1 Building Energy Quotient ASHRAE s Building Energy Labeling Program

2 What is Building Energy Labeling?

3 As the nation looks to reduce its energy use, information is the critical first step in making the necessary choices and changes.

4 Information for Consumers to Allow Educated Choices is Not New Restaurant Sanita,on Ra,ngs Nutri,on Fact Label Car Fuel Economy Es,mates

5 Cost of Owning a Building

6 A Shared Problem Most buildings will lose up to 30% of their efficiency in the first three years of opera;on. Bill Harrison, ASHRAE Presiden3al Member (Data based on Texas A&M Study)

7 Building Energy Labels: Promote energy efficiency in real estate Differen3ate efficient buildings in the marketplace (for tenants/buyers) Provide feedback on a building s designed and measured energy use Iden3fy energy efficiency measures and value in reducing long- term energy costs Add to building performance databases

8 Current Labeling Efforts Building cer3fica3on is becoming widespread Interna3onal efforts: European Union, Singapore and Canada U.S. efforts: EPA ENERGY STAR PorVolio Manager benchmarking DOE Commercial Building Energy Score (pilot phase) USGBC LEED Ra3ng Broader sustainability ra3ng GBI Green Globes Broader sustainability ra3ng BOMA 360 Six O&M focused criteria (incl. energy) State labeling and disclosure programs

10 Why ASHRAE? Why now? Over 100 years of experience in the building sciences and technology Strong technical exper3se across all aspects of building design and opera3on Historic focus on developing consensus- based, non- commercial documents Respect and credibility within the building community Opportunity to support consistent mandatory programs worldwide

11 ASHRAE s Building EQ Voluntary labeling program that draws on successful features of other building labeling & cer3fica3on programs Complements other green building and energy ra3ng/labeling programs Provides a way to benchmark performance S3mulates adop3on of high performance building techniques Allows for comparison of As Designed (asset) and In Opera3on (opera3onal) ra3ngs

12 How is beq Different? Different from Benchmark programs: Greater differen3a3on for high performing buildings and emphasis on zero net energy Expanded building categories covered via a table of median EUI values by climate zone Inden3fies opportuni3es for improved energy performance (In Opera3on) Consistent process to assess energy performance Builds a rela3onship with an ASHRAE Cer3fied Professional or licensed PE

13 How is beq Different? Different from Green Building programs: Focuses solely on a building s energy use Focused on understanding energy use Inden3fies opportuni3es for improved energy performance (In Opera3on) Allows for comparison between buildings with different opera3ng variables (As Designed) beq could serve as a consistent energy ra3ng method for both Exis3ng Building and New Construc3on programs.

14 Benefits of beq Consistent analysis of a building s designed (as built) and actual energy performance Recommenda3ons for reducing energy use with rough costs and paybacks Poten3al for con3nuous improvement in energy efficiency Ability to track and show effec3veness of improvements Demonstra3on of corporate responsibility Rela3onship with an ASHRAE cer3fied professional or licensed PE

15 beq Rating Types In Opera;on (opera3onal) ra3ng Assessment of the building s structure/ features and how it is operated Based on actual metered energy use of a building Applicable for buildings aber at least months of opera3on

16 beq Rating Types As Designed (asset) ra3ng Assessment of the building s physical characteris3cs and systems Independent of a building s occupancy and opera3ng condi3ons Based on results of a standardized energy model as compared to a baseline Applicable to both new and exis3ng buildings

17 Comparing beq Ratings In Opera;on Ra3ng: Actual metered energy use Influenced by opera3onal and occupancy variables Improved by upgrading building fabric or opera3ng procedures As Designed Ra3ng: Simulated standardized energy use Independent of opera3onal and occupancy variables Improved only by upgrading building fabric or systems

18 beq In Operation Process (EUI measured / EUI median ) x 100 Compares actual metered energy use of candidate building to median/baseline EUI Leads to informed energy management decisions Provides informa3on on building s IEQ Illustrates benefits of equipment and system investments

19 beq In Operation Features Includes an ASHRAE Level 1 Energy Audit Recommends ac3ons to reduce energy use Iden3fies both peak demand reduc3on and energy management opportuni3es Recognizes energy use from on- site renewables Uses Median EUI s developed from CBECS data, normalized for climate zone and opera3ng hours Includes measurement- based IEQ indicators to assure levels of service are maintained

20 Level 1 Energy Audit Preliminary energy- use analysis (PEA) with review of u3lity bills, rate classes, and peak energy demand Space func3on analysis and energy end use summary Iden3fica3on of low- cost/no- cost energy improvement measures with es3mated costs and savings Recommended capital improvements with es3mated costs and savings

21 beq As Designed Process (EUI standardized / EUI median ) x 100 Compares standardized modeled energy use of candidate building to median/baseline EUI Uses specified modeling inputs of building opera3ng parameters Uses ENERGY STAR Target Finder to determine median/baseline EUI Includes a table of median/baseline EUIs by climate zone for addi3onal building types

22 beq As Designed Features Isolates impact of a building s physical charac3s3cs and systems Based on an energy model that normalizes for opera3onal variables using standardized inputs and schedules Does not predict actual building energy consump3on because opera3onal and occupancy parameters aren t customized to the candidate building

23 Problems with Existing Asset Rating Methodologies Results are not comparable among buildings of the same type Occupancy parameters not normalized Impact of some physical variables neutralized Building Massing Percent of glazing below 40% Calcula3on procedures insufficiently rigorous Discrepancies between asset ra3ngs and opera3onal results misunderstood

24 The beq Rating Scale The beq scale is dimensionless Zero point on scale set to zero net energy Median value (100) set to na3onal median EUI of CBECS for that building type Score can go below zero for net energy producing buildings Bojom half of scale exceeds 100 for inefficient and unsa3sfactory buildings with high energy usage

25 The beq Rating Scale Scale Range Ra,ng Descrip,on 0 A+ Zero Net Energy 1-25 A High Performance A- Very Good B Efficient C Average D Inefficient >145 F Unsa3sfactory
