Ah, Eichler homes — a truly California mix of indoor and outdoor living. But sometimes this comes at the price of dis-comfort. Many Eichler owners complain of being too hot in the summer as the sun bears down on their patio or atrium. And too cold in the winter as all that glass conducts the warm air out.
Typical home improvement suggestions to increase comfort are to add insulation in the walls and replace your single-pane windows with double-pane. Both will save energy, but lack an element of “fun” we crave. And the expense! Here are a few different ideas:
Close off the atrium or patio.
Some Eichlers wrap around their open courtyard. It’s a simple matter to add the final wall and some kind of roof covering. The roof area can be covered with an innovative skylight option. I’m a big fan of putting skylights over the atrium, because it makes the area useful during the rainy winter months, so we get more use out of the whole house. We installed a Rollamatic Roof. Our energy efficiency tests show that it doesn’t leak warm air at all. This means the glass windows facing the patio or atrium no longer conducts warm air to the outside, saving energy and money.
Oh, and the courtyard floor has now moved indoors. It can be heated with a simple add-on such as Warmfloor™.
Add awnings for shade.
A recent study showed that shading windows on the south and west can substantially reduce air conditioning costs. While our air conditioning days are minimal, homeowners can increase comfort by shading windows and patio areas in the summer. East-facing patios, for example, can heat up in the morning and release that heat all day long, raising the house temperature in the afternoon when the sun is blazing down from the west.
Sale shades provide wonderful trapezoidal shapes for shade, a style that fits with the contemporary Eichler look. Sunset Magazine even recently featured an Eichler with a sail shade.
Add blinds to your single pane windows.
Cheaper than replacing all those famous Eichler windows with double-pane, blinds can help reduce heat gain in the summer and heat loss in the winter. Their effectiveness will depend on your lifestyle. Here are reasons that blinds may or may not work for you.
First, blinds reduce heat gain and heat loss when they are closed. But, as Eichler owners, we like our open indoor/outdoor feeling. So, blinds depend on the good habit of actually pulling them down. Will you really do it?
Second, blinds are an imperfect seal. They let hot air in, and cold air out. They will reduce heat transfer, but not as effectively as a double-paned window. Will you mind? If blinds are a solution for some of your windows, look for those that have R values (insulation factors) of 2 or more.
Match your choice of blind to your purpose. Some styles are optimized to save heat in the winter. Other styles are optimized to provide shade in the summer. There are even shading blinds that you can look through, keeping the best of both worlds — Eichler’s feel of outdoor living while cooling the house in the summer.
I love living in my Eichler, but I want to save energy too. Let’s keep looking for fun ways increase comfort.
