Data Center

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

Data Center

Data Source: EPA Data Collection with Industry

Dependent Variable: Power Usage Effectiveness (PUE)

Independent Variable: Uninterruptible Power Supply (UPS) Source

Energy

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

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

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

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 not sub-metered. • Facility has no UPS meter• IT Energy is not metered – Apply Estimates

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)

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

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)

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

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)

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

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

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

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)

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

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?
