Starving the energy monster for energy efficient buildings
January 19, 2015
There are one and a half million commercial buildings in the U.S. Less than ten percent of them have energy management systems. Technology from a Siemens company in Austin, Texas has what it takes to steadily ramp down this huge sector’s appetite for energy.
Although high-profile measures to slow global warming seem to be eternally stuck in neutral, a combination of technology and market forces offers the potential of putting a significant dent in energy demand and carbon dioxide emissions in the United States. According to a 2009 McKinsey report entitled “Unlocking Energy Efficiency in the U.S. Economy,” the commercial sector, which includes everything from office and retail buildings to hotels, restaurants and warehouses, will account for 20 percent of all the energy used in the U.S. by 2020, or about 20 quadrillion BTUs of primary energy.
Cutting energy bills
But even as average energy demand per square foot continues to grow at 1.5 percent per year throughout this vast sector, customers of Austin, Texas-based Siemens company Retail & Commercial Systems (RCS), which provides enterprise-level energy management for chains of mid-sized retail facilities such as health clubs, supermarkets and branch banks, are demonstrating that a completely different course is possible.
