Natural Roof Ventilation Systems

Natural ventilation is the intentional passive flow of outdoor air into a building through planned openings such as louvers doors and windows.

Airocle are the masters of natural ventilation learn about our industry leading 360º airflow analysis optimise your ventilation systems for clean safe air and a comfortable environment. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. Cool air in hot air out attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents. In the french model home maison air et lumière mal the indoor air quality was evaluated with special focus on the effects of the natural ventilation system during summer.

See the benefits of attic ventilation a new roof is more than just shingles. This adjustable solar panel bracket system maximizes the sun exposure on the solar panel no matter if the unit is installed on a flat standard pitch or steep roof. Fan noise often associated with mechanical systems is virtually eliminated the simple but effective design of the system provides fresh air during the daytime as well as night time cooling. Instead it relies entirely on passive physical phenomena such as wind pressure or the stack effect.

Dogtrot houses are designed to maximise natural ventilation. Intake vents located at the lowest part of the roof under. A natural system works best in a building with no ceiling but having small openings at the eaves and ridge peak of the roof and having large sidewall openings figure 2. Example from mh 2020.

While hardly anybody agrees on the best roof ventilation system everybody agrees some roof vents do hardly any good at all. Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. The natural light solar attic fan is designed with an exclusive adjustable bracket allowing the solar panel to be positioned at various angles for optimal solar exposure. Take for example ridge vents.

Natural ventilation does not require mechanical systems to move outdoor air. The majority of roofing experts agree that ridge vents are the most effective and cost effective roof vents available. Natural ventilation in a gable roof building occurs primarily because of the wind blowing over the ridge and to a lesser degree because of the temperature.
