NYC housing
    • PASSIVE SYSTEMS• Exterior Wall: DOE 2 modeling• High R values• Low air infiltration• Windows: AW 70, minimize air infiltration• Glazing: low – E, Min. 75% VT, U .30 (less solar heat gain)• Roof: R30 min, planted roofing system• Local Resources: 500 mile radius• Materials Selection: recycled (steel and concrete), post- industrial and rapid renewable (bamboo flooring)• Low VOC Materials (carpet & paint)• Improved Indoor Air Quality
    • ACTIVE SYSTEMS• Heating and Cooling: open loop standing column geothermal exchange (design concept: 20 wells, 700 tons)• Photovoltaics: 25-30 KW• Heat Recover• IAQ: Fresh air filtered & conditioned (3x normal air exchange)• High Efficiency: Energy Star Fixtures, Heat Pumps, Condensing Boilers• Motion Detector Light Fixtures• Digital Sub-metering: programmable thermostats
    • BUILDING ENVELOPE DESIGN• Reduced thermal bridging in walls• Cardinal Low-E2-170 glass with U-0.29 (center of glass), shading coefficient 0.43 .37 solar heat gain coefficient• 70% visible transmittance or glass with equivalent properties in terms of U-factor & shading coefficient• Airtight wall construction & airtight windows (documented field tests).• Planted roofSTRUCTURAL SYSTEM• Steel: 95% recycled content, local• CMU: recycled content, massive (high STC), local• Pre-cast Concrete Plank: recycled content, fast installation, local
    • The financing was designed to protect the interests of long-term Harlemstakeholders by making 50% of the units affordable and 50% market rate (the firsttime in New York City) with a 50% preference for existing Harlem residents.
    • The undulating massing is a creative interpretation of the NewYork City zoning code to provide alternating rhythm of tower andwall along the building’s 300-foot football-field length.
