This
residential project includes 380 apartments and incorporates
numerous sustainable design features including: dedicated
fresh air supplied to every residence, with air filtration
to remove 85% of particulate matter; central humidification
system to maintain a minimum 30% relative humidity during
the heating season; use of building materials and finishes
free of harmful off-gassing and low in VOCs; ongoing
air quality testing after completion; water recycling
system to treat and reuse building waste water supply
toilets and cooling towers (recycled water used for
make-up); storm water collection and reuse for drip
irrigation systems; central water filtration system;
use of materials containing high recycled content, wood
materials from certified forests, and/or use of materials
from rapidly renewable natural resources; a large percentage
of building materials originating from within 500 miles
of the building site; highly insulating and air-tight
exterior wall system; spectrally selective, low-e glass,
which reduces solar heat gain while retaining a high
visible transmittance (Viracon VE-1-2M U=0.29, SC=0.43,
VT=70%).; air-tight casement windows; “Green”
planted roofs; high efficiency lighting throughout the
common areas of the building; occupancy sensor-controlled
public area lighting, including stairs, corridors, storage
rooms, offices, public toilets and garage; daylight
dimming system in the public lobby; high-efficiency
fluorescent lighting in apartments where appropriate
(entries, bathrooms, kitchens); master switch to turn
off switched-lighting in the entire apartment except
bathrooms; Building Management System (BMS), including
wetbulb temperature reset for cooling tower; programmable
thermostats to control all apartment heating and air
conditioning; gas-fired double effect, absorption chiller
heater with COP = 1.0 and IPLV = 1.19; condensing boiler
for domestic hot water, with high combustion efficiency;
variable speed drives on the secondary water pumps,
and on cooling tower fans; exhaust fan modulation in
garage based on CO sensors; premium high efficiency
motors; ENERGY STAR-labeled appliances throughout the
building; photovoltaic panels that generate 5% of peak
electricity for the core-and-shell building; fully commissioned
systems to ensure intended performance.
This project is considered
to be the first high-rise residential building in America
to obtain a LEED Gold Rating from the US Green Building
Council.
