Designing for a Net Zero Future in California

Slide

Our work with California's Department of General Services has provided several lessons learned in the approaches necessary to delivering a sustainable future.

Change Agent

Sacramento's new Clifford L. Allenby Building lays the foundation for a net zero future in California. Home to the California Health and Human Services Agency, Department of State Hospitals, and Department of Developmental Services, this new high performance office space uses a focus on occupant-wellness to approach net zero energy.

A blend of passive mechanical designs, off-site energy generation, and water recycling systems all contribute to the Clifford L. Allenby Building qualify for LEED Platinum and Fitwel certifications, as well as U.S. Resiliency Council Platinum certification.

Sustainability at Work

Rainwater Harvesting
The Clifford L. Allenby Building is designed to use 60 percent less water than similarly-sized office building. It's plumbing design features a significant rainwater harvesting system that supplies nonportable functions like toilet flushing.

Radiant Chilled Beams
Cold water is pushed through radiant piping and the resulting heavy cool air falls to condition the space on hot days without irritating or overcooling occupants with forced air.

Underfloor Air Distribution
Efficiently moves conditioned warm air through the area by utilizing the occupant as the primary heat conductor in the space. This is more energy efficient method of heating a space, and results in improved occupant comfort.

Shared Infrastructure

The Clifford L. Allenby Building is part of the State of California Department of General Services (DGS) Urban District. Three Buildings share a central utility plant, minimizing energy use while reducing embodied and operational carbon emissions. Glumac has used this method to reduce energy costs on prevous projects, including the Brewery Blocks and Twelve West building in Portland, Oregon.

District-Scale Thinking.

The Clifford L. Allenby Building shares a central utility plant with the nearby Capitol Annex Building and the net zero energy Natural Resources Headquarters. Shared infrastructure presents significant energy and carbon savings and demonstrate the benefit of district-scale design.
