Dan, of Flack and Kurtz, in New York City. Da</FONT></SPAN><SPAN style="COLOR: #1f1f1f; FONT-FAMILY: 'Arial','sans-serif'"><FONT size=3>n is both an architect and engineer, and a leading expert on energy use in buildings. He told us that some back-of-the-envelope calculations he had done suggested that an average office building in this country accounts for more energy use getting people to and from the building (commuting) than the building itself uses for operations. This was a shocker--a real slap-in-the-face wake-up call. In </FONT><A href="http://www.buildinggreen.com/"><SPAN style="COLOR: #384355"><FONT size=3>Environmental Building News</FONT></SPAN></A><FONT size=3>, I set out to do somewhat more sophisticated calculations--mining statistics on commuting distance, modes of commuting, vehicle miles-per-gallon, and square footage used per employee--to be able to compute the energy use per square foot of office building per year (the same metric used in reporting operating energy use by buildings). This analysis allowed me to compare the operating energy use of a building with this new metric of "transportation energy intensity." And, indeed, based on the statistic I found, Dan was correct.<STRONG><SPAN style="FONT-FAMILY: 'Arial','sans-serif'"> We use more energy getting to and from commercial office buildings than those buildings use for heating, cooling, lighting, and such.</SPAN></STRONG></FONT></SPAN></EM></P>
