Approximately 300 low energy houses have been built in the Republic of Ireland by the multi-national CRH Plc and South Dublin County Council as part of a co-ordinated European Commission-supported demonstration project, RE-Start (Renewable Energies Strategies and Technology Applications for Regenerating Towns).
Insufficient concern about energy efficiency during the design and/or the operation of a building is the main reason for the high energy consumption of existing buildings. The knowledge of facility managers about the real energy consumption is often poor, regular documentation or analysis of consumption data are not existing. Enerkenn therefore intents to develop a procedure to record and evaluate relevant energy data and to find out energy saving potentials with environmentally conscious and economically reasonable accuracy.
The central subject of this Workshop was the challenge offered by energy performance regulations to find adequate solutions for the integration of innovative technologies in such regulations.
The thesis deals with human perception of the environment, sick building symptoims and the performance of office work in the indoor environment. Single and combined effects of temperature, heat stress, noise and air quality have been studied in three experiments.
This guide describes the principles of demand controlled ventilation, gives information about the type of buildings where it can be used, and underlines the benefits of such systems with regard to energy consumption. It also shows how to design a demand controlled ventilation system according to the type of control. It explains the importance of choosing the right type of sensor and the correct way to posiiton it in the room.
This information dossier describes the general principles of natural ventilation, the calculation of air flows and the strategies for building cooling. It presents case studies of six office buildings, with the lessons learned.
The document consists in the Proceedings of the 2000 AIVC conference, which took place in The Hague (The Netherlands) in September 2000. It contains 61 articles corresponding to the speeches given during the Conference, and a summary of the discussions in the different sessions.
This paper deals with a computer simulation of airflow and indoor environment in livestock buildings. Simulation results have been analysed and visualized with a Virtual reality visualization . The definition of virtual reality is given first , then the presentation of the 3 Virtual reality systems possibly used for the visualization, and finally a simulation tool.
5 cases were selected to demonstrate the different simulation and visualisation possibilities for people form the industry.
In so far as a CFD analysis is becoming more and more complex. The presentation of the results must be adapted according to the audience. This paper gives first different methods of analysis and an overview of different levels for the presentation of CFD results. Examples of complex flow visualizations illustrate that paper.
This paper deals with the effect of discharging the air from a diffuser elevated above the floor. The temperatures have been measured and the airflow patterns visualised close to a diffuser for displacement ventilation, results from the whole-field method (using infrared thermography) were images of different colours representing different temperatures of the air close to the diffuser.. The aim of the measurements was to see how the elevations of the diffuser above floor level and the thermal jet length of the supply could affect the near zone.
