air inlets

At present the design pressure difference for air inlets in The Netherlands is 1 Pascal. This paperinvestigates the question whether or not this value is still appropriate.In recent years the airtightness of dwellings has improved remarkably. Self adjusting air inletshave been introduced on the market. What is the effect of these changing building features onthe pressure difference over the building envelope?

Summarises research into the positioning of air intakes to avoid contamination of ventilation air. Based on current research, it attempts to demonstrate various ways in which the pollution at air intakes can be minimized at the design stage. Also doe those buildings which have become polluted, it discussed what actions are than available to reduce the contamination of the indoor environment.

Sauna is the Finnish word for a wood-lined and insulated room, heated by a special stove containing stones, and erected specifically to create the right environment for a certain kind of dry bath. lts fundamental purpose is to induce perspiration and thus to cleanse the skin and. body. The authors have now applied scientific data to the mystique and culture of the often misunderstood Sauna which has been used by the Finns for some two thousand years.
