Tesco to build zero-carbon store
New York City Tesco, the largest retailer in the United Kingdom, announced that it will build the world’s first “zero-carbon” store, in Ramsey, Cambridge, later this year. The store, which is being designed from the ground up to incorporate the latest in green technology, will have a combined heat and power (CHP) plant that will generate enough energy for the store and sell surplus to the country’s National Grid.
According to various reports, the new store will be built with construction materials that have high levels of insulation and the potential to be recycled. Extensive glazing will reduce the need for artificial light, while wind catchers on the roof will help circulate fresh air. It will also have sensor-controlled, energy-efficient lighting.
In related news, Tesco said it has achieved a 0.7% reduction in its absolute carbon footprint. The measurements are based on a comparison of 2008/2009 emissions with an average of emissions in 2006/2007 and 2007/2008. It noted that the reductions were made despite Tesco’s acquisition of a 24-store garden chain during the measurement period.??
Tesco has set three targets for reducing CO2 emissions across its business operations. Each involves cutting emissions by 50% compared against a 2006 baseline.
Existing buildings (those constructed before 2006) by 2020; Distribution of each case of goods delivered by 2012; New stores (compared to comparably sized stores built in 2006) by 2020.
Starbucks installing water-saving faucets
New York City Starbucks Corp. is installing new water faucets that will allow the company to save about 150 gallons of water a day — roughly two bathtubs’ worth — at each of its stores, the Associated Press reported.
The company said it will no longer run water continuously out of its taps to wash spoons and will instead install new faucets that meter out water. Starbucks’ baristas press the faucet once and high-pressure water sprays out long enough to rinse a spoon.
The faucets are now being installed in all U.S. stores and will be delivered to select international locations in the fall. About 600 stores, mainly in California, now have the new faucets.
Stores that do not receive the new metered faucets will use a “single spoon, single pitcher” procedure, which involves using a spoon once and setting it aside to be cleaned and sanitized when dishes are washed.
“These standards balance Starbucks’ need to reduce our environmental footprint and to meet the most stringent health safety standards for customer safety, with minimal cost and operational impact,” the company said in documents obtained by the Associated Press,
The change in policy comes after the company was criticized by environmental groups for wasting water by keeping the tap turned on all day.
Wal-Mart releases results from Ark. energy audit
Little Rock, Ark. Wal-Mart Stores announced today the results of an energy audit of capitol complexes in Arkansas. The report includes recommendations that could save the state more than $430,000 in energy costs and help avoid producing more than 2,800 tons of carbon dioxide annually.
“Wal-Mart’s audit gives us detailed guidance toward reducing the State of Arkansas’s energy costs,” Governor Mike Beebe said. “We appreciate Wal-Mart’s continued commitment to improving its home state.”
During a two-day auditing process, Wal-Mart sent a team of engineering experts to survey state capitol facilities. The team worked with staff from the Arkansas Building Authority, the Office of Energy, the Secretary of State’s office and the Governor’s office. The audit suggests energy-efficiency improvements based on technologies Wal-Mart has successfully deployed in many stores, clubs and other facilities around the world.
The areas covered by the audit include lighting, heating, ventilation and air-conditioning systems, refrigeration and other equipment, technologies such as programmable thermostats and building structure, including insulation and windows.
“Wal-Mart is committed to sharing its sustainability findings and providing governments and businesses with proven energy solutions that benefit the environment and save money,” said Kim Saylors-Laster, VP energy at Wal-Mart. “It’s evident Arkansas has made many improvements to increase building efficiency. We believe the state can recognize even more energy savings and reduce emissions by implementing the recommendations in our audit.”
