Program Results
Response to Power Saving (Max. Power Demand) after Great East Japan Earthquake[Reduction Ratio of Max. Service Power Comparedwith 2010 Summer]
Max. service power was “reduced by 15% or more” at 80% of the facilities.
(* There are some facilities beyond the scope of Article 27 of the Electricity
Business Act.)
30% or more

(Survey results by Tokyo Metropolitan Government (December 2011))
Owing to “preparation of the promotion structure” and “participation by the tenant facility
owners”;“Power saving went smoothly because there was already a cooperative addressing
structure before the Great East Japan Earthquake, holding a tenant meeting twice
annually.” (Voice of a tenant building owner)
Because a “list of devices, etc. had been prepared” in order to respond to this program;“An accurately calculated effect of reduction greatly helped planning of power saving
measures, resulting in smooth power saving.” (Voice of a plant owner)

Q: Was the promotion structure of thisprogram utilized for power saving after
the Great East Japan Earthquake in2011?
Utilized greatly: 13%
Utilized: 68%
Not utilized: 19%

Considering the owner as mainly responsible for the obligation, thetenant is subjected to the following duties.
◆ All the tenants are obligated to cooperate with the facility owner’s
reduction measures.
◆ The facility owners such as specified tenants* are obligated to prepare
and submit their original strategic plans and promote the measures basedon the plans.

* Requirements for the facility owners such as specified tenants
 Facility owners using a floor area of 5,000 m2 or more as of the end of theprevious fiscal year Facility owners whose electric consumption for the previous one fiscal year
(from April to the end of March) was 6,000,000 kWh or more.

25

Certification Criteria for Top-level Facilities●The currently feasible highest-level energy conservation measures are set based on the
results of surveying the latest energy conservation buildings and interviewing the
manufacturers.
●The criteria is to be utilized as a reference index for design when constructing new building
or implementing large-scale improvement.
●Energy conservation tuning in the operation phase, such as the promotion structure and theoperation management, is also a requirement.
Design Phase○ Load control  “Improved building skin performance (high-performance glass Low-e, etc.)”“Internal load control (high-efficiency lighting LED, etc.)”“Outdoor air load control (outdoor air rate control, etc.)”○ Utilization of natural energy  “Natural lighting, natural ventilation, outdoor air cooling, etc.”○ High-efficiency equipment system  “Introduction of high-efficiency system (radiation heating-cooling system,etc.)”“Introduction of high-efficiency equipment (high-efficiency heat source, highefficiency motor, etc.)”“Adequate capacity division of equipment”“Introduction of energy conservation control (variable flow rate control, etc.)”○ Utilization of renewable energy  “Utilization of solar power generation and solar heat, and so on.”Operation Phase○ High-efficiency operation  “Implementation of commissioning and tuning, and so on”○ Building of the energy conservation measures promotion structure
 “Establishment and opening of CO2 reduction promotion conference, and so on”

Looking to the Most Environmentally-advanced
City in the World
September 2013: C40 & Siemens City Climate Leadership Awards (at London)▪ Commends a municipality carrying out a remarkable climate change strategy. It was
highly assessed that CO2 emissions had been reduced by 23% in the second year after
starting the Cap-and-Trade Program.

June 2014: UNFCCC Expert Meeting (at Bonn)▪ At the UN Climate Change Conference, Tokyo’s experiences were presented
in a place for sharing the approach cases for raising the 2020 reduction goals.

September 2014: UN Climate Summit (at New York)▪ A video message was put on the screen in approval of an appeal from the World Bank at
a summit conference in order to promote climate change negotiations among nations.
Responses to international
conferences, etc.

December 2011: COP17 Government Leadership Award (at Durban)▪ Commends a municipality taking the measures for remarkable city planning,
low-carbon buildings, etc. The world’s first establishment of the urban type Capand-Trade Program was highly assessed.
