Fusionopolis. A vertical city made of glass
von | Dec 22, 2009

The new address for technologies of the future and a futuristic lifestyle - the three towers of the "Fusionopolis" in Singapore. On up to 24 floors and 120,000 square metres, the Japanese star architect Dr. Kisho Kurokawa has designed a so-called "layered city". In a vertical orientation, it combines everything that an ordinary city provides for its inhabitants on an extensive sealed surface area: jobs, open roof gardens, retail shops, administrative offices, apartments, restaurants and a fitness studio with a rooftop pool. Fusionopolis is an impressive example of sustainable architecture. A particularly varied glass facade provides protection from the sun and privacy where necessary. It also scores with its exceptional design. More than 40,000 square metres of ipasol solar control glass by Interpane were used. Depending on the requirements of the corresponding part of the building the glass has an individual screen print design or a grey substrate.

The towers are relatively close together, so privacy has to be ensured whilst still preserving the scenic view for the inhabitants. The solution: wherever an office section is opposite an apartment, the external wall of the office is set back a bit in the façade, and roof gardens form a visual buffer zone. In these places, the outer pane of the façade glazing is additionally furnished with a sophisticated screen print pattern that tapers off towards the middle of the pane. Thus, an outward view from the inside is still possible, whereas the inward view from outside is restricted. The outside panes of the 30,000 square metres of the façade that are textured in this way consist of heat-strengthened glass. Thirtyeight percent of the glass surface is printed - in combination with the special ipasol solar control coating, this results in a solar factor of only 18 percent. The pane on the inside of the whole structure consists of laminated safety glazing.

A further 9,000 square metres of the heat-strengthened glass with screen printing have a backing of white sheet metal for visual reasons, or serve as a parapet in some exterior areas. In the apartments, an ipasol glass type with a higher light transmittance is used in some positions (ipasol neutral 73/42), which has been applied to a glass substrate with a grey hue for reasons of appearance. This combination livens up the largely white façade of the building and restricts the inward view from outside. From the inside, an excellent outward view is nevertheless ensured. In combination with grey glass of eight millimetre 8 strenght, the solar factor decreases to 26 percent. This substantially reduces the costs for air conditioning.
