Study of a particular stack performance in a building.

Abstract

Natural ventilation has gained prominence in

recent times as a method of ventilating buildings. The two

fundamental principles of natural ventilation are stack effect

and wind driven ventilation. This paper describes a particular

stack performance realized in a building (school) at real scale

by computation of the wind induced ventilation and a

comparison of the stack performance (airflow rate extracted and

wind speed) respect to other systems (wind catcher, wind jetter

and wind turbine) are also showed.

The realization of the

system, actually working, shows the synergy between a plant

design and installation using traditional energy sources with

innovative engineering techniques providing for the use of

integrative energy. In this case, the wind action plays an

important role for the conditioning of the school, integrating

and giving a significant energetic contribution to the air cooling

system. The school building (a nursery) has been built in

Modena and is actually working
