This school building HVAC System resulted in complaints regarding Indoor Air Quality and
energy inefficiency. The Local Public Health Department had received complaints and had investigated. The complaints included hot and cold
rooms, poor ventilation and poor IAQ. In addition, the lighting systems needed upgrading. The project objective was to improve the IAQ, comfort,
and overall energy efficiency of the building.

The heating system was converted from steam to hot water boilers. Three 9 million BTU boilers were replaced with seven 2 million BTU hot water
boilers. The domestic hot water was changed from steam to direct fired natural gas. The dishwasher hot water booster was changed from
electricity to gas. Ten pieces of kitchen equipment were changed from electricity to natural gas. Green house changed from propane to natural
