Natural Ventilation Solutions

Natural ventilation has become an increasingly attractive method for reducing energy use and cost whilst providing acceptable indoor environmental quality and maintaining a healthy, comfortable, and productive indoor climate rather than the more prevailing approach of using air conditioning which in turn fails to reduce carbon emissions.

Natural ventilation is the right choice for anyone concerned with the environmental and financial costs associated with air conditioning.

With an increased awareness of the cost and environmental impacts of energy use, natural ventilation can be used as an alternative to air-conditioning plants, saving 10%-30% of total energy consumption.

With an integrated system utilising the concept of natural, controlled natural ventilation systems, architects can rely on pressure differences to move fresh air through buildings.

It is useful to think of a natural ventilation system as a circuit, with equal consideration given to supply and exhaust. Openings between rooms such as transom windows, louvres, grills, or open plans are techniques to complete the airflow circuit through a building.

Natural ventilation, unlike fan-forced ventilation and air conditioning, uses the natural forces of wind and buoyancy to deliver fresh air into buildings. Fresh air is required in buildings to alleviate odours, to provide oxygen for respiration, and to increase thermal comfort.

At interior air velocities of 160 feet per minute (fpm), the perceived interior temperature can be reduced by as much as 5°F.

In summer, wind is used to supply as much fresh air as possible while in winter, ventilation is normally reduced to levels sufficient to remove excess moisture and pollutants.

Alliance Aircon can create healthy room conditions as pre-condition for physical and mental well being as well as a prevention of structural damage because of moisture through natural ventilation. This form of ventilation will reduce energy consumption and operating expenses.
