What is the Stack Effect?
The Stack Effect, also referred to as the chimney effect, is the natural heat transfer that occurs throughout buildings. If you have a multi-story home, this phenomenon is happening all around you and your loved ones daily.
Air enters your home through crawl spaces or basements, travels up through your floors and walls, and exits through your attic. Without proper insulation, this air loss and intake cycle throughout your home will have your HVAC system working harder than ever. The Stack Effect results in excessive energy bills and inconsistent temperatures if not properly managed.
How the Stack Effect Works
The Stack Effect is controlled by a building's height and the difference between inside and outside temperatures. The greater the difference between the two, and the taller the building, the greater the pressure created. Warm air has a lower density than cool air, causing it to rise to the upper levels of a building. This pressure causes cooler air to be pushed to the bottom of the home. While warm air rising may seem beneficial during long winter nights, it won't stay put once it gets to your bedroom ceiling. Most homes have many holes, gaps, or leaks for warm air to escape. To make matters worse, any warm air that leaks from the top of your home is replaced by cool air sucked in from the bottom. During the warmer months, the Stack Effect is reversed. Cool air tends to fall and get forced out through the bottom of your home, allowing hot air to enter from the top. If this cycle is unchecked, it will inevitably strain your air conditioner and furnace.
The Stack Effect Can Also Cause Moisture Damage
As outside air creeps into your home, so does moisture. As more moisture circulates in your home, your chances of mold and mildew growth increase. This is only one of many concerns that arise if your crawlspace has too much moisture.
How to Reduce the Stack Effect in Your Home
The best way to reduce the Stack Effect is to seal any air gaps in your home. This can be accomplished by having your home professionally insulated. Not only will this make your home more comfortable, but it also increases your home's energy efficiency, reduces your carbon footprint, and helps lower monthly utility bills.
