A layer of green foliage blankets a red tower in the heart of Singapore's business district, a feature that helps keeps the building cool as the densely-populated tropical city battles rising temperatures. The Oasia Hotel Downtown, in the heart of Singapore's business district, was designed to stay cool with the help of more than 20 species of creeping plants growing on its bright red aluminum facade. Its facade is 10 to 20 degrees Celsius cooler compared to nearby buildings, according to architecture firm WOHA, which designed the building. The 27-story structure houses over ten times the amount of greenery found on the site before its construction, and its large open terraces allow natural ventilation and lighting and reduce energy use. In an effort to reduce emissions, Singapore aims to green 80 percent of its buildings by 2030. Buildings account for over 20 percent of the city-state's carbon emissions.
Humans have destroyed about two-thirds of the world's original tropical rainforest and in the process destroying the natural buffer against climate change. This is affecting human livability and maybe pushing it beyond its limit.
When it comes to energy efficiency, France is lagging behind its European neighbours, trailing Germany, Sweden, the United Kingdom and the Netherlands. Nearly seven million French people live in residences known as "passoires énergétiques" or energy sieves. These homes have an energy rating of F or G, meaning it's too cold in winter, too hot in summer and importantly, it adds considerably to the country's carbon footprint.
