46. Steam Statistics
DeRoy Apartments uses steam for heating, domestic water heating & cooling (steam absorber)
Chatsworth uses steam for heating only (gas domestic water heating; no air conditioning)
Winter MiAPPA Meeting
March , 2005

47. Steam Statistics Current district steam cost is $725,500 annually
Average cost per Mlb = $20.73 (FY04)
Total Sq. Ft. is 552, 300
Average cost per Sq. Ft. is $1.31 (steam only)
