Fantastic course, really enjoying the blend of breadth and depth!

My knowledge in heat transfer and building science principles is good. However, this week I learned the intricacies of integrating IEQ into the equation.

I am becoming more and more interested in this topic of exergy efficiency, mostly inspired by your graph and the readings in the course. Thanks!

Content is fantastic.

Overall, this is fantastic and timely material, I'm learning a lot and am thrilled I signed up.

I'm happy to be taking a class from you.

Thank you very much for accumulating all of this knowledge over the years and sharing it with us.

Online registration is now open for the March 2015 course.

If you have any questions about the course you can talk with us directly at our Linked-In discussion group or though the HeatSpring Learning Institute.
