 Installed both high-efficiency equipment and renewable energy system
 Selected the most suitable equipment• Selecting the highest-end equipment by catalog specifications is not always the best choice.
• Since this was a project to replace existing equipment, we were able to select and install the most suitable
type and capacity of equipment, considering the past operation results.

3-1. Achievements
 Subsidy through JCM Model Projects allows for large-scale renewal•

STS has been installing energy-saving equipment that is highly profitable with a quick return on investment
expected.
E.g. LED lights, Inverters for ventilation fans•This project is large-scale equipment renewal and requires significant investment costs, but subsidy promoted
the realization of project implementation.

 Contribution to sustainable urban development in Indonesia•

Introducing advanced equipment with low environmental impact and maintaining them for 15 or 17 years willcontribute to reducing the frequency of construction work with high environmental impact.

•Senayan Square is the landmark of Jakarta, and it is expected to have a spread effect to other cities andbuildings in Indonesia by becoming a “Long-Life Model Project" for urban development that reduces
environmental impact in the building lifecycle.

3-2. What is Important to Succeed as JCM Model Projects
 Close and constant communications between Representative Participant and Local Partner•Since JCM Model Projects have a fixed project period, the project needs to be implemented smoothly.
 Discuss and develop a detailed plan in the consortium at the launch phase of the project.
 Share information about problems and manage risks together during project implementation phase.

•JCM Model Projects require long-term monitoring.
 Chillers and air conditioners need to be monitored for 15 years and Solar Power System need to bemonitored for 17 years (based on Japanese legal durable years).
 Build sustainable monitoring systems and continuous cooperation between Representative Participantand Local PartnerCopyright©2024, Yuko-Keiso Co., Ltd. All right reserved
