RINNO joins Advantage Austria’s “Creative Approaches to Sustainable Building” event and reports on the latest in GlassTech and wasterwater management for sustainable construction and renovation solutions.
On March 4th, 2021, RINNO attended Creative Approaches to Sustainable Building, a full-day virtual event organised by Advantage Austria. The event brought together over 200 architects, construction professionals, developers and experts in sustainable construction. The event was dedicated to sustainable innovation and technological development in the construction sector, a particularly relevant topic for RINNO.
Andreas Simmer, the Managing Director of Internorm UK, delivered a session on ‘Windows of the Future’, Simmer identified three specific ways that windows can play an important role in contributing to energy efficiency and sustainability in construction:
Simmer also noted that the old windows can also contribute to sustainability and the circular economy through recycling and integration into UPVC for new products.
These approaches are not unfamiliar to the RINNO consortium. Indeed, as part of RINNO Greenstruct will develop plug-n-play modular building envelope solutions based on building-integrated photovoltaics (BIPV) and thermochromic glass to optimise the process of glass cladding and installation at our pilot sites. To measure the impact, we will monitor indoor microclimates with sensors to compare energy consumption results.
More about the benefits of BIPV and thermochromic glass can be read in our previous blog, GlassTech and How Can it Contribute to Energy Efficiency in Construction.
How can Wastewater Contribute to Sustainability?
Heating and cooling innovations were the subject of Ulrike Rabmer-Koller’s talk, Head of the Rabmer Group. Rabmer Group is a 2nd generation family business located in Upper Austria, and in addition to construction, environmental technologies has been a specific focus of the company for over 30 years. Currently, almost 50% of the total energy consumed in Europe is used for the generation of heat for either domestic or industrial use. A key focus for Rabmer Group has been capturing energy from exhaust air and wastewater.
24 hours a day and 365 days a year, the sewer regulates itself.
Against the backdrop of the UN’s Sustainable Development Goals, Rabmer-Koller feels we cannot miss the opportunity to examine the use of unavoidable outputs in domestic environments, whether solar, biomass, geothermal or exhaust, for improving sustainability. Wastewater in particular has its own advantages – nobody wants it and its high temperatures make it highly suitable for further use. According to Rabmer-Koller, 10-14% of the energy required by the construction industry can be met by wastewater by either integrating heat exchangers and pre-heating solutions (resulting in up to 60% of heat being regained to pre-heat water or heat buildings), or transferring wastewater heat from the sewer.

The Need to Raise Awareness About EU Environmental Technologies
These two innovations point to a significant issue in the context of environmental technologies and innovations. The solutions that companies like Internorm and the Rabmer Group have developed are relatively mature but remain relatively unknown to many construction and renovation stakeholders within the EU. Increasing stakeholder knowledge and awareness of sustainable alternatives is essential for hitting EU and SDG targets for sustainability and, indeed, deep renovation.
