Humidity in New Homes – Understanding and Controlling it

Education Humidity in New Homes – Understanding and Controlling it

Today’s energy-efficient homes are built tightly to seal out cold in Winter and keep in the cool in Summer. Even code-built homes are tighter than they have been historically. Thanks to this, it’s possible a new home may be damaged by lack of ventilation or by excess moisture.

Through  laundry, bathing, washing dishes and just breathing, as many as 20l of moisture may be added to the indoor environment on a given day.

Most builders have likely received one of those dreaded phone calls: “Why do my windows have water and mold on them?” or, “My hardwoods are cracking and I don’t know why!” or even the panicked “My basement is leaking!”

Humidity control is a significant issue in new homes, especially as we push the energy performance of homes closer to Net Zero Energy. From swelling of engineered hardwood, musty smelling basements and window condensation to short cycling air conditioning units; understanding humidity and specifically relative humidity is important to all homebuilders, their HVAC partners and happy homeowners.
