Introba (formerly Integral Group) performed MEP engineering, commissioning, and post-occupancy verification and tracking of the building performance to ensure Net Zero Energy operation for this two-story office building.

Highly efficient systems and the building envelope reduced energy demand by 60% over code baseline while supplying the remaining required power by onsite PV power generation. The building is currently operating at 20 percent Net Positive.

This was the largest project to receive Net Zero Energy certification by the Living Future Institute at the time of accreditation. The building is also LEED Platinum certified. Due in part to its prominence in funding conservation, science, and environmental causes, the foundation has chosen to lead by example by employing replicable building methods, materials, and technologies that can transform the marketplace.

The building operates in a natural ventilation model for half the year. The mechanical systems shut down, and the facility manager instructs occupants to open their windows for fresh air. Some of the facility’s novel features include thermal energy storage, chilled beams, dedicated outside air systems, and circuit-by-circuit power monitoring. The project uses 50 percent less water than baseline and captures and filters rainwater for reuse in landscaping and toilet flushing. The facility also features a green roof.
