Walmart Canada to open sustainable distribution centre
Cutting-edge facility will be an estimated 60% more energy-efficient than company's traditional refrigerated centres and will test fuel cell technology
The announcement was made at the Walmart
The company expects to open the sustainable distribution centre in the fall of 2010 and is investing
"We've set the ambitious goal of building the most sustainable distribution centre possible, while at the same time delivering a compelling return on investment," said
Some of the distribution centre's sustainability features include:
Hydrogen Fuel Cell Technology
In keeping with its long-term environmental goal, to be supplied 100 per
cent by renewable energy, Walmart Canada will test the use of hydrogen
fuel cells for the first time. Hydrogen fuel cells produce only heat and
water as by-products and will replace traditional lead acid batteries in
the centre's entire material-handling fleet. Fuel cells will increase
productivity and reduce operational costs because they last longer, do
not need to be changed and can be refuelled in three minutes. Hydrogen
will come from Quebec, where the element is produced using 98 per cent
renewable energy sources, particularly hydroelectricity. Powering the
material-handling fleet with fuel cells will reduce greenhouse gas
emissions (GHG) by an estimated 530 tonnes.
Solid-State Lighting
In a first for a refrigerated distribution centre, the entire facility
will be lit exclusively by low-energy solid-state (LED) lighting. LED
lights operate at low temperatures, have long life spans and strike
instantly, providing important operational and environmental benefits in
a refrigerated building. Using LED lights is expected to half the energy
bill for lighting and save an estimated 1,400,000 kilowatt hours annually
or the equivalent of powering 121 average size Canadian households with
power for a year.
Solar and Wind Energy
Walmart Canada plans to test solar and wind energy at the Balzac
facility. Sixteen solar thermal panels, mounted on the side of the
centre, will supply clean, renewable energy to heat hot water for the
facility. A 225-kilowatt wind turbine on-site will produce enough energy
to supply 55 average size Canadian homes with energy.
Energy-Efficiency
Operating a large refrigerated building requires a large amount of
energy. Walmart Canada has carefully evaluated its purchasing decisions,
improved building design and made technology choices to make the facility
more energy-efficient. The company undertook a state-of-the-art infrared
scan of an existing refrigerated distribution centre in Ontario,
identifying areas that could be made more energy-efficient in the new
centre. Key features of the Balzac facility include a leading-edge
refrigeration system requiring significantly less power, high-efficiency
doorways between temperature zones, upgraded seals throughout the
building and a white roof membrane that deflects an estimated 85 per cent
of sunlight to reduce heat gain and demand on the electrical grid.
Sustainable Construction
Environmental sustainability is an important part of the construction
phase, now underway. Through innovative waste diversion strategies,
Walmart Canada expects to divert as much as 50 per cent of its
construction waste from landfill. The entire construction phase will also
be powered by renewable energy through Bullfrog Power, a Canadian
provider of low-impact renewable electricity.
"The Balzac distribution centre is not only about reducing our own environmental footprint and making strides to achieve our long-term sustainability goals, it's about leading change across an industry and the business world at-large," added Ellis. "Our hope is that in the future, facilities like this will no longer be demonstration facilities but the norm for the industry."

FACT SHEET
----------
Balzac Distribution Centre
Facts
- Location: Balzac, Alberta, Canada
- Expected Opening Date: Fall 2010
- Size: 450,000 square feet
- Walmart Investment: $115 million
- Developer: Stuart Olson
- Operator: Centric Retail Logistics will operate the centre once
complete
- Construction is expected to create approximately 1,400 jobs including
800 trade and construction roles
- Centre will employ 600 people once complete
Sustainable Features
- Hydrogen fuel cells in entire material-handling fleet
- Use of solar and wind energies
- Use of low-energy solid-state (LED) lighting exclusively
- High-efficiency doorways between temperature zones to minimize heat
transfer
- Insulated and windowless docking doors
- Insulated docking plates with upgraded seals
- A white roof membrane to deflect sunlight by an estimated 85 per cent
and reduce heat gain and demand on the electrical grid during the
summer
- Increased insulation in the roof to reduce energy loss
- Solartubes(TM) on the roof of the building over office spaces take
advantage of natural light and reflect it into interior spaces,
reducing the need for artificial light
- Leading-edge refrigeration system reduces energy needs and uses
ammonia instead of more harmful refrigerants
- Waste heat from refrigeration system heats building during winter
months
- Chemical-free water treatment process in refrigeration system
- Concrete floors using fly ash reduce the use of cement and replace
chemical-intensive tiling throughout the centre. A by-product of coal
burning at electric utility plants, the use of one tonne of fly ash
saves the equivalent of one barrel of oil.
- Use of low-VOC (volatile organic compound) paint and materials
- Low-flow sinks, toilets and urinals in washrooms
- Native plant landscaping to replace traditional manicured lawns
- A sedimentation pond, adjacent to the centre, collects storm water
and allows sediment, which can affect water quality, to settle before
water is returned to local water systems
