Building Features and Provisions to Protect and Enhance the Environment

LEED for New Construction version 2.2 has 6 areas of focus:

1. Sustainable Sites

2. Water Efficiency

3. Energy and Atmosphere

4. Materials and Resources

5. Indoor Environmental Quality

6. Innovation and Design Process

 

Point Value Certification

Certified 26 - 32 points

Silver 33 - 38 points

Gold 39 - 51 points

Platinum 52 - 69 points

CTR earned 41 points for a Gold Certification

 

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
