7. Data Center

8. Data Center • New rating for data center • Rating is for spaces specifically designed and equipped for high density computing (server racks, data storage silos, etc) • Typically facilities with an Uninterruptible Power Supply (UPS) • Usually have dedicated cooling systems • May include: traditional enterpriser services, on-demand enterprise services, high performance computing, internet facilities, hosting facilities • Applicable for free standing data centers • Applicable for larger buildings with data centers • Is not for • Computer training classrooms • Closet with LAN server

9. Data Center • Data Source: • EPA Data Collection with Industry • Dependent Variable: • Power Usage Effectiveness (PUE) • Independent Variable: • Uninterruptible Power Supply (UPS) Source Energy

10. Data CenterWhat is PUE? • How is PUE computed? • Power Usage Effectiveness = Total Energy/IT Energy • What does PUE describe? • Measure of infrastructure efficiency • Captures how much cooling and support energy is required for the IT equipment • Does not capture IT equipment efficiency • Why use PUE? • Best available whole building measure at this time • How is a rating computed? • Express ratio (Total Energy/IT Energy) as an ENERGY STAR 1-to-100 rating • Each point on rating scale equals 1 percentile of performance

11. Data CenterHow to measure PUE? • Total Energy • Simple – from utility bills • IT Energy • More complex – wide variety of equipment and metering configurations • Meters closer to the servers (e.g. measure the line going into each server), closest to pure IT load • Meters further from servers include loses in power supply, transformers, etc. • Industry experts with sophisticated operations would prefer the closest measure possible • ENERGY STAR needs to select the measure that is most commonly available (easiest) to maintain broad applicability  EPA will measure IT at the UPS Output

12. Data Center Layout Other IT (e.g. storage silos) may be on PDU Mechanical Cooling System, Building Lighting, and Non IT loads Server Server Server Server Server PDU Utilities (All fuels) Server UPS System PDU Server PDU Server Typically there are transformers onsite before the UPS Server Server Server Server A B C D E F

13. Data CenterHow to Measure PUE • PUE = • PUE = Total Source Energy/Source Energy at UPS Output • PUE = A/C • Exceptions will be allowed for • Facilities with no UPS system at all • Facilities which actually run other non-IT loads off of the UPS system • Complete Guidance to be available with Portfolio Manager Help

14. Data CenterInputs • Floor Area • IT Energy Configuration (dropdown menu) • Assess how the Uninterruptible power supply is used and determines how IT Energy must be entered • Uninterruptible Power Supply (UPS) Meter supports only IT Equipment (preferred) • UPS Meter includes non-IT load of 10% or less • UPS Meter includes non-IT load greater than 10%. Non-IT load is sub-metered. • UPS Meter includes non-IT load of greater than 10%. Non-IT load is notsub-metered. • Facility has no UPS meter • IT Energy is not metered – Apply Estimates

15. Data CenterInputs • IT Energy Configuration (continued) • IT Meter requirements display based on IT Energy Configuration • Meter required at either the UPS Output or PDU Input • Many users may need to install new energy meters for IT • Last option is to apply estimates • Intended for buildings with no IT meter • Only permitted for 2 years (until June 2012), after which IT energy measurements are required • Can only be applied to buildings with data centers whose square foot is less than 10% of the total energy • Are permitted for label applications (until June 2012)

16. Data CenterScreen Mock-ups • Final screen shots not yet available • Rough mock up (not for use in trainings yet)

17. Data CenterInputs • IT Energy Meter(s) • Functionality similar to energy meters • Enter monthly energy readings • Display in separate table on the Space Attribute Page • Must be entered in kWh (energy not power) • Can define both UPS Output and PDU Input meters • Type of meter that is required is identified based on IT Energy Configuration • No limit on number or type of meters • Cooling System Redundancy • Optional variable, dropdown selection • IT Equipment Redundancy • Optional variable, dropdown selection

18. Data CenterScreen Mock-ups • Final screen shots not yet available • Rough mock up (not for use in trainings yet)

19. Data CenterSummary Facts • Data Centers now eligible to earn the ENERGY STAR • Rating and label are for a whole building • A building with a data center should earn a single rating • It is not necessary for a building to sub-meter a data center to earn a rating • Rating is based on PUE • Power Usage Effectiveness • Total Source Energy/IT Source Energy • IT energy measured at the UPS Output • Some buildings will have to install new IT energy meters • These buildings will be allowed to use estimated values until meters fully installed • Estimates only permitted for up to two years (June 2012)

20. Office and Retail • Minor model adjustments based on additional analysis of CBECS and Portfolio Manager • Used to ensure appropriate ratings for buildings with higher values for certain characteristics • Larger office buildings • Offices with high PC Density (PCs per 1,000 ft2) • Retail Stores with high cash register density (registers per 1,000 ft2) • Part of EPA’s continuous analysis to improve ratings • Overall small changes • Score changes will be less than 2 points on average

21. Water and Wastewater Treatment Facilities • Meter Functionality to Enter Monthly Flow • Applies to • Average Influent Flow in Wastewater Treatment Plants • Total Average Flow in Water Treatment & Distribution Utilities • Water meter functionality will be similar to energy meter functionality • Will appear with space attributes • Each facility can only have 1 flow meter • New Standard View • Performance: Water/Wastewater Treatment Facilities • Current Rating • Average Flow (MGD) • Current Weather-Normalized Source Energy per Flow (kBtu/gpd) • National Average Source EUI (kBtu/gpd) • Current Site Electric Use (kWh) • Annual Energy Cost ($) • Current Total GHG Emissions (MtCO2e)

22. Additional Changes • Parking Garage • Correction to a minor defect identified in the calculation methodology for open parking lots • Default Values • Portfolio Manager will display values for default attributes • Currently just indicates “default used” • Starting in June will show the actual value for that facility and attribute • Other-Distribution Center • Distribution Center will be removed from the list of Other space types • This space is covered under Unrefrigerated Warehouse • All buildings currently classified as Other-Distribution Center will be reclassified into Unrefrigerated Warehouse • A rating will be computed with default values

23. Upcoming Minor Enhancements/Announcements

24. Upcoming Minor Enhancements/Announcements • SEP Data Storage • Snap-shot more information when an SEP is generated • Will make SEP and data-checklist linked • When viewing an older SEP – correct/matching data checklist • Energy Metering Scenarios • Designate a facility as being master metered or not • Intended for malls, multifamily and other multi-tenant buildings • Specify energy totals as: • Whole building energy consumption • Common area energy consumption only • Tenant energy consumption only • Other • Ability to view meter scenario with Create View or Custom Report • Details and timing still under development

25. Upcoming Minor Enhancements/Announcements • Architects • Registered Architects (RA) are now permitted to stamp/sign an SEP for the ENERGY STAR • Increasingly greater role for RAs from design through building occupancy • RAs undergo specialized training and certification • RAs are subject to ethical guidelines in use of their stamp/seal • Refer to new guidance document • Label Application & Site Visit • Critical component of label review process • Physical inspection must be completed • PE/RA may elect to send a representative to perform site inspection • PE/RA is still responsible for stamping/certifying building conditions • Refer to new guidance document

26. Upcoming Minor Enhancements/Announcements • Terminology Change • Preference for the term ENERGY STARScore • A building receives a score on EPA’s ENERGY STAR energy performance scale • Terminology change for brand consistency • Only qualified products are called ENERGY STAR Rated • Any building can earn an ENERGY STAR score • Gradually changing guidance and terminology • Begin to introduce this language into trainings • Look for official guidance document from EPA (coming)

27. Upcoming Minor Enhancements/Announcements • Office Occupancy (review) • More than 50% average occupancy required for Offices in order to earn the ENERGY STAR label • If a building averages more than 10% vacancy for the 12-month period of assessment, the user is required to enter the vacant space separately in Portfolio Manager (PM) • If occupancy changes over time, square footage can be reallocated between the vacant and occupied spaces using the “Update” function • If any previously entered data is not consistent with the occupancy rules, use the “Correct” function

28. Upcoming Minor Enhancements/Announcements • Office Occupancy (review) • Guidance for Entering Vacant space in PM: • Number of Workers = 0 • Weekly Operating hours = 0 • Number of Personal Computers = 0 • Percent Heated = As experienced in the vacant space • Percent Cooled = As experienced in the vacant space • Some Available FAQs • How do I determine Weekly Operating Hours for my multi-tenant building? • How do I account for my office building’s vacant space in Portfolio Manager? • Can I apply to earn the ENERGY STAR plaque for an office building that isn't 100% occupied? • What would you use for occupancy level if it fluctuates?
