Abstract

This study examined the primary energy requirements and additional costs associated with different combinations of technology and improvement factors to achieve a zero-energy building (ZEB) grade for public order modular apartment houses. The analysis considered three stages of performance for six improvement factors. The findings revealed that individual enhancements to passive and active elements did not meet ZEB criteria. However, installing photovoltaic (PV) systems covering at least 40% of the rooftop area satisfied the ZEB 5th grade. To propose an effective combination of improvement factors for ZEB certification, the cost performance index was analyzed, and factors were prioritized accordingly. The analysis indicated incremental costs per unit area of 62,392 won for ZEB 5th grade, 96,380 won for ZEB 4th grade, and 120,389 won for ZEB 3rd grade. This study holds significance as it provides insights into energy performance and incremental costs during the introduction of zero-energy buildings and modular apartment houses.
