The Importance of Natural Ventilation and Daylighting

Let Warm Air Out and Sunlight In.

Studies show that we work better in environments with plenty of sunlight and fresh air. The importance of natural ventilation & daylighting in the U.S. is still under emphasized. Buildings all over the world have seen its benefits in schools, offices, and industrial plants, but the U.S. is lagging behind. From students to office staff, to factory workers; everyone works more efficiently in properly lit, properly ventilated spaces. That is why proper lighting and ventilation that brings in fresh air are the best types of natural ventilation in buildings.

importance of natural ventilationWith the advent of the centralized air conditioners and HVAC systems, the air inside of many commercial office buildings is almost entirely recycled. These units keep buildings cool and move air deep into the middle of buildings. This is pretty effective at keeping workers cool but there is usually a trade-off in air quality. HVAC systems can lead to bacteria build-up and the circulation of dirty air. These same interior locations are often lit with harsh fluorescent light, which in addition to helping these same bacteria grow, can also have a negative effect on worker morale.

While factories and large industrial spaces rarely use the same air conditioning as office buildings, they too experience ventilation problems. Production facility often have hot, humid, and contaminated air. Large facilities are difficult or impractical to air condition, so instead the warm temperatures are just tolerated. As these buildings house large machinery, this can lead to a buildup of fumes and harmful byproducts in the air.

Implementing New Technology, Adopting Old Technology

Buildings needed openings to ensure the air would move through the building and keep it cool. As people have discover HVAC ventilation problems, like those mentioned above, building owners revisit the technology of the past. That is why more and more building owners choose natural ventilators instead.

A natural ventilator is an effective way to help bring fresh air and natural light into a building. By placing vents to let the hot air out at the ceiling level and intake openings on side walls at the floor level, air will move throughout the interior space. This method uses the laws of thermodynamics to efficiently ventilate and remove stale, hot air while bringing in fresh cool air. This constant stream of air prevents the recycled air problems of office buildings as well as the humid, stuffy air problems found in factories.

Of course, natural ventilation also provides natural day lighting. Roof vents must be open to letting air out so, in turn, they let light in. Natural ventilators used in office buildings are often in more wide open areas like a lobby or a hall. This lets workers come into contact with the sunlight more often, but not on a regular basis.

In factories, however, where the workers are in a large open area, they can be directly under the natural ventilators. Very large facilities can get a lot of light through a natural ventilator.

With no moving parts, a natural ventilator is self-sustaining, requires no maintenance and uses no electric. At Moffitt Corporation, we have more than 50 years of experience in designing, manufacturing, and installing natural ventilation and natural daylighting systems. At the end of the day, we must all recognize the importance of natural ventilation and daylighting systems. Furthermore, we must implement them when possible.
