Heating / Ventilation / Cooling and Lighting System
The existing heating system before the retrofit started consisted of three 9 million BTU steam boilers. The cooling system used a 7.68 million BTU Chiller. The ventilation system was designed to meet ASHRAE Standard 62-19xx prior to 62-1989, which was about 39.3 ccms/min. of outside air per student. Current standard is at least 118 ccms/min. of outside air per pupil and the recommended standard is at least 157ccms/min. of outside air per student. The lighting system consists of the use of T-12 lights with magnetic ballasts, incandescent lights and mercury vapour lamps.
