dehumidification

Discusses methods of preventing condensation: dehumidification, ventilation, controlling vapour flow; insulation and heating. Particular attention is paid to interstitial condensation and condensation in roofs

Describes the physics of moisture in the home. Suggests four basic strategies for dealing with excess moisture buildup in the home: 1) minimise the entry and release of moisture, 2) protect building components with vapour barriers, 3) remove water vapour with ventilation or dehumidifiers and 4) raise theinside surface temperature of windows.

Ventilation is a key factor in low energy housing and in temperate maritime climates such as Britain's moisture is a major factor in determining ventilation needs. Outlines necessary levels of humidity for both people and buildings. Summarises sources of moisture. Discusses control of humidity by either mechanical ventilation or heat pump dehumidification.
