CRU (Certified in the Use of RETScreen) exam help guide

CRU and RETScreen Overview

CRU is commonly expanded as Certified in the Use of RETScreen, a credential associated with RETScreen clean energy analysis skills. RETScreen itself is Natural Resources Canada's clean energy management software platform for low-carbon planning, implementation, monitoring, and reporting. It is used by energy, facility, and sustainability professionals to assess projects, compare options, and track performance.

Current AEE-facing CRU materials are sparse compared with active AEE certification pages. That means this page should not imply a modern AEE exam blueprint unless the candidate has confirmed one through the current provider. Treat CRU as a RETScreen credential or legacy pathway that requires provider verification before scheduling.

Provider Verification First

Before studying for an exam date, verify whether CRU is currently offered by the provider you plan to use, whether it has been replaced by Certified RETScreen Expert or another RETScreen training path, and whether any AEE affiliation still applies. Ask for the current syllabus, assessment format, allowed software version, exam delivery mode, fee, passing standard, and renewal or continuing education requirements.

Also confirm which RETScreen product version the training uses. Older CRU references may point to earlier RETScreen workflows, while current professional work often centers on RETScreen Expert. Version mismatch can waste study time because menus, project structure, modules, and reporting outputs may differ.

Core RETScreen Study Areas

A practical CRU or RETScreen credential plan should start with project setup. Candidates should understand how to define the project, select location and climate inputs, choose the technology or measure type, enter baseline and proposed-case assumptions, manage utility and fuel data, and document assumptions clearly enough for someone else to review.

The second layer is analysis. Build fluency in energy production or savings estimates, emissions reduction calculations, financial analysis, sensitivity checks, risk inputs, monitoring data, and report interpretation. The exam or assessment may not only ask what a field means; it may expect you to interpret whether an output is plausible.

Clean Energy Project Context

RETScreen is used across energy efficiency, renewable energy, cogeneration, heating and cooling, and low-carbon planning contexts. A candidate should be able to connect the software workflow to the real project question: Is the measure technically feasible, financially viable, emissions-reducing, and worth further development?

That means studying the underlying project logic, not just the interface. Review load assumptions, resource data, equipment performance, capital and operating costs, incentives, fuel escalation, emissions factors, and how changes in assumptions affect project economics.

Monitoring and Reporting

RETScreen is also positioned for monitoring and reporting, so include post-implementation thinking in your study plan. Know how measured data can be compared against expected performance, how dashboards or reports communicate outcomes, and how poor data quality can undermine a clean energy claim.

For organizations, this is often the most valuable part of the workflow. A good user can explain not only projected savings but also how to track whether those savings are happening. If a credential assessment includes reporting interpretation, practice reading outputs and explaining them in plain language.

Readiness Checklist

Confirm the provider, credential name, software version, assessment type, delivery mode, and allowed resources. Install or access the correct RETScreen version, complete several project cases end-to-end, and practice explaining assumptions, calculations, financial results, emissions impacts, and monitoring outputs.

If no current CRU exam is available, redirect the plan toward active RETScreen training or Certified RETScreen Expert options. The useful outcome is still the same: demonstrated ability to use RETScreen for practical clean energy analysis, not just holding a dated acronym.
