provide the glue that enables the monitoring/control of those devices either remotely or manually • Communica8on is done through dedicated sensor networks, in a decentralized fashion
and basic hardware controllers enable data gathering and actua8on over a building • A centralized management system, collects that informa8on and provides ac8onable data to facility managers
are vendor-‐specific and based in puRng control logic inside hardware controllers • Energy Efficiency Techniques programmed directly on hardware controllers are difficult to manage and update • There is no literature documen8ng a framework for energy efficiency techniques through soVware
create an hardware-‐independent framework enabling development of applica8on for buildings? • Can such framework enable the deployment of energy efficiency applica8ons for mul8ple buildings? • Such framework would allow provider independence, thus abolishing vendor lock-‐in prac8ces
known, therefore the variability of applica8on needs are low! • Middleware for BASs exists, but they are merely means to achieve actua8on and sensing over devices • There is a lack on the literature regarding the documenta8on of a framework for BEMSs

to implement EE techniques, soVware is more flexible and is easy to update • EMSs provide closed solu8ons, promo8ng vendor lock-‐in and are not documented in literature • To the best of our knowledge there is a gap in the literature regarding a framework for implemen8ng EE techniques through soVware • We did our best to assess our solu8on technically, prac8cally and theore8cally
