differ greatly from those used in Heidelberg for what is believed to be the same measure (Broders and McConnell 1991).…”

“…4) of 102,400 MBtu, or about 9%. This percentage could be contrasted with the 27% space heat savings determined by Heidelberg (Broders and McConnell 1991). The reasons for this large difference in savings are related to the following:…”

“…Heidelberg estimates that their leak detection reduces water consumption by 2% (Broders and McConnell 1991). The DHW circulation pumps keep the water at individual taps hot, eliminating the necessity of draining the cool standing water whenever hot water is desired.…”

“…No data are available regarding the actual annual peak reductions that have occurred. Heidelberg (Broders and McConnell 1991) reports an 8.63% peak reduction, certainly within the capability of Baumholder's 12%. If Heidelberg's factor is applied to Baumholder's 1990 peak, a demand reduction of 600 kW results.…”

“…Estimates of energy savings resulting from operation of day/night setback and optimum start/stop applications vary widely, particularly in new of the diversity in setback temperatures and number of unoccupied hours/week assumed. Heidelberg assumes a 16% savings in.family housing and a 27% savings in administrative spaces utilizing optimum start/stop (Broders and McConnell 1991). Other sources would suggest less potential savings, ranging from 3 to 8% in housing and 11 to 19% for administrative spaces (NBSIR 1984, "Good News..." 1991, NCEL 1982.…”
