The Biden administration issued new energy standards for federally funded affordable housing, which could save millions of dollars for renters and homeowners. These updated codes target insulation, windows, and HVAC systems to reduce energy costs for households with low incomes, or those who spend 8 percent of their income on energy compared with the 3 percent national average. Despite initial construction costs, tax credits and rebates are expected to offset expenses, making homes more affordable and safer while aiding climate goals.
