As a manager for a Community Action Agency, I direct most staff members towards this course to get a better understanding of ASHRAE requirements within the WAP program

Being new to the Ventilation industry, this course provided the knowledge to have meaningful conversations with others more experienced. Also, it brought a real awareness of the health risks caused by stale indoor air and straightforward solutions to improve our quality of life.

I have been in weatherization for over 2 1/2 yrs and have been designing and installing ventilation systems and i thought i needed to learn more. This was the perfect course for me since i have already been using the free red calc tools. It helped me learn more of the tools that i did not know would be a great help in my work.

I'm very pleased to take this important course. I haven't been doing an Energy Weatherization Audit for few years and it was to the point and refreshing. The website is updated and all those new tools are so awesome. Hopefully, I will make your website too busy for this year and years to come.

Awesome class learned a lot and found much more information that I needed and clarified lots of questions I had. The online tools are new to me so having them is very helpful. Thank you.
