Natural Ventilation and Forced Warm Air Ventilation in Offices

Abstract

The paper is oriented on the natural ventilation and forced warm air ventilation systems in offices. The basic element of natural ventilation system in office building is double skin facade. The natural air circulation is undertaken by the right shaping of vertical shafts for exhaust air. Furthermore, the intelligent double skin facade in transitional period contributes to the heating and in summer to natural cooling of offices. Therefore, the forced warm air ventilation, which is provides heating of offices, can operate in saving mode and can be supplemented by radiant floor heating. By the effort to approach to zero energy balance, it is important to undertake thermal comfort. Therefore, I did experimental laboratory measurements for forced warm air ventilation and I also did it because of comparison for radiant floor heating. In this paper, I will present scientific analysis and the outputs from my own measurements. In the conclusion of this paper on the basis of outputs of experimental measurements I will define the principles for designing forced warm air ventilation and radiant floor heating in offices.
