GBB Award: Rabmer wins sustainability prize

The Green & Blue Building Award brings sustainable projects and technologies in the real estate industry before the curtain. The Upper Austrian construction and environmental technology company Rabmer secured first place in the “Products/Services” category with its innovative solutions for energy from wastewater for sustainable heating and cooling of buildings.  

(Vienna/Altenberg, 27 January 2021) A green prize for green technology – instead of trophies or medals, small bonsai pepper trees are awarded at the GBB Awards. The plants are meant to symbolise responsibility in the real estate industry – even their pots are committed to sustainability. The chairman of the jury, Marc Guido Höhne, makes them himself. He is actively supported by the team of Ghezzo GmbH, which is responsible for the annual award ceremony together with Drees & Sommer. The most recent event took place on 26 January 2021 via online conference due to Corona.

In the category “Products / Services”, the Rabmer Group was able to celebrate and enter the list of sustainability winners. The Upper Austrian company entered the race for the bonsai with “Energy from Waste Water”. According to the GBB rules, ecological impact, innovative strength and life-cycle relevance serve as criteria for the awarding of the podium places. Rabmer’s solutions for using wastewater energy to heat and cool buildings scored highly in all three areas.

Essential contribution to climate protection

Wastewater is becoming more and more known as a renewable energy source also in this country. Rabmer is a pioneer in this field in Austria. Using innovative heat exchanger systems, thermal energy is extracted from the wastewater, which is then used – boosted by heat pumps – to heat and cool buildings.

“We are very pleased about this award. Energy from wastewater’ has enormous potential and, above all, makes a significant contribution to climate protection. Currently, mainly CO2-critical energy sources are used to cover the heating and cooling needs in buildings. With our solutions, up to 12 percent of all buildings in Austria could be heated and cooled in an environmentally friendly way,” says Ulrike Rabmer-Koller, Managing Director of Rabmer.

“Energy from wastewater” impresses not only with sustainability but also with rapid amortisation. For the jury of the GBB Awards, the monetary advantages were admittedly less decisive than the climate-friendly aspects of Rabmer’s technology. “We were particularly convinced by the high life-cycle relevance of this technology. We believe that energy from wastewater should be evaluated in every major project. And we also want to provide the impetus for this,” explained Marc Guido Höhne when the prize winners were announced. The bonsai pepper tree will have a place of honour at the company headquarters in Altenberg. It will be presented in February in strict compliance with the safety rules, provided the Corona location allows it.
