ジャカルタの既存ビルを対象に、NZEB化の技術的・財務的実現性を検討。省エネで18%削減、マイクロ水力で26%代替、BIPVで3%代替し、全体で電力の47%を再生可能エネルギーで賄う可能性を示した。投資回収期間は各施策で3.5年から137年と幅がある。

English

This study assesses the technical and financial viability of converting an existing building in Jakarta into a Net Zero Energy Building (NZEB). Energy efficiency measures reduce electricity use by 18%, a micro-hydro system using condenser pumps can replace 26% of grid electricity, and BIPV contributes 3%, totaling 47% grid replacement. Payback periods range from 3.5 to 137 years.

📄 Abstract（原文）

Abstract This Research is focusing to design technical and financial viability of Net Zero Energy Building (NZEB) from a study case of existing building in Jakarta, first by reduce Building’s energy consumption and employing renewable energy sources. The results showed that energy savings from implementing green building concept could reduce electricity usage by 18%and Return on Investment (ROI) 3.86 years, the utilization of the working scheme of the condenser pump to be used as a micro hydro power plant will generate Electric Power of 733.83 kW and have the potential to replace electricity supply from Grid/PLN by 26% and ROI 3.5 years, the installation of Building Integrated Photovoltaic (BIPV) has Potential to generated electricity 802,344 MWh/Year or 3% to replace electricity supply from Grid/PLN and ROI 137 Years. In general, the NZEB potential is 47% to replace electricity supply from Grid/PLN.
