Environmental performance of buildings - Carbon metric of a building - Use stage

This document provides a method for quantifying the carbon emissions associated with the operational phase of buildings. It outlines procedures for measuring, calculating, and reporting greenhouse gas emissions resulting from energy use, water consumption, and other activities throughout the lifecycle of a building. The standard supports the assessment of environmental performance by offering a consistent approach to carbon accounting, enabling stakeholders to make informed decisions regarding energy efficiency and sustainability. It includes guidelines for data collection, emission factors, and the application of measurement techniques relevant to building operations. The scope encompasses various types of buildings and their associated systems, promoting a comprehensive understanding of carbon impacts during the use phase. This approach facilitates the comparison of performance across different buildings and supports the development of strategies to reduce environmental impacts.
