On July 23, the ZEB Solutions Working Group successfully co-hosted a ZEB (Net Zero Energy Building) workshop/seminar in Jakarta, the capital city of Indonesia, in collaboration with the Ministry of Energy and Mineral Resources (MEMR) of Indonesia.

The Workshop/Seminar was held at a hotel in Jakarta, with 46 participants attending in person and approximately 80 participants attending online, totaling over 120 attendees, creating a vibrant and engaging event.

This seminar featured presentations from the following key institutions promoting Indonesia's energy conservation policies, where their advanced initiatives were introduced.

  - Ministry of Energy and Mineral Resources (MEMR)

  - Green Building Office under the Ministry of Public Works and Housing (MPWH)

  - Jakarta City Urban Planning Department

From the Japanese side, we provided an overview of the latest ZEB policy trends, an explanation of the advanced energy consumption simulation program “WEBPRO,” and introductions of outstanding products and technologies by member companies of the working group, which garnered significant interest from participants.

Building on this success, as the working group activity of JASE-W, we will continue to deepen collaboration with the Indonesian government and Jakarta City to pursue the development of pilot project proposals in Jakarta.

In March 2025, JASE-W dispatched a mission to Papua New Guinea in response to a request for cooperation in geothermal development from Kumul Consolidated Holdings, and held discussions with them, National Energy Authority and others.  In addition, JASE-W made site visits to potential geothermal development areas: Wau Bulolo, Morobe Province in the eastern part of the main island, and New Britain Island.  JASE-W will continue to study the feasibility of geothermal development in Papua New Guinea in cooperation with Kumul Consolidated Holdings and other government agencies.
