Heating, cooling and ventilation / Project guide

Building ventilation assessment

Prepare an assessment of ventilation concerns using the building’s actual spaces, operating patterns and equipment history. Describe complaints precisely and ask a qualified provider to define an investigation that can support a practical next decision.

The decision this helps you make

What to aim for.

A documented assessment connecting observations to the systems reviewed, remaining questions and recommended follow-up.

Start with the information below, then choose your property type for the access, operating and decision-making details that shape the project.

Define the scope.

  • Identify the rooms or common spaces associated with the reported ventilation concerns.
  • Describe when symptoms occur and whether they relate to occupancy or equipment operation.
  • Ask the assessor to define the systems, observations and measurements included in the visit.

Put these records together.

  • Gather available mechanical drawings, equipment schedules and existing maintenance or balancing reports.
  • Provide a dated complaint log and records of recent changes to the spaces.
  • Identify operating schedules and the people who control equipment access or settings.

Choose your property type.

Ask for a comparable proposal.

  • State the investigation method and the areas included in the assessment.
  • Separate initial observations from additional testing, design or corrective work that may follow.
  • Ask the report to identify assumptions, assessment limits and recommended next-stage responsibilities.

Understand what affects the cost.

Ask providers to price the same scope and explain the assumptions behind these items.

  • The number of affected spaces and the systems that need investigation.
  • The quality of existing records and access to equipment serving occupied areas.
  • Additional visits or measurements needed to observe different operating conditions.

Project: Building ventilation assessment

Agree on the handover.

  • Keep the findings with dates, assessed areas and the operating conditions observed.
  • Record changes made during the assessment and who authorized those changes.
  • Create a follow-up brief separating maintenance actions from further professional investigation or design.

Questions before you begin.

Should we ask for new ventilation equipment at the start?

Describe the observed problem and the decision you need to make. Ask the provider to investigate the current operation and explain the evidence for maintenance, adjustments, further assessment or equipment changes.

How should occupant complaints be recorded?

Collect the location, time, description and relevant operating circumstances without making a diagnosis. A consistent log helps the assessor identify which conditions to review and what additional information would be useful.

Continue planning.
