Other issues appear when governance timing and evidence format are not aligned with the provider’s documentation pattern. SGS and TÜV Rheinland deliver audit-ready reporting workflows built around inspection-style evidence handling, which differs from providers that prioritize program-integrated evaluation delivery like CLEAResult.
Assuming automation and API integration are the primary delivery mechanism
Opinion Dynamics is services-led and limits automation and API surface, so buyers that need automated ingestion for ongoing runs should set expectations early with ICF or other providers that match a workflow-first model.
Treating weather normalization as a generic adjustment rather than a documented comparison method
Opinion Dynamics uses degree-day methods for weather normalization, so buyers should specify the comparison basis for baseline decisions instead of only requesting general weather adjustments.
Skipping disciplined data preparation for interval meter or utility inputs
Opinion Dynamics has strong savings calculation documentation, but it requires disciplined data prep and clear treatment group definitions to preserve traceability from inputs to results.
Choosing an evaluation provider that ignores how the program actually recruits and tracks participants
CLEAResult aligns baseline and savings assumptions with how participants are recruited and tracked, so buyers using a different program workflow pattern can force rework.
Expecting a self-serve analytics export pattern from inspection-evidence or assurance-first delivery
