Homeowners will be thankful to know that there are a variety of ways to reduce a home’s cooling costs. Some of these methods are entirely natural, incredibly clever, and definitely worth looking into.
Turbine ventilators are commonly suggested to homeowners by Tapa emergency HVAC service professionals. These are the small whirling globs that are commonly seen on the rooftops of older buildings. These natural ventilation solutions are making a strong comeback, and for good reason. These ventilators use air motion at the top of the home to circulate the air of a home. Although they initially seem to act much like a fan, they operate entirely based on the force of the breeze running through them. The breeze catches the turbine’s fins, causing it to spin. It them pulls the air upward and allows it to run through its openings. Cool air is then made to enter the home at a low level, effectively taking the place of used, stale interior air.
Wind catchers are great natural home ventilation solutions for areas that would commonly experience breezes were it not for the landforms, buildings, or vegetation that block those breezers. Wind catchers are built to carry those breezes directly into the home. These are alternatively known as wind scoops, and have been used traditionally in the MIddle East (a high temperature area replete with buildings that tend to be packed closely together, thus blocking the passage of breezes) for generations. Essentially, a wind catcher rises from the home like a tower, setting up camp in the space of air above the surrounding rooflines. It’s installed to face the direction that prevailing winds come from. The catcher picks the breeze up from the top of the home and transfers it into the home’s interior. Almost immediately, the air within a home becomes cooler and fresher, and the home is permeated with a nice breeze.
The Chimney Effect
This is a particularly sound practice for homes in areas that rarely experience a breeze. The chimney effect is centered on the rising of warm air. As the air is heated, it then expands and becomes lighter until it eventually rises. If the rising warm air is made to escape in a high structure, cooler, heavier air will take its place, entering through an opening lower in the structure. The vertical distance between the inlet and the outlets, the difference in air temperature from the top to the bottom of the chimney, and the size of the openings affect the rate of air movement. As each of these features increase, so does the speed of the air movement. This natural ventilation strategy is efficient since the prevailing breezes don’t require any direction in particular; essentially, they organize themselves.
