A LEED certified building in Pennsylvania is making ice at night to keep the building cool during balmy summer days.
Last week, New York City experienced several 90 plus degree-days and little relief from the heat. High temperature days are hitting states across the US and pushing local energy grids to work over-time, which means more expense for consumers and greater impact on the environment. But some companies are designing buildings to combat hot summer days more efficiently.
Completed in 2009 and touted as Pennsylvania’s largest LEED Platinum building, SAP’s 200,000 square foot US headquarters has found a way to lower costs while relieving pressure on the local grid.
Located in Newton Square, PA, the building has 16 huge cooling tanks tucked away in the basement making 3,000 tons of ice during off-peak hours. Rather than running air conditioning during the day and adding strain to the electrical grid, the melting ice chills air in the ventilation system, reducing electrical costs up to 35 percent.
Not only is this building conserving energy through passive cooling - radiant floor heating and cooling, a green roof, rainwater collection and a geothermal heat pump exchanger have all been incorporated into the design.
