Indoor Air Quality (IAQ) is one of the most complex challenges facing the building industry today. Of all potential IAQ concerns, mould (mold) and moisture combined are by far the most serious of the IAQ challenges facing the building management and construction industry today. In fact Volume 2 of the Barrett Report (on leaky condos) determined that mould (mold) and moisture resulting from building envelope failures can impact both the structural durability of the building and the health of both the building occupants and the construction workers.
Our firm, Sterling IAQ Consultants Ltd. has become directly involved in this issue investigating concerns resulting from exposure to mould (mold) in moisture troubled buildings.
Causes of Mould Growth in Buildings
Mould (mold) and moisture damage to the building is caused by a number of factors:
- Moisture and condensation in the HVAC System.
- Leaks in the building envelope from the foundation up to the roof.
- Leaks caused by faulty plumbing or poor workmanship.
- Moisture existing in the building materials before construction and sealed into the envelope.
- Moisture caused by occupant activities such as showering or bathing.
- Moisture caused by combustion sources particularly open flame cooking and heating appliances such as stoves and water heaters.
- Poor site drainage.
