People and ventilation - considerations with regard to the economical application of engineering methods for ventilation. Mensch und Raumluft - Gedanken Zum wirtschaftlichen Einsatz luftungstechnischer mabnahmen.

Defines requirements for suitable indoor air quality and examines the technical and economical possibilities of suitable methods of ventilation. Differentiates between densely populated places (meeting places) and others of low occupancy, such as offices and living rooms. Finds that the most efficient way of satisfying hygiene requirements is by controlled air renewal, and that to achieve this mechanical ventilation according to DIN 1946 should be installed.

Effects of air supply rates on space energy consumption.

Describes an analytical model used to study the effects of air supply rates on the dynamics of an occupied space as related to energy consumption and occupant's comfort. Reviews the concept of Air Diffusion Performance Criteria (ADPI) and uses it to derive air movement control strategies to reduce energy consumption in buildings. Discusses the relationship between the air movement control strategies and passive thermal control strategies for energy efficient buildings.

Indoor pollutants.

The report was prepared, at the request of the Environmental Protection Agency by the Committee on Indoor Pollutants. It outlines the scope of the problems regarding indoor pollutants and discusses their sources, their effects on human health and welfare, the technologies available for their control or abatement, and concerns about the effects of energy-conservation strategies on indoor concentrations of pollutants. It approaches the subject of indoor pollution from three viewpoints: 1. Physical factors, such as indoor pollutant sources and concentrations. 2.
