Buildings are responsible for 40% of the total amount of energy needed (US, EU). Mandating better air tightness (<1 ACH@50) and raising insulation levels would go a long way to reducing that. Residentially, you can built a 5000 square foot (500 sq. m) home that needs only 1500W (1.5 kW)—basically a hair dyer—to heat/cool: * https://www.youtube.com/watch?v=_vul4vMFdkA Using an HRV/ERV with an air filter per ASHRAE 62.1 and 62.2 gives you very good air quality. |
