In this episode:
Kevin arrives as framing the new addition is just underway.
Jeff shows Kevin how he’s framing this net-zero house with studs placed farther apart than the traditional practice, decreasing the amount thermal bridges will allow for heat to escape. Kevin helps him build a wall with insulated headers.
They also frame the corners differently to allow for more insulation.
Richard demonstrates heat loss and gain to design a balanced HVAC system. With a model of the new project house, he shows what sun exposure and ventilation can do to a building.
He and Donald take a trip to the International Builders’ Show in Orlando, Florida to see the latest technology.
Now that the project house is opened up inside, Jeff points out a plumbing error made long ago.
Electrician Ben Giles shows Kevin old knob-and-tube wiring that was still in use until demolition started. He will soon strip out all the old wiring.
