NYC Geothermal Heat Pump Manual sets a Lofty Goal
In August of 2002, the City of New York Department of Design and Construction published a Manual guiding engineers through the design and installation of geothermal heat pump systems in their city. This manual covered the basics of geothermal heat pump designs, the intricacies of the complicated NYC geology, and the intricacies of the complicated NYC permitting process. As such it was a positive step by a government agency to facilitate the adoption of high-efficiency building systems. And it was a somewhat counter-intuitive move, since ground-loop heat-pump systems are often considered prohibitive in dense urban areas.
This manual sets an intriguing example for other local or state governments--especially ones where the underlying geology of their areas of jurisdiction are complicated or where strict building or energy codes exist. In cities like Seattle, where both are the case, a similar manual would be of great utility to local designers.

There is probably much of benefit to any designer working in areas of jumbled glacial deposits as are found in the Puget Sound region.
