This is extremely important in order to have an energy efficient St. Louis home. At Greenmark Home Performance, we can provide you with effective air sealing techniques which can help to prevent air leaks. Properly ventilating a home can also control moisture, which is often the cause of the development of dangerous mold and structural damage to your building.
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.

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.
The professionals on our team will help you to determine what type of system and strategy will work best based on your home's unique needs.
