Continuing on with Part 2 of the discussion on troubleshooting problematic HVAC systems and buildings, I want to get a little more detailed with how to grasp the big picture when starting out with problem solving an installation.
Control recommissioning in existing buildings presents an excellent opportunity to not only save energy, but to fix operational deficiencies and work with the building’s occupants to reduce complaints.
The symptoms are familiar: hot and cold complaints, higher-than-expected costs, etc. Here’s a look at how the retrocommissioning process should work to tackle these and other developments for your facility.
Last month, we tested readers on commissioning three of the many automatic temperature control (ATC) sequences of operation associated with the secondary hot water process heating system for an industrial building application.
Commissioning is a valuable tool, but according to the National Institute of Building Sciences, there is a great deal confusion as to what commissioning is, who is qualified to perform it, and the different types of commissioning agents.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
