Knauf and Knauf Insulation have won the Award for Energy Efficiency and Renewable Energies in the Building Sector for their contribution to one of the most sustainable homes in Spain.

Knauf and Knauf Insulation have won the Award for Energy Efficiency and Renewable Energies in the Building Sector for their contribution to one of the most sustainable homes in Spain.

Presented by the German Chamber of Commerce for Spain and promoted by the German Federal Ministry of Economy and Climate, the award recognises innovative energy-saving solutions in the construction industry and outstanding collaboration between German and Spanish companies.

A wide range of Knauf  and Knauf Insulation solutions were installed in the villa known as Casa Sophia which was built by the Spanish company 100x100 Biopsavia.

The use of our Mineral Wool solutions and systems significantly reduced the operational emissions of the villa by 76% compared to a conventional home. Additionally, with the installation of photovoltaic panels and the inclusion of two electric vehicle-charging stations, Casa Sophia now generates more energy than it consumes.

The building has been certified Passivhaus Premium and awarded the highest ‘five-leaf’ level of certification by the Spanish Green Building Council. During construction 100% of the waste was recycled and all construction emissions completely off-set.

Exceptional levels of sustainability

At the awards ceremony held on November 22 in Madrid, the judges praised the villa’s zero waste achievement and its net positive carbon footprint. They also highlighted that the Knauf and Knauf Insulation solutions installed in the villa made a valuable contribution to indoor air quality, acoustic comfort and energy efficiency.

These solutions included Naturoll 032 for internal walls, our Smart Wall FKD-N Thermal for the façade and Panel Plus TP 138 with E-Technology® for internal partitions. Panel Plus contains no added formaldehyde and has been certified free of harmful ingredients by DECLARE.

In addition, formaldehyde-purifying Diamant Cleano C Panels from Knauf were also installed to provide effective acoustic comfort and any off-cuts were recycled to ensure zero waste to landfill.

The final touch involved incorporating our Urbanscape® green roof solution. Green roofs provide excellent CO2 absorption, promote biodiversity and provide effective stormwater management. Urbanscape also helps reduce the temperature of buildings in hot weather.

‘The best way to build today’

Oscar Del Río, General Manager of Knauf Insulation Iberia, said: “Casa Sophia represents the best way to build today in terms of energy efficiency, sustainability and healthy building. That is why we are proud to have participated in this unique project and have our contribution recognised by the German Chamber of Commerce for Spain.”

Pablo Maroto, Marketing and Technical Director of Knauf Ibérica, said: “Casa Sophia has been certified Passivhaus Premium for being net positive. It has received 92% in the five-leaf Green Seal from the Spanish Green Building Council — the highest score ever — and has received the Voloriza label and Recycle label for producing zero waste.

“The villa has been recognised by the companies CoCircular and Ecometer for its low environmental impact and net positive carbon footprint and awarded the Excellence Seal by the European Commission’s Horizon 2020 programme for energy efficiency and sustainability. Such a level of recognition and certification makes Casa Sophia unique.”
