The increased focus on reduction of greenhouse gas emissions can be achieved in part by interactively integrating residential electricity production from renewable resources while giving customers incentives to shift and reduce electricity consumption during times of production with high CO₂ emissions. In this paper we present the Active House deployment architecture in the smart grid, which has been designed based on open standards. Instrumental to the design of the deployment architecture are the Royal Seaport Smart Grid sustainability and environmental requirements; the impact of these requirements on the Active House deployment architecture is discussed. We discuss the standards of relevance for the Active House project including information on ongoing standards work. We demonstrate the proof-of-concept of the applicability of the architectural solution by referring to the results of an industrial demonstrator that was exhibited at the ELFACK congress in May, 2011.
