| Summary: | As in-suite heat recovery ventilator (HRV) use increases, cases of cross-contamination and odour transmission in MURBs are beginning to appear. To mitigate these issues and maximize HRV benefits, a better design and construction methodology specific to MURBs is required.
Previously conducted condition surveys suggest the possibility of the fresh air supply becoming contaminated by the exhaust air stream from adjacent units. It is suggested that the intake and exhaust configuration has a significant influence on the potential for cross contamination.
The results show cross contamination is an issue in high-rise condominiums. With a low exhaust vent angle and the right wind direction and speed, contaminants can travel from an exhaust source to a fresh air supply in a significant quantity. The potential impact here is to protect the health and safety of all home owners living in high-rise condominiums that utilize in-suite ventilation systems. |
