In 2012, Facebook was responsible for about 384,000 metric tons of CO2e, up from 275,000 in 2011, according to the company’s annual report on carbon emissions and energy use. This includes GHGs from data centers, office space, employee commuting and air travel, data center construction and hardware transportation.
Key advances in smart building technology are ushering in a new era of building energy efficiency and carbon footprint reduction. And those same technologies are yielding rapid returns on investment for building owners within one to two years.
Heating, ventilation, and air-conditioning (HVAC) equipment, such as boilers, chillers, air handlers, furnaces, and heat pumps, make up some of the largest sources of energy consumption in most buildings. Not surprisingly, there is a big opportunity to optimize and reduce this consumption with better management and equipment improvements.
Net zero energy describes buildings whose energy consumption and emissions are fully offset by renewable energy, preferably generated on site. True to their net zero name, they generate as much or more clean energy as they consume.
The new addition to Calvert High School in Prince Frederick, Md., celebrates the sun, inviting daylight into virtually every corner of its multi-use media center. The addition features huge skylights that are 31 to 41 ft above the floor, more than 35 ft long, and pitched at a 16-deg angle. The skylights span 17,000 sq ft.
Advanced lighting has brought us not only energy savings, but also a slew of new screw-in-a-light bulb jokes. For LEDs, it usually goes something like this: How many people does it take to screw in a LED light? One. And a roomful of deep wallets to pay for it.
