I have found that many of the ostensibly sustainable building projects published these days are marginal in that they are expiriments and very often partial as they focus on some special technology or strategy. This is not to say that they lack value which, in my very humble opinion, is the operative word defining all things green. In fact they render this project of special interest because it is real and as such offers insight into how the various peices and parts of what we think of as responsible building might manifest. One has only to glance at the buzz words attached to the project for a protypical summary: geothermal, net zero, solar, Leed. These are all thought of as good and desirable things for the environmentally conscious homeowner. Indeed, were it not for that tricky little concept called value, many of the elements and strategies used to build this house are where I would have found myself starting had I been designing such a project. Finally though it would have become necessary for me to ask, can a house costing $700,000 really be green? If so, then to a very large percent of the world’s population “green” is a rich mans concept.
