Research on air infiltration, ventilation and indoor air quality in the Federal Republic of Germany.

In December 1985 the Federal Republic of Germany joined the International Energy Agency's Annex V, the Air Infiltration Centre, as the twelfth participant. This report describes and summarises German research and development activities in the areas of ventilation, air infiltration andindoor air quality.

A prototype ventilation system for superinsulated houses using forced air duct systems.

The Energy Division is working toward development of ventilation systems capable of providing acceptable levels of indoor air quality in superinsulated houses. The research was designed to analyze and improve the indoor air quality of a superinsulated retrofit house located in St. Paul, Minnesota. The occupants had encountered 'stuffy air' problems after their house was superinsulated and weatherized to reduce heat loss, and uncontrolled air infiltration. High levels of CO2 build up were revealed indoors, despite the presence of a continuously operating air-to-air heat exchanger.

Dust removal in living rooms. Zur Entstaubung der Luft in Wohnraumen.

Notes reasons for reducing dust concentrations in rooms - allergic reaction to pollens and mould spores, etc., plus the fact that viruses and bacteria and some substances causing smells are often attached to dust particles. 

Indoor air quality

Discusses the interrelationship of home ventilation rates, sources of air contaminants, and the relative quality of the indoor air environment, including: what is an unsafe air quality level? The problem in perspective, common household pollutants, home ventilation, identification and testing.

Ventilation criteria: biological demands and formulation of standards.

Methods of controlling indoor air pollution include control, air cleaning and dilution with uncontaminated air. Assessment of the amount of ventilation necessary depends on the extent of pollution, which has increased as new pollutants are identified and new materials are used. This has lead to thereexamination of ventilation standards and their underlying rationale.

The ventilation of buildings: investigation of the consequences of opening one window on the internal climate of a room.

The report of the investigation into the possibilities for saving energy by closing (large) windows in good time after, for example, the so-called 'airing' of bedrooms, initiated by the Netherlands Ministry of Housing and Environment's Steeri

The importance of indoor air pollution to personal exposures in developing countries.

Air pollution is not just a phenomenon associated with urbanization and industrialization. It is possible that the principal exposures to several important pollutants occur in rural areas of developing countries where the population relies on biomass fuels for their energy needs. These fuels have large emission factors for particulates, CO and a range of hydrocarbons. Rural studies have found very high BaP concentrations. Effects on health have not been researched, but can be assumed to be similar to urban occupational air pollution effects.

The importance of indoor air pollution to personal exposures in industrialised societies.

Indoor concentrations of a variety of particulate matter and gaseous compounds often exceed outdoor concentrations. We should examine exposures to air pollutants within the important built environments or perhaps on a personal basis. The development of reliable biological markers is still an area of active research. Instruments passively monitoring NO2 exposures over timeperiods ranging from hours to days have been used in several studies in theU.S.
