Doors and windows are the common parts of any air-conditioned area through which air leakage takes place. In any temperature-controlled zone, leakage of air means fast leakage of energy (applicable in both ways/directions). So, if leakage continues for a prolonged period of time, the energy consumption increases proportionally.

 Thus, air leakage is an incident that actuates mounting of the cost of operation, and obviously, once noticed, it needs to be controlled as soon as possible. There are cases where even more than 25 to 30% reductions of the energy bills have been achieved just by air leakage control.

 When we delve into the reasons behind air leakage, we often find some very common yet highly neglected causes. For example, there may be cracks, gaps and holes in the enclosing walls. However, doors and windows, more specifically doors are often found to be the main leakage points. In air-conditioned spaces windows are often kept nicely sealed and secured. But doors are repeatedly opened and closed, also there are vibrations in frames.

 As normally, the air pressure is higher inside, the chance of outward air leakage is more in any enclosed system. Contextually, a report from the US Dept of Energy highlights, “One of the most common air conditioning problems is improper operation. If your air conditioner is on, be sure to close your home’s windows and outside doors. For room air conditioners, isolate the room or a group of connected rooms as much as possible from the rest of your home.”

 So, when we look at it from the comfort angle, we find, a well-insulated home makes its occupants more comfortable. The comfort is physical as well as economical. Now, the question is how to find out whether there is leakage in your enclosed space. The first step is to do a physical inspection. Check both the interior as well as the exterior part thoroughly. Old caulkings around the door or windows are often found to be damaged. Identification of air-leak-channels and insulation defects can easily be done with the thermographic imaging technique.
