The Energy is Greener in the East Library Side

The east Green Library energy system has been updated through the Return Temperature Optimization Program (RTOP). This historical building utilized old-fashioned, pneumatic-controlled heating and cooling valves, and these were replaced with sustainable, pressure-independent electric control valves. Pressure-dependent systems lead to both excessive and insufficient space conditioning, given that the incoming pressure varies. Using pressure-independent valves in this renovation saves energy and increases thermal efficiency for hot and chilled water distribution to and from the Central Energy Facility.
