Most conventional paints and coatings emit Volatile Organic Compounds (VOCs), which can contribute to poor indoor air quality as well as to smog. This overview includes a link to a product listing of healthier low-VOC, zero-VOC, and natural paints.
To build a net zero energy home, you'll need to design for passive gain. That requires a shallower footprint to ensure that the low-angled winter sun can enter and heat each room.
Insulation under the slab -- and lots of it -- is vital for the performance of a net zero energy home. So is the footprint. You can make the most of passive solar by creating a longer, narrower house in which each room is heated by the sun.
Be sure to install under-the-footing conduit to run electrical and water pipes, including sewer. I like to run pipes and wire under the foot to prevent penetrating the band joist or the foundation to create a more airtight, water tight home.
Don't forget to budget in the cost of deeper excavation and add $1000 to $2000 as a budget contingecy in case you run into bedrock.
Insulating concrete forms are an excellent choice for foundations for passive solar, net zero energy homes. They create a highly insulated, air-tight foundation, so essential for extremely high energy performance.
ICFs are not the most environmentally friendly green building product, but result in super energy efficient home, and offer many other benefits, that offset their origin from petrochemicals.
ICF walls must be carefully braced to prevent blowout.
Creating a net zero energy home requires that we eliminate all thermal bridging loss -- heat movement into and out of a building. All this starts in the basement.
Scaffolding is required to access the walls to pour the concrete. Scaffolding also helps support the walls.
Additional reinforcement is required around the garage door opening.
