Abstract
In the early 2000s, the Korean government mandated the construction of only zero-energy residential buildings by 2025 and for non-residential buildings from 2030. Two decades since the start of building energy policy enforcement, Korean experts believe that it is time to evaluate its impact. However, few studies have systematically and extensively examined the energy consumption characteristics of the non-residential building stock. In this study, a framework development is implemented for defining non-residential prototypical office buildings based on Korea’s first large-scale non-residential building survey result from the Korea Energy Economics Institute (KEEI). Then, a detailed building energy model of the defined prototypical building is constructed to verify the model’s energy estimation against observed energy consumption. As an application of the model, a case study for energy policy evaluation utilizing the constructed prototypical building model is presented. Every researcher and county may have their own circumstances when gathering definition data. However, by using the best available representative data, this suggested framework may result in informed decisions regarding energy policy development and evaluation. In addition, the mitigation of greenhouse gases from buildings may be expedited.

The building energy model constructed using the definition of Large-1 prototypical office buildings represents the overall energy consumption characteristics of the office building stock
This study describes the process of conducting a large-scale building survey, analyzing the survey results, and applying engineering knowledge to develop prototypical office building models in Korea
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. A widely-used guide for this purpose is the ASHRAE Standard 90.1 (App G), which provides detailed building energy model procedures and methods based on prototypical non-residential building. The development of reliable PBs in Korea is still relatively immature owing to the scarcity of energy-related building data and published research papers. The survey enabled the development of PBs with statistically processed data on building energy consumption. A framework for defining non-residential PBs was developed based on the survey results from the KEEI.
