I saw in the ARC List that recommendations are coded by strategy and resource type. How granular is that coding? For example, would “heat exchanger cleaning” and “waste heat recovery with a recuperator” be in different codes?
Yes. The ARC system is structured to differentiate between general maintenance-based measures and capital investment measures. Heat exchanger cleaning is coded under “improve maintenance of heat transfer equipment” while recuperators or regenerators fall under “install waste heat recovery equipment.” This granularity allows the database to separate low-cost operational improvements from technology-based capital measures
