Engineering Services Building Highlights
Renewable, Recycled and Recyclable Materials used in the building
Existing asphalt was pulverized and used as part of the base. Recycled tire rubber was used in the fabrication of roof tiles. The gypsum wallboards contain 90% certified recycled content. The ceiling panels contain a minimum 66% recycled materials. Resilient flooring, which is a homogeneous sheet linoleum consisting of sustainable materials such as, linseed oil, cork, wood flour, and rosin binders is mixed and calendared onto natural jute backing. The carpet contains 100% post-consumer recycled content made from PVC carpet backing and the nylon fibers of used carpets and carpet tiles. The wall corner guards are made of 100% post-industrial recycled high-density polyethylene and FSC certified wood. The doors contain up to 77% FSC certified wood. Fabric for wall divisions is made of corn fibers, a 100% renewable and compostable material. The chairs have an average 32% recycled content, and are at least 96% recyclable. The Ethospace® System is up to 78% recyclable and has 35% recycled content. Finally, work surface substrates are composed of more than 90% pre-consumer recycled wood content certified in accordance with Scientific Certification Systems.
Storm Water Management
The Engineering Services Building features an innovative storm water management system designed to serve as a laboratory for water quality improvement. It includes both and extensive and an intensive green roof, a rain garden and a Baysaver unit. The green roofs cover 87% of the roof surface and are designed to absorb 75% of annual rainfall, with the remaining runoff going into a rain garden, where its absorbed by native plants. Runoff from the parking lot flows into a Baysaver System that removes pollutants and particles and directs the treated water to an underground storage tank for use in the Vactor (sanitary sewer cleaning) trucks.
Green roofs absorb and filter rainwater reducing the amount of runoff delivered to the storm collection system and improving its quality. The plants protect the roof surface from heat, UV radiation and physical abuse, resulting in a longer lasting roof. Environmental benefits include reduction of heat island effect by cooling air temperatures, reduction of smog and purification of the air by releasing oxygen into the environment and increased insulation from extreme temperatures keeping the building cooler during the summer and reducing use of coolants.
Exterior lights are regulated with photocell controls and interior lighting is primarily indirect with dimming ballast and photometric controls, allowing artificial lighting to respond to the amount of daylight in work areas. The combined use of light shelves and light shades minimizes heat gain through direct sunlight and maximizes use of daylight. Private offices, bathrooms and locker rooms have occupancy sensors to control lighting.
The Environmental Protection Agency (EPA) determined that improving indoor air quality increases the productivity of workers. The design of the Engineering Services Building followed LEED standards for Indoor Environmental Air Quality. VOC emissions were reduced to a minimum by requiring low or inexistent amounts in all paints, adhesives, carpeting, upholstery, manufactured wood products and cleaning agents. The products used in the building followed limits set by the South Coast Air Quality Management District (SCAQMD) and the Green Seal Standard for Commercial Adhesives and Paints. The carpet used also had a high content of recycled material, and the linoleum floors used in most of the building comes from 100% renewable materials, was installed with no VOC containing adhesives and is cleaned with green products.
