The feasibility of using a photoelectric cigarette smoke detector for energy efficient air quality control.

The object of this study was to determine the feasibility of using a smoke sensor to monitor and control cigarette smoke levels in occupied spaces and also to determine whether the use of such a detector could result in energy savings. A smoke detector was built and tested. The experimental results show that the smoke sensor output is a function of cigarette smoke concentration and that the smoke sensor gives a rapid and continuous response.

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. 

Air quality control - measurements and experiences.

Too high a concentration of certain gases (e.g. water vapour, carbon dioxide, tobacco smoke, alcohol, etc.) in public buildings can damage the health. Even low concentrations can cause discomfort and make the room air seem unpleasant. This paper describes this subjective perception of air qulaity. It is shown that installation of an appropriate sensor can make substantial energy savings.

Pollution by tobacco smoke of indoor air. Verunreinigungen der Raumluft durch Tabakrauch.

Indoor air pollution is particularly noticeable today, resulting from the improvement of ventilation in building envelopes in order to economise in heat energy, and the consequent reduction of fresh air entry, leading to poorer air quality. The article describes the effect of tobacco smoke on the indoor climate of residential and office buildings and its effects on health, particularly its effect on non- smokers, or the passive effects of smoke.

Pollution begins at home.

Points out that increased thermal insulation and draughtproofing of homes can increase the risk to health of indoor air pollution. Includes condensation as a pollutant along with associated mould growth. Notes collaboration by Pilkington the glass company and the Timber Research and Development Association plus Laing the housebuilding group, to combat condensation by passive ventilation. Treats sources of indoor air pollution - formaldehyde, asbestos, gas appliances, tobacco smoke, thoron, radon.

Indoor air pollution and housing technology.

Reviews the scientific literature on indoor air pollution. Low-pollution design and construction techniques employed in the Sunnyhill Low-Pollution Research Centre are outlined in detail and suggestions are made on their applicability to new and existing housing in Canada. The study recommends a four-fold approach to the indoor air pollution problem by government and the building industry: A) short-circuit major potential hazards, B) deal with low-pollution housing needs, C) spread and apply present knowledge, and D)foster more research and discussions on regulation.

Indoor air quality. Raumluftqualitat in Aufenthaltsraumen.

Covers maximum permissable levels of various substances, including tobacco smoke, asbestos and benzole, found indoors. The reduction of formaldehyde levels is given special attention.

Indoor air and human health

Covers indoor pollutant levels and their health effects in humans and animals for five principal classes of pollutant: radon, microorganisms, passive cigarette smoke, combustion products, and organic compounds. They are examined from viewpoints such as measurement and source characterisation habitat studies, health effects, risk analysis, and future needs.

Air pollutant emissions, concentrations, and exposures from biomass combustion: the cigarette analogy.

Examines four pollutants found in significant amounts in biomass smoke: respirable particulates, carbon monoxide, formaldehyde and particulate benzo(a)pyrene, to effect a comparison between tobacco smoke and biomass fuel smoke. Nominal doses of formaldehyde and carbon monoxide are roughly similar. For respirable particulates, smokers receive more than a factor of 10 larger nominal doses. The reverse is true for benzo(a)pyrene.

Indoor air quality and human health.

Provides general information on indoor air pollution sources, the pollutants commonly found indoors and their potential health effects. Contains chapters on formaldehyde and other household contaminants, radon, particulates, combustion products, smoking, energy-efficient buildings, control of indoor air pollutants, air quality in office buildings, and legal and regulatory issues in the USA. Further sources of information are given.
