The last 30-years have seen some significant changes in the technologies and techniques used in designing and constructing new commercial buildings. While this has included significant strides in the energy efficiency of lighting systems, glazing, insulation, and HVAC equipment efficiencies, this has not translated to consistently high performing buildings.
Typical new buildings are using nearly the same energy use per square foot as buildings built in the 1980s. This presentation seeks to explain why energy use has not dropped dramatically along with the improvements to lighting and building envelope. To do this we will present lessons from our experience auditing local buildings. From these case studies of real buildings we will pull out the key things that need to change to deliver highly energy efficient buildings.
