Article doesn't discuss the awful energy efficiency of modern office buildings. I've experienced it first hand. Roof is uninsulated, AC return thru ceiling, poorly insulated fresh air ducts, few thermostats, no ability to have different zones.<p>In summer anything near windows is sweltering, but the core of the building is too cool. In winter the poorly insulated fresh air ducts blast residual cold air when the heating kicks on, and the areas near windows are hard to keep warm.<p>Bah. Climate control is primitive, in both offices and houses. I dunno, maybe LEED is a solution, but I have no first-hand experience with it.
