Presentation Transcript

  1. LEED/ Sustainability Highlights • Minimum LEED Silver Certification • Energy efficiency • ~17% more efficient than ASHRAE 90.1 • With Cogen, ~26% more efficient ASHRAE 90.1 • ~45% water savings • 75% of waste will be diverted from the landfill • Existing building reuse

  2. LEED/ Sustainability Strategies • Promoting Alternative Transportation • Preferred parking for Low Emitting and Fuel Efficient Vehicles • Bike storage and showering facilities provided

  3. LEED/ Sustainability Strategies • Energy and Water Efficiency • Active Chilled Beams • Very efficient (low temp) heating and cooling • Enthalpy wheel • Heat recovery from exhaust air • Occupancy sensors and daylight sensors • Reduce excessive use of electricity • Dual Flush toilets and low flow fixtures. • Central Plant Cogeneration System • Combined heat and power greatly improves building’s overall energy usage

  4. LEED/ Sustainability Strategies • Sustainable & Healthy Materials • Recycled materials: cotton batt insulation, carpet tiles, • Rapidly renewable materials (bamboo flooring) • Certified Wood from Sustainably Managed Forests • Reuse of existing walls and finishes (wood trim, doors) • Interior finishes such as paints, coatings, adhesives, sealants, and carpets are low off-gassing materials. • Green roof – planted roofs at flat roof areas.

  5. LEED/ Sustainability Strategies Chilled beams Cotton batt acoustical insulation Daylight dimming controls FSC Certified Wood Doors Triple pane windows Recycled content carpet tiles

  6. CoGen • 16 Cylinder reciprocating natural gas fired engine and generator located in the Central Power Plant. • CoGen supplies 85% of Wesleyan’s annual electric usage. • CoGen supplies 25% of the total campus thermal usage. • The water that cools the engine is used for hot water and heating in High Rise. • The exhaust gas from the engine produces 3,500 pounds/hour steam that goes to heat the campus. • CoGen generates electricity at 80% efficiency, utilities generate and distribute electricity at 30% efficiency.
