Wind turbines don’t just collect energy. They collect attention. Environmental Building News writes in its May issue about the ways that many big green structures nowadays are incorporating “building integrated” wind power into their designs—and not always to generate much power but rather to make a loud and public statement about their greenness. EBN’s headline calls it “The Folly of Building Integrated Wind,” and for this rather staid publication that’s a pretty damning indictment.
Editor Alex Wilson, who reported the piece, doesn’t arrive at his conclusion lightly, however. In typical EBN style he come at the issue from an objective, information-driven approach that parses the pros and cons of wind turbines on buildings before concluding that “it’s usually a bad idea.”
“A green building is not green because it has [solar panels] on the roof—or a ground-source heat pump or a vegetated roof or integrated wind,” writes Wilson in his editor’s column in the same issue. “It’s green because it has an energy-conserving envelope, because it relies on natural daylighting, because it effectively controls unwanted heat gain, because it reduces dependence on automobiles, because it’s compact and resource-efficient, because it’s healthy, and because it’s stingy on water use. The heavy lifting in green design has to come from these measures, not from the window dressing. … Construction budgets are tight these days. Let’s not squander these limited budgets on high-profile visual statements.”
