Moy Isover International awards
The EU may be at the forefront of pushing energy efficient building, but innovative low energy construction is rarely recognised on a European scale. The Isover Energy Efficiency Awards are one exception, rewarding the continent’s best new build and renovation projects. We profiled buildings from the inaugural Irish awards in our last issue — here are nominations from across the continent that were celebrated at the European awards ceremony in Barcelona on 2 June
K3 House
Hörbranz, Austria
Architect: Hein-Troy Architecture

Renovation

K3 House
Timber annexes

This project by Hein-Troy Architecture took a large 1960s single-family home and turned it into an energy-efficient, modern complex of three separate homes. The house was renovated to accommodate two young families who wanted to live on top of their parents’ house, while the basement now serves as a communal space for the families.

The first task for the architects was to remove the loft roof and the garage adjoining the house, then add timber annexes at the top and sides. The project presented some major challenges, such as doubling the living space while reducing the building’s energy use, and finishing the project while the parents were still living on the ground floor. Set at the foot of the Alps, the architects also aimed to maximise the house’s views over scenic Lake Constance.

Open plan split level interior

As part of the renovation, the building was wrapped with Isover façade insulation plates. It boasts excellent airtightness for a renovation — 0.80 m3/h/m2 — and excellent U-values of 0.22 W/m2K for walls and 0.13 W/m2K for the roof. The renovation slashed the building's energy use by 70%.
