Monitoring Approaches for New-Generation Energy Performance Certificates in Residential Buildings

In 2002, the Energy Performance of Building Directive (EPBD) introduced energy certification schemes to classify and compare building performances support reaching efficiency targets by informing different actors sectors. However, since its implementation, Certifications (EPCs) remained unexploited with limited impact on savings targets. this context, EPC RECAST project aims at studying a new generation EPCs focus residential sector. More in detail, paper presents frames monitoring approach based low-cost non-invasive technology for real data collection existing apartments/houses. The method is levels selected according typology (e.g., detached house, apartment), services centralized or local generation), vectors natural gas electricity). Three have been identified (named as: basic, medium, advanced) each one, plug play sensor kits selected. Six representative pilot buildings verify general and, particular, sensors’ applicability communication, reliability, platform. presented work highlights, one hand, feasibility proposed approach; other, it highlights difficulty fully standardizing sensors considering that building/apartment has specific characteristics constraints be carefully analyzed. use ultrasonic flow meters represents good technical option reducing cost plant system; however, their installation must verified logger needs powered calibrated collecting reliable data.
