NSG Cool Vacuum Glazing Selected for Fukuoka City Hall
NSG Spaci has been used for the new windows of Fukuoka City Hall in southern Japan.
NSG Spacia™ has been used for the new windows of Fukuoka City Hall in southern Japan. During the city hall renovation in May-June 2015, 670 windows in the west side of the building between the second and 14th floor were replaced by NSG glass.
Fukuoka City Hall needed to address summer heat problems and reduce air conditioning costs, especially because of large windows that let in the glare of late-afternoon sun. After considering several options, including heat reduction films, Spacia Cool was selected due to its high solar heat gain reduction, ease of installation, shortened panel replacement time and future maintenance cost savings.
Summer temperature readings after the renovation demonstrated that window surface temperature reportedly was 5°C lower compared with the old panels, while the temperature inside the room dropped by 6.4°C. Spacia Cool also demonstrated high heat insulation performance due to limited condensation on glass, even during a very unusual cold blast in the south of Japan in January 2016. The city is reportedly planning further initiatives to mitigate the effects of global climate change, including the creation of subsidies for energy-saving renovations of residential buildings.
