~ ~, Marion Count Facilities ~ ~ Plan The apartmem's side is heated by original steam radiators with individual hand valve controls. Appro~rimatdy 60 percent of the office areas on the second, third and fourth floor aze heated by steam radiators which are controlled by either hand valve controls or "thennostatic" valve control, both of which aze inefficient. The remaining 40 percent of the offices on these floors are heated by hot water convection radiators which run the length of the east and west walls of these areas. There is only one control valve for each length of radiator which gives very unsatisfactory control as the radiators pass through individual, private offices on each floor along with computer rooms and open office areas, The first floor is a mixture of all the above systems along with gas fired heat pwnp which serves the fIousing Authority offices in the Northeast comer of the floor. The District Attome}~s offices in the Northeast corner of the floor are heated by a gas fired air handler.' The stores/copy room area of the first floor is heated by rivo split unit electric heat pumps which are in the air conditioning mode most of the time because of the heat radi~ted into the area from the boiler room below. The basement has no direcc heating system There is no air conditioning in the apartments. ~ Air conditioning is provide to the office sections of the second, third, and fourth floor from three roof top units which are about 20 yeazs old. These units often develop refi-igerant leaks which require considerable work to repair as the leaks often occur in hard to reach azeas of the equipment. The basement conference room and the Marpo Credit Union are air conditioned by stand alone units for those azeas. The cooling tower for the Ma~po units needs to be replaced as it is developing leaks and is very inefficient. The Purchasing/Mail room is air conditioned by residential, window mount style air condirioners. Page 71
