Townhouse Energy Efficiency

Energy-efficient townhouses benefit from shared walls, reducing heat loss. Typically 1,500–2,500 square feet, townhouses in Ontario use modern insulation and double-glazed windows, lowering heating costs ($1,500–$3,000/year). Older units may need upgrades ($5,000–$15,000) for efficiency. Compared to detached homes, shared walls save energy; compared to condos, multi-story designs may increase costs. Buyers should check Energy Star ratings and utility bills. In Ontario, rebates may offset upgrades. When touring, inspect insulation and HVAC to ensure efficiency, making townhouses a cost-effective choice for urban buyers.
