Historic 1847 home's deep energy retrofit preserves historic windows and goes from HERS 182 to 76!

What You Need to Know


We underwent a Deep Energy Retrofit in 2010-2011. Main components of the project were putting the attic and basement outside the thermal envelope, blown in cellulose insulation, efficient hydronic heat and historic window restoration rather than replacement.

My Motivation:

Desire to improve air quality and energy efficiency, and the rebate from the utility company.

Open House Info:

Visit us during the open house from 10am-noon to learn about how we successfully survived a Deep Energy Retrofit with our marriage AND our historic windows intact! You'll learn how to avoid spending tens of thousands of dollars on replacement windows while significantly increasing energy efficiency. Visitors will receive a detailed handout documenting our project, including budget details. If you own a historic older home and want to learn about how to keep your home's integrity AND increase your efficiency, stop by!
