Japan District Heating and Cooling Association

Overview of association activities

Toshio Ojima

Our association, the Japan District Heating and Cooling
Association, was established in 1972 as a voluntary organization
with the aim of popularizing district heating and cooling in Japan.
And it was certified as an incorporated association in 1993.
We have been expanding the business fields, answering thesocial need to realize a decarbonized and energy efficient city
design.
However, the Great East Japan Earthquake and the Fukushima
nuclear accident, which hit Japan in 2011, obliged us to change
the urban design policy as a “package of energy plan anddisaster prevention plan”.
It has passed around a half-century since our association wasfounded, and the role of our association has become more andmore important, purssueing zero-energy society, as anorganization, Bridging industry, academia, and government.
Japan has declared that it will reduce greenhouse gas emission
by 2050, and in order to contribute realizing the governmental
target, implementing BCD as a countermeasure against natural
disasters and realizing SDGs goals, our association is expected toplay a leading role and implement practical activities andprojects.
We recorded the 50th anniversary in 2022, and I would like to
ask you all for further guidance and encouragement in order torealize “safe, decarbonized and sustainable urban environment”.

Outline of our activities
Promoting the introduction of urban heat supply and treatment systems,
including district heating and cooling system, and promoting awarenessraising activities related to urban disaster prevention．

１ Realization of a city of smart use of heat

Examination of technologies and systems necessary for promoting thearea-wide use of heat, which accounts for a half of the final energy
demand, and activities to raise awareness２ Realization of disaster-resistant cities

Pursuing and development of the feasibility of commercialization ofBCD, for improving the disaster prevention of cities

３ Realization of decarbonized energy infrastructure

Planning and support for introducing renewable energy and hydrogenas core energy sources

Main activities
１ Survey■ Independent research

Supporting to realize safe and secure decarbonized cities by local
governments and conducting various independent researches. The results
have been published through our website.

■Holding seminars to disseminate the research results

Holding seminars to disclose the survey results conducted by theassociation. The survey results have been widely disclosed also to nonmembers.

２ Public awareness raising■ Urban Environmental Energy Symposium

Holding symposiums and facility tours focusing on area-wide use of heat,
energy conservation, disaster prevention, and decarbonization, etc., notonly for members but also for the general public.

■ Knowledge sharing with overseas

Conducting knowledge sharing events with overseas, on urban heat supply
and treatment systems, including district heating and cooling.
Concentrating on collecting and disseminating information bycommunicating with foreign associations and companies

３ Technology utilization■Urban environmental energy technology workshop

Holding workshops and facility tours for the purpose of maintaining andimproving knowledge and understanding the latest technologies related
to urban environmental energy.

■ Technical manual

Publishing a "technical manual" covering the design, construction, andmanagement of general heat source plants, including district heating andcooling. (As required)

Main activities
４ Supporting to accelerate project
implementation
Holding knowledge sharing events, inviting the central government,
local governments, and related organizations, summarizing the results,
and making recommendations to the central and local governments.

5 Publishing main activities■ Publication and distribution of journal

The association's journal "Urban Environmental Energy" is publishedquarterly, and distributed to members (heat supply companies, generalcontractors, subcontractors, manufacturers, design companies, etc.), local
governments, and related government agencies.
Providing the latest information, such as referential examples of project torealize a decarbonized society, urban development by local governments,and introduction of urban redevelopment projects. (Open to the publicthrough website)■ Website operation

Providing timely and useful information on the activities of the association,and utilizing it, as a basis for disseminating information.

■ Distribution of e-mail newsletters

Distributing the association's events and projects. Such as the publications
