The moisture load in dwellings as a function of the layout of the rooms shown by ground plans.

Measurements in some dwellings show differences of the absolute humidity as a function of the kind of ventilation (only natural or mechanical exhaust air or balanced ventilation) and the position of the single rooms, especially of the bedrooms. Therefore is investigated into the expected moisture transport in two different ground plans. The main humidity production is in the kitchen and bathroom. If kitchen and bathroom are on the outer side, the dwelling is loaded with this moisture through the main wind direction. This counts especially for bedrooms, because through this moisture load on the day there can appear peaks in the night. By the right layout of these rooms in the ground plan you can relieve the dwelling of moisture load as far as possible. If kitchen and bathroom are in the interior of the dwelling, only the effectiveness of the natural or mechanical exhaust air counts for the transport of moisture. By the right construction of the exhaust air, this air can reduce the moisture even in the living- and bedrooms.
