Why is moisture control important in achieving a good HERS rating?

Moisture control is crucial in achieving a good HERS rating because it directly impacts the health, durability, and energy efficiency of a home. By managing moisture levels effectively, you help prevent the growth of mold and mildew, which can lead to severe health issues for occupants as well as significant structural damage to the building. When moisture penetrates building materials, it can weaken them and create an environment conducive to pests, further complicating the home’s integrity.

Additionally, moisture control contributes to the overall thermal performance of a home. Excess moisture can lead to higher energy consumption as heating and cooling systems work harder to maintain desired indoor conditions. Thus, proper moisture management is integral to the overall sustainability of a building, aiding in both its comfort and energy efficiency, which are key components in determining HERS ratings.
