Natural ventilation and shading: the key to healthy and comfortable indoor climate

Speaking is Paul Renson, CEO of the company of the same name, which is fully committed to healthy living with its innovative solutions. For the CEO, the challenge of the future is to bring people closer to nature again. Renson does exactly that by cleverly deploying the natural elements (sun, light, air) in the building process.

Everyone today wants large windows with plenty of natural daylight indoors, and all the while global warming is causing more and more hot days and heat waves every year. Therefore, keeping indoor temperatures under control is an absolute priority to avoid overheating. An energy-guzzling air conditioner is not the only solution. On the contrary: it even contributes to increasing CO2 emissions. Renson commits itself in this area with a smart total solution for passive and sustainable 'cooling' thanks to the combination of exterior sun protection and 'night cooling'. Managing daylight with dynamic and wind-resistant fabric awnings such as Renson's Fixscreen is a first step in the right direction. It is also the most efficient solution for preventing rapid heating indoors, as outdoor blinds block the sun's rays before they even have a chance to reach the glass. Larger flows of fresher outside air - via window grilles or folding shutters, permanently incorporated into the frame of the windows - can in turn serve to cool things down inside at night.

Healthy learning and working

A healthy indoor climate is essential not only at home but also in the office. For Gare Maritime at the Brussels Tour & Taxis site, Renson developed custom-made windproof fabric awnings for the extensive window sections. These naturally prevent overheating in the offices.

It has also been proven of schools that indoor air quality affects the ability to concentrate and thus the performance of students. They also know this at Sancta Maria elementary school in Gentbrugge, where thanks to Renson's Invisivent window vents and Healthconnectors - which continuously monitor CO₂-level and control the exhaust flow rate of polluted indoor air accordingly - classrooms are always assured of fresh air.
