SINGAPORE -- Hotels, stores and shopping malls in Singapore, looking for a way to cut their air conditioning bills and spruce up their environmental image, are increasingly adding greenery to their exterior walls.
The 27-story Oasia Hotel Downtown in the Tanjong Pagar business district, whose outer mesh cladding is swathed in trailing green plants, stands out among its high-rise neighbors. The Parkroyal on Pickering, a hotel in nearby Chinatown, has layers of balcony gardens.
