Energy Saving Quantitative Analysis of Passive, Active, and Renewable Technologies in Different Climate Zones

The purpose of this study was to provide a guideline for the selection technologies suitable ASHRAE international climate zones when designing high-performance buildings. In study, were grouped as passive, active, and renewable energy systems. Energy saving comprising 15 cases categorized into EnergyPlus v9.5.0 used analyze contribution each technology in reducing primary consumption. consumption system analyzed different climates (Incheon, New Delhi, Minneapolis, Berlin), detailed contributions evaluated. Even same is applied, rate differs according climatic characteristics. Shading systems are passive that more effective hot regions. addition, variable air volume (VAV) system, combined VAV–energy recovery ventilation (ERV), VAV–underfloor distribution (UFAD) active can convert humid outdoor temperatures create comfortable indoor environments. cold cool regions, prevent heat loss, such high-R insulation walls windows, effective. Active utilize or include VAV-economizer, chilled beam with dedicated (DOAS), VAV-ERV. For systems, ground source pump (GSHP) Selecting surrounding environment, selecting design strategies appropriate given climate, very important buildings globally.
