I thought it was a good combination of practical while being backed with data. They are big proponents of modeling out energy use with something called Manual J. They advocate for designing based on data instead of hunch which often leads to over-provisioning (less phone calls) and less efficiency. Posters also seem to be practical and focused on cost efficient solutions. This can be more rare than you think when dealing with passive house consultants or with efficiency consultants as I received many recommendations that had >= 50 year pay off times!
