A 12,000 sf maintenance facility in Connecticut has been retrofitted with a 1,500 sf passive-solar Trombe wall, 2-1/2 in. of foam roof insulation and a new control system that allows night/weekend temperature setback. Also a new separate boiler has been installed to heat an office/locker wing of the facility. An energy-consumption monitoring system was installed in January 1980 and has collected data for 1-1/2 yr. before the retrofit and two years after the retrofit. Actual energy consumption was very close to that predicted using simple analytical methods. Average oil consumption for the period 1973 to 1980 was 8206 gal/yr. After the solar wall was installed and other energy-conservation measures implemented yearly oil consumption dropped to 2744 gal. and 2120 gal. for the 81/82 and 82/83 heating seasons, respectively. A number of energy-conservation recommendations are presented in this report, including but not limited to the following cost-effective measures that should be applied at other ConnDOT facilities: 1. Identify facilities with oversized boilers and reduce burner-firing rates; 2. install modern, more efficient thermostatic control systems with night and weekend setbacks to reduce the average builing temperatures; 3. increase roof and wall insulation and install storm windows; and, 4. replace inefficient lighting fixtures with more economical ones.
