Occupancy sensors automatically save energy by reducing lighting after a space is vacated. After more than 10 years of tightening commercial building energy codes, they are a staple in new construction projects. The rapid development of radio-frequency (RF) wireless occupancy sensors is making them more economically attractive for existing construction, too. READ MORE

While the light-emitting diode (LED) has gotten a lot of attention in recent years, another revolution has quietly developed in the background: intelligent (digital) lighting control. The future of lighting is solid-state, and it will be highly controlled.

Dimmable lighting control has seen limited application in commercial buildings. However, due to two primary factors, adoption has grown. First, commercial building energy codes that require daylight harvesting have increased demand for lighting that could respond transparently in regularly occupied spaces. READ MORE

The 2008 housing-market crash ended the home construction boom. A steady recovery began in 2012, and it continues today, bolstering the U.S. economy. Historically, residential construction averages 5 percent of the country’s gross domestic product.

In December 2015, President Obama signed a new tax bill into law, extending the Commercial Buildings Tax Deduction (CBTD, or Section 179D of the tax code) for two years, while raising the bar for efficiency. Created by the Energy Policy Act of 2005, the CBTD offers a financial incentive to encourage investment in energy-efficient building systems and envelopes.

The proliferation of automatic lighting controls is creating demand for commissioning services, including functional testing. While commissioning—a quality assurance process—is required in many new construction projects, research suggests that applying elements of the commissioning process to existing installations can optimize performance and energy savings.

From making clothing look vibrant in a retail store 
to facilitating interaction in offices by properly rendering skin tones, a light source's color quality is an important specification characteristic. For this, we use two metrics, correlated color temperature and the color rendering index (CRI). Varying these color qualities can affect how objects, spaces and people appear to the eye.

Solid-state lighting, such as light-emitting diode (LED) technology, promises significant short-term opportunities, notably in the retrofit market. However, many industry stakeholders are concerned about long-term risks LEDs present as they continue to gain acceptance.

Light doesn’t only serve as the basis of vision. It can influence behavior and how people feel. Further, light plays an important role in human health. As researchers gain insight into the relationship between light and health, the lighting industry is beginning to consider health effects in product and lighting design best practices.
