Natural Cooling / Ventilation
Nowadays, airtight construction and good insulation are two key concepts that are becoming increasingly important in the construction industry, reducing unwanted energy losses as much as possible. However, this also means that the demand for heat decreases, while the need to cool a building increases. During the warmer (summer) months, the indoor temperature can soar. Not only due to excessive direct solar gains, but also through internal heat gains (lighting, electrical and thermal equipment or simply the presence of a large number of people in one room.) Summer comfort is therefore increasingly being included in a building’s design requirements.
With its wide range of (controlled) wall and window grilles or continuous louvre systems, Duco offers an excellent way of controlling the indoor climate in a natural, efficient and energy-saving way. Without artificial interventions such as air conditioning. This is because by using large volume flows of outside air (intensive ventilation), a building can be perfectly cooled via ventilative cooling (free cooling), provided one or two guidelines are followed:
A – Always use ventilative cooling in combination with good exterior sun protection
B – When designing the building, bear in mind the presence of sufficient thermal mass in the building to store the outside air.
C – Use the correct pressure difference for dimensioning
We would like to highlight two products, which are perfectly usable throughout the ventilative cooling strategy :
