I F�ne 'gy, <br />4 Observations <br />4.1 General <br />The majority of the equipment in place at RCCC South is in relatively good condition. <br />This initial audit covered a sampling of the systems in the building and is intended tc <br />provide an indication of available opportunities to improve the buildings' energy <br />efficiency. It is not intended as a complete study or survey of all building systems. <br />4.2 Building HVAC <br />4.2.1 Building 1000 <br />Building 1000 was originally constructed in 1989 but underwent cosmetic <br />renovations in 2008 when some classrooms were converted to offices. Building <br />automation controls are largely pneumatic with limited DDC. There is one large AHU1 <br />for this building. The supply and return fans have inlet guide vanes (IGV); no VFDs <br />or DDC controls are present on this unit. Thy c watP <br />domestic hot water. There is a 3 -way <br />is leaking and needs to be ar <br />repaired or replaced <br />The boiler is original to the <br />building and is operating in the <br />60% - 80% efficiency range. <br />Hot water is used primarily for <br />reheat. Hot water temperature <br />is not currently reset based on <br />OA temperature. The boiler is <br />supposed to be locked out so <br />that it will not run above 60 <br />degree OA temperature but it is <br />not clear if this is working <br />properly. <br />Classrooms are provided with <br />VAV boxes, which were not <br />observed. <br />AHU1 readings were as follows: <br />• 58 °F CHWS <br />• 60 °F CHWR <br />Rev A 2012 -05 -15 <br />11 <br />Figure 13: AHU in Building 1000 <br />Page 18 <br />Final Draft <br />G -2 <br />Page 342 <br />
