This Heavily Altered Wood, Stronger Than Aluminum, Cools Passively
This ultimately makes the material much stronger than wood (though the researchers don’t compare its strength to that of pressure-treated lumber, which is also stronger than untreated wood). As a result, the material is really bad at absorbing sunlight, and thus it doesn’t capture the heat in the same way regular wood does. The researchers estimate that covering an apartment building with the treated wood could save about 35 percent of the energy used for cooling.
