Australian newly built homes are 65% more airtight than nine years ago, according to CSIRO research, revealing potential issues such as condensation and mould.
CSIRO research reveals Australian newly built homes are 65% more airtight compared to those constructed nine years ago. Testing 233 new dwellings across various cities, CSIRO found potential issues in extremely airtight homes, such as condensation, mould, and higher levels of carbon dioxide and monoxide. Recommendations to improve airflow in new residential buildings include introducing airtightness standards in the National Construction Code, mandating controlled ventilation in apartment buildings, and making air barriers like building wraps compulsory. Displaying a home's airtightness value on National House Energy Rating Scheme certificates is also suggested.
