Ventilation Services Home ventilation is key to having an energy efficient and comfortable home. Our team at Greenmark Home Performance knows how to help you keep the air in your home fresh with home ventilation solutions. There are many areas of your home that need to be ventilated including your bathroom, kitchen, basement, and if possible, your whole house.

In order to have an energy-efficient home, you may be required to have a mechanical ventilation system. These systems are designed to help you maintain good air quality in your home. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) have determined that a typical home’s living space should be ventilated at a CFM rate determined by adding 3% of the conditioned floor space to 7.5 times the number of bedrooms plus one. This means that in a compact home, additional ventilating systems may be necessary to get to this rate.

Why Should You Ventilate Your Home

For years homes were not ventilated, and they worked just fine, didn’t they? Why should we ventilate our home when older homes don’t seem to need ventilation?

There are several reasons that ventilation is more important today than it was years ago. Most importantly, houses built 50+ years ago were drafty and usually had poor air sealing. This allowed for fresh air to pretty easily enter through cracks, gaps, and holes in the structure of the building. In addition to this, the building materials uses have changed and modern building materials can cause off-gassing of volatile organic compounds such as formaldehyde, flame retardants, and other chemicals.

Ventilating your home is the first step you can take to ensuring that your home is free of gasses, chemicals, and other harmful pollutants.

This involves the uncontrolled air movement into and out of the cracks and crevices of our home. Typically in the past when homes were being built, these openings were left as-is, but today builders seal all the openings and holes to a home to help make it more energy efficient. When your home is properly sealed, you are going to need to have a ventilating system installed to help make your indoor environment healthy and comfortable.

This technique involves the use of exhaust fans, such as the ones installed in bathrooms. The strategy can also help with improving how well your natural and whole-home ventilation systems work be helping to remove indoor pollutants and moisture. ASHRAE recommends that intermittent or continuous rates for bathrooms of 50 to 20 cubic feet per minute.

This is often the technique used in homes where families worry that natural and spot strategies aren’t enough to provide the proper air quality. Whole-home techniques use one or more fans and duct systems to remove stale air and to supply fresh, healthy air into the living environment. There are several different types of whole-home systems available, including: exhaust, supply, balanced, and energy recovery units.
