Annually, the Swiss Federal Office of Energy awards the Watt d’Or Award to people, companies and organizations that “develop the energy technologies for the future, bring innovative products onto the market and set new standards for practical solutions that unite energy and environment awareness with comfort requirements, aesthetics and economic interests”.
This year, a prototypical aerogel-insulated apartment building, devised by the Zurich-based architectural office Dietrich Schwarz has been awarded the Watt d’Or in the category Buildings and Space.
With new challenges in terms of energy efficiency and space requirements arising, architects are faced with a fundamental conflict — providing highly effective insulation at constant or even slimmer wall thicknesses. The only escape from this dilemma are advancements in insulation materials, yielding scalable structures of extremely low thermal conductivity.
Aerogels are one type of material promising exactly those required characteristics and therefore are generally considered to possess great merit for the future building insulation market.
Due to these intriguing insulating properties of aerogels, the architects of Dietrich Schwarz (Switzerland) have selected aerogel-equipped wood elements to insulate the exterior facade of their latest award-winning project in Zurich (see image above). Thereby, the building floor space was maximized without jeopardizing energetic requirements placed on modern architecture. Additionally, vacuum-insulated windows, phase-change materials in the facades reducing the required cooling and heating demands, rooftop PV panels and a thermal heat pump complete the holistic approach to reduce the energy intensity of modern housing.
Another eye-catching, futuristic feature of the apartment block are its convex oriels, providing sound insulation from the noisy street. Through these elements regular room ventilation via opened windows can be achieved without experiencing excessive noise pollution.
In light of the abundance of novel architectural elements, providing a high level of comfort at vastly reduced energetic footprint, found in this building concept, the selection of the jury of the Swiss Federal Office of Energy does not come as a surprise.
If building concepts such as the one by Dietrich Schwarz will prove their worth, it will only be a matter of time until aerogel-based insulation materials will become a market standard.
