February Chapter Meeting – Intro to MEP 2040

Event Details

Buildings account for approximately 40% of the carbon emissions in the world today which includes the embodied carbon of materials and the operational carbon needed to operate them.  As part of the efforts to decarbonize buildings, understanding both the embodied carbon and the operational carbon of different building systems is paramount to achieving significant reductions in carbon in the built environment.

While initial studies exploring the embodied carbon of buildings focused on the structure and façade as the primary “consumers” of embodied carbon, emerging research has shown mechanical, electrical, and plumbing systems make up a much larger portion of embodied carbon when considering the total lifecycle of the building.

Since no building system is designed is optimized by being considered independent of the other building system (e.g. the building envelope and lighting systems impact the HVAC systems), methods for assessing and reporting the embodied and operational impact of MEP systems is essential to reach a fully decarbonized building.

The MEP 2040 commitment is one way MEP professionals can voluntarily calculate the impact of their designs on both embodied carbon and operational carbon.

This session will discuss multiple ways to calculate embodied carbon, nuances of estimating operational carbon, and identify some of the “low-hanging fruit” in reducing both embodied carbon and operational carbon in buildings
