Heat Recovery Ventilation Putney Field House Design & Environmental Highlights Design Process William Maclay Architects DEW Construction Corporation;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. 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 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; R60 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
