HVAC commissioning refers to process of verifying the HVAC systems “work as the owner intended”. The initial commissioning takes place in the design, construction, and building of a facility. Often, after several years of use, owners and facilities managers need re-commissioning of their systems, this is where we can help.
Re-commissioning equipment again, is the process of making sure the HVAC equipment is working in the way that the owner intends, and the building is designed. Through a process of consulting the original design, exhaustive checks, and recommended repairs, we can re-commission the systems.
Retro-commissioning is applied to existing buildings and how to improve the efficiency of the HVAC systems. Typically, as a facility ages, the needs and equipment change. The four-step retro-commissioning process includes an analysis of the energy usage, benchmarking, prioritizing potential capital improvements, and latent design deficiencies. Through the retro-commissioning process, we can help bring your facility back to peak operating capacity.
