CMHC Kitchener townhouse study of sub-slab venting technology.Phase II / prepared for the Research Division, Canada Mortgage and Housing Corporation ; prepared by CH2M Hill Engineering Ltd.: NH17-173/1990E-PDF
"Sub-slab venting, a common technology used for the remediation of radon entry into homes, was applied to a group of methane plagued townhouses in Kitchener, Ontario. This soil ventilation essentially modifies the local pressure distribution around the basement structures such that air flow is from basements out toward the soil zone. Work performed in the previous year established the technical feasibility of this technology. This study was a second phase of work aimed at assessing the suitability of this technology across the entire townhouse site. The results of the monitoring program revealed that sub-slab ventilation was suitable as a mitigative measure at the townhouses. Significant improvements to the indoor air quality were observed. Vent gases were also tested to identify the presence of any hazardous organic compounds; no significant compounds were identified. An energy analysis was also performed to evaluate the impact of sub-slab venting on energy consumption within the homes"--Abstract, p. ii.
