The research on retrofit tools addresses the question:

• How do I know the retrofits proposed for my building are the most important ones from a life cycle cost perspective?
• Building owners and managers need to be confident that energy service companies (ESCOs) and other retrofit agents are working with standard techniques of assessment that adequately reflect California building types, equipment, weather, utility costs, and other issues.

Tasks:

The goal is to deliver an operational, updated version of the retrofit tool (now named RESEM-CA).

The objective of this task is to enhance the RESEM-CA software tool with the following capabilities:

• Energy Conservation Measure (ECM) savings analysis
• ECM life-cycle analysis
• Ranking and determination of optimal packages
• Utility rate schedules
• Implement a Building template structure

The objective of this task is to enhance the RESEM-CA software tool with the following capabilities and prepare a public distribution version:

• Simulation Engine for new equipment
• ECM savings analysis: Energy Service Performance Contract economics analysis, including alternate (3rd party) financing, Include greening and renewables analyses
• Interoperability: Add interoperability capabilities for use with Industrial Foundation Classes
