Energy Positive Homes, Inc. in Mondovi, Wisconsin will work with builders in designing and constructing homes that create more energy than they consume. Utilizing a 3D printer, we will “print” all the forms for the walls using lightweight concrete.
This better building technique can result in huge savings that will be used for:
With 3D printing building techniques, houses will be fire, flood, hurricane, and tornado resistant. Homeowners will also enjoy the advantage of not having heat or electric bills. Likewise, they will have the ability to charge an electric car parked in the garage for free.
Additionally, they should use 70% to 80% less water, as these homes will be utilizing atomizers in the showers and faucets. Thanks to an Aquaponics system, homeowners have the option to grow organic food in solariums in half the time it usually takes for the plants to grow.
These homes will be priced around new construction prices, but be better in nearly every conceivable way.
After building the first prototypes, we will be partnering with builders to construct spec homes that are move-in ready. Our goal is to create a market for better-built homes with a net cost of hundreds of dollars less per month for homeowners.
Homes built in areas with a Feed-In Tariff program can produce an income from the excess electricity they create, possibly reducing the net cost of the ownership even further. Special "Energy Efficient Mortgages" (EEM's) are available now in some areas for financing homes with more efficiencies.
According to the latest research, there are between 500,000 to 600,000 new homes built in the U.S. each year. Right now, nearly all of them are traditional wood construction.
All of that is about to change, though. Imagine that you are choosing between two homes for sale in the same general area. They have similar finished square footage, layout, aesthetics, and price. However, ONE home has no heat or electric bills, a much smaller water/sewer bill, and can also grow organic food in a solarium helping reduce your food costs.
It is resistant to fire, natural disasters, soundproof, and can also charge your electric car every time you park in the garage.
Which would you choose?
The net cost of owning an Energy Positive Home can be $500 to $1,000 less per month than a typical new home,
and potentially healthier as well if your choose to grow some organic food in your solarium. All for about the same construction cost! Energy Positive Homes are better in every conceivable way.
We believe that new home buyers will drive this change in home construction. A $300,000 new home built with a 3D printer should save around $45,000 through the following:
Additional savings may also be created through reduced market times, as they are likely to have buyers before their certificates of occupancy are issued. Likewise, they may be auctioned off for a much higher profit than wood construction alternatives.
The average cost of a home west of the Rocky Mountains is about $110 per square foot with an average size of 2,649 square feet. Multiplying that results in a $291,390 price for an average new home in that area.
About 80% of the new houses being built in that area are spec homes, or houses built without a specific buyer in mind. We believe that spec home builders will rush into this new construction method after prototypes are built, and “the two similar homes” scenario detailed above will begin to happen in larger cities in the west.
Printing the forms for the walls from cement requires only four people continuously working until printing is done. One would operate the computer while the three others will place the conduit, pipes, bucks,.... where needed during printing. Additionally, they will take care of the concrete mixing for the forms. The inner walls will be filled by truck loads.
A printer should be able to print the forms in two or three days, with a day of setup and another day for takedown. Printing homes in a development may go faster, since there will be less transportation of materials.
This process could be sped up to building two houses a week with two frame setups per printer. The printer can disconnect from one frame and be transported to the second one that has already been set up.
