2. Basement waterproofing - Wikipedia

   en.wikipedia.org/wiki/Basement_waterproofing

   The main purpose of external weeping tile is preventing water from getting into a basement. However, these pipes can become clogged or damaged, which causes excess water to put pressure on internal walls and basement floors. Water build up inside window wells, after heavy rain or snow, can lead to leaks through basement window seams.

3. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements that have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at ...

4. Waterproofing - Wikipedia

   en.wikipedia.org/wiki/Waterproofing

   Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.

5. Building envelope - Wikipedia

   en.wikipedia.org/wiki/Building_envelope

   Types of wall systems with regard to water penetration are barrier, drainage and surface-sealed walls. [5] Barrier walls are designed to allow water to be absorbed but not penetrate the wall, and include concrete and some masonry walls. Drainage walls allow water that leaks into the wall to drain out such as cavity walls.

6. Dehumidifier - Wikipedia

   en.wikipedia.org/wiki/Dehumidifier

   A typical "portable" dehumidifier can be moved about on built-in casters. A dehumidifier is an air conditioning device which reduces and maintains the level of humidity in the air. [1] This is done usually for health or thermal comfort reasons or to eliminate musty odor and to prevent the growth of mildew by extracting water from the air. It ...

7. Building airtightness - Wikipedia

   en.wikipedia.org/wiki/Building_airtightness

   Conversely, poor airtightness may prevent achieving the desired indoor temperature conditions if the equipment has not been sized with proper estimates of infiltration heat losses. From an energy point of view, it is almost always desirable to increase air tightness, but if infiltration is providing useful dilution of indoor contaminants ...
