4 Commercial Buildings Energy Use Breakdown of typical office building energy consumption Cooling 25% Ventilation 15% Heating 10% Plug Load 10% Lighting 40% Mt. Airy Public Library

5 Computer Power Management Approach Step 6 - Implement Project Step 5 - Develop Appropriation Strategies Step 4 - Solicit Outside Feedback on Preliminary Analysis Step 3 - Develop Preliminary Computer Power Management and Equipment Retrofit Energy Savings Step 2 – Determine How Many Computers have Power Management Settings Enabled Step 1 - Create an Accurate Facility Wide Computer Inventory

10 Voluntary Action - Activate power management settings in all new computers. - Activate appropriate power-down feature through each PC’s operating system. - Ensure the monitor turns off after 10 – 20 minutes of inactivity. - Send out agency wide newsletters on how to voluntarily activate power management settings. - Limit screen-saver use.

11 Voluntary Action

12 Install motion sensor based power strip/surge protector. Plug all task lighting, printers, scanners, speakers into motion sensor power strip Restrict the amount of desktop printers, scanners, fax machines and task lighting.

13 Plug Load Analysis for NREL’s New Administrative Building  Chart below shows importance of reducing nighttime use (i.e. use Motion Sensor Power Strips or Plugs enabled by Light Switch)  NREL used plug load data from CBF and Cambria as reference peak plug loads Night Plug Power Density (W/ft 2 ) Day Plug Power Density (W/ft 2 ) Annual Plug Load Energy Use Intensity (kBtu/ft 2 )

14 Networked PC Power Management Networked PC Power Management programs perform the following functions: Poll computers on a network to determine each monitor and computer’s power management settings Generates reports on the result of the polling Sets appropriate power management settings on monitors and computers on the network Sets appropriate screen saver settings on monitors on the network so that users retain screen saver images

16 NREL Case Study Potential complications can arise related to internal and external devices not responding correctly when coming out of a low power state The computer power management software programs don’t support Macs Large percentage of computers connected to external data acquisition systems Laptops and desktops need to be grouped separately Difficult to implement in an organization with a complex structure.

17 GSA Case Study Performing holistic energy efficiency, renewable energy and water conservation assessments Identify financially viable energy, water, and renewable energy projects for 11 GSA sites in the N.C.R. Develop a site specific action plan for each facility Work with the site to identify appropriation and funding strategies

18 The Bigger Picture

19 GSA Case Study – VA building Veterans Affairs Administration building Large office building with 3,900 employees Computers remain on 24/7 17-inch Samsung, LCD monitor with a standard Hewlett- Packard computer o Energy Savings:1,637,260 kWh/yr o Cost Savings:$184,044/yr o Implementation Costs$107,658 o Simple Payback0.6 years

20 ESPC/UESC Process Step 1 – Contact a Federal Financing Specialist (FFS) First point of agency contact with DOE Assists in initial project planning and coordination Initiates and coordinates Interagency Agreement (IAA) process Works closely with Project Facilitator to guide the agency through the ESPC process

21 21 FEMP Federal Energy Project Financing Specialists Western and Central states — Scott Wolf, 360-866-9163 scott.wolf@ee.doe.gov Mid-Atlantic, Midwest, Northeast states — Tom Hattery, 202-256-5986 thomas.hattery@ee.doe.gov thomas.hattery@ee.doe.gov Southeast states and technology-specific Super ESPCs — Doug Culbreth, 919-870-0051 carson.culbreth@ee.doe.gov carson.culbreth@ee.doe.gov Cross-Regional Support — Gordon Drawer, 630-584-9650 gordon.drawer@ee.doe.gov

22 Advantages of Alternative Financing Can finance projects with bundled payback periods up to 25 years Can finance multiple projects across multiple buildings under a single contract Allows for bundling of high ROI and low ROI projects into one project/contract – allows for the incorporation of more ECMs than would otherwise be possible

23 Advantages of Alternative Financing Guaranteed savings – agency appropriations are not required but can be used to buy down the initial cost of the project Primarily done if you don’t have agency appropriations to pay for the project Mitigates/shares risk associated with: o Equipment maintenance or failure o Measurement and verification of energy savings o Utility escalation rates

24 Closing Voluntary action items should be implemented first Networked PC power management programs should be incorporated into an agency wide energy conservation policy o Policy all buildings must adhere to ESPCs/UESCs can serve as a funding mechanism to implement networked PC power management programs
