Background of Kitakyushu – Surabaya City-to-City Cooperation
1. Objective of the Kitakyushu Model■ Kitakyushu, which faced and overcame pollution for thefirst time in Asia, became a leading environmental cityin Japan.
■ Kitakyushu is developing the Kitakyushu Model(support tool) that systematically arranges informationon the technologies and know-how of Kitakyushu fromits experience in overcoming pollution to its quest as anenvironmental city.
■ Kitakyushu is utilizing the Kitakyushu Model to promote
the export of customized infrastructure packages tocities overseas, and grow together with Asia.

Project Outline5Outline of GHG Mitigation Activity
More than 30% Energy Saving

The project aims to reduce electricity
consumption in the shopping mall throughintroducing advanced & efficient Japanese
Cooling
centrifugal Chiller system.
The project is to replace existing central cooling Tower
system with high efficient centrifugal chiller withcapacity of 966TR x 4 units and 569TR x 1 unit
in Pakuwon’s shopping mall, Tunjungan Plaza,
as well as to replace existing 8 cooling towers
with efficient Japanese models.

Estemated GHG Emission Reductions Sites of JCM Model Project
386tCO2/year
The GHG emission reductions arecalculated based on the estimated electricity
consumptions based on the conservatively
estimated COP of a reference coolingsystem and a project COP of the centrifugal
chiller as well as the grid emission factor.

10Viewpoint of technology replication
Technology replication is not difficult technically. However some ofchallenges are initial cost and refrigerant issue.

2Expansion to other private buildings
Propose to other potential buildings which is owned by the developer
based on this successful model project.

3Interrelation with Green Building Awareness AwardSurabaya City is developing GBAA as part of their political measures andthey will newly develop Green Building Regulation in future.
The interrelation between JCM and GBAA will be preferred.
(ex. JCM credit can be converted as GBAA credit points)
