Goals1) Quantify campus plug load energy consumption2) Identify viable plug load reduction opportunities
Systemic Targeted
Project Overview
Other Partners:LBRE IT
Water group Procurement
DPMBuilding managers

Room by room physical inventory conducted by Office of Sustainability interns
Visual only Information collected on
electronic equipment and relevant attributes
Data recorded in an internally developed web application
Energy consumption estimates applied for each type of equipment based on attributes recorded
Interns trained on identifying equipment, including IT
Inventory Description

• Types of equipment included: • Standard office equipment• Personal computers• Monitors (LCD & CRT)
• Common IT equipment• Servers• Network switches• UPS devices
• Standard lab equipment• Kitchen & break room equipment• Gym equipment • Other (ex. Water fixtures and occupancy data)
• IT equipment primarily inventoried in IT closets in academic & office buildings

• Of the plug load energy consumption on campus, 34% represents achievable savings, which is equivalent to 7% of total campus electricity consumption
• Viable Sustainable IT programs alone could save 20% of the campus’s plug load electricity consumption through:• Virtualization and consolidation
of servers• Adjust computer sleep settings• Adjust large networked
copy/printer sleep settings• Replace CRT monitors with LED
monitors

Sustainable IT Plug Load Reduction Program Options
1This does not fully represent the cost of server consolidation, which is currently underway and is largely sponsored by other departments. 2Includes avoided cooling costs from server consolidation and virtualization.
Note: Refer to “Sustainable IT Plug Load Reduction Program Summary” spreadsheet for details.
All Sustainable IT programs together have the potential to save $1.6 million annually.

Office of Sustainability metrics and ratings are only estimates, especially around networking equipment
Feedback from group valuable in determining next steps Which programs make sense to implement from the perspective of your department or
school? What are some advantages and disadvantages of the programs listed that have not been
mentioned? What other viable program options might there be that have not been covered here? How else will this data to be helpful to your department/school?
Ex. Locations of computing & networking equipment How can the Office of Sustainability support Sustainable IT plug load reduction efforts? How can the Office of Sustainability support your department/school’s overall efforts?
