Passive house: 65° in winter with no heater 😱

It's been in the mid to high 30s the last few days here in the Denver, Colorado area. Our #passivehouse has been staying at around 65 - 69 with no heater. Our mini-split system is needing to be repaired so we turned it off. Even with it getting down into the teens at night (17 degree last night) the house is still staying incredibly comfortable.

There isn't enough info out there about passive houses. So many competing design theories. Really appreciate the performance/quality of living details. Good looking house

Great and informative video.
Nice house by the way!
Kind of Scandinavian look.

This should definitely be featured on the build show

a solar collector for warm water would really supplement the passive solar heating you have going now with the windows. a neighbor of mine has a system like that that uses glycol (antifreeze) as the medium. on partially cloudy days he still gets temps of 65C coming in and in the neighborhood of high 80's to low 90's on clear sunny days. a large water reservoir to hold the warm water for release at night would be the ticket to really cut down your heating bill the only energy the system requires is an electric circulation pump to move the water

Performing well it seems. Curious about the glossy paint on walls and ceilings.

I personally would find 65F too cold in the winter. I'm spoiled with radiator heat in Chicago and the "coldest" my apartment gets is 74F. When the heat kicks on it can get to to 78/79. On the coldest days it's not unusual for my temperature reader to get to 81. I turn the heat down at night and crack a window.

I definitely see the value in passive house design. At the very least incorporating this design can cut energy consumption if people choose to have AC and heat. I'd probably want radiator heat if cost wasn't a factor.

Great efficiency, seems like you could just bake a loaf of bread and the residual heat would warm your house

How much extra did this home cost than a regular home? Guessing at least 35% more which would be around 150k-200k? Then how many years would the payback period be? 30? Yes in the long run the house will save enough energy to make it worth it, but considering most home owners only live in a house for 11 years, they wont realize the energy savings.

Which type of insulation did you use? Nice video.

[kssawyer]

What brand of windows did you use? I'm having problems choosing.

So there is no heater whatsoever in your house?
