ECPPM 2012 - July, 2012 (5 contrib)

Title of the Conference/Workshop: 9th European Conference on Product and Process Modelling

Location: Reykjavik, Island

Dates: 25 - 27 th July 2012


Brief description of the conference:

The European Conference on Product and Process Modelling (ECPPM) is a biannual conference series dating back to 1994. ECPPM was the first BIM conference founded on the basis of European BIM research projects  preceding IFC and BuildingSMART and has fostered BIM development over the last 18 years. The conference series has gained a recognized position as an important event in the international AEC/FM ICT research agenda.


Although with European roots, the ECPPM attracts delegates and prominent speakers from all around the world providing delegates with valuable knowledge and discourse on latest state of the art in ICT research and development in the AEC/FM industry.

Realization of ICT potential in improving the energy efficiency of buildings: the CAMPUS 21 project


This paper reports on an ongoing project (CAMPUS 21), which explores the potential of integrated security, control, and building management software systems in improving the energy efficiency of buildings. The project involves participants from both academic institutions and industry and is supported by the European Union. The main objective of the project is to explore the possibility of comparing the energy and indoor-environmental performance of a number of existing facilities before and  after the implementation of monitoring-based control improvement measures.


Building data visualization using the open-source MOST framework and the Google Web Toolkit


This paper proposes a framework to simplify platform independent graphical user interface development for building data visualization. By abstracting different building data streams, consistent data access is possible. Various components are provided to simplify user interface development. Exemplary modules show the usability of the framework.


Improving building monitoring using a data preprocessing storage engine based on MySQL


This paper describes a database system designed to historically store and process various building data streams. Storage rules minimize database load while a number of data preprocessing functions enable effective data analysis. Various performance optimizations minimize required computer resources. A real world implementation demonstrates the utility of the storage engine in a realistic and practical context. Performance benchmarks are conducted to show the practical limits.


Validation of Simulation Results using Sensor Data to Improve Building Control


In general, current Building Energy Simulation Tools are used for pre-construction design and comparison of designs rather than a full exact varying representation of reality. To provide the best level of detail full CFD analysis for the entire building would be required. However this is currently by far outside the scope of current computing power and labour efforts for a building energy system. Because these simulation tools are designed for comparison of potential designs and because of the difficulty in predicting occupancy behaviour, very often the predicted results do not correlate with the real actual performance when buildings are in operation. This paper describes a methodology being developed to combine building energy simulation results with accurate and real sensor & meter data with the purpose of better understanding the relationship between energy simulation and real building operation for better occupant confort and more efficient operation.


A generative schema for a hierarchically distributed multi-domain and multi-zonal building systems control architecture


Design methods for buildings’ systems control have not kept pace with the integration requirements of increasingly complex technologies for heating, cooling, ventilation, and lighting of buildings. Decisions regarding the environmental control systems’ type and devices, the number and extent of control zones, as well as the number and position of sensors seldom follow a structured approach with traceable reasoning. Moreover, decision processes in one domain (e.g. thermal control systems) are rarely coordinated at a deep level with other domains (e.g. visual control systems). Such lack of structure and integration is likely to cause inefficiencies in the design and operation of buildings and their systems. In this context, the present contribution discusses a generative schema for representation of buildings’ systems control architecture. The schema is inclusive vis-àvis multiple control domains and associated control zones. Moreover, it allows for an integrated and structured distribution of systems’ control logic.
