Overview
By using EnergyWiseTools.com, you agree to the terms described on this page. These terms exist to be clear about what this site is — an independent educational resource — and what it is not: a licensed engineering service, a contractor referral platform, or a guarantee of any specific outcome.
Last updated: May 2026
Calculator Disclaimer
Important: The calculators on this site produce estimates for educational purposes only. Results are based on established building science formulas and generalized assumptions. They are not a guarantee of actual savings, costs, or performance. Your real-world results will vary based on your home's specific construction, local climate, utility rates, contractor quality, and other factors.
The tools on this site are designed to help homeowners understand the relative impact of home energy improvements — not to provide engineering calculations, certified energy ratings, or binding cost estimates. Before making any significant home improvement investment, you should consult with a licensed, qualified contractor or certified building performance professional in your area.
A BPI-certified contractor or certified home energy rater can perform an on-site assessment that takes your home's actual conditions into account. The results from tools on this site should be used as a starting point for that conversation — not a replacement for it.
Educational Use Only
All content on EnergyWiseTools.com — including calculator tools, blog articles, and explanatory text — is provided for general educational and informational purposes only. Nothing on this site constitutes professional engineering advice, licensed contractor recommendations, legal advice, or financial advice.
The information presented reflects general building science principles and field experience. It is not tailored to any individual home, local building code, utility program, or specific product or contractor. Local conditions, building codes, and utility incentive programs vary significantly and may affect outcomes.
No Warranty
EnergyWiseTools.com is provided "as is" without any warranty, express or implied. The site owner makes no representations or warranties regarding the accuracy, completeness, or reliability of any calculator result, article, or other content on this site.
While every effort is made to ensure the tools are grounded in sound building science, errors in formulas, assumptions, or data are possible. The site owner reserves the right to correct or update any content at any time without notice.
