Characteristic values of natural ventilation and air conditioning.


The investigation is part of the NATVENT (trade mark) project, a concerted action of nine institutions of seven European countries under the Joule-3 program. It aims to open the barriers that block the use of natural ventilation systems in office buildings in cold and temperate climate zones. The choice to apply natural ventilation in office buildings is very arbitrary: it depends very much on the personal preference of the architect or is made for budgetary reasons, even sometimes not considered at all. This article proposes a method of comparing natural ventilation with more complicated mechanical ventilation systems based on reliability, comfort, initial and maintenance costs and energy consumption. It shows clearly the strong points (cheap, reliable) and the weak points (limited cooling capacity) of natural ventilation.
