BEE Urges AP to Bring Residential Buildings Under ECBC
C
hief Secretary to the Government of Andhra Pradesh, AC Punetha, has recently reviewed the power sector and said that the Bureau of Energy Efficiency (BEE) has urged the state to consider bringing residential buildings under energy conservation building code (ECBC). Punetha also issued the directions to all government departments in Andhra Pradesh to implement energy efficiency measures on a priority basis. He said the government was promoting energy efficiency activities as part
of the second phase of power sector reforms to provide costeffective and quality power. The chief secretary was addressing the eighth executive committee and the fifth annual general body meeting of AP State Energy Conservation Mission (APSECM). AP is the first state in the country to retrofit the LED street lights in the municipal sector. The state has already retrofitted 6.21 lakh street lights in 110 urban local bodies and saved about 133 million units. About 20% energy can be
saved from commercial buildings following the ECBC norms.
Scientists Develop Smart Window to Trap Air Pollutants
S
cientists have developed flexible smart windows that can trap air pollutants and can also keep the indoor free from harmful matters. Tuning the light intensity and reducing the concentration of atmospheric particulate matter (PM) in commercial buildings are both crucial to keep indoor people comfortable and healthy. Smart windows fabricated on the flexible and transparent silver (Ag)-nylon electrodes can tune the light intensity entering commercial buildings to maintain thermal comfort. However, fabricating a large-scale transparent smart window for high-efficiency PM2.5

capture has been a significant challenge, until now, researchers said. Scientists led by YU Shuhong from the University of Science and Technology of China (USTC) developed a simple solution based process to fabricate largearea flexible, transparent windows for that can efficiently capture PM2.5. Recently, a research team led by Prof. YU Shuhong from the University of Science and Technology of China (USTC) has developed a simple process to fabricate 7.5 m2 Ag-nylon flexible transparent windows for highefficiency PM2.5 capture with
only about 15.03 dollars and 20 minutes. The obtained Ag-nylon window material serves not only to turn the indoor light intensity as thermochromic smart windows after uniformly coated with thermochromic dye, but also to purify indoor air as high-efficiency PM2.5 filter. The stablility of obtained material is also outstanding. Its performance remains stable after 10,000 bending cycles. In addition, even after 100 cycles of PM filtration and cleaning process, it still exhibits a removal efficiency of 99.65%.
