The designer would specify the foundation bolt outdoor air and exhaust air volumes required by code, but would stop short of comparing the totals to check the ventilation balance. Frequently, this led to over pressurized buildings wu bolt doorways were transformed into wind tunnels. In some cases, buildings became negatively pressurized and infiltration made indoor climate control difficult.
Stand alone ERV systems inu boltntly remind the HVAC engineer to perform the building balance check because the outdoor air and exhaust air volumes are located on the same equipment schedule. Additionally, the outdoor air and exhaust air fans are interlocked within the ERV control center. This translates into the following benefits of a stand alone ERV compared to a bolt-on:
The ventilation design is more likely to meet the engineer’s intentions, typically a slightly positive building pressure. System balancing after installation is far easier on a stand alone system. Exhaust and outdoor air duct runs provide recommended locations for airflow measurement. Determining exhaust and outdoor air volumes in the bolt-on configuration is practically impossible. Exhaust fans and outdoor air fans are simultaneously energized so the building operates as it was designed.
Separate controls, interlocks, and field coordination to maintain a balanced building are eliminated. (Note: In some traditional systems without energy recovery, exhaust fans were energized by occupancy sensors (i.e., motion detectors or light switches) in an effort to save energy.
