6.6204.1 Commissioning Ventilation Systems

Topic: 
Whole Building Ventilation
Subtopic: 
System Evaluation
Desired Outcome: 

Verify proper operation of existing system,installed system air flow meets required standard and provides continuous ventilation for background pollutant sources

TitleSpecification(s)Objective(s)
6.6204.1a
Identification

Identify whole building ventilation strategy that was installed in the home, based on options described in current version of ASHRAE ASHRAE American Society of Heating, Refrigerating and Air-Conditioning Engineers, www.ashrae.org 62.2, e.g., exhaust only, supply only, balanced, combining local and whole home ventilation delivery, incorporating infiltration Infiltration The uncontrolled passage of outside air into a building through unintended leaks in the building envelope credit, etc.

Ensure suitable whole building ventilation strategy is installed

Identify testing requirements to determine installed system air flow

6.6204.1b
Equipment inspection

Visually inspect and document status of:

  • Electrical connections
  • Name plate (rated sone and flow)
  • Motor cleanliness
     

Evaluate equipment

6.6204.1c
Pathway inspection

Visually inspect and document status of ducting or other airflow pathways to ensure proper:

  • Conections (proper materials, sealed and connected)
  • Insulation
  • Support
  • Sizing, and
  • Termination locations and fittings

Verify proper damper operation

Preserve integrity of building envelope Envelope The separation between the interior and exterior environments of a building that includes a combination of air and thermal barrier

Effectively move air along selected pathways

6.6204.1d
Measurement and Adjustment

Using a calibrated device, measure air flow of all necessary components, including building air leakage when relevant

Adjust ventilation equipment air flows as necessary to meet the ventilation rates required by the current version of ASHRAE ASHRAE American Society of Heating, Refrigerating and Air-Conditioning Engineers, www.ashrae.org 62.2.

Provide sufficient air flows per current ventilation standards

Verify suitable performance of installed ventilation strategy

6.6204.1e
Work order

Develop work order as necessary to correct deficiencies identified during inspections and measurement

Correct deficiencies

Ensure proper operation

6.6204.1f
Occupant education

Instruct occupant on purpose, use and maintenance of ventilation, and typical signs that ventilation is needed, e.g., condensation on windows

Occupant understands benefits of good indoor air quality and can operate ventilation equipment as needed
