|With the launch of a new recycling program, university sustainability goals in the new campus master plan and measures to lessen overall environmental impact, TLU goes green.|
New Residence Hall Sustainability Initiatives
|Energy & Atmosphere|
- Designed the building envelope and systems to minimize energy performance, meeting ASHRAE 90.1 and the State Energy Code
- Connected to and utilized the existing campus central plant in lieu of separate HVAC equipment to reduce first cost and lower operating costs.
- Use of Lighting Controls for energy efficiency. This included digital day-lighting controls and photo sensors that automatically dim the interior lighting when natural daylight sufficiently illuminates a space. Additional occupancy sensors automatically turn lights off in unoccupied rooms. All the lighting controls help to further reduce the building’s energy consumption.
- Use of high efficiency motors and variable speed control pumps
- Use of low pressure loss duct systems
- Incorporation of mechanical controls for energy efficiencies and to allow for remote monitoring and control by TLU staff.
- Low water-use native and adapted plants species chosen for landscaping and use of drip irrigation reduce water use for landscaping by over 50%.
- Well water irrigation.
- Utilized Low-Flow toilets and urinals for water conservation.
|Materials & Resources|
- Use of recycled fly ash in concrete production
- Use of low-e reflective glazing
- Construction incorporated waste management to recycle waste materials
- Designated area for recyclable collection
- Use of regional materials including brick, cast stone & concrete, drywall, cold formed metal framing, metal roof panels.
- Use of materials with recycled content, most notably: steel, cold formed metal framing, gypsum board, aluminum storefronts and windows, carpet, rubber flooring, toilet partitions, ceramic tile, metal roofing panels.
|Indoor Environmental Quality|
- Compliance with ASHRAE 62 code for acceptable indoor air quality requirements
- Designed HVAC systems with carbon dioxide monitoring sensors for densely occupied areas.
- Designed the HVAC systems and building envelope to optimize air change effectiveness
- Specified Low-Emitting Materials for sealants, adhesives, paint and carpet.
- Complied with ASHRAE 55 code providing thermally comfortable environments that support the productivity and well being of building occupants
- Provided for the building occupants a connection between outdoor spaces and the outdoors through the introduction of daylight and views into regularly occupied areas of the building
- Polished/stained concrete floors in public spaces for better indoor air quality.
- Controlled erosion and sedimentation to reduce negative impacts on water and air quality
- Selected a site that did not include sensitive environmental elements and designed a building footprint with stacked floors to minimize site impact
- Minimized parking opportunities by use of adjacent surface parking
- Conserved existing trees reducing the site disturbance
- Limited disruption and pollution of natural water flows by managing storm water runoff.
- Primary orientation of the building east-west (less surface exposure to rising and setting sun, thus lowering energy consumption and cost)
TLU sustainability invests time and talent into making our world a better place
|Donate Books, Plant Trees|
At the end of each semester, TLU students donate books, via the TLU Bookstore, that have little or no market value to an organization called Book Drives, Inc. Book Drives recycles the books and contributes money to Trees for the Future, which plants trees based on the numbers of books recycled.
|Saving the Environment One Recyclable at a Time|
On April 12, 2011, Greenstar Recycling
of San Antonio brought its educational trailer to the TLU campus to help kick off the new recycling program. TLU partnered with Greenstar Recycling to outfit classrooms with paper bins and 90 gallon purple toters in key locations to collect paper, plastics and aluminum.
|Small Actions with Big Impacts|
TLU is currently working on several initiatives to better serve the environment.
