For those gardeners who wish to grow year-round longtime MOTHER EARTH NEWS Contributing Editor and home-energy expert Dan Chiras has a solution for you: the Chinese greenhouse. Typically earth-banked into a hillside or girded by mounded earth, Chinese greenhouses bring many principles of passive-solar design into the greenhouse in order to grow using 100-percent solar radiation.
If you were to rank sustainable homes primarily based on their energy efficiency, Zero Net Energy homes would rank extremely high. They’re pretty cool — and complicated. Top U.S. home builder PulteGroup moves into the eco-friendly homes market by providing Zero Net Energy homes to the masses.
If you want to build a passive solar house, you’ll need to spend time upfront carefully considering your house plans. Here’s how one couple worked with a contractor and a designer to draw up and then finalize their small home plans with energy efficiency and lifestyle in mind.
How can you create a lush naturally abundant indoor garden year-round? With these 7 simple principles, you can create a greenhouse that is completely self-sufficient, relying only on the sun to provide all of its heating needs. Moreover, solar greenhouses can grow much more than traditional greenhouses - citrus, avocados, guava - using less energy, water and resources.
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!
Passive House standards incorporate passive solar design principles, but the two labels don’t mean the same thing. Learn about the difference between passive solar design and Passive House certification.
Never in the history of the world has there been such a high-ranking member of society to advocate passive solar design than Socrates. He felt so strongly for building with the sun in mind that he even set up a class to teach his acolytes how the finer points of putting up a passive solar house.
As the importance of solar architecture grew, the southern aspect took on great stature in Chinese life. Ancient wisdom associated the south with fire and warmth, while the north came to be synonymous with winter and somberness. The Emperor facing south therefore shuns darkness and embraces enlightenment to govern. The Chinese to this day prefer a southern orientation for housing.
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.
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.
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.
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.
The Evergreen Institute's application to provide continuing education for LEED accredited professionals has been approved by the U.S. Green Building Council. A variety of workshops meeting required standards are now available for those interested in anything from solar electricity to straw bale construction.
Today most new homes are sited without any reference to solar energy at all. A few builders are catching on, however, and making the simple adjustments necessary to turn new houses into solar collectors by adhering to the tenets of passive solar building. Learn more about how passive solar works and its benefits.
