Building automation is the automatic centralized control of a building’s heating, ventilation and air conditioning, lighting and other systems through a Building Management System or Building Automation System (BAS). The objectives of building automation are improved occupant comfort, efficient operation of building systems, and reduction in energy consumption and operating costs.
In the late 1880s, the Swiss Army purchased a new style of folding pocket knife for its soldiers. It was equipped with a tool able to open food rations in the field and disassemble the standard-issue Swiss rifle, the Schmidt-Rubin, which required a screwdriver.

It is estimated by the US Department of Energy (DOE) that 30% of energy used in commercial buildings is wasted. While unnecessary power consumption represents one aspect of wasted energy, inefficient use represents another. To optimize energy use, buildings have historically used Building Automation Systems (BAS) or Building Management Systems
The good news in energy management is that many of the challenges in effectively monitoring and controlling HVAC systems have been overcome. Many buildings—both new construction and retrofits—use efficient heating and cooling systems that are optimized with building automation systems (BAS). Plus, under the latest building codes, building envelopes are

Intrusive noise is a growing concern for both the public and private sector these days. If the power equipment rattles, clanks, and booms loudly, there will likely be complaints—or worse: fines and citations. Consider this: according to the Noise Pollution Clearinghouse (www.nonoise.org), 13 states have noise pollution laws, and five provide model
Efficiency is the buzzword for innovations in HVAC technologies. “Government mandates are requiring higher efficiencies overall from the building, which includes everything from the HVAC all the way to the glass in the door,” points out Steve Ulm, spokesperson for SEMCO. “Efficiency is driving the construction industry as a whole.”

Digital technology has created a revolution in building controls, relegating old pneumatic instruments to the antique shops along with typewriters and calculating machines. Now, a control system can allow a technician to turn fans on or off, and/or modify temperatures or lighting in a structure from a tablet or laptop
Arc flash events in electrical distribution systems can be devastating, costing up to $15 million in direct damages and indirect costs, such as health care, workers compensation, and others (EPRI 1999). An arc flash can generate temperatures over 35,000°F and projectile-producing pressures equivalent to 700 miles per hour, and is
Over a beer with good friends at Johnson Controls, Harshad Shah—a native of Mumbai, India—learned of the need for more energy management in facilities. “I listened to a lot of horror stories—why some of the things weren’t working—and about the cost of energy going up,” he says.

The Internet has made possible a revolution in power controls—a revolution often referred to as the Internet of Things (IoT). Until it—and the fiber optics that connect us all—came along, plant machines operated in their own universes, leaving facility engineers unable to understand how whole plants work together, and unable to find operating
