Brief description of the conference:

The Central European Symposium on Building Physics (CESBP) 2013 was held from 9 - 11 September 2013 in Vienna, Austria, at the Technical Univerity of Wien. CESBP is an excellent forum for scientists, researchers, and practitioners, not only from Central Europe, but from all over the world. Thereby, technical information, new ideas, latest developments, and future directions in the fields of Building Physics shall be presented and discussed. 

CESBP 2013 saw a great amount of Research Paper presentations from an International group within the following topics:

  • heat and mass transfer in building materials, building envelope, and whole buildings with special emphasis on models, experiments, and practice
  • buildings' energy performance
  • indoor climate and thermal comfort
  • hygrothermal performance/moisture
  • air flow and pollutants transport
  • daylight and illumination engineering
  • building and room acoustics
  • urban physics
  • environmental impact and life-cycle assessment

How to integrate energy simulation, demand prediction and Continuous Commissioning into the daily operation of buildings?



Regardless of how well designed or high performance a building is constructed it needs to be adequately correctly maintained to keep that level of performance through it lifecycle, and that is not the case for almost all buildings. A sustainability certified building will only remain such as long as it is operated responsibly and therefore Total Facility Management needs to encompass the following •Metering & Monitoring Systems •Performance Benchmarking •Integrated Building Systems (Boilers, Chillers, HVAC, CCTV, Access Control, Room/Event Scheduling, Maintenance management, Services Planning) + external data e.g. weather •Lifecycle Planning •Preventative Maintenance Building Operators need the tools and support (legislation, regulation and business models) to successfully deliver holistic building energy reduction measures…ICT renovation and integration of building systems. Current situation encourages disjointed planning and efficiency initiatives. E.g. upgrade thermal envelope components (windows, insulation, facades) often not investigated how that effects other systems and if there are changes required to building operation to compliment these changes or to further push the benefits or whether it could negatively impact other systems, can they work together.


Impacts of building performance monitoring on integrated energy management



Modern Integrated Energy Management must consider different energy sources, such as gas, electricity or steam imported from supply grids but also hot water and electricity generated from renewable energy sources and ‘harvested per building’. Technical and economical challenges need to be addressed when operating and managing integrated energy systems, such as the prediction of the availability and capacity of energy sources, the prediction of energy demand (including the user requirements) and the prediction and monitoring of services provided to building users and occupants. This paper describes an integrated monitoring and management concept to manage energy consumption of buildings and groups of buildings. The first part discusses the state-of-the-art of energy performance monitor-ing, the second part presents a performance monitoring concept for buildings and the third part discusses the expected advantages of a holistic performance management concept for integrated energy management.


Alternative ways for advanced energy management



In this paper we discuss the design and underlying rationale of the solver module for the energy management platform developed as part of the European FP7 project Campus21. The optimization module uses a declarat- ive, object-oriented description of the building management scenario. It is based on components, whose beha- vior is described by variables, constraints and objectives, and energy flows, which describe the interconnec- tion of components in the model. A special type of energy flow is the heat transfer between components, which is based on the temperature properties of the connected components. The generated model is solved with a mixed integer programming system, in our case CPLEX.

We explain the operation of the system on one of the selected demonstrator use cases in the Campus21 project, the Environmental Research Institute (ERI) building, which is part of University College Cork. The building combines a solar-thermal array, a geo-thermal heat pump, conventional gas-fired boilers with a lim- ited amount of hot water storage and an under floor room heating system. Windows are equipped with auto- mated blinds that can be used to control the solar gain to south-facing rooms.

Our approach is centered on three core design choices: We use a deterministic model, solve the model with mixed integer programming, and we have developed the complete system in Java for easy integration with the middleware components of the Campus21 platform.
