Green Building Policy  The

Board of Trustees is committed to environmental stewardship as a fundamental operational objective and integral to fulfilling our educational mission.

 The

Board recognizes its fiscal responsibility to use taxpayers' dollars wisely for the best long-term, longrange investment.

 The

goal of this policy is to provide working and learning environments that are:     

Efficient in use of energy, material and water Easy to maintain and operate Thermally, visually and acoustically comfortable and healthy Safe and secure Sited in an environmentally responsible manner.

3

Green Building Policy Implementation Performance Goals Exceed

Title 24 of California Code of Regulations energy efficiency standards by at least 10%.

Ten

percent of the energy utilized by the project must be renewable with at least 5 percent generated on site.

Divert

at least 75% of construction and demolition debris from landfills.

formal LEEDTM certification with a minimum of 33 points resulting in a LEEDTM Silver rating, with a goal of LEEDTM Gold on applicable projects. Pursue

Environmental Sustainability Policy

Environmental sustainability is an essential goal of the District.

Global warming, diminishing resources and escalating costs of energy and rubbish disposal require that management at all levels focus on the efficient and effective use of energy and resources.

West City Campus

9

West City Campus  Brand

new, 39,000 sq. foot, two-story building  Over 50% of project material was obtained locally  Seeking LEEDTM Gold Certification  SDG&E Sustainable Communities Champion  American Society of Civil Engineers Award Winner

10

Detention Basin

Water efficient landscaping and detention basin.

11

Pervious Concrete

12

Waterless Plumbing Low-flow and waterless plumbing fixtures reduce water consumption by over 40 percent, saving an estimated 386,000 gallons of water per year.

13

Economizer Units Roof-top economizer units will circulate fresh air into the building.

Building exceeds Title 24 requirements by more than 40%.

14

Window Overhangs

Window Overhangs reduce solar heat gain and cooling loads.

15

Project Recycling

Sorting and recycling diverted approximately 90% of project construction waste – about 200 tons--from local landfills.

16

Sustainable Features A high percentage of new construction materials are made from recycled materials: • Countertops = recycled newsprint • Fencing = recycled plastics • Play Surface = recycled tires

17

Solatube Operable Skylight

Low E-rated windows and solar tubes to maximize natural daylight.

18

Storm Water Design

Miramar College storm water detention basin.

19

Construction Recycling

Recycling old asphalt on site as base material for new parking lot at Miramar College 20

Miramar College Water-efficient landscaping uses reclaimed water.

21

Solar Initiative We are looking to install 2 MW of photovoltaic capacity through Power Purchase Agreements.

Once on-line, this power will meet approximately 10% of the District’s electrical demand.

22

Building Information Modeling High Performance Design Sun studies can be done for the building or for individual spaces. Daylight, Energy Performance and Acoustic Performance all can be tested in the model.

23

Building Information Modeling Sustainable Design BIM was used to optimize efficiency by making sure that at key times of the year the panels on a classroom building with sloped roofs would not be in the shade

24

Geothermal Heat Exchange Currently evaluating feasibility of using this system in lieu of expanding central plant for 400-ton load of future Learning Resource Center.
