The role of simulation in support of Internet-based energy services

Predictive control techniques for energy and indoor environmental quality management in buildings

“…Predictive control in conjunction with BEMS on the other hand uses a model to estimate and predict the optimum control strategy to be implemented [6]. While the online control systems can react only to the actual building conditions [7], a model-based predictive control can move forward in time to predict the buildings' reaction to alternative control schemes.…”

Studies into the use of building thermal physics to inform design decision making

“…The generally limited and fragmented education in building thermal physics 7 together with a lack of tools to support design decision making, pushes the 4 A list of references for strategies that focus on creating collaborative environments can be found in Bleil de Souza [1]. Further examples can also be found in Augenbroe et al [15], Clarke et al [16], Prazeres et al [17], Donn et al [18], Reinhart et al 2011 [19], to cite a few. 5 A list of references for simple generative forms or genetic algorithms can be found in Bleil de Souza [1].…”

Internet Based Energy Services During Cooling Season

“…The neural network models, are executed on line, and estimate the cooling energy consumption the next 24 hours, on an hourly base [3,15,16]. The set of inputs consist of past values of AirConditioning power consumption, the minimum and maximum ambient temperature of the previus day, and a set of calendar variables and variables associated with occupancy [15,16]; the occupancy of the building has a strong effect on the energy use, and whether the building is in sesssion or not is important.…”

“…Service Providers and end-users access the services through standard Web browsers and information and/or control actions may be transmitted back to the end-users. The system overview is described in detail in [3]. This paper presents a set of such services, tested and prototyped in Greece.…”

In the framework of the project, a range of new energy services was defined and tested within field trials in Czech Republic, Sweden, Greece and UK.…”
