The goal of these innovative systems is to save energy and to provide equal or better indoor environmental quality. Too often, however, theoretical gains are not realized in the final product. The reasons span from design and specification through manufacturing, installation, operation, and maintenance. The practice of commissioning is poised to address all of these aspects, however, it needs to be focused more intently when innovative systems are involved.
Market forces with a relatively minor regulatory element largely drive the evolution of standard building equipment and systems. In order to compete, manufacturers and engineers have had to provide reliable products with the lowest possible first cost and low operating cost.
