- Universal Translator v3 - The UT3 is software designed for the management and analysis of data from loggers and trend data from building management systems. The software features import routines, time and interval correction, calibration error correction, data filters, charting tools, and export capabilities. It also features analysis modules to analyze economizers, lighting loads, plug loads, psychometrics, setpoints, statistics, control loop diagnostics, fans, AHUs, terminal units, fan coils, and an M&V analysis module (regression modeling).

- SPB, SIR, IRR, NPV
- LCCA - NIST Life Cycle Costing Handbook 135
- International Energy Efficiency Financing Protocol, 2009 (EVO) - the global “blue print” for educating and training LFI personnel around the world on the special intricacies, benefits and risks associated with financing ESPs. It is intended to be a growing set of best practices, resource materials, case studies, standardized tools and guidelines to support LFIs and other energy efficiency stakeholders in their economic and financial evaluation of ESPs.
