San Diego looks at green city hall designs

This is the first in a series of guest posts by different representatives of the Northwest Building Efficiency Center. This post was written by Vicki Zarrel. 

It will be interesting to watch as San Diego picks from competing designs for a new city hall in downtown San Diego. Last week, two designs were revealed, each with goals for achieving LEED ratings.

Developer Gerding Edlen of Portland presented the most ambitious 080723bldggerding280.jpgproposal. The tall, curved structure (at left) would be surrounded by about 2 million square feet of private development. On-site wind and solar panels would generate energy for the entire complex, and an onsite wastewater treatment and reclamation system would bring about a net-zero water system. The Gerding Edlen proposal is designed to meet or exceed LEED platinum standards.

The other development proposal, by Houston-based Hines Corp., is designed to qualify for LEED gold. Hines is proposing a four-story glass city hall with a 19-story office 080723bldghines280.jpgbuilding across the street (below). Hines calls the design “the most viable, cost-saving and low risk proposal.” A company press release gives no specifics on the proposal’s energy or water-saving measures.
