Buildings consume nearly 40% of the world's energy, and in the past 20 years the building industry has focused on sustainability, efficiency, and practical energy-saving solutions for both new construction and retrofits. Energy for lighting represents led high bay light manufacturers large share of building energy consumption. The lighting industry is making steady progress toward sustainability via efficient LED-based products and networks and adaptive controls. Still, lighting designers and specifiers are faced with meeting ever-more-stringent regulatory standards for lighting projects. We will discuss the most demanding requirements here - particularly in terms of required controls and the ASHRAE 90.1-2013 requirements.
Total light management systems can be integrated with building management systems to include astronomic timeclock interface or photosensor control of exterior lighting including façades, signage, and landscapes.

As the building industry moves slowly toward zero net energy - the goal of the Architecture 2030 (architecture2030.org) program and key in the roadmap of the US Department of Energy (DOE) - the industry is recognizing that lighting controls play a crucial role in . energy conservation According to the DOE, lighting is by far the largest end user of electricity in commercial buildings It consumes 38% of a building's total electricity use -. approximately the same as space heating, cooling, ventilation, office equipment, and computers combined , according to a US Energy Information Administration study published in 2008.
Lighting controls can eliminate 60% or more of the wasted lighting energy in buildings, while enhancing occupant comfort and productivity. They provide flexible control over the lighting in a space, and support energy savings by reducing the amount of power or time the lighting system is in use. Energy is the multiplicative product of, in this case, lighting power and the power-on time during which it is used. Lighting controls can reduce both power and time.
One of the nation's top three building energy codes and standards - Part 6 of Title 24 of the California Code of Regulations, the International Energy Conservation Code (IECC), and ANSI / ASHRAE / IES Standard 90.1 - is used by nearly every state as the basis for local building energy codes. These provide the minimum acceptable energy performance requirements for new construction or major renovations of commercial buildings. They reflect the importance of using lighting controls to conserve energy. They have similar mandatory lighting control requirements for new construction or major renovation projects.
Sometimes referred to as America's primary commercial energy code, the latest version of ANSI / ASHRAE / IES Standard 90.1 was published in October 2013 and is known as Standard 90.1-2013. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE ) partners with the Illuminating Engineering Society (IES) to produce the standard. led high bay light price provides the minimum requirements for the energy-efficient design of buildings, other than low-rise residential buildings.
Rita Harrold, director of technology for the IES, said achieving the stringency goals established for the 2013 standard presented a challenge in reducing the requirements for lighting. "While interior lighting power densities (LPD) were re-evaluated and most lowered, there continues to be an ongoing concern about maintaining quality of lighting installations for occupant satisfaction and comfort while achieving energy savings, "said Harrold." The focus in the 2013 standard, therefore, was not just on lowering LPDs but on finding ways to achieve savings by adding more controls and daylighting requirements as well as including lighting limits for exterior applications based on jurisdictional zoning.
