Moisture Control Measures – Home with Basement

Solution Proposed following inspection bt Ray Hudson

Basement
The basement requires a constant mechanism of ensuring the removal of excess water by means of ventilation. Our objective is to provide an efficient drying solution that runs economically on a continuous basis without user intervention.

Air exchange over this area requires a powered intake and air extra system that encourages cross ventilation and drying process, this is enhanced with the incoming air conditioned to absorb moisture as it displaces the existing air, and then in turn is itself extracted. This means of moisture decantation is very efficient, providing a low energy unobtrusive mechanism that does not require user intervention.
The use of conventional dehumidifiers in parallel is not required. However some additional background heating will improve the rate of moisture extraction.

The most effective times of decantation by this mechanism for basements occurs when the external temperatures are less than the internal temperatures.

Utility area
An affective means of ventilation in this area is good practice and will make the occupants more comfortable while Ironing etc, and at the same time will reduce the effects of excess humidity processes, by reducing the amount of moisture migration to other areas through vapour pressure equalisation – high water vapour pressure > low water vapour pressure.

Bathroom – Main
Ventilation of these areas reduce moisture induced maintenance issues – particularly around the shower and bathing location.
As with all ventilation the replacement air source is as important as the extract air.
It is proposed that two ceiling vents are installed – one externally to the bathroom, providing replacement air (pre warmed), and one near or above the shower area.
This will provide exchange of air with the commensurate moisture decantation process occurring at times of moisture production and then as a low level continuous operation.

Bathroom – Area above main Kitchen.
Within the area of the hallway at the top of the stairs the air is being affected by the kitchen activities below. Humid air rises, usually along with vapour pressures of other constituents, evolving from cooking.
To best ensure an exchange of air and at the same time manage the bathroom condition the same solution as the main bathroom is proposed for this area.
