Grounded in Green

Facilities Management & Construction has been leading the university into the future

by implementing “green” initiatives for years?

Let us show you how…

Energy Performance ContractOld T-12 fluorescent lamps and magnetic ballasts were replaced with new energy efficient T-8 fluorescent lamps with electronic ballasts.

Incandescent lamps with compact fluorescents.

A campus-wide building automation system was installed.

A new energy-efficient chilled water plant and distribution system.

Low flow water closets, flush valves and faucet aerators to conserve water.

To date, the energy performance contract has saved

$2,539,019/year and reduced greenhouse emissions.

• Converting vehicles to bi-fuel systems (propane and gasoline).

• Retirement of 38 full-sized gasoline vehicles with high CO2 emissions and replacement with electric powered golf carts and smaller off-road vehicles.

– Recycling waste engine oil, oil filters, and anti-freeze.

– Updates to the vehicle fuel station with a new vapor recovery system.

• Selection and use of earth-friendly cleaning solutions.

• Phased planting 260 new trees this fiscal year and 200 more each of the next two years.

• Implementing building envelope restoration projects.

• Using low volatile organic compound (VOC) latex paints.

• Campus exterior lighting system replacement.

Concurrent Operational Initiatives

Cumulative Tons of CO2 Saved

Vehicle Emissions Conserved

TWU has conserved CO2

emissions equivalent to

the removal of 31,550

vehicles from the road.

Conservation of Trees

TWU has saved the equivalent of

42,908 acres of trees by reducing its CO2

emissions

Water Conservation

The TWU OutdoorPool requires

450,000gallons to fill

We have conserved enough water to fill

the Outdoor Pool

315 times!

Recycling Construction Materials

21 old chillers and a few cooling towers were abandoned in place. • Recycled Steel @ 371,760 pounds (185.88 tons) and• Recycled Copper @39,908 pounds (19.954 tons)

TWU contributed to saving approximately:• 232.4 tons of iron ore, • 9.3 tons of coal, and • 3.72 tons of limestone

Saved approximately:• 119,335 kilowatt-hours of electricity generation• 335 barrels of oil• 2,026 million Btu’s of energy, and • 744 cubic yards of landfill space

What to put in the green and yellow recycling receptacles on campus….

The current recycling dumpsters located outside the Physical

Plant Service Center, Golf Course, Bralley, Library and Old Main

buildings belong to AbitibiBowater, a recycling company whose

nearest local facility is in Arlington. The recyclables accepted in

these containers are:

As a rule of thumb, AbitibiBowater says,

“If it’s clean, it’s dry, and it tears, it’s probably recyclable.”

Buildings account for:

• 71% of U.S. electricity consumption

• 50% of greenhouse gas emissions

• 30% of raw materials used

• 12% of water

• 70% of landfill waste

Green buildings’ advantages

• Total energy improvement 25-30%*

• Energy Savings 30%

• Carbon output reduction 35%

• Water use reduction 30-50%

• Cut in waste costs 50-90%

Making a Case for Efficiency

FMC’s Design and Construction Standards

• Environmentally-conscious strategies for energy control and automation systems

• Daylight views via bright, airy, and open atriums or other gathering spaces

• External finishes that increase the thermal coefficients of the buildings

• Indoor Air Quality Construction Management Plan

• Monitoring and regulation of CO2 levels

• Construction Waste Management Plan

• High Performance Low-E Glass Glazing systems

• Exterior Shading devices

• Locally Manufactured Materials

General Scope Comparison of a LEED Perspective Performance Contract

Lighting:

• Changing out inefficient lamps and fixtures

• Lighting controls for scheduling

Water :

• Installing high efficiency water valves and fixtures

• Improving irrigation system and control

• Metering of usage

Mechanical :

• Replace old equipment with high efficiency models

• Install VFD on large motors

• Control and condition outside air

• Improve IEQ (Temp. Humidity & CO2 control)

Controls:

• Install new or upgrade existing for better building control

• Improve Environmental conditions in building

• Use as measurement and verification tool

• Monitor and record utility usage (Electricity, water and gas)

Lighting:

• Consideration for daylight harvesting and views

• IEQ Credit 6.1 and 8.1 -8.4

• Up to 5 points possible

Water :

• Rain water harvesting

• Gray water for irrigation

• Waterless Urinals

• Water Efficiency Credits

• Up to 5 points possible

Mechanical :

• Use non-CFC equipment

• ASHRAE 62.1 compliance for O/A

• High Efficiency filters (MERV-13)

• Improve IEQ (Temp. Humidity & CO2 control)

• Supports Optimize Energy Performance goals

Controls:

• Plays a major role in the LEED M&V process

• Energy Star rating of 67 required now

• Energy & Atmosphere credits (Up to 16 points)

• Indoor Environmental Quality credits (Up to 4 points)

Total possible LEED Credits = 25 points (plus several prerequisites)

The Expected Advantages

• Average decrease in operating costs: 11%

• Average decrease in energy use: 14%

• Actual utility cost savings of 20%-40% for new green, and 20%-30% for renovated green buildings respectively

How You Keep Score is Important

Urban Forestry Management

• Identify tree type, determine the age, and conduct a physical count

– GPS location of trees

• Leadership projects to write grants for tree replacement on campus

– Have a list of volunteers

• As student initiative in SCI 2103 (Environmental Chemistry project) did a survey of every office on campus

House Bill 3693

• Directive to establish a goal to reduce Energy Consumption by 5% a year for 6 years

• Directive to use more Efficient Lighting

• Publicly Reporting of utility usage and progress to rewards mandated energy reduction goals

Commitment

529 University Presidents have signed a pledge to reduce their carbon emissions to zero as quickly as possible.
