Too many talk about the glamor and glory of green buildings. However, too few talk about the risks and performance problems. This presentation will examine some of the many reasons why green buildings do not always perform as expected, some misconceptions about “high performance” green and sustainable buildings, and some of the risks for designers, contractors, and manufacturers, as well as for owners and operators. Even meeting the mandatory prerequisites of USGBC LEED®, BREEAM, ASHRAE 90.1, and other certification programs are easily challenged. Most industry publications regularly feature green buildings, but do not publish the metered energy use or occupant satisfaction for comparison with the readers’ own experience. Too much reliance is placed on energy models lacking in occupant, operator, and maintainer behavioral impacts.

We will discuss the underlying factors that contribute to the misconceptions. We will analyze several case study examples of widely publicized green and sustainable buildings with metered data that show that they are not as energy-efficient, as advertised. We will also look at how to best approach overcoming these challenges.
