Guide de conception des urgences climatiques - London Energy Transformation Initiative (LETI)

Nous sommes dans une urgence climatique et avons un besoin urgent de réduire les émissions de carbone, ce guide décrit les exigences des nouveaux bâtiments pour garantir que nos objectifs en matière de changement climatique sont atteints - établissant un voyage dé fi nitif, au-delà des déclarations d'urgence climatique, vers un avenir net zéro carbone. Il s'adresse spécifiquement aux développeurs / propriétaires fonciers, aux concepteurs, aux décideurs et à la chaîne d'approvisionnement. Il vise à aider à définir le «bien» et à fixer des objectifs clairs et réalisables.

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.

Ces orientations démontrent que l'industrie du bâtiment sait comment nous devrions concevoir des bâtiments. En 2020, les bâtiments qui adoptent désormais ces exigences seront considérés comme des leaders. D'ici 2025, ces exigences doivent devenir une pratique de conception standard, faute de quoi l'industrie du bâtiment ne s'acquittera pas de notre responsabilité collective dans cette crise climatique.

Le LETI estime que pour atteindre nos objectifs en matière de changement climatique, en 2020, 10% de tous les nouveaux projets auxquels les développeurs et concepteurs sont impliqués devraient être conçus pour répondre aux exigences énoncées dans ce guide. Les équipes de conception auront la possibilité d'enregistrer leurs projets en tant que projets LETI Pioneer, de partager leurs connaissances et de surmonter les obstacles avec d'autres équipes de conception travaillant dans le même but.

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).
