SS1.1 Environmentally Sensitive Land

West Contra Costa Unified School District had LFR Inc. prepare a Phase 1 Environmental Site Assessment for Ford Elementary School. This document is dated February 28, 2007 and has a reference number 003-09251-00. Within Appendix B there is a detail map – 01799060.2r that indicates the site is outside of any 100 year flood zone.

SS1.3 Central Location

The West Contra Costa Unified School District attendance map for Ford ES indicates 90% of the students live within ½ mile of the school site.

                        

SS1.4 Joint Use Facilities

Ford Elementary School is designed for after hour use of the community, providing limited access to the Library and Multipurpose rooms. Each area also includes public restrooms. The separation of the Library from the rest of the school is created by the release of the magnetic hold open doors, A100,2 and A136,1.This allows access to the Library (room A119), Lobby (A118) and Rest Room (A112) through a proximity lock located on the front door (A118). Zoned alarm systems allow this area to be off while the other zones are alarmed. The multipurpose room is separated from the rest of the school by magnetic hold open door C100,1 and has a zoned alarm as well. This allows access to all of area C excluding rooms C114 & C116 as well as the playground through door C100,2.

                       

SS3.1 Limit Storm Water Runoff

The addition of pervious areas reduces the site imperviousness by 38% from its present state. Runoff from the roofs is directed to vegetated swales that absorb and retain the rain water.

                        

SS3.2 Treat Storm Water Runoff

98.83% of the storm water is treated onsite. This integrated system utilizes; 1 small Bio-Retention area, 2 Vegetated Swales, 4 Flow-through Planters and 4 Infiltration Planters. Being a site less than 3 acres, the design incorporates a decentralized but integrated format that requires distinguishing between already treated storm water and untreated storm water.

                        

WE1.0 Create Water Use Budget

Attached is the CHPS worksheet indicating 424,000 gallons per year for the school landscape.

                        

WE2.1 Reduce Sewage Conveyance

Through the use of low flow toilets and urinals the sewage conveyance was reduced 48.54%.

                        

WE2.2 Reduce Indoor Potable Water

Through the use of low flow plumbing fixtures the indoor potable water was reduced 40.24%

                       

EE1.0 Minimum Energy Performance

Title 24 Energy calculations indicate Ford ES exceeds the required 10% reduction.

                       

EE1.1 Superior Energy Performance

CA title 24 Energy Calculations indicates 27% better than required performance.

                        

EE3.0 Fundamental Building System Testing

The District has hired WSC ca, a commissioning agent.

                       

EE3.1 Enhanced Commissioning

WSC Ca will perform an enhanced commissioning per attached specification section.

ME1.0 Recyclables Storage and Collection

There is a place for recycling bins in every classroom. Every floor has collection areas and there is an outdoor fenced area for storage of the Local collection agency’s bins.

ME2.0 Construction Waste Management

75% of construction waste during construction will be diverted to recycling streams.

ME2.1 Construction Site Waste Management

75% of the non hazardous construction waste during increment 1 (demo and pad prep) was diverted to recycling streams

EQ1.1 Day Lighting

Exterior sun shade devices prevent direct sun from touching the work surfaces during the prescribed time frames.Day lighting analysis was first performed during schematic design using the SPOT program. It was later modeled during design development at the Pacific Energy Center’s Sky Box. Finally, it was modeled during construction documents to reconfirm the final configuration of the building.

EQ1.3 Electric Lighting

Classroom lighting is through the use of the Finelight, direct / indirect lighting system. The teaching wall has a separate light, allowing the teacher multiple ways to use the classroom lighting. Day light sensors control the dimmable ballasts to save on the electrical demands of classroom lighting.

EQ2.2 Low Emitting Materials

EQ3.0 & .1 Improved Acoustical Performance

The wall, floor and roof assemblies were studied by Thomas Schindler of Charles M. Salter Associates for enhanced acoustical mitigation of environmental noise. Within the classroom the ventilation system was designed to minimize the mechanically generated noise. The ceiling has a high rating (NRC .90) for reducing the reverb time of noise generated within the classroom.
