Too many talk about the glamor and glory of green buildings as well as the higher income for designers, contractors, and product manufacturers.  However, too few talk about the risks and performance problems.  This presentation will examine some of the 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 owners and operators.  Even meeting the mandatory prerequisites of USGBC LEED®, BREEAM, ASHRAE 90.1, and other certification programs is easily challenged.  Most industry publications feature green buildings, but do not publish the metered energy use or occupant satisfaction for comparison with the readers’ own experience.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.

Actual experience with metered energy data from green and sustainable buildings shows that most do have performance gaps as do comparable traditional new buildings.  A key reason is the complexity that is designed and installed to achieve more points and higher expectations, but rarely performs as modeled or advertised.  Too much enclosure insulation is another reason.  Most building operators are not qualified to understand these complex systems and their intended functionality.  Even many contractors have little or no training or experience with installing and maintaining these systems.  This presentation will provide case study examples of widely publicized green and sustainable buildings with metered data that shows they are not energy efficient
