Isabelle Durant, vice-president of the European Parliament, presented the winners of the second European Aluminium in Renovation Award 2009, including two energy efficiency winners, in the European Parliament's Brussels premises on 18 November 2009. Energy Efficiency Winner in the residential category is "Torenflat" in Zeist (NL), by Frowijn de Roos Architecten, who enclosed the high-rise apartment block in a "warm jacket". Winner in the non-residential category is "Energia" Building in Paris (F), by Architecte DTAAC, who met the French High Environmental Quality standard (HQE) including energy efficency.

Residential winner: "Torenflat" in Zeist (NL), Frowijn de Roos Architecten

The Torenflat (high-rise apartment block) contains 484 apartments on central corridors on 19 residential levels. One of the important objectives of the renovation, which was carried out entirely whilst people were living in the building, was the elevation of all thermal bridges in the complex. This was tackled by enclosing the whole building in a ‘warm jacket’, a thermal skin comprising fully prefabricated aluminium façade units. By enclosing the building in this way, balconies were turned into loggias, thereby considerably increasing the duration of use of these outdoor spaces during the year. The traditional ‘layer cake’ appearance of the block has been transformed into a monolithic character.

From the Jury: "The new thermal skin in aluminium and glass makes it possible to considerably extend use of this high-rise apartment block. This resolves the thermal bridges and the original balconies are added to the living area in the form of loggias. The prefab aluminium façade units were extremely well suited to carrying out such an operation. An apartment was given a new skin in one working day. It combines minimal investment with a maximum of social economic impact. An outstanding performance and a model for future renovation of energy efficient apartment buildings of this type all over the world."

Non-Residential winner: "Energia" Building in Paris (F), Architecte DTAAC

This renovation and restructuration of this building near the Saint-Lazare station shows a nice combination of contemporary aesthetic, homogeneous and modern design. Main target of this renovation also is the energy efficiency and environmental approach achieved by noise reduction, waste and dust reduction. After completion the building meets the High Environmental Quality (HQE) standard. The best qualification possible.

The Jury was impressed about the nice and carefully detailing in windows and cladding approach. The outstanding energy efficiency and environmental performance makes this project an absolut winner of the energy efficiency in the Category Non-Residential.
