Retrofitting HVAC

Retrofitting HVAC

Most HVAC systems can be retrofitted to improve reliability, reduce energy consumption, and meet new environmental standards. The first two concerns are the most common reasons for HVAC system retrofits, but environmental concerns should be considered as a part of any change.

New developments in control systems, variable-speed drives, and other equipment provide additional incentives for system retrofits. Changing codes and standards also are factors to be considered when evaluating a possible HVAC system retrofit.

GRS via the Insulpak Group have the knowledge the technical experience in designing these systems and have fully trained Green Plumbers to deliver the required system.

Considerations before retrofitting

Call us before any consideration of retrofitting. Before any retrofit work begins, managers must ensure that the system is operating as effectively as possible. This means that all of the components, including the controls, must perform their intended function. If this is not done, changes may be made that are not necessary or that may not produce the expected results.

Testing and balancing of the system should be included as part of any major retrofit project. This is where GRS can assist. In addition, managers should allow time in the engineer’s contract to review and participate in the start-up of the changes. This will help ensure that the system will function as intended. Because HVAC retrofits can be very complicated, owners and property managers must look to outside sources for help in designing a retrofit and evaluating its benefits.

The building’s HVAC contractor, who already is familiar with the system, may be able to suggest possible changes as well. However, the retrofit process must start with a thorough evaluation of the existing system, a service which many engineers are not equipped to provide. Insulpak has engineers who are familiar with retrofitting systems.

Whatever course is chosen, managers should take care to have in place a comprehensive strategy for their retrofit. Making changes one at a time without an overall master Plan may cause more problems than it solves and may defeat the intended purpose of improving the reliability and/or efficiency of the system. Once the master plan is in place, the actual work may be done in stages, as funding or time permits.

HVAC retrofits are generally undertaken to boost a system’s cost or energy efficiency. Any retrofit should take both of these factors, as well as environmental concerns, into account. Doing otherwise would be short-sighted and may not be in the best interests of the building.

Because of the complexity and range of choices in an HVAC retrofit, the owner and/or manager should look to a contractor or engineer who is experienced in working with and retrofitting existing systems.

An HVAC-system retrofit generally offers improved energy efficiency and reduced operating costs, as well as improved tenant comfort and satisfaction. Greater attention to ozone depletion and global warming may also be used in marketing an “environmentally friendly” building.
