Poor ventilation permits many airborne pollutants and excess moisture to build up within your residence. This could cause health complications like asthma for the entire household. Moisture could also damage the structure of your house and also make it uncomfortable for habituation.

For example, the Building Code of Australia (BCA) states that you should have windows which are equal in their total size to at least 10 per cent of the house floor space. The BCA takes into consideration the recommendations contained in the ASHRAE Standards 62.2 – Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings, published in the ASHRAE Handbook. ASHRAE is a global society that promotes the well-being of humans through sustainable technology.
When Is The Right Time To Consider Ventilation?
International Code Council's Section 403 – Mechanical Ventilation recommends that when mechanical home ventilation is being employed, specific ventilation rates get calculated based on the occupancy and building structure type. This is covered under the International Mechanical Code.
