ASHRAE

High performance homes provide comfort, durability, indoor air quality, and lower energy use. These are major benefits of tight construction or a tightly sealed home. However, you can only tighten a home if you have a means of ventilating any indoor contaminants.

Think about the amount of time people spend indoors. Studies show we spend up to 90% of our time in doors. This could be in shopping malls, restaurants, grocery stores, at work and at home. People spend the majority of their time inside in some capacity. 

Indoor air quality is so important to our health and well being. Ventilation is an important component to removing contaminants and pollutants and achieving acceptable indoor air quality.  

ASHRAE provides the ventilation standards and best practices using whole house ventilation and/or spot ventilation to ensure that any pollutants and contaminants are being diluted and exhausted outside.
