HILO - Zürich, Switzerland

Description

The current challenges faced by the construction sector primarily concern how to provide the ever-growing
global population with more living and working space. At the same time, the construction industry is responsible for a large proportion of the resource and energy consumption. The HiLo building on the roof of the NEST building of the ETH Zürich in Dübendorf shows that this is not always the case: The lightweight design impresses with its innovative construction and a selflearning building technology. Custommade, fire-resistant glazing ensures the necessary security.

Significant elements of the construction principle in the HiLo unit are, in addition to the conservation of material, the reduction of emissions and energy requirement. This is achieved through a combination of different measures, among which is the use of innovative components of the building technology which efficiently regulate the indoor climate. These include an adaptive solar façade developed especially for the HiLo unit, made from photovoltaic modules. There is also electrochromic glazing by SageGlass which regulates the brightness in the building and serves as solar and heat protection at the same time. The individual glass was directly adapted to the curved roof shape, for which no mechanical solar protection would have been possible. Where fire protection was required due to the proximity to other buildings, fire-resistant glazing in the form of CONTRAFLAM^® 30 CLIMATOP^® triple glazing by Vetrotech was used.
