The is a springtime view of my straw bale house that is featured in the “Building With Awareness: The Construction of a Hybrid Home” DVD and book. Click the image for a larger view.

While riding my recumbent bicycle home from the office the other day, I was caught by the reflections in my neighbor’s flooded field. They recently planted a citrus orchard and garden and were irrigating late in the day. I grabbed my camera to capture the soft glow of a typical New Mexico sunset.

When living in a straw bale home, Spring is the time to remove the insulation panels from the skylights (to prevent heat loss in winter) and to turn off the pilot light of the backup radiant-floor heating system (despite some nights that still dip into the 30’s, the home does not need backup heat at this time of year). The rainwater cistern is 80% full due to recent spring rains. This will supply enough non-potable water until the summer monsoon season begins in a few months. The photovoltaic electrical system generates more electricity in the Spring and Fall due to the fixed angle of the PV panels to the sun. It is also time to put the window screens back up as they are removed every Fall to maximize the amount of heat entering the windows from the low-angled winter sun.

The warm earthen tones of the home’s walls come from the mud plaster finish. The small workshop to the right is made of adobe bricks. These materials are very green as they come from the earth itself—with minimal processing.

If you would like to see how this green home was built, pick up a copy of the “Building With Awareness” DVD video and book combo. It is available at a bookstore near you and online. “Building With Awareness” is beautifully photographed and covers the complete design and construction process of building green with straw bale, adobe, and other natural materials. The purchase of our DVD video and book helps to support this blog and website on green building.

Photovoltaic panels generate clean power by converting sunlight into electricity. This article will talk about the actual—verses the rated—power output of photovoltaic panels. Do not assume that a PV panel rated at 170 watts of power will actually give you that amount. It will probably be closer to 150 watts per panel. Because of the difference, care must be used when sizing the system for your electrical needs. Otherwise, you may find that you are generating less power than you need.

Designing a photovoltaic system for your green home starts with using energy efficient appliances and lighting inside the house. My rule of thumb is that it is cheaper to buy a new EnergyStar-rated refrigerator for under $1,000 than to spend an extra $2,000 on photovoltaic (PV) panels to power an old, inefficient refrigerator. The same goes for other appliances—particularly those that get a lot of daily use such as televisions.

The photovoltaic system for my small straw bale home (featured on the BuildingWithAwareness.com website and DVD video) cost around $12,000 in equipment. Without carefully choosing the most efficient appliances and  lighting, the cost would have been dramatically higher.  (more…)

This Japanese structure is very simple, yet very elegent in its simplicity. Even without the details of windows and doors, there is a warmth to the building. The earth plaster walls have aged to a watercolor-like patina. The patterns come from mud that was mixed with rapeseed oil (a vegetable oil more commonly known as canola oil).  Materials such as this are in beautiful contrast to the monolithic look of stucco or paint in that they create harmonious variations in color and texture.

The design principles used in this structure can be incorporated into home design. They are not hard rules, but something that can be drawn upon to add visual interest. By being able to evaluate what works and what does not work in a particular design, it will be easier to make the changes that are required to fix the problem. The owner/builder should be very involved in the structure’s design, instead of just turning it over to a “professional”. This goes for both green building design principles (for overall energy efficiency) and the aesthetic design. Being aware in all of the various design options is what I call ‘building with awareness” (hence the title of my book and DVD).

For simplicity, I will break the visual design of of a building into two parts. First, there is the overall physical form which is the shape of the building. The second part would be the color, texture, and surface treatments within the major shapes. An analogy would be the overall shape of a tree that is enhanced with the color and texture of the bark and leaves. (more…)

This article will show how to attach commercially available solar panel mounting brackets to a corrugated metal roof that lacked flat surfaces. In the photo above, a ladder was used to slide the PV panels to the roof.

Photovoltaic (PV) panels produce all of the electricity for this straw bale hybrid home from sunlight. All of the PV panels are permanently attached to the south facing pitched roof.  Standing-seam metal roofs are partially flat, so mounting a rack is not a problem.  The roof on my house is corrugated metal and therefore has no flat surfaces for the aluminum mounting brackets to seat.  A stout connection is essential for the photovoltaic panels to survive high wind loads and to create a waterproof seal where the bolts penetrate the roof surface. What we needed was a mounting platform that both comformed to the convolutions of the metal roof and also had a flat surface for the foot bracket to contact.

Here is how we solved the problem. (more…)
