Glumac, part of the Tetra Tech High Performance Buildings Group, provided mechanical, electrical, and plumbing (MEP), energy analysis, lighting design, and fire protection services for the Clifford L. Allenby Building.
Challenge
The State of California continues its mandate to decarbonize its government building stock.
Solution
The Clifford L. Allenby Building is targeting net zero energy, utilizing solar energy through Sacramento’s Municipal Utility District SolarShare program. It also features underfloor air distribution, radiant chilled ceilings, and hot water heat-recovery.
Benefits
The building is expected to use 68 percent less water than a similarly sized office building due to its design of low flow fixtures, 70,000 gallons (about 264,978.7 liters) per year of greywater production, 170,000 gallons (about 643,519.7 liters) of rainwater reuse, and 170,000 gallons (about 643,519.7 liters) of condensate recovery reuse. The building is designed to operate at an energy use intensity (EUI) of less than 25 kilo-British thermal units per square foot (kBTU/sf) per year with a high-performance envelope and the use of radiant heating and cooling systems, a water-source heat pump for heating hot water and domestic hot water (DHW), demand-controlled ventilation, energy recovery in the air handling units, and high efficiency LED lighting.
The Clifford L. Allenby Building achieved LEED Platinum and US Resiliency Council Platinum ratings and was selected as Design Build Institute of America 2022 Project of the Year.
