This simple calculator will provide representative incremental costs, including labor and materials, and savings that result if you upgrade your rehab project to include selected energy efficiency measures for your size building in your climate region. This calculator is generally more accurate for 5-50 unit buildings of five stories or less, and will not work for buildings above seven stories.

Answer as many questions as you can. The more questions you answer, the more tailored the recommendations will be. If you don't know the answer to a question, leave it blank and the calculator will use average values.
