Gone With the Wind author Margaret Mitchell’s house was the leakiest we’ve ever tested

The #1920sMakeoverATL project is not just any ordinary house renovation project. The house has a rich history, having been occupied by the famous Gone With the Wind author Margaret Mitchell. However, it’s not just its historical significance that makes this project so special. We took on the challenge of transforming this old house into a model of energy efficiency, and we are proud to say that we succeeded.

Before the renovation, the house was tested at over 20ACH50, which meant it lost a lot of energy through air leaks. But we didn’t let that discourage us. Instead, we saw it as an opportunity to demonstrate how an old house could be transformed into a sustainable and energy-efficient home. We went to work, and after extensive testing and analysis, we identified the areas that needed improvement and devised a plan to address them.

We used the Zip System for sheathing and roof decking and sealed every seam with the Zip Liquid Flash. To ensure the sealing was done correctly, we worked closely with Build Performance Workshop and conducted multiple tests at different phases of the renovation to monitor our progress.

Our efforts paid off, and we surpassed our initial goal of meeting the Passive House Institute US (PHIUS) standard. We exceeded the required ACH50 for the Georgia Energy Code by over 1600%. Our success was not because we used fancy or expensive materials but because we focused on using the right materials and sealing processes.

We’re proud to have transformed this old house into a model of energy efficiency. But it’s not just about achieving energy efficiency. We also ensured that the house maintained its historical charm and character. The house now boasts a unique blend of historical significance and modern energy efficiency, making it a true gem in Atlanta’s housing market.

We at SawHorse Inc believe sustainable building practices are essential for a better future. We’re proud of our work with the #1920sMakeoverATL project and are committed to continuing our efforts to promote sustainable building practices. We hope this project inspires others in the industry to take on the challenge of transforming old houses into sustainable homes that are both energy-efficient and beautiful.
