“…The Open Linked Data approach for building automation data streams is facilitated by EDWH Ontology proposed in [11]. The aim of the EDWH ontology is to provide a bridge between the SSN ontology and the W3C RDF Data Cube vocabulary, as the data are meant to be analyzed by OLAP data cube techniques.…”

Building construction has gone through a significant change with the emerging spread of ICT during last decades. Intelligent buildings are equipped with building automation systems (BAS) that can be remotely controlled and programmed. However, such systems lack convenient tools for data inspection, making building performance and efficiency analysis demanding on large sites. The paper presents an adaptation of Semantic Sensor Network ontology for use in the field of building operation analysis. The proposed Semantic BMS ontology enriches the SSN with a model of building automation data points and describes relations between BAS and physical properties of a building. Proposed ontology allows facility managers to conveniently query BAS systems, providing decision support for tactical and strategic level planning.

Building construction has gone through significant change with the emerging spread of ICT during last decades. "Intelligent buildings" are equipped with building automation systems (BAS) that can be remotely controlled and programmed and that are able to communicate and collaborate. However, BAS aim to facilitate operation of the building and do not provide sufficient support for strategic level decision support. This article presents adaptation of Semantic Sensor Network ontology for use in the field of building operation analysis. The Semantic BMS ontology enriches the SSN with model of building automation datapoints that gather operation data and describe the interconnections between BAS devices, algorithms and influenced or monitored properties of a building. Proposed ontology allows facility managers to query BAS systems in a way that is convenient for tactical and strategic level planning and that is unavailable in current state of the art systems.

“…This model is the one used by the paradigm known as OnLine Analytical Processing (OLAP), and graphical 3D interfaces, based on this method, can be created, focused on geographic and spatiotemporal data management systems [22]. Also this type of data modelling (OLAP data cube) has been successfully used to store and query real event data from sensors in smart buildings [23], where parameters such as temperature, humidity, luminescence and related events can be stored in a cubic cell that registers date, device and value related with the considered parameter. Even if OLAP data cubes provide a powerful tool to interact with information, their interfaces rely on 2D representation and traditional input devices, which reduce the level of effective interaction.…”

Abstract. The use of natural interfaces improves significantly aspects related to human-computer interaction and consequently the productivity and the overall performance. In this paper we present a novel framework to interact with data elements presented in a 3D space. The system provides two mechanisms to interact using 2D and 3D gestures based on data provided by Kinect and on hand detection and gesture interpretation algorithms. The proposed architecture is analysed indicating that 3D interaction with information is possible, and provides advantages over a 2D interaction over the same problem. Finally, two sets of experiments were performed to evaluate 2D and 3D interaction styles based on natural interfaces focusing on traditional interaction with 3D databases.
