Project Data Center

Freight container which is transportable by container truck/trailer and is(Project DC)

outfitted with components including server racks, power supplies,
communication wirings, cooling facilities, fire-extinguishing facilities,and the following features:- Outside-air cooling method- Remote management system- Automatic switching

Outside-air cooling

A method of cooling which utilizes outside air efficiently. This involves

methoddirect intake of the outside air to inside of the DC in order to cool theroom temperature to maintain the DC-recommended temperaturecondition.

Remote management

A system which remotely monitors and controls the temperature andsystemelectricity consumption of the project DC to control a variety ofequipment including cooling and IT equipment and to achieve stable
operation automatically without using human on-site monitoring or
operation, in order to avoid energy loss caused by manual operation,such as door opening and closing to operate manually and adopt themethod to automatically reduce energy consumption losses formaintenance.

Automatic switching

A system to automatically switch on the refrigerated air conditioning
system when the cooling capacity of the outside air is not sufficient tomeet the recommended temperature condition.

DC-recommended

The recommended temperature condition for IT equipment operation

temperature

which is established by the manufacturers.

Power Usage

PUE is the metric to show the efficiency of DC power use. PUE isEffectiveness (PUE)

defined by the following formula;
PUE =Overall electricity consumption of DCElectricity consumption of IT equipment of DC2

JCM_LA_F_PM_ver01.0

PUE is calculated based on the methodology developed by the Green
Grid.1

C. Summary of the methodology
Items

emission

Summaryreduction Energy reduction which leads to reductions of GHG is achieved

measuresby introducing energy-efficient project DC in place of thereference DC.

Calculationofreference Reference emissions are calculated by multiplying theemissions

monitored electricity consumption of the project DC, ratio ofreference DC’s PUE to project DC’s PUE, and the CO2 emission
factor of electricity.

Calculationofproject GHG emissions associated with electricity consumption ofemissions

project DC are calculated by multiplying the monitored
electricity consumption of the project DC by the emission factorof electricity.

Monitoring parameters

Electricity consumption of entire project DC and IT equipment.

D. Eligibility criteria

This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1
Criterion 2
Criterion 3
Criterion 4Criterion 5

The project DC is newly introduced, highly efficient with designed PUE value
under 1.3.
The container is highly air-tight with IEC60529 value of IP-54 or higher basedon manufacturer’s inspection results.
The project DC installs IT equipment that has operating temperature
recommended by manufacturer with upper limit of 40 degrees C or higher.
Ozone Depletion Potential (ODP) of the refrigerant used for the project DC iszero.
A plan for not releasing refrigerant used for project DC is prepared.

The Green Grid is a neutral, diverse, consensus-driven consortium providing a unified voice for the industry on
resource efficiency (including resource efficiency of DC). In 2015, it had 112 member companies(http://www.thegreengrid.org).

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated by multiplying the monitored electricity consumption of theproject DC, ratio of reference DC’s PUE to project DC’s PUE, and the CO2 emission factor ofelectricity.
In this methodology, PUE values are adopted as the efficiency indicator of DC. Net emission
reductions are achieved in this methodology by conservatively setting the PUE value for thereference DC.
In this methodology, the default value of the PUE of the reference DC is conservatively set at2.0.
The PUE of project DC is calculated with monitored electricity consumption of project DC as awhole and IT equipment of project DC.
