CTR LEED Points of Interest:
1. CTR Sustainable Site points
- An erosion and sedimentation control plan was implemented to prevent loss of soil during construction by storm water runoff and wind erosion.
- Public transportation access is provided by bus stops located adjacent to the facility.
- Bicycle use is encouraged by the inclusion of a storage rack outside the building as well as a shower and changing facility within the building.
- A combination of at least 50% of the site landscape and sidewalks use paving materials with a solar reflectance index of at least 29 to limit heat island effect.
- Roofing materials with a solar reflectance index of greater than 78 are used to limit heat island effect.
- The building exterior and interior lighting is designed to reduce sky-glow and glare as well as eliminate light trespass from the building.
2. CTR Water Efficiency
- The landscaping was designed to reduce water consumption by 50%
- The irrigation water used on site is supplied by a non-potable source which is a combination of captured condensation and storm water.
- Interior has high efficiency fixtures to achieve a 42% reduction of potable water use.
3. CTR Energy and Atmosphere
- Prerequisite points include Fundamental Commissioning of the building energy systems, Minimum Energy Performance & Fundamental Refrigerant Management
- CTR achieved 5 points in Optimized Energy Performance
- Enhanced Refrigerant Management
- No CFC based refrigerants are used in this facility. Refrigerants are used that minimize or eliminate the emission of compounds that contribute to ozone depletion and global warming.
- Measurement and Verification control sensors are placed to integrate with the overall building management system for ongoing accountability of building energy consumption over time.
4. CTR Materials and Resources
- Prerequisite points required designated areas for collection of recyclable materials within the facility.
- During the construction phase the contractor implemented salvage and recycle plan for non-hazardous construction waste which included sorting and measurement of construction waste.
- Materials with recycled content were used in the construction process.
- Materials used have been extracted, harvested or recovered as well as manufactured within 500 miles of the project site were used in the construction process.
5. Indoor Environment Quality
- Prerequisite points included The Indoor Air Quality performance requirements of ASHRAE 62.1-2004 Ventilation for Acceptable Air Quality
- Prerequisite included prohibition of Smoking within the facility during construction and occupancy
- Direct outdoor airflow measurement devices are installed to provide feedback on the performance of the ventilation system
- Additional outdoor air ventilation is provided for all occupied spaces.
- An Indoor Air Quality Management Plan was implemented during construction including a full flush-out of the facility with 100% outside air prior to occupancy.
- All adhesives and sealants used on the interior of the building met rigorous requirements of VOC (volatile organic compound) limits.
- All carpet and cushion installed in the facility meet the requirements of the Carpet and Rug Institute Green Label Program.
- No added urea-formaldehyde resins were used in any of the plywood, particleboard, mdf, door cores or other composite wood products in the facility.
- Indoor chemical and pollutant source control is provided.
- All regularly occupied rooms have occupant controlled lighting.
- Comfort controls are provided for a minimum of 50% of the building occupants and all shared-multi-occupant spaces.
- HVAC systems and the building envelope are designed to comply with ASHRAE 55-2004 Thermal Comfort Conditions for Human Occupancy.
- Occupants provided with a visual connection between indoor spaces and the outdoors from 78% of the regularly occupied spaces.
6. CTR Innovation and Design Process
- University and Metro transit access
- Fume hood commissioning including proximity sensors to reduce exhaust speed when no person is adjacent
- Water consumption reduction by 42%
- Project architect, contractor, engineer and LEED administrator are LEED Accredited Professionals
