Limiting Abnormal Mold Growth in Buildings
Abstract
Studies show that mold, a fuzzy cob-web-like
growth produced primarily on organic matter, is all
around us. Molds typically begin their lives as
dormant, airborne spores, but when they come into
contact with moisture, a food source, and the right
temperature range, they grow into living organisms
which collectively are called colonies. They are a
basic component of the natural ecosystem. Some
molds, such as penicillin and yeast, are good, while
others such as ringworm and athlete's foot, are not.
Unfortunately, we are learning from studies of
contemporary buildings that abnormal amounts of
certain molds inside our buildings can adversely
affect the health of humans and animals.
The same conditions that support mold growth
also support fungal decay in wood, or rusting and
corrosion of metals. Abnormal mold or fungal
growth, then, can create major problems for building
owners. Moisture is the key factor that building
designers and owners can manage in order to limit
mold growth. This paper introduces some of the types
of molds that are found in buildings, the physical
parameters of growth, what the suspected effects are
on humans and animals, and ways to limit the
moisture they must have to grow. The paper
concludes with suggestions for designing,
constructing and maintaining buildings to minimize
the potential for mold growth.
