People often write to me via our blog for our first zero-energy house and ask what we would have done differently with the benefit of hindsight. In all, we're extremely pleased with our Seattle home, located in the Ballard neighborhood. At the time of construction, it was the first net-zero-energy house in the Seattle city limits, and it's been just perfect for our growing family. While it's hard to come up with things we'd like to change that aren't related to wishing we had a bigger budget to buy more expensive finishes and such, there was one area we wish we'd given more thought to: acoustics.
