Mechanical and plumbing design (joint venture with BR+A) for the IQHQ Research & Development District, which is located over three city blocks along the San Diego bay. The project includes various mid-rise structures (lab, office, and retail spaces) and one 17-story tower, a museum, and approximately 3 acres of green space and rooftop decks. This project is the largest urban commercial waterfront site in California’s Pacific Coast.
Mechanical systems include extensive Life Cycle analysis comparing various options for the central plant, as well as air systems including all electric chillers, primary pumping system, variable air volume AHU, and fan coil unit air system.
The selected system is all variable pumping with two electric chillers in parallel, and variable condenser water flow system. The air system consists of a custom-made fan wall technology air handling unit system. The entire HVAC system is monitored and optimized via state-of-the-art Energy Management Control System (EMCS).
Plumbing systems consist of general plumbing, high efficiency gas-fired water heaters and low flow fixtures. It is also designed to accommodate future laboratory process piping systems. Sanitary waste and vent are provided to restrooms, showers and sinks.
