EPRI Evaluation

The Best in Internet Customer Services —
HomeVIEW Internet Customer Services:

Viewtech pioneered internet-based customer services with the first internet energy bill analysis offered through Central and South West Utilities. With 25 years experience performing over 1.5 million energy audits, Viewtech converted its proprietary energy audit software to operate on internet servers. Despite the challenge of significantly reducing and simplifying the software’s data input--which was originally designed for experienced energy auditors—while maintaining accuracy, Viewtech’s efforts resulted in a product evaluated by the Electric Power Research Institute (EPRI) receiving the highest scores in User Interface, Accuracy (by two rankings), and Reports and Recommendations, against competing products.

The following tables are from the EPRI Evaluation.
