Twenty or more years ago, mechanical engineers who were designing systems for communications, manufacturing, office, and other facilities could not have foreseen the impact that advances in technology and adaptive reuse of these facilities would have on as-built mechanical systems. Yet today, owners and engineers alike are dealing with the problems resulting from piecemeal mechanical systems upgrades to accommodate new technology and changes in building use over the years; problems that include high energy, O&M, and repair costs, as well as decreased reliability.
Many are finding that the solution, overall re-engineering and recommissioning of the system, can be implemented using a performance service provider (PSP). This approach offers the guaranteed maximum pricing, savings, and return on investment needed to justify the capital expense.
