This toolkit includes resources to assist utilities and efficiency programs in understanding and incentivizing high-efficiency RTU replacements. Reference guidance on various considerations including calculators, sizing guidance, procurement specifications, financial business cases, case studies, and M&V methods.

TOOLS

Decision Tree for RTU Replacements or Retrofits Guidance
This decision tree guides the reader through the challenging task of determining how to manage existing rooftop units with easy to follow evaluation questions and links to additional resources for more information.

RTU Inventory Spreadsheet Guidance
Use the RTU Inventory Spreadsheet to gather basic information (i.e., number, size, age, condition, etc.) about your RTUs. Use the detailed fields to gather additional information (i.e., controls, usage patterns, features, etc.) for additional analysis of the RTUs identified for retrofit, replacement, or further analysis.

RTU Comparison Calculator Tools
The Rooftop Unit Comparison Calculator (RTUCC) compares high-efficiency rooftop air conditioners to standard equipment in terms of life cycle cost.

Business Case for Proactive Rooftop Unit (RTU) Replacement Report
This document introduces the key elements to consider in making the business case for a proactive high-efficiency RTU replacement strategy for facility maintenance staff and building engineers responsible for energy management.

RTU Sizing Guidance Guidance
Common sizing mistakes (with respect to cooling tonnage and supply fan horsepower) can be controlled with these recommended processes to help project teams avoid those mistakes and ensure effective RTU replacement investments.
