If you want to build a house for your family, you have to consider the home ventilation system as well. Home ventilation is very beneficial for airtight home. It can also help you control the moisture of your home for providing you a healthy, cozy, and energy-efficient home.
What is the Purpose of Ventilation?
Ventilation is very helpful for you to have an efficient exchange of indoor air with outdoor air. It is able to minimize the indoor pollutants, odors, and also moisture. Poor home ventilation can hold some contaminants such as volatile organic compounds, formaldehyde, and also radon. Moreover, high moisture level in your home is also potential to increase the level of humidity which then can lead to the growth of the mold and also structural damage to your home.
In order to have adequate ventilation, you have to ventilate your home at rate of 0.35 air changes in one hour. It is the same as 15 cubic feet for each person per minute.
The Standards of Ventilation
Good ventilation should be able to accommodate all the indoor air quality. The American Society of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE) claims that the standard for good ventilations at rate of 15 cubic feet per minute (cfm) for one person. It means that if your family has 4 people, your ventilation should be at the rate of 60 cubic per minute. To determine the air flow in cfm, you can divide the floor area by 20 in square feet. It is for controlled ventilation, not spot ventilation.
Basic Functions
Home ventilation basically has some basic functions. It is very beneficial for expelling carbon dioxide, stale air containing water vapor, airborne chemicals, and some other pollutants. It can also draw in the outside air which may contain less water vapor and fewer pollutants. Moreover, it is also able to distribute the air throughout the house as well as to automatically control the system operation.
There are two basic elements of ventilation system you can consider. The first is the fan. It can draw the stale air from your home, mostly in the kitchen, utility, and bathrooms. The second is the makeup air supply which can deliver the air around the house with a single supply point for picking up the points. By setting the pickup along with supply points, you allow the outside air to travel to the entire house.
