equipment loads during the cooling season,
lowering electric costs. An intensive integrated investigation of the design of the
HVAC system was performed to optimize
energy and maintenance costs while providing as high a level of indoor air quality as
The building isn’t air-conditioned.
Instead, a pressurization and ventilation
system coupled with fans the size of heli-
lavatories, and a low-flow shower head
helped the project exceed 50 percent water
savings as compared to a baseline calculation.
For lighting systems, energy efficiency
was achieved through T5 fluorescent high-bay lighting in the warehouse and T5 volumetric lighting in the office. The lighting in
all periodically occupied office spaces is
controlled by occupancy sensors with
the environmental impact of transportation,
the project insured that 70 percent of the
materials installed were locally produced
and extracted within a 500 mile radius of the
project site. Furthermore, over 60 percent of
the regionally produced and extracted
materials noted above came from a distance
of 200 miles or less.
The collaborative approach of the project team encouraged “creative problem
copter rotors circulate air in the building
with the result that employees say that it
feels like it is air conditioned, Carron says.
“You can do so much better when it
comes to energy efficiency, water use and
productivity in the facility when you build
green from the outset,” he says.
The use of low-emitting materials such as
interior paints, adhesives, sealants and carpet
were installed to help provide a higher quality of indoor environment for the contractors
and visitors during construction and to maintain this air quality for the duration of building
life. Furthermore, no interior wood products
contain urea-formaldehyde, which further
enhances indoor air quality.
The use of water-conserving toilet fixtures, waterless urinals, half-gallon per-minute aerators on all faucets and
unoccupied times controlled via a schedule
in the lighting control system. Warehouse
aisle lighting was installed with an integral
occupancy sensor so that off-hours use is
automatic and only on when required.
The building’s landscaping does not
require permanent irrigation which eliminates the need for potable water or other natural surface or subsurface water resources
available on or near the project site.
During the design and construction
phase the team worked to select materials
that were locally produced and contained a
high recycled content. Forty percent of the
total products that were installed within the
facility contained recycled content. Of those
materials installed, 12 percent contained
post-consumer content and 34 percent contained pre-consumer products. To reduce
solving,” DiVall says, such as removing
12,130 tons of bottom ash waste from a
local landfill and reusing it in construction.
The project received Leadership in
Energy and Environmental Design (LEED)
Gold certification and other recognition
from the U.S. Green Building Council. In
2007, it won the National Association of
Industrial and Office Properties’ national
Green Development Award, reportedly the
first and only warehouse to be so recognized. Most recently, CoreNet Global recognized the distribution facility with its 2008
Sustainability Leadership Award for Design
