Microclimate building design
The global climate has been gradually warming, and the frequency and duration of extreme heat events have been increasing. These trends are being exacerbated by urban heat island intensification (UHII), resulting in increasingly dangerous heat waves in many cities. Research has identified the main causes of UHII and suggested ways that cities can be designed so they are cooler rather than hotter during heat waves. This information is often very technical and is not generally available to the professionals designing urban environments, but recently there has been an increased interest by landscape architects to apply this information, generally known as microclimate modification, to their profession.
Towers in Singapore create their own microclimate. These twin towers have been awarded the "Urban Habitat: Single Site Scale Award of Excellence" by the Council on Tall Buildings and Urban Habitat (CTBUH). The dramatically formed structures are called "DUO". This was to create a new sense of urban habitat in which humans, architecture, and nature can coexist in productive and socially responsible ways. The tower's shape helps to provide a cool microclimate.
Built on the main route into the city from Singapore’s Changi Airport, DUO is a highly connected commercial and residential centre. DUO’s design demonstrates how a landmark building can be carefully embedded within a commercial area as well as how a building’s form can be both practical and sculptural.
The curved facades feature a textured honeycomb shading system that protects the building from heat and glare without obstructing views of the ocean or the wider cityscape. Within the site are a diverse range of public spaces. The buildings’ geometric form creates a landscape of covered and open-air gardens, walkways, cafes, and restaurants.
The orientation of the buildings is designed to maximise natural light, and their concave shape captures and channels wind flow through the site, creating cooler microclimates.The integration of architecture and nature allows DUO to accomplish a "100% landscape offset," which means it's created new green space equivalent to the site’s original unbuilt area.
