Ventilation for Designing Better Buildings

Mold, Indoor Air Quality, and Your Health

Having a home that is not ventilated well may imply that you’re setting up a veritable breeding space for mold, thus promoting inferior indoor air quality which may in turn effect the health of the household.

Mold is beneficial for outdoor purposes of breaking down organic matter such as dead trees and fallen leaves but increasingly harmful indoors. They reproduce extremely small, almost invisible spores that bloom in moist and warm conditions and float in the air. The best way to control mold growth indoors is by controlling the moisture in the house.

There can be many sources of moisture in your home including holes, cracks, or other indentations that may cause surface runoff and rainwater to leak through walls and roofs. Laundry, cooking, and other daily activities too can lead to moisture in case of inadequate ventilation. Mold growth can also boost due to unvented space heater that cause rise in moisture.

It is not necessary that air quality be affected only when there is mold in your house. If you live in an area above or around a place where there is mold growth, air leakage can cause the deterioration of the air quality of your home. You must also inspect for any duct leakages in case of poor air quality in your house.

There can be a lot of moisture caused by condensation in hidden areas of your home. This, combined with suitable warm temperature may make your home a breeding ground for molds.

Health problems caused by molds

Molds tend to produce irritants or allergens and sometimes even certain toxic elements or mycotoxins. Outdoor molds are not as much a cause of issue as indoor molds since they degrade the air quality within the house. Thus, indoor molds may cause certain health problems such as allergic reactions including:

– Runny or stuffy nose

– Sneezing

– Red irritated eyes

– Skin irritation or rashes

– They may trigger respiratory issues like an asthma attack

Thus, mold growth due to moisture may make your home a less healthy place to live in by polluting your indoor environment.

Improve Indoor Air Quality and Solve Mold Problems with Proper Ventilation

One of the first actions needed to minimize or eliminate mold related problems are to clean any visible mold growth and fix any water leaks or other sources of moisture. Even if you’ve got the mold treatment done, chances are it will grow again if the water issue is not fixed. While getting rid of molds and mold spores entirely may be an almost impossible task, it is entirely possible to stall the mold growth by ensuring that they do not get proper growth conditions in terms of temperature and moisture. You may also get air-sealing work done to minimize the exchange of air in case the air is getting degraded from an external source.

Ventilation is important to fight bad air quality and to treat moldy homes as it is only through proper mechanical ventilation that you can limit the relative humidity of your home and avoid moisture troubles thus inhibiting the growth of molds. Moreover, ventilation also helps with air movement thus lowering the rate of condensation on cold surfaces such as window-sills. A proper ventilation system is thus the key to improving your indoor air quality.
