- How much does it cost to build a net zero home? And is a net zero home more expensive than a traditional code built home? What can you do in your custom home build to increase energy efficiency affordably?

We are giving the exact costs of how much it cost to build this net zero home we've featured on our net zero home building playlist. All of the major components of our net zero home, the mechanical, the solar panels, heating, cooling, all the assemblies and systems that make up our net zero custom home build are covered with our exact costs.
One of the number one questions we're asked as custom home builders is "How much does it cost to upgrade our home to net zero." And this is our favorite question to answer as well. We truly believe that Net Zero Homes are more affordable on a monthly basis than traditionally built, code-built homes. Building a Net Zero Home or energy efficient home is something that we think everyone should consider when building a custom home.
So, let's break down why a net zero home is actually cheaper than a traditionally built home. Throughout the video, Axe gives exact numbers of how much the upgrade cost was to achieve a net zero home build, and how much each upgrade saves in GJ of energy.

I liked your technical description that heat loss in the basement is expensive to control. But the value of added comfort is priceless. Nobody likes cold floors in the basement.
Plus you get to live in a super comfortable house and not burn as many hydrocarbons. You should also consider whether the cost of energy will be higher or lower in the future years. Net zero means you don't pay for electricity regardless of what the price is. Theoretically these benefits will add to the resale value of the house as the next owner inherits them.
Also need to consider that after 25 years your mortgage will be paid off whereas the savings from energy efficiency will continue. Furthermore, the costs of utilities will continue to inflate while time will deflate away the upfront costs of your energy efficient investments.
You need to factor in the interest of the increased payment if you carry a mortgage.
"heat rises" is a falsehood, heat moves to cold... heat will move down towards a floor that is colder than the ambient room temp, just as readily as it will move outward or upward towards relatively colder walls or ceiling or other areas
Great video! I hope to tackle a similar project in the next few years. Huge benefit knowing I'll be looking at ~$70k for a slightly smaller home.
Question for you on your numbers. Something doesn't quite add up for me. Your build (before solar) is (151-68=) 83 GJ/yr more efficient than the reference house. Your energy savings add up to (7+3+16+4+22+20+6+8+24 = ) 110GJ/yr. Seems to be a 27GJ/yr miss match. Would you be able to check on where the error came from (... including if it's my own math). Cheers.
Great video, Ill use this info in planning my first home.
Please do an update of utility costs after 3 yr,
How does triple pane casment windows perform vs triple pane eauropeon windows? Is there that much of a gap?
Per G/J saved in one year? Most ppl own homes move than 1yr… I’d run the numbers at 5&10 years as those are more realistic than 1yr.
