Building a green Singapore
More buildings get energy-saving features; aim for 80% to be green by 2030
In the concrete jungle of the Central Business District, a red flower-like structure stands out against the skyline.
Called a wind scoop, it perches atop the 40-storey CapitaGreen and its "petals" draw in cooler, cleaner air that is funnelled through the building's air-conditioning system, helping to save energy on cooling.
It is among the energy-saving features introduced in buildings in recent years, with the Building and Construction Authority (BCA) aiming for 80 per cent of buildings in Singapore to be green by 2030.
Cooling systems are a big drain on power, taking up 40 per cent to 50 per cent of a building's energy consumption. Together with other energy-saving features, such as a double-skin facade to reduce heat gain, the wind scoop helps CapitaGreen generate monthly savings of about 580,000kwh - equivalent to the energy needed to power about 1,500 four-room Housing Board flats in a month.
