According to foreign media reports, the US Department of Energy (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) recently revealed solid-state lighting (SSL)-related laboratory tests in commercial office buildings in New York. Berkeley Labs has partnered with the Building Energy Exchange (BEEx) to develop LED lighting projects that include integrated lighting, sensor sensors, and curtain connection controls. Berkeley Labs believes that this work will accelerate the market application of smart lighting, and BEEx will use this work to advance its educational mission to serve lighting designers and staff in the commercial sector. In fact, the project team monitored the energy usage and other aspects of the office space throughout the year before modifying SSL and control measures. BEEx is the regional manager for the project. As shown above, the replacement of T5 fluorescent lamps with dimmable LED luminaires provides direct and indirect illumination. Floor-to-ceiling windows are available in automated tones. Connected sensors installed in most open spaces can detect local light and utilization. The test further considers the thermal elements of the space, given that the ubiquitous windows and daylight can heat the entire space. The test also utilized a linear slot disperser that was used along the top of the window to alleviate the temperature rise. In addition, a floor air supply (UFAD) diffuser is used to improve airflow while achieving local control. In addition to this, thermal imaging is utilized to record the acceptable temperature of the entire retrofit space. The intelligent lighting program is designed to balance the benefits of natural light, provide visual and thermal comfort, and provide workers with a comfortable working environment. Sometimes it is necessary to reduce the shadows to reduce glare, but it can be turned on at other times; this reduces the need for artificial lighting and provides a comfortable environment for the office. The study focused on the 40-foot peripheral area of ​​the office building. Compared to the measured baseline, within six months, the power required by BEEx to monitor the installed lighting was reduced by 79%. Peak electricity demand also fell by 74%. The study did not measure the energy supplied by the HVAC (heating, ventilation, and air conditioning) system. But the researchers estimated the impact on HVAC energy; and said the measurement showed that the entire building renovation could save $730,000 a year. BEEx will assist the lighting community with relevant tools and other resources based on the test results of the project. Yetsuh Frank, General Manager of BEEx Strategy and Planning, said: "Through the experience gained from the project, we have developed a series of tools that will really help design professionals or building owners make better decisions about lighting system upgrades."
