Learn how to use it
While we've worked to make ECCHO as simple as possible, it's still a rigorous assessment of a home's performance. As such you'll need some basic knowledge before diving in.
The best place to start is our Homestar Designer course.
Throughout the seven-week course you'll have the opportunity to use the calculator extensively and learn the basics of residential energy modelling. Once completed, you'll also gain a one-year license to use the software as part of the training fee.
In addition, the Homestar Technical Manual v5.1 - Appendix B provides end-user support to use ECCHO.
