Green IT
Definition
Green IT, also known as responsible digital technology, designates the solutions that enable companies to reduce the carbon impact of their information systems by minimizing CO2 emissions and energy consumption, e.g. geothermal, solar, wind, biomass, natural gas, oil, nuclear, etc.
EndDefinition
You can use different functionalities in Service Manager to:
- Measure the impact of equipment manufacturing.
- Simulate energy savings and costs when replacing certain equipment.
- Monitor suppliers and manufacturers using the Power Usage Effectiveness (PUE) indicator.
- Define the contractors in charge of equipment recycling.
You can now use dedicated Green IT reports to monitor initiatives in terms of sustainability and Green IT.
Notes
- Recycling information can be specified when discarding an item of equipment and for equipment with a specified discard date.
- You can modify this information in the Equipment Inventory as long as the discard date has not been reached. This information is based on projections.
- Once the item of equipment has been discarded, you can only modify its information using the specific wizard available in the Green IT menu.
- You define recycling contractors in the Supplier Directory.
Caution
- During the simulation, CO2 emissions will not be calculated if the relevant data is not specified in equipment locations.
Best Practice
- To display discarded equipment:
- Display the Equipment Inventory or Green IT menu in List mode.
- Select the Archived filter.
- To display recycled equipment:
- Display the Green IT menu in List mode.
- Select the Recycled filter.

Screens description
Consumption monitoring
By location
The Green IT > Location view displays the daily energy consumption of equipment by location.
By equipment
The Green IT > List view displays information on the energy consumption of each equipment, i.e. watts/hour and usage percentage.
Power effectiveness usage (PUE) monitoring
PUE (Power Usage Effectiveness) is the ratio of the total amount of energy used by a data center facility to the energy delivered to IT equipment, e.g. servers, storage, network. The ideal PUE ratio is 1. If the ratio is greater than 1, this indicates that energy is being used by various electrical equipment other than the IT equipment deployed by the data center.
By supplier
The Suppliers > List view displays the PUE indicator for each supplier.
By manufacturer
The Manufacturers > List view displays the PUE for each manufacturer.
Comparison of cloud service providers vs in-house service providers
The Suppliers > List view enables you to compare service providers offering cloud services with those providing in-house services, such as in-house data centers, in order to see the differences in CO2 emissions.
Define a Ratio trend to calculate the ratio between cloud and in-house service providers, with =Cloud Suppliers as the dividend and =In-House Suppliers as the divisor.
Recycling monitoring
The Green IT > List view displays information on the recycling of each equipment, i.e. recycling contractor, recycling date and discard date.
Procedures and Wizards
How to update consumption information for equipment
Step 1: Update information for the location
1. Go to the relevant location by selecting References > Directory > Locations in the menu.
2. Specify the Carbon intensity electricity (Kg) field in the Green IT section found at the bottom of the Details tab.
This value is used to calculate estimated CO2 emission from the use of equipment associated with the location.
Step 2: Update information in the Equipment Catalog
1. Go to the relevant catalog entry by selecting References > Catalogs > Equipment Catalog in the menu.
2. Specify the energy consumption in the Green IT section found at the bottom of the Details tab.
This information will be inherited by each new equipment associated with this catalog entry.
Step 3: Update information in the Equipment form
1. Go to the relevant Equipment form by selecting Asset & Configuration > Equipment > Inventory in the menu.
2. Specify the information in the Green IT: Consumption section found at the bottom of the Details tab.
The Estimated CO2 during use (Kg) field is automatically calculated. It is equal to: the Carbon intensity electricity (Kg) value specified for the location associated with the equipment * the Electricity Consumption (Watts/Hour) value specified for the equipment.
3. Click Save.
To simulate changes in energy consumption when an item of equipment is replaced by another, run the Energy Consumption Simulation wizard.
How to update recycling information
Step 1: Discard the item of equipment
1. Select Asset & Configuration > Equipment > Inventory in the menu.
2. Select the item of equipment you want to modify.
3. Run the Discard wizard.
4. Specify the information on the discarding and recycling of the equipment.
Step 2: Update recycling information
1. Select Asset & Configuration > Equipment > Green IT in the menu and display items in List mode.
2. Select the item of equipment you want to modify.
3. Run the Recycling of Assets wizard.
Note: A message will appear if recycling information was already entered using the Discard wizard. Click Yes to continue.
4. Update the information on the recycling of the equipment.
5. Click Finish.
The Equipment form will be updated.
How to use the Energy Consumption Simulation wizard
Step 1: Select the equipment to be replaced
1. Go to the list of equipment by selecting Asset & Configuration > Equipment > Inventory in the menu.
2. Select the items of equipment to be replaced.
3. Run the Energy Consumption Simulation wizard.
- The equipment to be replaced will appear in the top half of the screen. (1)
- The bottom half of the screen is used to specify the replacement equipment models. (2)
Step 2: Select the replacement equipment models
1. Select the replacement equipment models in the bottom half of the screen.
- If all of the equipment to be replaced is associated with a single location, this location will appear by default in each new replacement model row.
- If the equipment to be replaced is associated with multiple locations, the Location field will be empty by default and must be specified. The location you select will then be proposed for each new replacement model row.
2. Specify the information on the replacement models required for running the simulation.
Step 3: Run the simulation
1. Click the Compare Consumption Levels button.
- The simulation will include the total quantity of replacement models.
- The results will appear as shown below:
- In green when the replacement equipment enables a reduction in electricity consumption and annual energy expenses, as well as lower CO2 emissions.
- In red when the replacement equipment results in an increase in electricity consumption and annual energy expenses, as well as higher CO2 emissions.
