Construction materials: a screen of costs and CO2 intensities?

This data-file compares different construction materials, calculating the costs, the embedded energy and the embedded CO2 of different construction materials per m2 of wall space.

The file captures both capex and opex: i.e., the production of the materials and the ongoing costs associated with heating and cooling, as different materials have different thermal conductivities.

Covered materials include conventional construction materials such as concrete, cement, steel, brick, wood and glass, plus novel wood-based materials such as cross-laminated timber. Insulated wood and CLT are shown to have the lowest CO2 intensities and can be extremely cost competitive.
