ASHRAE Guideline 14-2014 declares a whole-building energy model calibrated to monthly data if the absolute NMBE is less than 5% and CV(RMSE) is less than 15%, a materially tighter tolerance than the hourly criteria.

ASHRAE 62.1-2022 §6.2.2.1 prescribes minimum outdoor air ventilation rates for office space at 5 cfm/person plus 0.06 cfm/sqft

ASHRAE Guideline 14-2014 declares a whole-building energy model calibrated to hourly data if the Normalized Mean Bias Error (NMBE) is within ±10% and the Coefficient of Variation of the Root Mean Square Error, CV(RMSE), is within ±30%.

GB 55015-2021 requires an average building energy-savings rate of 75% for residential buildings in severe cold climate zones, 65% for residential buildings in other climate zones, and 72% for public buildings, relative to the pre-reform-era (1980s) baseline used in the Chinese building energy-code system.
