Exam EDGE-Expert Topic 1 Question 90 Discussion

The CBCI EDGE curriculum explains that EDGE uses a simplified, quasi-steady-state approach to estimate building energy performance. To keep the method practical and consistent across many countries, EDGE relies on climate datasets that represent typical conditions over longer time steps rather than detailed hour-by- hour weather files used in dynamic simulation tools. In EDGE, the local climate inputs applied in the baseline and improved case calculations are based on monthly climate averages, including outdoor minimum and maximum temperatures, humidity, wind conditions, and solar radiation.
Monthly averages provide an effective balance between accuracy and usability. They capture seasonal variation that strongly influences heating and cooling loads, while avoiding the complexity and data intensity of hourly modeling. Weekly averages are not used because they add complexity without providing the standardized global consistency that EDGE aims for. Annual averages would be too coarse, because they would hide seasonal peaks and understate the impact of envelope and HVAC efficiency measures.
Therefore, the correct statement is that EDGE calculations use monthly average climate information for the key weather parameters listed.
