Principles

Energy Comfort Environment

Natural ventilation is governed by the laws of physics: it arises from differences in pressure due to wind and variations in temperature and humidity, induced for example by heat sources, human activity and solar radiation. These differences, which cause air masses displacements, if properly interpreted and exploited, lead to significant improvements in the internal microclimate of buildings.
Natural ventilation systems are integrated into the building organism allowing a significant energy saving and an important improvement in comfort.
Improved air quality in buildings has immediate positive effects on health, productivity and well-being.
Continuous air exchange removes unwanted volatile substances and guarantees a suitable level of oxygen.
Living and working in a naturally ventilated environment increases the perception of freedom: people benefit from the possibility of varying the microclimatic conditions of the place in which they operate.
An accurate design of natural ventilation leads to optimal working conditions with low investments and zero operating costs.
Climate change, the consumption of fossil fuels, the increase in energy costs: these are important issues for the future of the planet. Natural ventilation systems are a tangible alternative solution for cooling buildings with zero environmental impact.

How it works

Natural ventilation systems exploit the natural movements of the air induced in particular by the so-called "chimney effect". Additional variable climatic components such as wind or geographical exposure improve the performance of the system, increasing the air flux that pass through the building.
There are many advantages:
- no energy consumption
- no maintenance
- they work without any human intervention
- the air flow rate depends on the heat to be removed: more heat implies a greater volume of extracted air.
Natural ventilation allows you to take advantage of the building's thermal inertia, the so-called "thermal mass". During the night, the system uses lower temperatures to dissipate, not only the heat present in the volume of the building, but also that one accumulated by the structure of the building during the hottest hours of the day. In this way, in the morning the internal environment will be already cooled with a substantial advantage that can be spent during the day: when the heat generated by the activities, or transmitted by the environment, will begin to accumulate inside the building.
The economic advantage that can be obtained is significant since natural ventilation acts as a cooling system that is always available and free.
