Humidity Control in Green Building
Humidity in a Green Home
A comfortablehome in the North Texas area is certainly governed by temperature. But humidityplays a large role in comfort, particularly during the summer.
Humidity is the amount of water vapor in the air. It is measured in three ways: absolute humidity, relative humidity, and specific humidity. Seeglossary
Humidity is increased or decreased by severalmechanisms:
1. Air pressure differences cause air to move from high to low pressure.Moving air can either bring water vapor with it OR take water vapor from thehome.
2. Humidity comes from many indoor activities such things as cooking, washing dishes,bathing, and doing laundry. Even human bodies increase the humidity in a home.
3. Drafts can also affect the amount of humiditypresent so humidity problems are fairly common in older or less energy-efficienthomes.
If the amount of water vapor in the air is heldconstant:
1. When you reduce the temperature, the relative humidity goes up.
2. When you increase the temperature, the relative humidity goes down.
Humans are very sensitive to humidity, as the skin relies on the air to get rid of moisture.The ideal humidity levelfor homes is 45%.
An indoor humidity level of less than 30% istoo dry.
You will know your home’s humidity is too low if staticelectricity is shocking you. Skin irritation and respiratory problems are othersigns of low humidity.
Low humidity dries out the noses andthroats of the home’s residents. It causes scratchydry throat, increased allergy symptoms, more frequent colds/infections, and evencracked fingers.
It also affects the wood in the home, whichshrinks, often damaging trim, hardwood flooring, and even wood furniture. Sheetrock and paneling may crack from low humidity.
A home’s heating systemwill lower the humidity.
However, the reverse istrue with a more energy-efficient home and a tighter envelope.
The lack of airexchange coupled with humans and their activities can cause high indoorhumidity.
