A Few Photos from Day 1 of Our HERS Rater Class

Our 2 Blower Door Setup, With One Minneapolis And One Retrotec System

Yesterday we began our latest HERS rater class, training a new group of home energy raters. We have 11 students this time, mostly from Georgia but also one from Virginia and one from Tennessee. We spent the first half of the day in the classroom and then went out into the field the whole afternoon. Here are a few photos of the day.

We’ve got a Blower Door from Retrotec and a Minneapolis system from The Energy Conservatory.

One of the activities our HERS rater students did was to measure the classroom & calculate the areas & volume.

The students measured the classroom and calculated the areas and volume.

After lunch we visited two houses. The first was a new home under construction that’s going for LEED for Homes certification (not sure which level). Called the Midtown Green House, it’s being built by my friend and former employer Matt Hoots of SawHorse here in Atlanta. As you can see it’s got a lot of open-cell spray foam insulation (Icynene in this case).

You can see two of the many green features of this house in the photo above – a manifold distribution plumbing system and Superior Wall construction for the basement walls.

Here’s the class in front of the Midtown Green House, minus our two home inspector students who were probably checking out the house for code issues.

    a primer application on drywall and slab of ThermaCote on blower door test reportedly closed the equivalent of 21 square inch hole in targeted ‘tight envelope’ constructed housing at Ft Drum. How do I share this important letter with you? Please Email me before my head explodes…

    Thomas, 21 square inches corresponds to about 100 cfm50 in a Blower Door test. Depending on what the total cfm50 was, that variation may well be in the noise. Primer on drywall or a slab will have little effect on Blower Door results.
