Project Summary


Research in URBVNET project aims to provide methodologies and accompanying software tools to assesss the potential and feasibility of natural ventilation, and to design optimal facades for natural ventilation in urban environment, accessible to architects, designers and decision makers.

The methodolgy and the toolsare tested in three stages by the developers, research estiblishments that play the role of end-users and project integrator. The results will be sisseminated in 25 European countries by using the network of national professional associations, having a potntial target population of about 100,000 specialists.

The philosophy of URBVENT is to use distributed skills and knowledge in order to obtain low cost and energy efficient solutions as alternative to relatively unskilled installing of expensive, energy consuming manufactured systems.

Description of the work

The fundamental of URBVENT work-plan is the cooperation between university research laboratories and research centrers, which represent industrial end-users, to produce knowledge accessible to the European specialists.

The design of natural ventilation needs the pressure and temperature distribution around the building and the airflow characteristic of the building. In order to provide this information, the project is divided in four workpackages (WP):

  1. Soft Computing of Natural Ventilation Potential
  2. Optimal Openings Design
  3. Engineering Validation
  4. Synthesis
