The focus of project Web has been the development of wind enhancement and integration techniques which improve the annual energy yield per installation by concentrating the low to moderate wind speeds (2-5 m/s).
The main aim of the Tip-Vent project was to provide a contribution o the creation of improved boundary conditions for the application of mechanical ventilation systems with good levels of performance. The project has led to a better understanding of the true performance of ventilation systems, why they perform as they do and what improvements are achievable.
The Solvent window was developed to improve visual and thermal comfort in sunny conditions. The glazing system realizes the conversion of short wave solar radiation to convective heat and long wave radiation.
The objective of PV-cooling project was to develop low electricity consumption cooling systems for dwellings and office building, powered through photovoltaic (PV) electricity. Two systems have been developed, one using PV and evaporative air-cooling, the other using PV and ground cooling through buried pipes.
The key objective of Precis was to evaluate the potential of renewable energies, including natural ventilation, in cities by exploring the relationships between urban form and energy/environmental performance.
The Airinstruct project objective was to understand the thermal performance of ventilated building components, namely ventilated roof, ventilated wall, solar roof and dynamic insulation.
This technical note from AIVC aims to provide information on residential ventilation systems and how these can be applied to meet the conflicting needs for fresh air and minimised energy consumption.
The REinforced EXhaust System (REEXS) is a local ventilation principle for industrial ventilation with improved efficiency for capturing contaminants released by working processes .This paper discusses the validation of a 3D CFD model for the determination of the capture efficiency of standard local exhaust ventilation systems.That study has shown good results in 3 ways :- Properly designed REEXS hoods , compared to conventional exhaust devices have a significant increase capture efficiency.- CFD is an excellent tool to predict different local ventilation strategies in a quantitative way.
This paper presents the results of the performance of a wall-mounted natural ventilation convector under real winter weather conditions. The monitoring results were used as boundary conditions for CFD simulation to investigate the air movement in the test room. The results proved that the convector contributed greatly to the improvement of the indoor air quality.
This paper aims at developing and implementing a fuzzy controller for naturally ventilated building.The first objective of this research was to develop and then validate a rule based controller which can vary the resistance of ventilation opening in order to maximise comfort conditions.
