7. Data Center

8.  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 Center What 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 Center How 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 UPS System PDU Server A CDEF Utilities (All fuels) Mechanical Cooling System, Building Lighting, and Non IT loads Typically there are transformers onsite before the UPS Other IT (e.g. storage silos) may be on PDU B Server

13. Data Center How 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 Center Inputs  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 not sub-metered. Facility has no UPS meter IT Energy is not metered – Apply Estimates

15. Data Center Inputs  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 Center Screen Mock-ups  Final screen shots not yet available  Rough mock up (not for use in trainings yet)

17. Data Center Inputs  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 Center Screen Mock-ups  Final screen shots not yet available  Rough mock up (not for use in trainings yet)

19. Data Center Summary 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 ft 2 )  Retail Stores with high cash register density (registers per 1,000 ft 2 )  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 (MtCO 2 e)

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.  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 STAR Score  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?
