This paper presents a risk-sensitive model-based plan executive, p-Sulu, as well as its application to energy-efficient room temperature control of a smart residential building called Connected Sustainable Home. p-Sulu minimizes the use of heating and cooling by optimally controlling the incoming sunlight through a south-facing facade made of electrochromic(More)
The goal of this thesis is to design an autonomous control system for the sustainable control of buildings. The control system focusses on satisfying three goals to encourage and facilitate a more sustainable lifestyle for the future: sustainability, comfort, and convenience. First, the system must be sustainable, meaning it controls the home to minimize(More)
Suppose that a target function f0: R d → R is monotonic, namely weakly increasing, and suppose that an initial, not necessarily monotonic, estimatê f is available. The rearrangement methods of [3] can be used to transformˆf into a monotonic estimatê f *. As was shown in [1], this rearranged estimatê f * is necessarily closer to the target function f0 in(More)
This paper presents a programmable façade that contributes significant reduction in energy consumption by regulating the incoming sunlight into the interior of a residential building. Electrochromic and liquid crystal technologies allow the modification of thermal transmittance and view, which are controlled by a model-based plan executive. Except from(More)
Improving the energy efficiency of residential buildings can lead in reducing the energy consumption of cities. It is presented a prototype house that uses real time connectivity to enable effective energy management through the deployment of an optimization algorithm. Following the principles of the Web of Things, the devices of the house are mapped into a(More)
