DESCRIPTION
The historic SMUD Headquarters building was renovated with modern design concepts while preserving its iconic historical features. The renovation included replacing the mechanical systems for efficiency and sustainability.
The design of the HVAC system serving the project needed to be energy efficient, but also tuned to optimize the operation of the Central Plant and the associated thermal storage. A HVAC system utilizing Chilled Water Induction Boxes (CWIB) was chosen to serve the perimeter areas of the building. The CWIBs include a secondary chilled water coil that provides additional cooling during peak cooling periods. To provide heating, special 6-way valves switch the water source from chilled water to heating hot water. The resulting lower heating hot water temperature increased the efficiency of the boilers located in the Central Plant. These innovative HVAC measures were integral in achieving SMUD’s energy efficiency and sustainability goals.
The SMUD Headquarters rehabilitation project achieved LEED Gold certification, is on the National Register of Historic Places, and received a CMAA 2020 Project Achievement Award.
