A new study reveals that 89% of US single-family homes lack sufficient insulation, falling short of the 2012 International Energy Conservation Code (IECC) standards. The research, sponsored by NAIMA and conducted by ICF Consulting, highlights the significant need for insulation retrofits to improve home comfort, reduce energy costs, and minimize environmental impact. The study underscores the importance of policies encouraging home insulation and emphasizes the availability of tax credits to incentivize homeowners to make their homes more energy-efficient.
