7 March 2011 Senior Care Facilities  Senior Care Facility definition  Buildings that house and provide care and assistance for elderly residents  Skilled Nursing Facilities (with or without Dementia Care)  Assisted Living Facilities (with or without Dementia Care)  Current category: Other – Health Care: Long Term Care (Nursing Home, Assisted Living)  Buildings will be converted to Senior Care Facility  Default values will be assigned for all required attributes  Notes on Independent Living  Retirement communities and independent living communities for the elderly are not covered  Some Senior Care Facilities offer a mix of residential options including independent living along with some form of assisted living. More than 50% of the units in a community must be considered skilled nursing or assisted living in order to be eligible as a Senior Care Facility.  Healthcare team has created guidance document of options for mixed communities, explaining when an independent living building may or may not be excluded for the purposes of obtaining a benchmark

8 March 2011 Senior Care Facilities  Required Inputs  Gross Floor Area  Total Number of Units  Average Number of Residents  Total Resident Capacity  Workers on Main Shift  Number of Personal Computers Owned by community, not personal computers of residents  Number of Commercial Refrigeration Units  Number of Commercial Washing Machines  Number of Residential Washing Machines  Number of Residential Electronic Lift Systems  Percent of the Gross Floor Area that is Heated  Percent of the Gross Floor Area that is Cooled

March 2011 Green Power Purchases  Terminology  Change Renewable Energy Certificate to Green Power Purchase  Flexibility  Generation Method – include the ability to specify multiply types of power (for blended products)  Generation Time Period – include day/month drop-down menu so users are not confined to specific quarters Can specify future dates to enter full contract delivery period 9

March 2011 Green Power Purchases  Flexibility  Generation Location – include three options in case people do not know the Plant ID: I know the specific generation plant for this Green Power Purchase – Enables accurate calculation of avoided emissions for the part of the grid where energy has been displaced I do not know the specific generation plant, but I know the eGRID sub-region in which the green power was generated – Enables accurate calculation of avoided emissions for the part of the grid where energy has been displaced I do not know any information about the generation location for this Green Power Purchase – Will have to use a default value to compute avoided emissions – Less accuracy 10

March 2011 Green Power Purchases 11

March 2011 Green Power Purchases  Summary of green power entry requirements 12 ProductPortfolio Manager Entry On-site Installation  Onsite System Meter  Y/N for owning system RECs  No additional/separate “Green Power Entry”  Grid Purchase Meter  No ‘net’ meters – must report all energy coming from system and all energy coming from the grid. This requires a bi-directional meter to measure flow from the system into the building and onto the grid, and to monitor all flow into the building from the grid Utility Green Power  Grid Purchase Meter  Green Power Purchase Renewable Energy Certificate  Grid Purchase Meter  Green Power Purchase

March 2011 Green Power Purchases  Summary of green power accounting in calculations 13 ProductRelation to Portfolio Manager Metrics On-site Installation  Included in Site and Source Energy and Score  Onsite has lower source energy factor than Grid  Emissions of onsite are zero (if you own the RECs) Utility Green Power  Not included directly in any building energy or emission metrics  Contribute to Total Avoided Emissions Renewable Energy Certificate  Not included directly in any building energy or emission metrics  Contribute to Total Avoided Emissions

March 2011 Green Power Purchases  Technical Reference Document  New document to explain types of purchases and entry requirements  FAQs  I am purchasing green power generated and delivered by my local utility; does this improve my ENERGY STAR score? No. This has an environmental benefit (REC) that you can track separately, but does not lower the energy needs to operate the building.  How does Portfolio Manager include the electricity consumption from my building’s onsite solar or wind system when calculating my score? The energy used from your system must be reported in total and included in source and site energy. The on-site system has a lower source energy than equivalent grid purchases and therefore will contribute to a higher ENERGY STAR score.  Do I receive credit in Portfolio Manager for the export of onsite generated renewable electricity back to the grid? No. The export of energy back to the grid does not lower the energy required to operate your building. 14

March 2011 Green Power Purchases  FAQs (continued)  Does the Total Emissions value reported in Portfolio Manager reflect the emissions avoided from my utility green power and RECs? No. Total emissions reports the emissions associated with your energy use. The avoided emissions from RECs are not included but are tracked separately – these are generally separate line items in emissions reporting protocol.  Can I account for forms of onsite renewable energy other than solar and wind (e.g. biomass or landfill gas)? Not at this time.  If I do not know the resource type or location information related to a green power purchase what options do I have for inputting data into Portfolio Manager? Location: enter that the location is unknown Generation Type (solar wind, etc): consult with your provider and enter a best estimate at time of purchase. Actual values can be entered at the end of the delivery period. 15

March 2011 Data Centers  New optional IT Energy Meters  PDU Output Energy  IT Equipment Input Energy  More accurate measures of IT Energy  Measures will be available in create view and external reporting  Encouraged as a best practice for the future  Not required or used for the ENERGY STAR score 16

Energy for all non-IT equipment use, including HVAC, lighting, and plug loads Energy into building, from all fuel sources Building master meter(s) UPS Server Racks & Storage Devices PDUs Data Center PDU Input PDU Output IT (Server) Input UPS Output meter – For ENERGY STAR score

March 2011 Energy Calculations  Source Energy  Revised source energy factor to account for prevalence of CHP Steam in the market  About 40% of District Steam is CHP (more efficient, lower source factor)  Revised Source Factor: 1.21  Buildings with steam may see their scores go up  Natural Gas  The amount of heat (Btu) in 1ccf of natural gas depends on the elevation At higher elevations the atmospheric pressure is lower  Portfolio Manager used to account for this Conversion factor from ccf to kBtu depended on building’s elevation (zip code)  Most utilities already account for this and report in “standard” ccf (e.g. adjust their ccf value) or in therms Additional adjustment in Portfolio Manager is not necessary and will be removed  Approximately 35,000 building in Portfolio Manager use natural gas in a volumetric unit (e.g. ccf) The majority will have no change in score 18

March 2011 Emissions Calculations  Emissions currently unavailable (!)  Went offline on 1/31/2011  More recent factors now available from eGRID  Change in method to map zip code to utility  Emissions will return on 3/21  Most current eGRID files eGRID 2010 v.1 Complete release of data for 2007  Methodology is still consistent with standard GHG Protocol  WRI/WBCSD, DOE, EPA 19

March 2011 Weather Normalization Document  What  New technical document to explain the way that weather is accounted for in Portfolio Manager metrics  Weather Normalized EUI  An EUI that expresses the energy use a building would have used under 30-year average conditions  Available for all buildings  Compares a building to itself over time  ENERGY STAR score  Adjusted for actual HDD and CDD experienced during the 12 month evaluation period  Based on actual EUI relative to actual HDD and CDD  Evaluates a building using statistical correlations observed in the national population 20

March 2011 Automated Benchmarking Services  Read/Write Authorization  PM users will be able to have multiple ABS providers and can manage specific read/write access for each meter  Only one ABS provider can write (populate) a given meter  Multiple ABS providers can be given read access to meters  New Test Authorization Tool  Ability to test pending authorizations in the test environment  Optional Date Range for “get meter details”  Enables an ABS provider to get data for a specified time period only  Currently have to retrieve all meter data, which could be several years worth of data – change will make the service faster for ABS providers 21

March 2011 Automated Benchmarking Services  Senior Care Facilities  New energy performance scale will be available through ABS  Green Power Purchases  New entry options will be available through ABS  Campus Meters  Campus energy meters can be updated via ABS  Will work for any existing campus meters assigned in Portfolio Manager  This does not give ABS providers an ability to create campuses or change buildings on a campus  Water Meters  ABS will enable the entry and upload of water meter data 22

Data Center Announcements 23

IT Energy Estimates  Why permitted  Many mixed use buildings do not have IT meters in place  This is a grace period to enable ENERGY STAR scores until meters can be installed  How to meter  Meter at the output of the UPS  Meter IT Equipment energy only (servers, storage, network)  DO NOT include cooling, lighting, or other ancillary equipment  Meters typically will cost less than $2,000  Deadline to meter!  Estimates will no longer be available after June 2012  In order to receive a score 12 months of data are required  Meters must be installed by June 2011 to ensure an ENERGY STAR score after June

Reminders on Definitions and Policies  Data Center definition  Data Center applies to spaces designed for processing of computer loads  Facilities with rows of servers, storage and network devices  In a mixed use setting, typically more than kW of power required to run IT equipment alone (not including cooling, etc)  Closets with 2-3 servers are not Data Centers, even if a supplemental cooling unit is required  IT Energy Use definition  Report use of the IT Equipment only Should not include any cooling equipment or other loads  Measure energy not power  If I don’t have the IT can I enter to total energy use (including cooling) until the meters are required in June 2012? NO – it is not acceptable to enter total Data Center energy use, the PM estimates must be applied  Building energy meter requirements  Should report all energy use including the energy use of the Data Center and its IT loads  Reporting the IT Energy Meter and including this energy in the total is NOT double counting. 25

October 2011 Release
