Establishment of Passive Energy Conservation Measure and Economic Evaluation of Fenestration System in Nonresidential Building of Korea

الملخص EN

ECO2 (building energy efficiency rating program) and passive energy conservation measures (ECMs) were established as a basic study for targeted methodologies and decision support systems development in Korea to meet national regulations.

The primary energy consumption and economic evaluation of nonresidential buildings was performed.

Passive ECMs were classified as planning and performance elements.

The planning elements are the window-to-wall ratio (WWR) and horizontal shading angle.

The performance elements are the thermal transmittance (U-value) of the walls, roof, and floor and the U-value and solar heat gain coefficient (SHGC) of windows.

This study focused on the window-to-wall ratio and the U-value and solar heat gain coefficient of windows.

An economic efficiency database for the constructed alternatives was built; the target building was set and the Passive ECM List for the target building was derived.

The energy consumption evaluation and economic evaluation were performed for each of the constructed alternatives, and a methodology for guiding energy efficiency decisions was proposed based on the performance evaluation results, and the optimal Passive ECM List for the target building was derived.
