Ventilation Survey

Ventilation survey plays very vital role in understanding indoor quality in industries, homes, schools or offices and based on Ventilation survey reports steps can be taken to repair ventilation system. Research shows that right indoor air quality improves productivity of employees. It reduces accidents, absenteeism and chemical exposure of employees resulting in improving profit for business.

In ventilation survey information is collected by building inspection, measurement of air exchange, pressure, carbon dioxide & particulate matter (PM10 & PM2.5) concentrations through main flow-paths of ventilation system.

Ventilation survey procedure

Natural ventilation through open window is effective strategy to maintain clean air and temperature in some portions of cooling season. To calculate energy saved in buildings through natural ventilation one has to calculate air flow.

Measurements of airflow needs to be taken from all underground facilities at times and places to:

• Ensure all places in industries, offices, schools or homes can receive their required airflows in an efficient and effective manner
• Verify ventilation plans are upto date and provide information for short and long term ventilation planning
• To identify the extent of air leakage, in case of any repair the same
• To identify locations where boosters fans are reuired
• To To verify direction of airflow, quantities and separate identities of inlet and outlet are maintained

Also routine measurements of pressure measurement across doors maintained within limits and in correct direction.
