Veröffentlichung Umwelt und Klima schützen - Wohnraum schaffen - Lebensqualität verbessern(Umweltbundesamt, 2023) Bartke, Stephan; Becken, Katja; Breitmeier, Maresa; Brozowski, Frank; DeTroy, Sarah Eileen; Grimski, Detlef; Ilvonen, Outi; Keßler, Hermann; Meilinger, Valentin; Messner, Dirk; Schlippenbach, Ulrike von ; Schlippenbach, Ulrike von; Schröder, Alice; Schuberth, Jens; Schubert, Susanne; Kommission Nachhaltiges Bauen am Umweltbundesamt; Deutschland. UmweltbundesamtDas Umweltbundesamt (UBA) und die Kommission Nachhaltiges Bauen am Umweltbundesamt (KNBau) haben Empfehlungen zur umwelt-, klima- und ressour-censchonenden und gleichzeitig klimaangepassten, gesundheits- und sozialverträglichen Schaffung bezahlbaren Wohnraums vorgelegt. Im Zentrum steht dabei der Umbau und die Umnutzung des Gebäudebestands, um die Ziele für Klima- und Ressourcenschutz im Gebäudesektor zu erreichen. Die Empfehlungen richten sich in erster Linie an die Bundespolitik mit den Ressorts für Bau- und Stadtentwicklung, Umwelt, Klimaschutz, Verkehr und Gesundheit. Darüber hinaus sind weitere Akteure angesprochen, wie politische Entscheidungs-träger*innen auf EU-, Landes- und kommunaler Ebene, Verbände, Planungspraxis und die Fachöffentlichkeit.

To improve the sustainability of construction materials, the leaching of substances from construction products and their potential environmental impact should be assessed. Twenty-seven construction products from different product groups were examined with a combination of standardized leaching tests (dynamic surface leaching test and percolation test) and biotests (algae, daphnia, fish egg, luminescent bacteria, umu and Ames fluctuation tests). To identify the released substances, extensive qualitative and quantitative chemical analyses were performed, including gas chromatographic and liquid chromatographic screening techniques. Results Many of the tested eluates caused significant ecotoxic effects. Particularly high ecotoxicities were observed for grouts (lowest ineffective dilution (LID) up to 16384) and cork granules (LID up to 24578). The results of ecotoxicity tests allow the prioritization of the eluates that should be subjected to detailed chemical analyses. Organic screening by different methods and ranking the identified substances based on recorded hazard classification is a suitable approach to identify the relevant toxic substances. Conclusions Determining the ecotoxicity of eluates from construction products records the summary effect of all leachable substances. This instrument is especially useful for construction products of complex and largely unknown composition. The ecotoxicological and the chemical-analytical approach complement each other in an ideal way to characterize the potential hazard of eluates from construction products and to identify the environmentally hazardous components in these eluates. Our results confirm that the proposed harmonized methods for testing eluate toxicity are an adequate and applicable procedure to move toward a more sustainable way of building and to reduce toxic effects of construction products in their use phase in the environment. © The Author(s) 2023Veröffentlichung Protecting the environment and climate - creating living space - improving quality of life(Umweltbundesamt, 2023) Bartke, Stephan; Becken, Katja; Breitmeier, Maresa; Brozowski, Frank; DeTroy, Sarah Eileen; Grimski, Detlef; Ilvonen, Outi; Keßler, Hermann; Meilinger, Valentin; Messner, Dirk; Schlippenbach, Ulrike von ; Schlippenbach, Ulrike von; Schröder, Alice; Schuberth, Jens; Schubert, Susanne; Kommission Nachhaltiges Bauen am Umweltbundesamt; Deutschland. UmweltbundesamtWe are facing an enormous challenge: the climate crisis and scarcity of resources require a consistent paradigm shift in housing construction and urban development. Quality of life, health and aesthetics must be combined with environmental, resource and climate protection. This position paper of the German Environment Agency and the Commission for Sustainable Building (KNBau) at the German Environment Agency presents recommendations for the creation of affordable housing that is environmentally, climate and resource efficient, and at the same time climate-adapted, health and socially compatible. The recommendations are primarily addressed to federal policy-makers, especially the departments of building and urban development, environment, climate protection, transport and health.

A low likelihood of microbiological growth is a relevant criterion when choosing ETICS. We examined whether a previously developed accelerated weathering test would be able to determine the ETICS' resilience to microorganisms and be suitable as a standard instrument to check the fitness for use of biocide-free ETICS renders and coatings. 15 different combinations of renders and façade coatings, including both new and established products, were tested for 15 weeks under accelerated weathering. The used lifelike weather conditions derived from climate data on an average autumn day in Holzkirchen, Bavaria are favourable for microbiological growth. Specimens were inoculated with a spore suspension containing fungi and algae typical for buildings derived from the institutes' own collection of building-relevant organisms. The results clearly show that biocide-free ETICS' coatings can be highly resistant to microbiological growth. Of the tested product variants, only two showed low or medium resilience. Additionally, we measured the formation of surface water condensation. Knowledge of the amount of condensation water accumulated during dew point shortfall usually confirms the results of the accelerated weathering test. However, contradictory results also exist. This can be explained by different evaporation times of condensation water on the surface of renders. The evaporation times depend on the render's inherent properties. Our results confirm that the used accelerated weathering setup is a suitable standard instrument to assess and compare the resilience of biocide free ETICS to microbial infestation. © 2023 Elsevier Ltd.
