I found it interesting to watch the PBS special “10 Houses That Changed America.” In this program, the two houses that reminded me the most of our new passive solar home in southern Colorado, were the Taos Pueblo from ancient times, and the Glidehouse.
Ancient pueblo-style homes faced south for the best winter exposure to the warmth of the sun, and had thick adobe walls to help maintain indoor temperatures year round. This design provided much needed warmth in the winter, and cooler temperatures in the summer months.
Then I learned about the Glidehouse, which I had never heard of before. This is now built prefab in a factory, but was originally the architect Michelle Kaufmann’s attempt at creating a reasonably priced green home.
What did that mean to her? She wished to create an energy efficient home that maintained its indoor temperature through its unique design. With excellent insulation and many south-facing doors and windows to add solar heat in the winter, the overhanging roof on the south helps to keep the sun out in the summer. With lots of windows facing south, very little indoor lighting is needed during the day. She also installed a low-flow water system. Kaufmann’s main idea was to conserve natural resources, collaborate with nature, and create a healthier, more comfortable way to live.
Unlike our own custom-built passive solar home, the Glidehouse does not include a specially-designed direct-gain slab that collects heat during the winter months, and then releases it at night, greatly decreasing the need for additional heat. We also spent the extra dollars for spray, polyurethane foam to insulate our outside walls, providing the best R-value for both winter and summer.
I am happy to see more Americans who are concerned about energy efficiency in their living situation, not just to save money, but to live more in harmony with the earth. I love living so close to nature, and waking up to see bunnies coming up to my sliding door to look in in the morning.
