International professional organisations launched a new initiative to raise awareness on ventilation

REHVA is one of the initiators of an international awareness campaign to promote the critical role of better building ventilation in supporting #health, #well-being, and #productivity. The first annual World Ventil8 Day (#WorldVentil8Day) is today,November 8, 2022 with parallel awareness raising actions around the world.

REHVA President Catalin Lungu said on the occasion of WorldVentil8Day: “I strongly welcome this initiative, because it contributes to raise general awareness about the importance of adequate ventilation to ensure healthy indoor environment. REHVA has been advocating for indoor air and climate quality ever since its foundation, in 1963. Promoting knowledge and high-quality engineering practice in the HVAC sector to keep healthy indoor environment is in the DNA of REHVA. We pursue this mission with our member associations, supporter companies and partners in Europe and across the world. I hope more and more organizations will join “WorldVentil8Day” in the future.”

REHVA joined BESA (the Building Engineering Services Association), CIBSE (the Chartered Institution of Building Services Engineers), IMechE (Institution of Mechanical Engineers) and FETA (the Federation of Environmental Trade Associations) toward the goal of improving ventilation for a healthier world.
