daylight harvesting control systems have become a common feature in green buildings, and with ASHRAE/IES 90.1 2010 now the baseline energy design standard, it also is expected to become a staple in mainstream construction.
Joel Spira, who founded Lutron Electronics Co. in 1961, invented the first solid-state dimmer in 1959. For decades after, dimmers were largely used to control the aesthetic environment. Only in recent years has dimming become an important part of the energy costs saving debate.
The next step is to develop the basis of design or design intent, which can be expressed using two best practice tools. The first tool is the lighting control narrative, a document that describes how the intended control system will satisfy the owner project requirements.
According to the Office Building Energy Use Profile report from the Environmental Protection Agency (EPA), space conditioning and lighting account for 70 percent of all energy consumed in a typical office building with an additional 20 percent of energy consumption used to power office equipment.
Housing starts in 2007 had declined by more than one-third from their 2005 peak, but the market for home technologies remains strong, according to the Sixth Annual State of the Builder Technology Market study conducted by the Consumer Electronics Association.
After Jeff McCullough's talk at Intertech’s LEDs October 2007 conference, an audience member declared that McCullough’s employer, the U.S. Department of Energy (DOE), is “taming the Wild West” and suggested that he wear a cowboy hat.
The recent national energy bill banning incandescent bulbs by 2014 has mandated energy-efficient residential lighting. Before introducing the latest lighting devices, electrical contractors (ECs) need to survey homeowners’ needs and lifestyles.
Hindering adoption of advanced lighting control strategies is the idea of whether these strategies work together in combination as advertised to produce consistent energy savings and worker satisfaction, thereby justifying a higher initial cost.
With 40-hour-plus work weeks the norm and no signs of that trend reversing, seeing well in the office at any time of day or night is necessary to get the job done. Illumination in the office can mean a combination of different types of light, artificial and natural.
Few areas of electrical contracting have changed at a rate greater than residential lighting controls. Residential product offerings have grown exponentially as social and political agendas continue to shape energy supplies—as more middle-income homeowners take control over lighting.
Speelman Electric assists housing authority in lighting installation When Ameresco was seeking a contractor for the Akron Metropolitan Housing Authority’s (AMHA) $10 million energy conservation project, the company called on Speelman Electric Inc., Tallmadge, Ohio.
Fueled by a hot real estate market, residential lighting manufacturers are creating products that integrate design and function at the onset. Although custom homes comprise 17 percent of all new homes, they account for almost 30 percent of all expenditures for building products.
