It is helpful for project teams using the CBEO process to adopt high energy-efficiency goals.
The major drawback of the CBEO process is that it requires relatively sophisticated knowledge of building energy use patterns to achieve an accurate optimization.
These goals and commitments laid the groundwork for use of the CBEO process to cost-optimize the various efficiency options in comparison to photovoltaics.
The CBEO process produced performance targets that were adopted and helped select appropriate EEMs.
The CBEO process relies on production of both energy and cost information early in design: during concept and schematic design.
