in-house review of EMIS analysis and reportingto identify issues, implementing a managementprocess for taking action to correct issues, and usingthe EMIS to document energy and/or cost savingsLESS COMMON MBCx ACTIVITIES: Staff oroccupant recognition for energy savings efforts,and an EMIS training program for in-house staff tomaintain ongoing energy management processesWhile the data inputs to EMIS are generallya combination of 15-minute and hourly data,EMIS outputs can be reviewed by staff as varyingfrequencies based on need. Figure 6 shows that FDDusers most commonly review the outputs weekly,whereas EIS users most commonly review outputsmonthly or daily. The EIS was often used both toconduct daily electric load analysis and to prepare formonthly energy team meetings and reports.While a review frequency of daily or weekly isdesirable to benefit from the real-time results ofanalytics, constraints on operations and maintenance(O&M) staff time may lead to monthly review, eitherin-house or through an MBCx service provider. Sincenotification of emergency-type faults are generallyavailable through the BAS directly (e.g., a chiller isoff-line), the issues found through an FDD may notbe urgent from a safety and comfort perspective. TheFDD software can assess the severity of the faultsand determine how long they have occurred, so thatresponses can be prioritized for whatever frequency ofaction is desired.3. FINDINGS3. SMART ENERGY ANALYTICS CAMPAIGN RESULTSFIGURE 6: Frequency of EMIS review byEMIS type(n = 61)EISFDD25Number of ParticipantsASO is not yet prevalent in the market generally, andwas implemented by only two Campaign participants,and they also had EIS and/or FDD installed. We do notreport costs or savings for ASO since there are onlytwo data points.EIS functionality was most utilized by energymanagers. Organizations with both FDD and EIStended to focus on the FDD functionality due tothe detailed recommendations provided. The FDDimplementations that integrated meter data analyticswere categorized as EIS + FDD in Figure 5 (previouspage). However, since the software applications wereprimarily FDD solutions, we have combined the FDDand EIS + FDD categories for the cost and savingsanalysis in the remainder of this report. Campaignparticipants implemented products from 40 differentEMIS vendors, which points to the breadth of producttype covered by this study.Most organizations needed fewer than six monthsto install and configure theirParticipantsEMIS. A few organizationsimplementedexperienced significant challengesproducts fromgetting meters connected andcommunicating, with multiple40 differentyears required to get all the issuesEMIS softwareresolved and the EMIS in use.providersFor example, a large campusmay be integrating meters and sub-meters for multiplefuels (electric, natural gas, chilled water, hot water,steam), with many different meter vendors andvintages across the campus.The use of data and software in combination withan overarching defined energy management processis critical in realizing the value of EMIS. Almost allorganizations had an energy management teammostly made up of facility engineers or techniciansand energy managers. The energy managers tendedto lead the analysis process, sometimes supportedby a consultant or service contractor. Just over halfthe organizations contracted with a service provider tosupport their use of EMIS, and more than half of theenergy management teams used a formalized MBCxprocess that included continuous analysis (rather thanperiodic review).The participating organizations that implementedMBCx provided information on their scope of activities:FDDEIS20151050COMMON MBCX ACTIVITIES: Commissioningthe EMIS to verify data accuracy and configuration,Berkeley Lab | Proving the Business Case for Building Analytics78Daily161093MonthlyQuarterly5Weekly3EMIS Review Frequency18
