Pressure Sustaining Valves How They Helped Solve Insufficient Plant Static Pressure on Large Campus Loops at Texas A&M

Texas A&M University (TAMU) has implemented numerous energy conservation initiatives on its utility plants and buildings that have achieved $210 million in cost avoidance through increased operating efficiencies since 2002. Two of these plants, TAMU's Central Utility Plant (CUP) and Satellite Utility Plant 3 (SUP3), provide low temperature hot water (LTHW) and chilled water (CHW) to over 230 buildings with over 16 million ft(2) (1,486,448 m(2)) through the hydronic network on main campus (Figure 1).
