WHAT IS SUSTAINABILITY?
“Sustainable development is development that meets the needs of the present without compromising the ability of
future generations to meet their own needs.” (Brundtland Report, United Nations, 1987)
“Community colleges are at the forefront of this growing momentum for action on climate change, sustainability, and
green workforce development.” (National Council for Workforce Education)
WHAT IS SUSTAINABILITY TO COMMUNITY COLLEGES?
“The Moreno Valley College "Green Initiative" is part of a District-wide effort aimed at establishing environmentally sensitive and sustainable practices
across all aspects of our institution. ….with a long-range goal of making our college an example of
environmental responsibility.” (Green Initiative at MVC) Sub-committee 1: "Greening our Campus" Sub-committee 2: "Greening the Curriculum" Sub-committee 3: "Green Outreach" Sub-committee 4: "Resource and Energy Conservation" Sub-committee 5: "Fundraising"
WHAT IS SUSTAINABILITY AT MVC?
WHAT IS SUSTAINABILITY AT MVC?
“We demonstrate integrity and honesty in action and word as stewards for our human, financial, physical, and
environmental resources.”
(Moreno Valley College Integrated Strategic Plan)
WHAT IS SUSTAINABILITY?
Triple Bottom Line
WHAT IS SUSTAINABILITY?
CO e = Carbon Dioxide

greenhouse gas may cause.
WHAT IS SUSTAINABILITY?
EUI = Energy Use
Intensity
A unit of measurement that describes energy use in kBTU per square foot/year

ENERGY USE
BUILDING ENVELOPE
Light Mass walls with deep recessed openings
- Have good thermal mass and sun protection
Glazing Units- tinted glass and Older buildings could benefit from upgrades to dual pane high performance glass
ENERGY USE
BUILDING ENVELOPE
Clay Tile Roofs and flat roof areas
- Sloped roof areas could be upgraded to cool roof tiles
- Older buildings could benefit from cool roof upgrades to flat roof areas mitigate solar radiation
ENERGY
CENTRAL PLANT + ROOFTOP PACKAGED UNITS
Central plant
- Recent replacement of four existing boilers
- installation of one air-cooled chiller, (including pumps, electric connections)
Rooftop packaged units
- Have a 10-15 years life
ENERGY
EXTERIOR LIGHTING
General site illumination levels are good
- Building mounted lighting provides too much illumination and creates source of glare

Design with climate-appropriate plants and hydrozones. In Southern California, utilize vegetation that is native or has drought-tolerant adaptations and group
plants with similar water needs together.
Reduce. Design sites to be less thirsty.
Sunset Climate Zone 18-19
Design irrigation systems to use less water more effectively. 50% of irrigation water is wasted by evaporation or runoff due to overwatering.
• smart irrigation controllers
(permit irrigation to occur when needed, rather than on
a preset schedule and adjust watering regime based on
feedback of local weather and soil moisture)
• rain sensor
(monitor precipitation levels and overrides controller to
prevent watering during in rainy conditions)
• rotating sprinkler nozzles
(apply water more slowly/uniformly, allowing water to
soak in rather than run off)
• low volume, point source delivery
(apply water directly next to plant on the surface or to
the root zone in the ground through drip irrigation or
bubblers)
• master valves and flow sensors
(shut system off in the event of line breakages)
Reduce. Design sites to be less thirsty.
Minimize soil evaporation. Provide ground shading and sufficient mulch to reduce water loss from bare soil surfaces.
Reuse. Design sites to be generators.
‘Types’ of Water Potable water is water of high quality sufficient for consumption as defined by
USEPA Safe Water Drinking Act of 1974 and more stringent state standards.
Reclaimed water is former wastewater that has been treated to acceptable levels
for designated types of reuse.
• Urban Runoff
(dry weather surface flow)
• Stormwater
(wet weather surface flow)
• Graywater
(sinks, showers, dishwasher, washing machine)
• Blackwater
(toilets, urinals, industrial sources)
Replenish. Design sites to be filters and sponges.
Low Impact Development (LID) The goal is to maintain + enhance predevelopment hydrology.
• Start at the source.
• Improve quality.
• Reduce quantity (speed + volume).
• Recharge groundwater.

TRANSPORTATION
Overall Approach
TRANSPORTATION ANALYSIS
• Give students and staff real travel options • Look at pricing as a means to affect travel choices • Resource efficiency
Travel Options Site Analysis
TRANSPORTATION ANALYSIS
• College is regional draw • 70% of students come from Moreno Valley, Riverside, and Perris • Automobile access predominates
Travel Options Site Analysis
TRANSPORTATION ANALYSIS
• 4 RTA Bus Routes Access the College • 1 Bus Route stops within the Campus • Go Pass Program Discontinued in 2013 • 1 bike rack on campus (heavily utilized) • City is currently updating Bicycle Master Plan

TRANSPORTATION ANALYSIS
Resource Efficiency Site Analysis
TRANSPORTATION ANALYSIS
• Anecdotal evidence about intermittent parking problems • Typical to plan for the peak of the peak • Leaves underutilized resources much of the time
HABITAT/LANDSCAPE TYPOLOGY ANALYSIS

PART 3: /SUSTAINABILITY STRATEGIES AND TARGETS
ENERGY USE
How is it used currently? What can be done to enhance efficiency?
Where does the campus want to be 10, 15, 20 years from now in terms of energy use?
WATER USE
Water is cheap, does that make it okay?
What can be done to enhance efficiency?
Are all plumbing fixtures upgraded?
Can we think of the campus mechanical units in a new way
that uses water more responsibly?
WASTE
How is it used currently? Where is waste produced on campus?
Are students involved in recycling? Is composting a possibility?
TRANSPORTATION
How can the campus encourage ridesharing?
How do students get to campus?
How do staff/faculty get to campus?
How can tomorrow’s transportation modes be supported?
CULTURE
How can sustainability become part of student life?
How can the campus/buildings demonstrate sustainability?
How can we empower students to be champions for
sustainability?
