Outline of Technology Study Committee’s Activity Report

1. Activities of the Technical Research WG2. Report on lectures held by the Technology Study Committee3. Overview of this fiscal year’s research (reconstruction of the energy

conservation technology road map)

The Technology Study Committee has consistently examined energy conservation technologies

from the viewpoints of energy conservation “of IT” and “by IT.”

The committee’s roles are to select themes that supplement WG activities or the latest trend

regarding Green IT from a policy-related perspective and to hold lectures by inviting experts in

respective fields.

The Technical Research WG, a sub-organization of the committee, researches the latest trends

of energy conservation technologies centering on various EMSs, through lectures on workplace-

level case studies, discussions with experts, literature search, etc. The WG identified indexes for

visualization and the key points of control, and indicated the future direction.

The following activities are reported:


1. Activities of the Technical Research WG


1.1 Background of the Research Importance of energy conservation and necessity of Green IT

Energy consumption and electrification rate are expected to increase.

Use of IT equipment is a major factor in the increasing power consumption.

For example, information transmitted via the Internet will increase 190 times and the

power consumption for IT equipment will increase five times, by 2025.

1.1 Background of the Research Issues highlighted by the Great East Japan Earthquake Disaster

The Great East Japan Earthquake Disaster caused extensive power failures mainly in the

areas served by Tokyo Electric Power Company and Tohoku Electric Power Company.

In the summer of 2011, demand had to be reduced by 10.3% and 7.4% in the areas served by

these two companies, respectively.

The “Energy White Paper 2011” pointed out: Tight power supply and rising costs are new

factors that may hinder future economic growth.

1.3 Overview of Last Fiscal Year’s WG Activities Research theme, research method, and key points

Theme Visualization and control

Targets Specific efforts regarding FEMS, BEMS, HEMS, Smart Community, and energy conservation-related devices

MethodHeld a WG lecture by inviting experts for respective targets, exchanged opinions with them, and held discussions among WG members

Overview of the research theme, targets and method

Key points

The trend of energy conservation may shift toward the control of various devices using information obtained through visualization.

Judging from the national electricity/energy conservation efforts in

response to the power shortages following the Great East Japan Earthquake Disaster, the control of various devices using information obtained through visualization may attract attention as a way to promote sustainable electricity/energy conservation while optimizing the demand-supply balance and maintaining quality of life.

1.5 Extracted Points on Future xEMS Modeling toward comprehensive EMS (1/3)

It will be necessary to shift from simple visualization to the control of various devices. Optimization of the whole of society is required rather than a single company or

household. The first step is to clarify the approach toward the system for energy/electricity

conservation.

The system that a company or household wants to (should) build/manage

(called “demander system”) is a system to manage these indexes.

From this perspective, xEMS is positioned as a sub-system of the demander

system.

Points Conclusion

Realizing mutual connectivity of interface among systems

Systems that help share visualized data and control equipment comprehensively is scarce.Mutual connectivity of interface among systems should be achieved.Discussions should be held based on demonstration experiments.

Using EMS as a system to control multiple devices

EMS should be used as a system to control multiple devices on a short time scale.Effective incentives should be studied.

Modeling toward comprehensive EMS, investigation on prospect of energy/electricity conservation

The first step is to estimate the level of energy/electricity conservation effects across systems and society.

What systems can satisfy needs should be discussed.

The household division targets energy consumption excluding transportation such as cars. The business division targets energy consumption in offices/buildings in companies’ administration division and in the tertiary industry such as hotels, department stores, and service businesses.

Source: “Energy White Paper 2011”

Units for grasping energy conservation effects are household, office, and factory. Upper-level units include city.

The trend of energy consumption in recent years indicates that energy consumption in factories is falling while that in households and offices is rising.

Thus, when investigating future energy conservation effects, the targets are households, offices, and cities.
