3. Project Overview Goals 1) Quantify campus plug load energy consumption
2) Identify viable plug load reduction opportunities
Systemic
Targeted
Other Partners:
LBRE IT
Water group
Procurement
DPM
Building managers

4. Inventory Description
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

5. Data Collection Tool
Interns used web application developed by LBRE IT to collect inventory data

6. Inventory Scope 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

12. Plug Load Savings Profile
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

13. Sustainable IT Plug Load Reduction Program Options
All Sustainable IT programs together have the potential to save $1.6 million annually.

14. Feedback
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
