ACV de MEP y TI en Edificios

Pregunta de investigación:

¿Cuáles son los rangos típicos de carbono incorporado (y otras medidas de impacto) para mejoras mecánicas, eléctricas, de plomería (MEP) y de inquilinos (TI)?

Sobre

Este estudio es una extensión de la Evaluación del ciclo de vida (LCA) para un proyecto de construcción con bajas emisiones de carbono. El Departamento de Calidad Ambiental de Oregón seleccionó la mecánica, la electricidad y la plomería (MEP) y la mejora de inquilinos (TI) como temas de investigación de interés para investigar porque hay muy pocos datos sobre estos impactos ambientales. Este estudio presenta estimaciones de cantidades materiales e impactos ambientales para edificios de oficinas comerciales en el noroeste del Pacífico.

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).
