Heat, Humidity, and Healthier Homes

Many areas of the U.S. have been experiencing extreme heat and drought in recent weeks. These trying conditions can lead to comfort issues, distress, and even acute health concerns. In some areas of the country, especially in moist climate zones, the summer heat can be further exacerbated by excessive moisture and humidity. This can lead to similar comfort and health concerns, while also increasing the potential for building durability and mold issues. The Indoor airPLUS Construction Specifications include regionally-specific requirements to help address excessive moisture and humidity with the design of the home’s mechanical systems.

High levels of humidity can cause the indoor environment to feel sticky and uncomfortable.    .In extreme cases, excessive humidity and moisture can lead to severe mold damage.Potential health effects and symptoms associated with mold exposure include allergic reactions, asthma, and other respiratory complaints. Bathrooms and showers are a common source of moisture and high humidity, which can lead to mold growth.Indoor airPLUS Humidity and Moisture Control

Indoor airPLUS labeled homes provide comprehensive indoor air quality protections.

Indoor airPLUS labeled homes are designed with moisture control in mind. Moisture can be carefully controlled, both mechanically and by the tightness of the home. Ventilation fans in bathrooms and kitchens are an important feature to control moisture and maintain a healthier and more comfortable level of humidity.

Additionally, the Indoor airPLUS Construction Specifications require dehumidification measures in warm, moist climates to help ensure homes are not only comfortable and efficient, but also protected against excess moisture or mold growth.
