Moisture in Buildings Studies
Among various climate related causes that affect buildings is moisture. Not only that, studies that come back to middle 90s shown that 75–80% of all the problems with building envelopes are due to a certain extent to moisture. Later on in 2002, a finding of a cross-sectional analyses done in Finland by Haverinen is really surprising : 38% of detached houses and 25% of apartments were experiencing notable or important moisture issues. In the same year in Sweden (Wessén, Honkanen, Mälarstig, 2002), a study of more than 400 buildings found that 65% of the buildings were having moisture problems. Moisture had led to the growth of microbes in these buildings. These studies have without a doubt risen the awareness of many scientists and should therefore do the same to everyone of us.
Solutions to Indoor Humidification
Today, many people go right to buy a device to cope with humidification problems and doesn’t look for natural dehumidification means. These devices are called dehumidifiers and which are designed to remove indoor moisture by dehumidifying air of the room. This is done by condensing water which is in vapor form, and collecting it in a tank in a first step. The second step is to get air back to the room in its same temperature level. Frigidaire dehumidifiers are one of the most rated units of this category and some models could dehumidify up to 70 pints of water per day.
Examples of Most Common Moisture-related Problems
While some of the examples listed below are very obvious, many people are not aware of the danger of some simple dysfunctions in our homes and which are directly connected to moisture.
- Water on the roof or walls coming from rain which often results in mold growth
- Plumbing is sometime not properly designed or installed which results in spills and leaks.
- When fixing a plumbing problem, it may have been nicely installed but after maintenance, some plumbing problems may persist or arise.
- When weather is warm and humid, you may experience an infiltration of warm or moist from outside entering through crack in the enclosure.
- The opposite effect could happen as warm or moist could get outside your home through holes in the enclosure and which can result in condensation in your house´s walls or ceiling.
