Retrofit Measures for Mechanical Ventilation

Here you will find the data for Mechanical Ventilation measures available in the National Residential Efficiency Measures Database. Each measure consists of a before-component, an after-component, and the estimated cost to implement the measure. The measures are listed alphabetically based upon the name of the before-component. Where multiple costs are indicated they must be combined to obtain total measure cost (e.g., fixed ($) and normalized ($/sf) costs).

Cost Drivers

There are many factors that influence the ultimate cost of Mechanical Ventilation measures. The application of the average measure costs displayed below to any particular home is discouraged. Examples of the kinds of issues that can influence the cost of Mechanical Ventilation measures include:
  • Prevailing local wages
  • Drive time
  • Local code requirements
  • Attic height
  • Roof slope
  • Access
  • Presence/condition/type of existing insulation
  • Existing construction and materials
  • Moisture issues present
  • Condition of existing flue
  • Condition of existing electrical system
  • Need for additional wiring/switching
  • Adequacy of existing ventilation
  • Presence of hazardous materials
  • Condition of existing duct system
  • Type of equipment
