How different is designing an Off Peak Cooling System from a conventional chilled water system?
TES designs need different equipment and control specifications. Those different specifications need to be developed and do have real costs. Other than that TES design is not much different from conventional chilled water design. A designers first few jobs may cost more than conventional cooling in order to develop procedures and TES specifications. Most all of the experienced TES designers say after a few projects that their TES designs cost the same as conventional cooling. There may be state and federal energy grants or rebates to help offset these costs. Some designer’s look at these added job costs as an investment in marketing to develop a niche that provides them with a competitive advantage a marketplace. Some designers will compete for a client with scope and a conventional scope; then provide a cost add for a TES design. The additional costs can be repaid with shared energy savings.
