Buildings’ energy intensity, defined as the amount of energy used by buildings, would need to improve by 30% globally by 2030 in order to meet the Paris Climate Agreement’s aims, the key goal of which is to keep global average temperature rise to 1.5°C. While the construction sector’s energy intensity continues to improve at a 1.5 percent annual rate, the roughly 2.3 percent increase in worldwide floor area has countered some of these gains. If no scaled action is done, building-related carbon emissions are expected to increase by 2050. Read more
