HVAC of the Future | The Jamestown Net-Zero House

Coming up on This Old House 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.
