Green Computing at RIT

Reducing Computer Energy Usage

• Current Practices at RIT
• Goal of Project
• Trial Overview
• Trail Setup
• Trial Results
• Recommendations
• Questions & Answers

• No campus-wide PC power policy
• Each department has its own policies which is confusing and inefficient
• Most computers stay on 24/7
• Whether or not they are in use

• Assess current energy usage policies
• Decrease power consumption

• NRH Computer Lab chosen for trials
• Easily Managed by ITS
• FMS Installed Power Monitors
• Worked with ITS & FMS

• 15 Dell Quad Core Desktop PCs
• Week 4-7 : baseline testing
• No sleep, WCG after 10 minutes
• Week 8-11 : reduced power testing
• S3 sleep after 20 minutes
• Everything else the same

• Reduced power consumption by 66%
• Extrapolate data to computer labs
• ITS Estimates 1600 Windows Based Desktops in the RIT Computer Labs
• Potential savings of $20K to $60K a year
• 186 Metric Tons of CO2 avoided OR same as burning 20,800 gallons of gasoline

• Implement a campus wide computer sleep policy
• Computers shouldn’t be on when not in use
• Require new computers to be Energy Star certified
• Reduced power consumption during sleep
• Have a central organization or individual in charge of grid computing projects
• Currently grid computing projects are not centralized
• Centralized grid would increase efficiency and PR
