Mould Growth on wall Air quality is now a prominent issue in large measure because energy-efficient buildings have created airtight environments with less air exchange. In addition, synthetic construction materials and finishes emit gases and vapors into the indoor environment. The result is a greater impact on comfort and health, and occupant attitudes can result in dissatisfaction and loss of productivity in a working environment. PLEL provides consulting and testing services to investigate and control indoor air quality (IAQ) problems. Services provided by our team of Hygienists, Scientists, Engineers and Technologists include:

Review and evaluation of occupant concerns and activities.
Evaluation of the overall ventilation effectiveness by carbon dioxide mapping. Assessment of the design, operation, and maintenance of the heating, ventilation, and air conditioning (HVAC) systems.
Measurement of comfort parameters, including temperature, relative humidity, air pressure, air velocity, and carbon monoxide.
Examination of the building for contaminant sources in both the indoor and outdoor environment, with testing for specific contaminants where potential sources are identified (i.e. VOC's, ozone, formaldehyde, total dust, odour, etc.).
Preparation of a detailed report discussing the source of the problem with recommendations regarding control or reduction of the IAQ problems.
Microbiological testing to determine levels of specific types of fungus. Air samples, bulk samples, and surface samples are collected for analysis to establish degree and source of contamination.
Annual or bi-annual IAQ surveys to examine and record the effectiveness of the control measures.

FUNGUS & MOULD
Fungus and Mould The presence of microbial contamination (fungi or bacteria) in a building can present a health hazard to occupants of the building, or to construction workers during renovation or demolition. Problems arising from mould growth in absorbent building materials such as drywall, carpets and ceiling tiles have the potential to seriously impact the indoor environment. PLEL team members provide investigative, consulting, project management and remediation services, including specification development and project tendering.
