Improving building energy system performance by continuous commissioning

Commissioning has played important role in improved building comfort and reduced energy consumption. This article presents an advanced form of commissioning for existing buildings, called continuous commissioning (CC), which has produced energy savings comparable to those produced by the traditional audit/retrofit process at a third of the cost. It has also increased operating staff skills, reduced maintenance costs, and improved building comfort -"extras" which are not provided by usual retrofit programs. This article will present the philosophy, process, cost, and savings.
