Gestaltungsleitfaden für den Klimanotfall – London Energy Transformation Initiative (LETI)

Wir befinden uns in einer Klimakatastrophe und müssen die CO2-Emissionen dringend reduzieren. Dieser Leitfaden skizziert die Anforderungen an neue Gebäude, um sicherzustellen, dass unsere Klimaschutzziele erreicht werden – und begibt sich auf eine endgültige Reise über die Klimanotstandserklärungen hinaus in eine Zukunft ohne CO2-Ausstoß. Es richtet sich speziell an Entwickler/Landbesitzer, Designer, politische Entscheidungsträger und die Lieferkette. Es soll helfen, „gut“ zu definieren und klare und erreichbare Ziele zu setzen.

​

The Climate Emergency Design Guide covers 5 key areas: operational energy, embodied carbon, the future of heat, demand response and data disclosure. Our methodology includes setting the requirements of four key building archetypes (small scale residential, medium/large scale residential, commercial offices, and schools). The guide was developed by over 100 LETI volunteers over a period of 12 months.

Dieser Leitfaden zeigt, dass die Bauindustrie weiß, wie wir Gebäude entwerfen sollten. Im Jahr 2020 werden Gebäude, die diese Anforderungen jetzt übernehmen, als führend angesehen. Bis 2025 müssen diese Anforderungen zur Standardplanungspraxis werden, sonst wird die Bauindustrie unserer gemeinsamen Verantwortung in dieser Klimakrise nicht gerecht

LETI ist der Ansicht, dass zur Erreichung unserer Klimaschutzziele im Jahr 2020 10% aller neuen Projekte, an denen Entwickler und Designer beteiligt sind, so konzipiert sein sollte, dass sie die in diesem Leitfaden festgelegten Anforderungen erfüllen. Designteams haben die Möglichkeit, ihre Projekte als LETI-Pionierprojekte zu registrieren, Wissen auszutauschen und Barrieren mit anderen Designteams zu überwinden, die auf das gleiche Ziel hinarbeiten.

Reclaimed and Reused: Recommended LCA Modeling Guidance to Support EPDs for Reused Construction Materials

Material reuse is one strategy for reducing the embodied carbon of construction. While the preparation of previously used materials for reuse has an environmental impact, it avoids many of the resource extraction and manufacturing impacts of building with newly manufactured products. Given the amount of demolition and deconstruction across North America (and beyond), there is a vast potential for material reuse to expand in scale. However, barriers to material reuse scaling exist.

DEQ Low Embodied Carbon Housing Program: Roadmap to Success

Embodied Carbon Pathways to 2050 for the United States, a collaboration between the Carbon Leadership Forum (CLF), RMI, and the University of Washington (UW) Life Cycle Lab, provides an assessment of embodied carbon from US construction materials and explores pathways to align with a 1.5°C global warming limit.

International Embodied Carbon Data Availability: A Review of Environmental Product Declaration (EPD) Availability in Europe, China, and Australia

CLF completed a landscape analysis of product-level embodied carbon data availability in regions outside North America with the goals of: (i) understanding how LCA/EPD data availability varies globally; (ii) informing where targeted initiatives are needed to increase the availability of data; and (iii) determining whether adequate EPD data exists to develop CLF Material Baselines outside North America. This report summarizes our findings and provides initial insights into what data is available to inform low-carbon procurement efforts in Australia, China, and Europe.

The CLF Benchmark Explorer

Emissions from the operations of buildings and infrastructure are significant, well-understood contributors to national and global greenhouse gas emissions. However, the contribution of embodied carbon—emissions associated with the manufacturing, transportation, installation, maintenance, and disposal of construction materials across the life cycle of a building or asset—is neglected by comparison. Even at the global level, embodied carbon estimates are typically based on manufacturing emissions from the production of a handful of the highest-impact materials (e.g. concrete, steel, aluminum, and wood).
