How to Renovate a Home in Dallas- the RIGHT Way

Dear Corbett-
I am not a contractor, but a residential homeowner that has become increasingly interested in owning (and taking a part in creating) a high performance building. After going through several series of podcasts, I ran across yours, and immediately loved it because you went into greater detail about the things that I want to learn about; so I want to thank you for the podcast.
Onto my situation.... I am looking to buy an older (1940's) home that has no hvac, next to no insulation, and needs a good deal of work; but I believe it has the best potential for making a high performance home.... a blank canvas.
What I am having trouble with is finding the local rock stars that can really help me make my house as efficient and comfortable as possible with my given budget. Do you know of any really good people in the Dallas area that could get me on the right track? Thanks again for putting out all the info!

Thanks for reaching out, Derek! I'm always happy to help, and I think the home you're considering is a GREAT OPPORTUNITY. A blank canvas is much easier to paint on, and when a house is fully 'finished' and has been renovated, it just means you'll have to dig harder and deeper to find and fix the issues that are lurking under the surface.
I'll hook you up privately with a few of my own black belts who are part of Fall Fast Track, but I also want you to know that when we take this show on the road next year for the Proof Is Possible Tour, we'll be creating a directory of pros who pledge to deliver guaranteed results across the U.S.!  Stay tuned here for further developments on that front, and keep in touch about your high performance home renovation!
Looking Forward,
Corbett

How to Master the Multi-family Blower Door Test

Hello Corbett,
A need to run a Blower Door test at a 3 house complex here in Greece. The houses are in the row, this means that normally I should have three Blower door devices, in order to measure the house in the middle. But I have only one Blower Door!
Additionally, I will need to hand over a written document (report), in order to certify the construction to the Passive House Institute. Do you have any suggestions?
Best and thanks in advance,
Stefanos

Hey Stefanos-
Great question! You do not, in fact, need multiple blower doors, because you actually want to include the unit-to-unit air leakage.  The measurement of all uncontrolled air leakage to outdoors and to other townhouses is a valuable one, and it should be the goal especially when building to Passive House (or PassivHaus) standards.  Watch this video for a visual explanation:

I Turned My A/C Off All Day at 106 Degrees

Dear Corbett:

I thought I would send this your way.  I live in the Central Valley of California.  Yesterday it reached 106 degrees.  I did an experiment with my house.  My 1,883 sq./ft. house had a deep energy upgrade over three years ago.  The heating and cooling unit is a 2 stage/2 ton heat pump with no back-up heat.  The second stage of cooling is disconnected so I am cooling with 1.4 tons.  That is one ton for every 1,345 sq./ft.

Yesterday morning I left the house at 7:40 am.  It was 75 degrees in the house and 75 degrees outside.  I closed all of the blinds, turned the HRV off and turned the Heat Pump off.  In other words, I let the house float.  It got up to 106 degrees in Stockton yesterday.  Luci my bride got home at 5:40 in the afternoon and the house was 78 degrees.  She turned the thermostat back on and it brought the temp back to 75 in 30 minutes.

This stuff really works.
Keep up the GREAT work;
Dick Rome

Dear Dick-

You are awesome. I'm not sure I know many other home performance experts who have fixed their own homes- most of our families have to suffer at home while we help other people get comfortable. Thanks so much for sharing the good word!

Infrared Thermal Photo Art! Nerd-Out!

I now carry a tiny infrared thermal camera with me everywhere I go, and I've decided to make it my contribution to humanity. I got so tired of washing dishes and being nice- this will be much easier, as contributions go!

The sun is more than 248 degrees. Get out!

I literally am such a nerd about this that I point it at trees, the floor, anything that might be awesome. 

The floor. With a spill on it! 

Trees! 

Feet! 

Infrared is not an X-ray, you can't really see through anything, but you can see temperature changes behind objects, which is also technically a superpower.

People look pretty cool under infrared, as long as you don't look at their faces, which look terrifying. 

The crowd at an Indigo Girls concert

What I mainly use my infrared camera for, though, is buildings. You can't hide anything in construction anymore, thanks to tools like this. 

One brick wall: old brick on the left, new brick on the right. Very different heat signatures!

The camera I got is called the Flir ONE, and it mates with my iPhone 5 to make my pocket bulge with infrared awesomeness! For $250, I recommend it to anyone who likes having an easy superpower.
