Urbvent – Natural ventilation in cities

Natural ventilation in urban areas – assessment of potential and optimal façade design

The URBVENT project aimed to provide a methodology to assess the potential and feasibility of, and to design optimal façades for natural ventilation in an urban environment, accessible to architects, designers and decision makers. The methodology and the tools were tested in three stages by the developers, end-users and project integrator.

Project duration: 2001-2003

The project consisted of four workpackages (WP):

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

The main contribution of the LESO-PB addressed WP 1. A model was developed to predict the natural ventilation potential of buildings in urban climates. This model is easy to use, but nevertheless takes account of all the parameters influencing natural ventilation, including those for which only qualitative information is available. It is based on qualitative multicriteria analysis.
