The cooperating companies, Meazon and GPM, will use their energy monitoring and analytics platforms to provide LAR with historical raw energy measurements of basic building equipment. Both companies will exchange knowhow and utilize their advanced own products (i.e., gateways and units) for measurements in this project. Furthermore, on the one hand, Meazon and LAR will closely collaborate to deliver an expert FDD analyser to detect and diagnose faults related to common building equipment and to propose fixes and workarounds, and on the other hand, GPM and LAR will fruitfully cooperate to deliver an HVAC system optimizer to increase comfort, reduce energy costs and shift peak demand. Finally, all partners together will join forces to deliver a maintenance expert to predict future maintenance needs on basic building equipment with the view of further optimizing its operation across time.
