Norman Foster honours plus energy houses

The Swiss Agency for Solar Energy (Solar Agentur Schweiz) found a prominent patron for its 20th anniversary of the Swiss Solar Awards. For the first time, outstanding plus energy houses had been nominated for the ‘Norman Foster Solar Awards’.
Lord Norman Foster, who’s residing in Switzerland since years, attended the ceremony on 3 September 2010 in Zurich. The total prize money for the new award is 100,000 Swiss franc. Furthermore, 17 other winners of the Swiss Solar Awards in three categories were honoured.

Winner of the Norman Foster Solar Awards:

Apartment building „Kraftwerk B“ in Bennau (1)
Plus energy house Cadruvi/Joos in Ruschein (2)
Plus energy refurbishment Züst in Grüsch (3)

The jury’s substantination for the first prize: Due to the 44 cm strong insulation of the 7-family plus energy house ‘Kraftwerk B’ produces 10% more energy as it consumes by itself. All surfaces directed south are used to produce solar energy by PV systems, so the roofs of house and pavilion provide about 32,000 kWh/a and the façade of the house about 30,000 kWh/a. The house forwards 10,000 kWh hot water to a building in the neighbourhood and purchases 7,000 kWh solar power into to public power supply system.
Winner of the Swiss Solar Awards, category new building:

Plus energy house Cadruvi/Joos in Ruschein
Mountain hut Sektion Monte Rosa bei Zermatt
IUCN administration building in Gland
Solar restaurant Klein Matterhorn, Zermatt
Winner of the Swiss Solar Awards, category refurbishment:
Plus energy refurbishment, Vaduz
Fents solar plus energy refurbishment, Wil
Minergie-P-refurbishment, MFH Rieben, Zurich
Winner of the Swiss Solar Awards, category plus energy building:
Solar plus energy refurbishment Ospelt, Vaduz
Plus energy building Sol-Arch2, Matten
Plus energy building Bürgi, Vordemwald
Remarkable is the surplus of solar energy of some the awarded buildings: The refurbished house Ospelt in Vaduz produces 182% of the energy that is consumed in it. The new insulation is 27 cm strong and the widows are triple-glazed. As a result the needed energy has been reduced about 86% to now 7,000 kWh. This means a lower CO2 emission of 18.1 tons per year.
