Sustainable Building Strategies:


Sustainability on this project has included the siting of the new facility within one hundred feet of a Light Rail Park and Ride Station. This required a Joint Development Agreement with Sacramento Regional Transit (RT) to maximize the use of the existing Butterfield Light Rail Station. That coupled with programs designed to encourage other alternative means of transportation should reduce the number of single occupancy trips to and from the site. This program includes 300 bicycle lockers, shower and change facilities in the office building, extensive pedestrian walkways and preferred parking for car/vanpools.

Resource Efficiency

An overall project anticipated diversion rate for Construction and Demolition Waste Recycling is 75 percent. Current design calls for the reuse of demolished asphalt and concrete as sub-base in the parking lot areas of the project. Reuse of this material, otherwise considered “demolition waste,” is expected to divert approximately 2000 tons of material from the landfill. Existing oak and walnut trees and shrubs that were not preserved, have been chipped and will be used as a mulch in the landscaping and parking lot on site.

Within the building, care is being taken to select building materials that both contain low volatile organic compounds (VOCs) and recycled content and are sustainable in terms of cleaning, maintenance, ability to be recycled and life cycle cost.

Water Quality Control

Another interesting feature of the project is the incorporation of bio-swales in the parking lot to control water quality in storm water runoff. Bio-swales are a Best Available Control Technology (BACT) approved by the State Water Resources Control board for improving water quality from storm water runoff.

Energy Efficiency

The project team has been challenged to exceed the 1998 Title 24 Standard by over 20 percent. In fact, the current design exceeds this requirement by more than 20 percent. Several strategies have been included in the project design to maximize the efficiency of the building envelope which had a major impact on the ability of the project to exceed Title 24 Standards. The exterior of the building will include fixed sunscreens at all east, west and south facing windows. These screens have been designed using a computer model to allow for the maximum amount of natural light and visibility while reducing the thermal energy reaching the windows and will directly save a lot of air conditioning energy. The sunscreens coupled with low e glass and an energy star rated roof will provide a very efficient building envelope.

Additional strategies to achieve a reduction in energy consumption include such items as a central heating and cooling plant with energy management system, variable frequency drives, T5 lamps with dimmable ballast, addressable controls and perimeter lighting with photo-cell control.

The existing Building 2 has been funded to receive photovoltaics. It is expected to produce 469 kilowatts peak (kWp). The project team is still searching for funding to install photovoltaics on the Building 3/Town Center.

Post Occupancy Evaluation

The project plan calls for Post Occupancy Evaluation (POE) to validate design assumptions and performance.

Undecided Sustainable Design Strategies:

The design of the facility will accept both photo-voltaic panels and thermal energy storage strategies if funding for them becomes available at a later date.
