Summer comfort in educational establishments: ceiling fans to the rescue?
With hot spells sometimes starting in May and ending in September, educational establishments are increasingly confronted with thermal discomfort that degrades learning conditions. What solutions are becoming possible to improve the situation in existing buildings?
Ceiling fans: what are the layout rules?
Ceiling fan layout: saving means and resources. Why is a precise fit between different air curtains so important?
Two imperatives need to be reconciled: the budgetary imperative and the thermal comfort imperative. Too few fans in a given space, and comfort becomes insufficient. Too many fans in the same space, and the budget slips…
Ceiling fan acoustics: focus on the NF Habitat HQE label
The arrival of the ceiling fan in RE2020 has prompted several home builders to ask us about the noise levels to be achieved under the label.
Ceiling fans in new multi-family housing: how do they fit in with environmental labels?
At the heart of people’s lives, the construction industry is keen to promote the most exemplary projects. In the 1990s, labels for energy performance (BBC Effinergie, Passivhaus, Energiespong), low-carbon performance (Biosourcé, BBCA), biodiversity (Lucie, Biodivercity)… and environmental performance were introduced.

Minimum height under blades: what are the safety rules?
Ceiling fans are high-speed devices. Take the case of a fan with standard blades. Its rotation speed often exceeds 200 rpm. That’s 50 km/h at the tip of the blades! Without wishing to caricature the situation, a head-on collision with a car at 50 km/h can be a bad time to spend. To take this into account, let’s look at the safety rules that have been laid down to limit the risk of injury.
Air movers and air conditioning: a marriage of convenience?
A little thermal comfort is welcome. The question of coupling air movers and air conditioning is on the agenda. Of course, there is a real physical difference between these systems. In energy terms, air mixing has little impact, whereas air conditioning has a high consumption. Let’s take a look at this combination of air conditioning and ventilation in the warm season.

For air movers, the RE2020, the new environmental regulation for new buildings, is a great step forward. Ceiling fans are now recognised as strong pillars of summer comfort. However, the regulation misses important benefits of air movers in relation to thermal comfort and energy consumption.
What are these beneficial impacts that have yet to be integrated into the RE2020?
