It's how solar energy is more affordable than we may realize.
The invention of clear window glass allowed the ancient Romans to trap solar energy to enhance their gardening techniques to grow vegetables out of season and exotic non-native plants in Rome. A thousand years later, empire builders in Europe rediscovered the trapping of solar heat with clear window glass so they as well could enjoy the foreign plants in their own back yard and grow native vegetables throughout the year.
Alternative energy has become a hot topic in recent years as we try and work towards more sustainable resources. Whether we'll get there or not remains to be seen.
To see how much solar heat could be trapped by glass, Horace de Saussure, in 1767 built a solar hot box that consisted of several glass sheets covering an insulated box. Solar heat accumulated in the solar hot box, reaching temperatures far above the boiling point of water

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.
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.
New investment in clean energy reached $243 billion last year, driven by soaring activity in China, offshore wind and European rooftop photovoltaics
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 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.
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.
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.
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.
