Guida alla progettazione dell'emergenza climatica - London Energy Transformation Initiative (LETI)

Siamo in un'emergenza climatica e abbiamo urgente bisogno di ridurre le emissioni di carbonio, questa guida delinea i requisiti dei nuovi edifici per garantire il raggiungimento dei nostri obiettivi sui cambiamenti climatici, definendo un viaggio definitivo, oltre le dichiarazioni di emergenza climatica, verso un futuro netto a zero emissioni di carbonio. È specificamente rivolto a sviluppatori/proprietari terrieri, progettisti, responsabili politici e alla catena di approvvigionamento. Mira ad aiutare a definire "buono" ea fissare obiettivi chiari e realizzabili.

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.

Questa guida dimostra che il settore edile sa come dovremmo progettare gli edifici. Nel 2020 gli edifici che adottano questi requisiti ora saranno visti come leader. Entro il 2025 questi requisiti devono diventare una pratica di progettazione standard, altrimenti l'industria edile non si assumerà la nostra responsabilità collettiva in questa crisi climatica.​

LETI ritiene che per raggiungere i nostri obiettivi di cambiamento climatico, nel 2020 10% di tutti i nuovi progetti in cui sono coinvolti sviluppatori e designer, dovrebbe essere progettato per soddisfare i requisiti stabiliti in questa guida. I team di progettazione avranno l'opportunità di registrare i loro progetti come progetti LETI Pioneer, di condividere conoscenze e superare le barriere con altri team di progettazione che lavorano per lo stesso obiettivo.

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).
