What makes a home energy efficient?

Energy-efficient homes combine insulation, air sealing, HVAC upgrades, and renewable energy. Key factors: R-value 30+ insulation, air leakage under 5 ACH50, ENERGY STAR appliances, high-performance windows (U-value 0.2-0.3), smart thermostats, and solar integration. Efficient homes reduce energy by 50-80% versus older stock, saving EUR 1,000-EUR 3,000 yearly.
