HVAC EBCx Retrocommissioning Commissioning Commercial Office Classes Existing Buildings

For the past four months, I've spent a day a month at the Pacific Energy Center in an intensive retrocommissioning class. For those not familiar with retrocommissioning, it's essentially a treasure hunt for poorly performing systems in existing buildings. Identifying and fixing these "poor performers" can save energy, water and resources, as well as improve comfort. And the savings can be significant- typically between 5 and 20% of operating costs depending on the facility.
