The National Retrofit Measures Database offers the following benefits:

• Provides information in a standardized format
  
• Improves the technical consistency and accuracy of the results of software programs
  
• Enables experts and stakeholders to view the retrofit information and provide comments to improve data quality
  
• Supports building science R&D
  
• Enhances transparency.

Measure and Cost Data

Data includes performance parameters for retrofit measure categories and a range of estimate costs that one might expect to find for the different measures. Measure categories include:

• Appliances
  
• Domestic hot water
  
• Building enclosures (e.g, walls, windows, roofs)
  
• HVAC
  
• Lighting.

Full cost estimates are available for many different retrofit measures and they represent the total cost to implement the measure. For each measure, the database provides a range of costs, as the cost data for a measure can vary widely across regions, houses, and contractors. Climate, construction, home features, local economy, and geographic location all affect the actual cost to perform any of these measures.
