Transcript Texas Woman’s University

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 Contract
Old 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.
Concurrent Operational Initiatives
• 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.
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 Outdoor
Pool requires
450,000
gallons 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:
Newspaper
Magazines
Junk Mail
Business Papers
School Papers
Catalogs
Mail
As a rule of thumb, AbitibiBowater says,
“If it’s clean, it’s dry, and it tears, it’s probably recyclable.”
Making a Case for Efficiency
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
• Energy Savings
• Carbon output reduction
• Water use reduction
• Cut in waste costs

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.
