미세먼지 저감 신축학껓 설계안의 에너지효율 분석 (Energy Efficiency Analysis of New School Design for Fine Dust Reduction)

Purpose: The purpose of this study is to suggest an optimal energy efficiency plan for the design of a new school with fine dust reduction. Method: To this end, we simulated energy comsumption of the existing school design (Case 1) and the new school design plans reflecting three energy saving alternatives (Case 2, Case 3, and Case 4). Result: As a result of the simulation analysis using E+, the energy consumption for Case 1 was 59.82kWh/㎡ ·a, Case 2 was 66.43kWh/㎡·a, Case 3 was 64.56kWh/㎡·a, and Case 4 was 43.18kWh/㎡·a. The new school design plan considering passive elements (Case 4) was the most advantageous for energy saving. It was possible to save 27.81% of energy compared to the existing school design. In addition, the passive element that has the greatest impact on energy saving is airtightness performance, and it was thought desirable to design ACH50 below 10. The study results will be useful for energy-saving design of new school building with fine dust reduction.
