Guía de diseño de emergencia climática - Iniciativa de transformación energética de Londres (LETI)

Estamos en una emergencia climática, y necesitamos reducir urgentemente las emisiones de carbono, esta guía describe los requisitos de los nuevos edificios para garantizar que se cumplan nuestros objetivos de cambio climático, estableciendo un viaje definitivo, más allá de las declaraciones de emergencia climática, hacia un futuro con cero emisiones de carbono. Está dirigido específicamente a desarrolladores / propietarios de tierras, diseñadores, responsables políticos y la cadena de suministro. Su objetivo es ayudar a definir lo "bueno" y establecer objetivos claros y alcanzables.

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.

Esta guía demuestra que la industria de la construcción sabe cómo deberíamos diseñar edificios. En 2020, los edificios que adopten estos requisitos ahora serán considerados líderes. Para 2025, estos requisitos deben convertirse en una práctica de diseño estándar, de lo contrario, la industria de la construcción no cumplirá con nuestra responsabilidad colectiva en esta crisis climática.

LETI cree que para cumplir con nuestros objetivos de cambio climático, en 2020 10% de todos los nuevos proyectos en los que están involucrados los desarrolladores y diseñadores, deben diseñarse para cumplir con los requisitos establecidos en esta guía. Los equipos de diseño tendrán la oportunidad de registrar sus proyectos como proyectos LETI Pioneer, para compartir conocimientos y superar barreras con otros equipos de diseño que trabajan hacia el mismo objetivo.

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).
