Green Building Myth #7: Green Homes are Ugly
Average Rating: ( 0 votes)
For the last several weeks I've been describing a number of common myths about green building. This week I'll address the myth that green homes are ugly--that incorporating solar and other green features somehow compromises aesthetics. I was act... While passive solar homes 30 years ago were often way overglazed (with far too much south-facing glass), a more balanced approach today usually involves a much better-insulated building envelope so less window area is required to provide a significant fraction of solar heat. Advanced window glazings today provide a good balance between solar heat gain and resistance to heat flow (R-value). This allows windows--the right types of windows--to be installed where significant areas of glass don't make sense. In other words, better glazings allow our designs to be more flexible without sacrificing energy performance nearly as much as was once the case. Solar panels, we now know, work pretty well even if not facing exactly south or installed at an optimal pitch; we can install them flat on a roof that faces up to 45 degrees off true south and get reasonable performance out of them. In this way, those panels can be installed on a house with relatively little impact on design. Efficiency of solar-electric (photovoltaic) panels has also improved, so that a somewhat smaller area is required to produce a given amount of electricity. Other aspects of green homes--including materials used in construction--provide a full range of aesthetic choices for any taste. It used to be that if you wanted low-VOC paint your color options were limited, or if you wanted natural linoleum flooring you were limited to a grandmotherly-looking few paisley patterns. There are far more options available now. Beyond the design flexibility offered by technology advances and a larger palette of product choices to meet style preferences, we might be seeing a new aesthetic emerging. It used to be that bigger houses were seen as better by most people. Some are still in that camp, but a lot of people now prefer more compact designs. Architect Sarah Susanka helped to advance this shifting design aesthetic through her 1998 book The Not So Big House , which eloquently made the case that smaller, more carefully designed houses were more satisfying to live in and at least as attractive. Just as a Hummer is an "ugly" vehicle in my mind--because of the arrogant resource consumption it represents--I now feel the same about 4,000 square-foot suburban McMansions with their three-car attached garages and surrounded by irrigated Chem-Lawns. Knowing what I know about environmental impacts of the resource consumption required to build and operate those houses and the environmental impacts of those uniform, lush green lawns, those places just aren't attractive to me any more. What I find much more appealing is a compact, 1,400-square-foot home with a simple roofline that won't result in ice dams or drainage problems, with an enticing porch that bring homeowners outside, with solar panels cleanly integrated into the roof, and with a kitchen garden out front. This is the "timeless" design that I believe we will still find attractive in 20 or 30 years when those monster homes have become white elephants, many abandoned because of their exorbitant operating costs. Who knows, we may even come to appreciate multifamily and attached homes. I invite you to share comments on this blog.
