""You can build with natural stone in a way that saves about 90% of the carbon emissions compared to if you are building with steel or reinforced concrete. "Construction is a huge emitter of carbon and the government wants to build lots of homes so we need to find ways that don't damage the planet so much. "This is one solution that we are testing.""
"The Design Museum estimated that an equivalent structure to the stone house, but using a steel frame with a brick facade, would emit 262,870kg of carbon dioxide (CO2). A frame made of reinforced concrete with a brick facade would emit 252,633kg of CO2. The Stone Demonstrator produces only 6,443kg of CO2 less than 3% of the others. The stone is cut from quarries and in this case was shaped and designed by The Stonemasonry Company in Rutland."
A Stone Demonstrator structure in Earls Court is constructed primarily from natural stone to test lower-carbon alternatives to conventional materials. Government funding supports the project to encourage builders to switch to stone as a building material. Estimated life-cycle emissions for equivalent steel-frame and reinforced-concrete-frame structures are about 262,870kg and 252,633kg of CO2 respectively, while the stone structure produces only 6,443kg of CO2, under 3% of the alternatives. The stone was cut from quarries and shaped by The Stonemasonry Company in Rutland. Substantial prior investment in fossil-fuel, concrete and steel industries presents adoption challenges.
