The following three elements summarize a practical  model that is integral to the success in improving the performance of renovated buildings:

  1. Establish specific written design and construction guidelines at the project’s inception, and distribute them.
  2. Use periodic peer reviews throughout the design and construction process to compare results against the original design and construction guidelines.
  3. Implement proper startup sequence for the HVAC system to verify that the building is operating correctly before it is occupied.

The premise of this model is that at each stage in a project’s life (design, construction, and operation), crucial decisions must be made to avoid problems and control costs.. When applied properly, the incidence of building problems substantially decreases and the initial construction cost or schedule is not affected. This is made possible by eliminating many overly redundant and unnecessary building system components or procedures that often add nothing to the ultimate performance of a building.
