2 I. Overview WHAT IS BENCHMARKING? Energy benchmarking is the prcess f measuring a prperty s energy use ver time. The prcess invlves cllecting prperty characteristics and energy cnsumptin, entering data int the Energy Star Prtfli Manager nline platfrm, and generating an Energy Use Intensity value fr the prperty. WHAT IS ENERGY USE INTENSITY? Energy Use Intensity (EUI) signifies the amunt f energy a building cnsumes per square ft per year. EUI is measured in thusands f BTUs per square ft per year (kbtu/ft 2 /year). EUI is used as a universal metric t cnvey energy perfrmance apples t apples fr all building uses and types. There are tw types f EUI: site and surce. Site energy the amunt f heat and electricity cnsumed by a building as reflected in utility bills is used t calculate site EUI. Surce energy which accunts fr lsses incurred in the strage, transprt, and delivery f fuel t the building is used t calculate surce EUI. High perfrming buildings seek t achieve EUIs that are significantly lwer than the average EUI fr their prperty type. Fr instance, the Burlingtn 2030 District uses a reginal set f EUIs fr diverse building types t establish energy reductin gals. WHAT IS THE ENERGY STAR SCORE? Frm Energy Star: The Energy Star Scre is a value which helps prperty wners understand hw their building s energy cnsumptin measures up against similar buildings natinwide. A scre f 50 represents median energy perfrmance, while a scre f 75 r better indicates that the building is a tp perfrmer and may be eligible fr Energy Star certificatin. T calculate Energy Star scre, the cnsumptin f each type f energy must be expressed in a single cmmn unit. Energy Star emplys surce-site ratis fr different energy surces t cntrl fr the efficiencies f utility prviders at a natinal level. PURPOSE OF BENCHMARKING An wner cannt cntrl what they d nt measure, and benchmarking is the first step in the energy management prcess. By gaining insights int energy cnsumptin trends, prperty wners can better understand hw well their prperty is perfrming ver time, as well as relative t similar prperties. Measuring and gaining awareness f a prperty s energy use leads t mdest reductins in energy use. In a recent study, the U.S. Envirnmental Prtectin Agency fund that buildings that were cnsistently benchmarked reduced energy use by an average f 2.4% per year, fr a ttal savings f 7%. While measuring energy cnsumptin is imprtant, benchmarking results can inspire wners t take actin and infrm next steps that can prvide further energy use reductins. By cntinuusly benchmarking a prtfli f prperties and tracking prperty EUIs and Energy Star scres, an wner can: Establish baseline energy perfrmance Cmpare similar buildings in their prtfli Infrm perfrmance gals and energy management plans Cmpile and track cnsumptin ver time Identify the best candidates fr efficiency investments Priritize energy efficiency investments Track the impact f efficiency imprvements Page 1 Burlingtn 2030 District Energy Star Prtfli Manager Training

3 II. Required Infrmatin Befre lgging int Prtfli Manager, prepare data by gathering the fllwing infrmatin abut the prperty. Prperty Backgrund Detailed characteristics f a prperty help define the peer prperty Prtfli Manager will use t cmpare against the prperty. These details include:! Prperty name & address! Year prperty cnstructin cmpleted Prvide base year and date f any majr additins r renvatins.! Primary prperty use type If the prperty has multiple uses, chse the use that ccupies the greatest percentage f the prperty Special uses may have relevant questins, such as: " Number f cmputers (fr ffice spaces) " Number f cash registers (fr retail spaces) " Number f walk-in refrigeratrs / freezers (fr grcery spaces) " Details abut cking facilities (fr cafeteria spaces)! Operating hurs If different space uses have different hurs, use perating hurs fr the primary prperty use type! Grss flr area Ttal prperty square ftage, measured between the utside surface f the exterir walls f the building Include in GFA: lbbies, tenant areas, cmmn areas, restrms, elevatr shafts, stairwells, etc. D nt include in GFA: exterir spaces, balcnies, patis, exterir lading dcks, driveways, cvered walkways, etc.! Percent f rentable flr area ccupied! Percent f prperty that can be heated Optins include: nt heated / less than 50% / mre than 50%! Percent f prperty that can be cled Optins include: nt air cnditined / less than 50% / mre than 50%! Ttal number f wrkers n main shift Includes building ccupants / emplyees / visitrs If prperty ppulatin fluctuates, use the weekly average Nt a ttal, but rather the average number f ccupants that are present in the building at the same time! Square ftage f n-site parking If n-site parking lighting r HVAC system pwer des nt tie int the prperty s meter, skip this step Separate parking areas int pen / partially enclsed / cmpletely enclsed Verify if supplemental heating is supplied t enclsed parking areas Where can this infrmatin be cllected? A helpful tl fr getting this infrmatin in ne place is the Burlingtn 2030 District Prperty Owner s Survey, sectins II and III. Hw many prperty use types shuld be chsen? The U.S. EPA recmmends selecting as few use types as pssible by chsing the prperty use(s) that describe the verall functin f the prperty. Frm Energy Star: Sme prperties include multiple use types, such as restaurants in htels, salns in senir care cmmunities, and cafeterias in hspitals. As a general rule, if a certain use cmmnly ccurs in the type f prperty being benchmarked, d nt break it ut as a separate Prperty Use Type. Simply include its square ftage with the building s primary use. Page 2 Burlingtn 2030 District Energy Star Prtfli Manager Training

4 Energy Histry A lk back at energy usage is necessary fr an accurate and infrmative benchmark. 2+ years f data is helpful t start with; wners gain mre insights n year-ver-year EUI trends. If that is nt pssible, gather at least 13 full mnths f data; withut this amunt f data, the prperty will nt receive an Energy Star Scre. It is recmmended t tabulate this infrmatin in a spreadsheet. Prtfli Manager allws fr bulk uplad f cnsumptin data (see Prtfli Manager Prcess: General step #14 n page 4 f this dcument fr mre infrmatin).! Electricity cnsumptin Ensure that usage includes nly the prperty in questin; data frm meters that track usage fr multiple buildings must be separated! Natural gas cnsumptin! Alternative fuels cnsumptin (see Figure 1 fr list f fuels)!

6 IV. Prtfli Manager Prcess: Campus T create a benchmark fr a campus f buildings with a shared central plant r a grup f buildings that are nt submetered, a slightly different prcess is required. Much f the general steps abve still apply. The different steps are prvided belw: See the Resurces sectin n page 6 fr mre infrmatin abut creating benchmarks fr campuses. 1. Create a Parent prperty. Enter infrmatin abut the Parent prperty as a whle. Aggregate the grss flr area and ccupancy percentage values t accunt fr the ttals acrss all buildings n the campus. 2. On the Hw is it used? page, enter building use details. 3. T add Child(ren) t the Parent prperty, navigate t the Summary tab f the Parent prperty. Click the Add a Building buttn. 4. Prperty details in the Enter a New Building sectin. 5. Add meters as applicable. 6. Meter data as described in the Prtfli Manager Prcess: General sectin n page 4. V. Benchmarking Results & Reprts INTERPRETING BENCHMARKING RESULTS Once all meter data has been entered and required prperty characteristics have been prvided, the Summary tab f Prtfli Manager will nw display an updated Metrics Summary fr bth the building s Energy Baseline and Energy Current mnths. These tw snapsht mnths can be edited by clicking the pencil icn t the right f the clumn header. Belw is a list f sme things t lk fr: An Energy Star Scre f less than 75 indicates that the building is nt perating like a high perfrmance building. If the Change clumn fr EUI shws text in red, this signifies an increase in energy use frm Energy Baseline t Energy Current. If the prperty des nt have an assigned Energy Star Scre, there culd be t many prperty use types assigned r the building may be utside f minimum/maximum threshlds fr prperty use details. If there is a bx t the left f the prperty s Energy Star Scre that says, Nt eligible t apply fr Energy Star Certificatin, the prperty s meter data may be ut f date r des nt cntain 12 full mnths f data. CREATING BENCHMARKING REPORTS Exprting benchmarking results and data f interest is easy in Prtfli Manager. Frm Energy Star: Fr a cllege parent prperty yu can enter just ne prperty use: cllege/university, yu d nt need t add separate prperty uses fr ffice, drmitry, library, etc., even if yu will add separate buildings fr them. Navigate t the Reprting tab at the tp f the screen t chse frm nine reprt templates created by Energy Star. Select Generate New Reprt frm the Actin drpdwn menu t create new reprts. Select the View Current Reprt drpdwn ptin t see chsen data in a table frmat n Prtfli Manager, r ne f the Dwnlad ptins t exprt chsen data t Excel.
