Exhibit III.6. On-Site Energy Production MeasurementPriorityBridge Gap Between Design & Performance CommissioningScopeRenewable on-site generation for new and existing commercial and residentialbuildingsTechnology Innovation or ImprovementHigh performance on-site energy production systems are being developed and arenecessary to achieve net-zero energy buildings. However, meeting the goals for net-zeroenergy buildings depends on whether the actual performance of the on-site energygeneration system meets the design predictions. Tools are needed to accurately predictsystem performance, as well as identify system problems and enable corrective actionsas needed.Measurement Science Challenges and Potential SolutionsChallenges• Sensors to monitor system performance• Models to predict system demand• Tools to project optimal performance,compare to actual and provide troubleshootingand diagnostic informationPotential Solutions• Low-cost sensor technology• Predictive performance modelingsystems• Field demonstrations of tools afterlab developmentStakeholders and RolesGovernment . . . . . . . . . . . .National Laboratories . . . .Industry . . . . . . . . . . . . . . .Standards Organizations .Trade Groups . . . . . . . . . .Academia . . . . . . . . . . . . .measurement protocols, technical assessment, andperformance modelingdevelop sensorsASTM/UL/ASHRAE (advisory)Solar/Wind Energy Association (advisory)USGBC (advisory)RELATIVE IMPACTS Low HighImproves Energy EfficiencyAccelerates InnovationEnhances CompetitivenessProvides Societal BenefitsSupports a Healthy Environment*********************************************18 Measurement Science for Net-Zero Energy Buildings
Exhibit III.7. On-Site Energy Production MeasurementPriorityDynamic In-Situ Performance MeasurementsScopeRenewable on-site energy generation for new and existing commercial and residentialbuildingsTechnology Innovation or ImprovementOn-site energy generation has the potential to reduce the burden on centralized powerplants and enable greater use of distributed generation systems. However, accuratedata on the in-situ performance of renewable energy systems (wind, solar, geothermal)is needed to enable more widespread use in buildings. Capturing and accuratelymonitoring the real-time actual performance of energy production systems will alsoensure that proper credits are given toward achieving net-zero energy buildings goals.Measurement Science Challenges and Potential SolutionsChallengesLow-cost, durable technology:• Sensors (module level)• Wireless communication betweensensor and monitoring system• Ability to measure solar irradiancePotential Solutions• Identification and assessment ofsensor and communicationtechnologies that may beapplicable• Lab demonstrations and limitedfield demonstrationStakeholders and RolesGovernment . . . . . . . . . . . . . .National Laboratories . . . . . .Industry . . . . . . . . . . . . . . . . .Private Research Institute . .Standards Organizations . . .Trade Groups . . . . . . . . . . . . .Academia . . . . . . . . . . . . . . . .measurement protocols; technical assessment; testmethodsdevelop sensor technologypossible involvementASTM/UL/ASHRAE (advisory)Solar/Wind Energy Association (advisory)possible involvementRELATIVE IMPACTS Low HighImproves Energy EfficiencyAccelerates InnovationEnhances CompetitivenessProvides Societal BenefitsSupports a Healthy Environment*************************************Measurement Science for Net-Zero Energy Buildings 19
