Berkeley Labs conducts intelligent LED lighting tests in New York
According to foreign media reports, the US Department of Energy (DOE) Lawrence Berkeley National Laboratory (Berkeley Laboratory) has revealed in New York commercial office for solid-state lighting (SSL) related laboratory tests.
Berkeley Labs conducts intelligent LED lighting tests in New York
Berkeley Labs has partnered with the Building Energy Exchange (BEEx) to develop LED lighting projects, including integrated lighting, sensor sensors and curtain connection control. Berkeley Labs believes that this work will accelerate the market for smart lighting applications, and BEEx will use this work to promote its educational mission for business areas of lighting designers and staff to provide services.
In fact, the project team monitored the energy usage and other aspects of the office space throughout the year before retrofitting SSL and control measures. BEEx is the regional manager for the project.
As shown above, changing the T5 fluorescent light with dimmable LED fixtures provides direct and indirect lighting. Floor window with automatic tones. The connection sensor installed in most open spaces can detect local light and utilization.
Given that the omnipotent windows and daylight can heat the entire space, the test further takes into account the space of the thermal element. The test also utilizes a linear slot distributor that can be used to mitigate the rising temperature along the top of the window. In addition, a floor air blowing (UFAD) diffuser is used to improve airflow while achieving local control. In addition, thermal imaging is used to record the acceptable temperature of the entire reform space.
The intelligent lighting program is designed to balance the advantages of natural light and provide visual and thermal comfort and provide a comfortable working environment for workers. Sometimes need to reduce the shadow to reduce glare, but can be opened at other times; this will reduce the demand for artificial lighting, but also for the office to provide a comfortable environment.
The study focused on the 40-foot peripheral area of ??the office building. Compared with the baseline, BEEx monitored the power required to install the lighting down by 79% in six months. Peak demand for electricity also fell by 74%.
The study did not measure the energy supplied by the HVAC (heating, ventilation and air conditioning) systems. But the researchers estimated the impact on HVAC energy; and said the measurement data show that the entire building renovation can save $ 730,000 per year.
BEEx will assist the lighting community through related tools and other resources based on the test results of the project.
"Through the experience gained by the project, we have developed a range of tools that will really help design professionals or building owners make better decisions about lighting system upgrades," said Yetsuh Frank, general manager of BEEx's strategy and planning division.
