Fieldhouse - Green Features

Site

• Tight-knit, pedestrian-friendly campus infill development
• Bike storage and changing rooms provided
• Exceeds local zoning open space requirements
• Storm water design promotes infiltration, captures and treats runoff beyond national standards
• White reflective roof to reduce “heat island” effect
• Significant light pollution reduction with effective selection of interior and exterior lighting fixtures
• Highly-reflective site concrete to reduce heat island effect of site improvements
• Collaborative design on 16,800 sq. ft. with students and faculty, board of trustees, design team, and construction manager
• Students integrated into process throughout design

Water Usage

• No irrigation
• Low-water fixtures and composting toilets minimize water usage

Energy

• Reduced carbon footprint by 100%
• 25-year carbon dioxide reduction of 1,077,516 pounds
• 25-year sulfur dioxide reduction of 4,564 pounds
• 25-year nitrogen oxides reduction of 1,802 pounds
• Projected net-zero energy on yearly basis with 36.8 KW of solar-tracking photovoltaics in field next to building
• Energy usage modified to be approximately 45% of that allowed by Vermont Energy Code
• All lighting on occupancy and daylighting sensors
• All ventilation on occupancy and carbon dioxide sensors
• Air to air heat pump system selected is more efficient than current ground source systems
- Ground source at +/- 2.3 COP (coefficient of performance)
- Air to air heat pump at +/- 2.7 COP
• Heat recovery on building exhaust air
• Automatic natural ventilation (windows on automatic night time flushing)
• Building envelope
Super-insulated envelope with:
- R20 under slab insulation
- R20 foundation wall insulation
- R45 walls
- R 60 roofs
- R5 fiberglass windows (triple insulated, low-e, operable units—U value of 0.19)
- Sky lighting for approximately 40% of floor area
- Detailing to avoid air infiltration and thermal bridging

Materials & Resources

• 20% fly ash in concrete reduces carbon footprint on a pound per pound basis
• Construction waste management with 75% diverted from disposal
• More than 50% of wood Forest Stewardship Council (FSC) certified (sustainably harvested)
• Use of 20% recycle materials such as steel used in steel framing and light-gauge wall framing
• Low or nearly no VOC (volatile organic compound) paints, finishes, and adhesives used throughout project
• Local materials such as site-harvested wood used in public areas
• No chlorofluorocarbons (CFCs)

Indoor Environment Quality

• Natural ventilation, operable windows, and no air conditioning
• Formaldehyde-free composite woods
• Meets ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) indoor air quality standards
• CO2 monitoring for indoor air quality
