SEC TION 14 | EC3 TOOL

EMBODIED CARBON IN CONSTRUCTION CALCULATOR (EC3)

IMMIGRANT MUSEUM I WAS ABLE TO PASS THE TARGETED GOAL OF 34% AND ACHIEVED 46% EMBODIED CARBON REDUCTION BY SELECTING THE RIGHT MATERIALS.

The EC3 tool provides the opportunity to access the information on the embodied carbon built into building materials.

For the precedent I chose to analyse structural and foundation systems of my Studio 4 project, which is a museum located in Boston, MA. Gross Floor Area: 110,260 ft2 Height: 80ft Weight: 3.67M lbs EC Total (Conservative): 1.16M kgCO2e EC Total (Achievable): 769k kgCO2e EC Total (Realized): 626k kgCO2e

I calculated the amount of concrete and rebar needed for foundation piles and counted how many linear feet of wide flanges and hollow metal is in structure.

Through the EC3 tool I selected the materials that had the best balance between quality/availability/distance-toproject and embodied carbon amount.

DEMO BUILDING A IMMIGRANT MUSEUM EMBODIED CARBON REDUCTION WAS GREATER THAN DEMO BUILDING A BY 3% OF BUILDING TOTAL.

Demo Building A was over achievable targets for steel structure, but was able to keep the EC of Concrete way below the target. The selection of low Embodied Carbon materials allowed to perform 51% total building reduction from the Conservative EC Total. Gross Floor Area: 256,000 ft2 Height: 60 ft Weight: 20M lbs EC Total (Conservative): 4.18M kgCO2e EC Total (Achievable): 2.45M kgCO2e EC Total (Realized): 2.65M kgCO2e
