Some of the most common problems in our homes can lead to health issues, loss of comfort, and wasted energy which in turn leads to money lost.
For every event there is a cause and effect in other words when one event causes another to happen. The cause is WHY it happens. The effect is WHAT happens. In rare circumstances are the full effects felt immediately but rather develop over time. For example the bathroom vent becomes disconnected and now venting directly into our attic. We don't develop asthma that day. But as moisture is introduced into the attic it begins the cycle of mold growth and as the mold grows it will produce more and more spores to get airborne which in time will lead to health problems like asthma. I believe that every consequence is the result of the "Cascade Effect". "A Cascade Effect is an inevitable and sometimes unforeseen chain of events due to an act effecting a system." One of the first things BPI home performance experts are taught is to think of the home as a system. If we can break the chain in these events we can prevent the negative consequences. We can do that through testing, analyzing, and action (maintenance, repair and preventative maintenance ).
Check out Grandma's House this demonstrates these effects and consequences.
