- 7. Server consolidation Server virtualization helped us reduce the number of physical servers and lower energy costs
- 8. Other actions Replace desktops (110 watts) w/ Thin Clients (17 watts) Use power switch timers to turn off printers at night, consolidate ratio of printers to staff, and use default duplex printing on all printers

- Community IT Innovators – CITI: We help nonprofits, associations, and other social mission organizations build their organizational capacity by building their technological capacity. We help transform organizations by offering services in network infrastructure support and IT management, strategic technology planning and consulting, web and database development, and online strategy. Virsant, a subsidiary of Community IT Innovators, is a Green IT consultancy with a developing expertise in designing and deploying desktop computer power management solutions. Community IT Innovators assesses its success as a company based on the triple bottom line of people, planet and profits. CITI's business model places top priority on enabling the missions of our clients, sustaining our environment, and investing in employees' lives in a way that enables them to go out and serve their own life's mission much more effectively.
- In assessment can use power measuring devices to understand energy usage. Consolidating ratio of printers to staff
- 3 rd floor has server room and PC’s, not Thin Clients 4Q 2008 we had completed server virtualization 1Q 2009 implemented desktop power management + this was highest heat consumption (winter months)
- We were already aggressive behaviorly before implementing the changes, staff were already conscious of using less energy, and we increased that education + we decreased our per staff member load even though we raised headcount. If have 10% growth, would expect to increase energy usage by $1000 / year, however we didn’t, and that $1000 combined with $1600 annual savings we have $2600 in adjusted savings

- Num of seats Current cost -> w/ DPM 500 -> $30,000 ->$15,000 2500 $150,000 ->$75,000 Based on $60 avg energy cost to power one PC annually
- Virtualization – This is a technology that enables several servers to run “virtually” on one piece of server hardware. It lowers costs by reducing the number of servers that have to be purchased. Not only is this good for your budget, it is also good for the environment. Virtualization reduces power consumption and heat production since one server not only uses less power, it takes less power to keep cool. It is a more efficient use of hardware, which reduces the environmental impact from the production and disposal of additional hardware.
- Thin Clients – Thin Clients are small devices with a connection for a keyboard, mouse and monitor that are used in lieu of desktop computers in a network that has a terminal server or virtual desktop environment. They provide financial and environmental advantages to an organization. Thin Clients have little processing power, and instead rely on a powerful terminal server. Thin Clients generally cost about $400 (wireless and notebook versions cost slightly more) and don’t have to be reconfigured or replaced when the terminal server or virtual desktop is upgraded.Our timers are set to turn off printers at night at 9 p.m. and are available again at 5:30 a.m.
- We purchase only ENERGY STAR qualified products and EPEAT Gold, beginning 4Q 2008 started to ensure all new purchases of computer equipment are EPEAT Gold. Thin Clients do not have an ENERGY STAR rating ENERGY STAR® printers "sleep" or power down when not in use. Printers that comply with ENERGY STAR® requirements can cut energy use by 60 percent and may realize additional savings on air conditioning and maintenance. Revamped our Green Metrics to include measures we had not been tracking, and established baselines and goals for each. What we use for 2009 is attached. Established Green policies, which we had not done before.
