In the CBCI EDGE curriculum, the EDGE Baseline is not fixed permanently because construction practices, typical system efficiencies, and national or city regulations evolve over time. To ensure that EDGE continues to represent a realistic and fair comparison against “standard practice” in each location, the EDGE Baseline is periodically reviewed and updated. The curriculum explains that baseline reviews are undertaken every 3 to 5 years when needed, and this review can include updates to the geographic coverage of EDGE, such as adding new countries or refining baselines where market conditions or codes have changed.
This review cycle helps maintain the credibility of the 20 percent savings thresholds by making sure the baseline remains aligned with what is commonly built in a given market. If baselines were updated too frequently, it would create instability for project planning; if updated too rarely, the baseline could become outdated and no longer reflect typical practice. The 3 to 5 year interval balances stability with relevance, ensuring that EDGE benchmarking stays accurate across different regions and over time.
