Normative building modeling, addressed in ISO 13790 (Thermal performance of buildings-Calculations of energy use for space heating), has been adopted in major European countries in various applications, including building energy certificate and energy forecast for building stock in regional, national, or international scale. This wide adoption in Europe stems from the capability of normative modeling to deliver objective, yet indicative building energy performance results. This study presents a simplified approach for building energy model calibration by coupling normative energy calculation method and the Latin Hypercube Sampling (LHS) method. The light weight normative energy calculation method requires a limited number of building inputs which could be collected through a quick walk-through onsite audit. And its minimum computation requirements allow the calibration process to search the entire feasible space more thoroughly and in a timely manner. Coupling normative energy calculation and LHS provides users a simple and yet effective tool for building audit and energy model calibration in support of retrofit decision making. A case study on an existing mix-use university building is presented to demonstrate the performance of the proposed approach. Limitations and suggestions to future work are also discussed.
