Carbon emission awareness is on the rise and there is a lack of tools and references available to help designers meet important carbon emission reduction benchmarks. This paper presents a building carbon emission performance standard and outlines the methodology that was used in its creation. This standard can be used to determine carbon benchmarks emission budgets in a specific climate zone for several building types. This standard offers an easy way to determine carbon without the need to run a detailed of a computer simulation model. Not only does this standard fall in line with recent carbon initiatives it is also a performance-based approach, something that is proving to be more effective than the traditional prescriptive-based approach to standards. This standard would help an individual aim for an improved carbon use intensity in new buildings and accurately gauge an existing building's carbon emissions.
