The winners of the 4th Global Holcim Awards for Sustainable Construction have been decided—the trophies and $350,000 prize money go to projects in Colombia, Sri Lanka, and the U.S.
All three prizes recognize architectural interventions that deliver tangible benefits to local communities: Turning a decommissioned water reservoir into a park in Medellín, rebuilding social fabric through a community library in Ambepussa following Sri Lanka’s civil war, and creating public zones and flood-protection for the island of Manhattan.

A new study presses for measuring embodied carbon in industrial buildings
The embodied carbon (EC) intensity in core and shell industrial buildings in the U.S. averages 23.0 kilograms per sf, according to a recent analysis of 26 whole building life-cycle assessments. That means a 300,000-sf warehouse would emit 6,890 megatons of carbon over its lifespan, or the equivalent of the carbon emitted by 1,530 gas-powered cars driven for one year. Those sobering estimates come from a new benchmark study, “Embodied Carbon U.S. Industrial Real Estate.”
