ECOPact low-carbon concrete: A turnkey solution for 9th & W

THE CHALLENGE
 

• An 11-story, mixed-use development located in Washington, D.C.’s vibrant U Corridor
• Client identified their objective to achieve LEED Gold certification early-on and was looking for building materials to help them meet their goals.
• In considering green product options, the client insisted that all the technical requirements of the project be met with no impact on performance characteristics
   

THE SOLUTION
 

• This 258,000 square foot project utilized 14,000 cubic yards of concrete, 3,000 to 10,000 psi including DYNAMax for high-strength and durability and RAPIDFORCE high-early strength for quick setting.
• The building’s design features unique angles and curves, adding complexity to the concrete and window construction.
• Holcim conducted extensive mix testing in an environment reflecting actual site conditions to demonstrate that ECOPact performance capabilities would meet client objectives.
• Holcim’s Global Warming Potential (GWP) savings calculation tool helped to illustrate the difference between ECOPact and other concrete options, convincing the client of ECOPact superiority.
• Holcim set up a Washington, D.C., plant in partnership with Climate Earth in order to generate mix-specific Environmental Product Declarations (EPDs) to substantiate the value of ECOPact.
• ECOPact low-carbon concrete provided a 22% reduction in carbon emission
  when compared to the National Ready Mix Concrete Association (NRMCA) regional average, an equivalent to the annual energy use of 118 homes.
