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, long-range 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.

Green Building Policy ImplementationPerformance 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.

Pursue formal LEEDTM certification witha minimum of 33 pointsresulting in a LEEDTM Silver rating, with a goal of LEEDTM

Gold on applicable projects.

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.

14

Economizer Units

Roof-top economizer units will circulatefresh air into the building.

Building exceeds Title 24 requirementsby more than 40%.

15

Window Overhangs

Window Overhangs reducesolar heat gain and cooling loads.

16

Project Recycling

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

17

Sustainable Features

A high percentage of newconstruction materials are madefrom recycled materials:• Countertops = recycled newsprint • Fencing = recycled plastics• Play Surface = recycled tires

18

Solatube Operable Skylight

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

19

Storm Water Design

Miramar College stormwater detention basin.

20

Construction Recycling

Recycling old asphalt on site as base materialfor new parking lot at Miramar College

21

Miramar College

Water-efficient landscapinguses reclaimed water.

22

Solar Initiative

We are looking to install 2 MW of photovoltaic capacity throughPower Purchase Agreements.

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

23

High Performance DesignSun studies can be done for the building or for individual spaces. Daylight, Energy Performance and Acoustic Performance all can be tested in the model.

Building Information Modeling

24

Building Information Modeling

Sustainable DesignBIM 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

25

Geothermal Heat Exchange

Currently evaluating feasibility of using this system inlieu of expanding central plant for 400-ton load of future Learning Resource Center.
