- This paper presents interim results of the currently ongoing "Building as a Service" (BaaS) EU project. The BaaS project aims at optimising energy performance of non-residential buildings, e.g. schools, universities, hotels, shopping centres, or sports facilities.An ICT platform is being developed that integrates IT systems that already exist in infrastructure assets with new IT components delivering novel functionalities extending the performance assessment of buildings. The former include building management systems (BMSs), access control systems, or systems providing weather data. The latter are mostly concerned with the assessment, prediction, and optimisation (APO) of energy usage and modelling. The IT infrastructure systems and APO services are linked by an integration middleware. The main features of this middleware are standardised interfaces via which all communication between the components of the system is routed. Functioning and characteristics of the middleware and its interfaces will be explained in the present paper.

Conference paper (peer-reviewed)abstract
- n the present paper, the control design of Heating, Ventilation and Air Conditioning (HVAC) systems is investigated. In large-scale buildings – e.g. hotels or hospitals – the high dimension of the control design problem precludes a solution with reasonable computational effort. In this paper, a distributed control strategy is proposed, where interacting agents are operating sub-systems; interaction between these agents can ensure that an optimum solution can be obtained. A novel method to distributed control is introduced based on data-driven modeling where the strategy is not based on explicit optimization, but on weighted learning of the control rules; two examples of the addressed system are formulated. A significant advantage of the proposed approach consists in minimal assumptions on the addressed system and the most significant disadvantage is the need of sufficiently rich data-sets.

Conference paper (peer-reviewed)abstract
- For today's building operation business, intelligent building performance analysis solutions with the strength for high replication potential are on urgent demand. While ICT is available throughout today's daily life, it is however still a challenge to bring the right data at the right time to the right decision makers in order to impact energy efficiency and savings for buildings, while operating in a highly competitive market place. With a multitude of BMS solutions and their proprietary performance calculations approach in the market, improvement of Building Performance needs to address other data sources as well, like geometric data, weather, occupancy, building services, and control/actuation data. These diverse data sources ask for an integrating ICT solution for data acquisition, storage, and analysis contribute to Building Performance calculations with emphasis on Key Performance Indicators (KPIs). Accommodating such information exchange demands the services of an effective and efficient middleware. This paper provides the description of an integration middleware and discusses relevant complexities experienced through achievements concerning the EU FP7 CAMPUS21 project.
