Georgetown University’s New Residence Hall Uses Low-Carbon Concrete

Georgetown University has announced that its 55 H Street Residence hall will be the first major construction project in Washington D.C. to use ECOpact low-carbon concrete. This concrete mix will decrease the hall’s embodied carbon by 40%, helping it to achieve its goal of surpassing LEED V4 Platinum status.

Construction of 55 H Street Residence Hall will be completed in 2022. It will house 476 students within 4,200 square feet of university space, 1,980 square feet of retail space, and multiple landscaped courtyards. To help it exceed LEED V4 Platinum status, the hall will also make use of an energy-use monitoring system, solar panels, exterior sun shading, and other energy-conscious features.

The low-carbon concrete mix is manufactured by Aggregate Industries, a member of LafargeHolcim in the US, and reduces embodied carbon by 30-100%. 

“The CO₂  savings with ECOPact are significant, and the 55 H Street project is demonstrating sustainability and performance in action,” said Chris Clow, General Manager of Ready-Mix for LafargeHolcim’s US Mid-Atlantic Region, in a statement. “As the building industry looks for ways to tackle embodied carbon in the built environment, we’re committed to offering our customers new products and solutions that build a better future.”

Clow added, “We’re seeing increased interest in specifying low-carbon products, and states, as well as municipalities, are introducing legislation around green procurement. The momentum is encouraging,”
