passive solar homes

The ongoing debate between the merits and faults of Passive House design and passive solar design is important for those looking to build an energy-efficient home and for all enthusiasts of energy-efficient building. We've opened up the discussion to our online audience in this blog post. Please share your thoughts!
A 3-part series on sustainable comfort systems for heating and cooling homes using passive solar design, solar electric power, system controllers and newly popular heat pump technology.
Additional reinforcement is required around the garage door opening.
Scaffolding is required to access the walls to pour the concrete. Scaffolding also helps support the walls.
ICF walls must be carefully braced to prevent blowout.
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.
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.
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.
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.
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.
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.
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.
In this blog, I describe two of the first and most important design considerations -- the length and depth of the home and the layout of rooms for optimum passive solar gain.
This blog contains a detailed list of most of my initial design priorities for my net zero energy home so others may benefit from my thinking and experience on creating a passive solar, net zero energy, green home.
In this blog, I highlight the earliest decisions I had to make to create a net zero energy home: how I was going to build the foundation and walls. Thermal bridging, air tightness, insulation, cost, and greeness are all key deciders.
In this blog, my architect James Plagmann and I begin to tell the story of the construction of Dan's new net zero energy homes. Dan begins by laying the ground, defining a few terms and describing his experience in this field.
Forty years ago a trombe wall worked to store and release heat in a passive solar house. Is it obsolete in the 21st century?
Three-day workshop announcement on net zero energy homes by leading authority on energy efficiency and renewable energy, Dan Chiras. Learn how to reduce your utility bill through conservation, effriciency, & clean, affordable, renewable energy.
Enacting a law requiring builders to orient new homes toward the sun  would drastically reduce home energy costs and greenhouse gas emissions.
Dan Chiras talks about the benefits of passive solar design.
