The end result of that effort was the first LEED-CI (Commercial Interiors) Certified city hall in Northern California and possibly statewide.
A one-stop counter was installed that streamlines processes such as getting building permits or passports. Additional features include meeting and conference rooms, city council chambers and large community meeting rooms. All totaled, the project earned 24 LEED credits covering everything from building systems to educational signage.
- A new white, single-ply roof was installed directly over the top of the existing built-up roof, lessening the need for cooling in the summer.
- More than 43 percent water savings were achieved due to the selection of water-conserving plumbing fixtures.
- More than 77 percent of the construction waste generated from this site was recycled. That included more than 30 tons of existing materials that were removed and donated to Habitat for Humanity, while the existing HVAC units were removed and 98 percent of them were recycled.
- More than 53 percent of shading was achieved by keeping the existing trees.
- All of the materials used were low emitting.
- The city has permanently installed building signage to point out various green aspects of the building. In addition, a building tour script has been written that includes details on the green aspects of the building and materials used in its construction. In partnership with the Sacramento Municipal Utility District, the city set up an energy efficiency information display in the main lobby of the permit and business development area.
Serving as construction manager, with the subcontracts held directly by the city, DPR kept the project on track despite myriad challenges along the way. Recycling and donating materials from the demolition also proved challenging, as did the management of the cumbersome LEED certification paperwork, which required multiple parties involved to maintain documentation of the products and processes used.
