Motion and Daylight Harvesting: Conserving Energy with Sensors

By Sarah RonkoskeDecember 17, 2017

Increasing energy costs are driving building owners, utilities, end-users, and governments all over the world to adopt effective strategies that support sustainable energy-saving initiatives. Likewise, the global lighting industry has converged to produce more energy-efficient fixtures through the deployment of evolving technologies, particularly around light-emitting diodes (LEDs).

LEDs, besides offering higher efficacy, also provide the opportunity to integrate a greater density of sensors, which can be leveraged for improved and enhanced control options for energy-savings. Sensor-enabled LED controls can save energy and money by using lights only when it is necessary. Sensors like motion-based sensors, daylight sensors, and occupancy sensors help in creating cooler and more productive spaces for employees, residents, and customers alike.

What Is Daylight Harvesting?

Daylight harvesting measures available natural light to control indoor lighting, which facilitates energy conservation at an optimal level. Various studies suggest that daylight harvesting can boost the performance of students in schools, and heighten the efficiency of employees. It can also create more appealing retail spaces that increase customer visits and purchase rates. These are also some of the reasons why buildings that utilize daylight harvesting often have higher lease rates and increased resale values. 

Motion and Occupancy Sensors

Occupancy and motion-based sensors shut off, or dim the lights as and when required, depending on the occupancy. These sensors can be installed in indoor spaces, an industrial, or even an outdoor area. Research reveals that average energy savings ascribable to motion-based controls are to the tune of 24 percent. However, this may vary according to occupancy rates in a specified location.

Installing energy-efficient lighting controls can be both mentally and financially taxing if lighting products available on the market are not well understood. Therefore, it is important to engage qualified and professional lighting specialists such as McWong International, Inc.
