Net zero Hanson home
With the goal of finding a lot to build a Net Zero home that could produce enough energy to power the house and two electric cars in mind, they began the process.
The south slope of the roof is 12-12 pitch which is a 45-degree angle and optimal for solar panels at this latitude. The north slopes are down to a 9-12 pitch. By using different pitches, Sloot was able to lower the ridge of the house to allow better solar access to the solar panels on the garage.
After their first year in the home, they had – including charging their two electric cars – for an entire year.
“We used fixed [picture] windows as much as we could and strategically placed operable windows on opposite sides of the house,” for cross ventilation, said Sloot. They selected with triple-pane glass because they are . Because there are two air gaps between the three panes of glass they have a lower condensation potential from the gaps and more surfaces for coatings to help with the solar heat gain coefficient.
Advice for Future Net Zero Homeowners
Having survived the building process and finding themselves now living in their dream home, Mark and Kate have a lot of solid advice for others interested in building their own Net Zero home.
“Get a good team together,” said Mark Hanson. “Find yourself a good architect and a builder. Experience building Net [Zero] homes is not a requirement, but a willingness to learn is. And then build the team out from there.”
“Be ready to plan and spend the time to work out the details in advance,” said Kate Hanson. “And don’t be afraid to say ‘yes’ or ‘no’ or ‘I’m not sure I like that detail’ or ‘I don’t understand how that thing works, can you explain it more to me?’”.
Architect Marc Sloot also had advice for architects and builders on how to engage owners who are building their first Net Zero home.
“You really need to focus on what attributes are going to be meaningful to them,” said Sloot. “It’s important for [the homeowners] to know that it’s still, at the core, about making a beautiful, comfortable home and the Net Zero part of it is making it that much more affordable to live in.”
