Discusses how the design of modern swimming pool leisure complexes must adapt to the diverse demands of today's users. States that the air treatment in a covered swimming pool complex depends on a fragile balance between the demands of occupant comfort and the technical imperatives for the conservation of the building structure. It is also of utmost importance to pay particular attention to precisely quantifying the thermal needs, defining the air flow and thermal means of operation, and selecting a principle for dehumidification which is well-tuned to its application.
The National Death Index was used to monitor a cohort of 72,740 persons for whom information on household air conditioning was available, between April 1980 and December 1985. 2275 deaths occurred. The study attempted to establish whether people in households with air conditioning experienced lower death rates during hot weather. Both central and room air conditioning were considered.
Gives two examples at an air force base of poor maintenance of equipment. In the first study a comprehensive base-wide steam trap maintenance program is described. In the second a measured evaluation from a typical office building is described. The aim in both was to assess the importance of proper operations and maintenance, aiming in turn to provide more efficient building HVAC operation, provide improved services to the building occupants, and reduce energy consumption and unscheduled equipment repair/replacement.
The article presents IAQ requirements for healthy office buildings in Nordic climates, based on the results of an epidemiological study of a multistorey office building in Helsinki, Finland. Summarizes the results of the study and gives recommendations and their limitations.
An evaluation of the effect of air humidification on various factors was performed, including skin dryness and mucosa, allergic and asthmatic reactions and perception of IAQ. A six period cross over trial was conducted on 290 office workers. A total of 211 workers who returned at least two weekly diaries and who had experienced both humidified and nonhumidified conditions were included in the analyses. The main outcome was characterized by dryness, irritation or itching of skin and eyes, of the throat and nasal dryness.
Describes a study of air humidification in the Pasila Office Center, which is a modern eight-floor office buildings of 2150 workers in Helsinki, Finland. A comparison was done between the occurrence of symptoms and complaints among the workers in the humidified part of the building and the symptoms and complaints of workers in similar nonhumidified rooms during February, March and April. Significantly less dryness of skin, throat and nose and nasal obstruction as well as sensation of air dryness was reported by the workers in the humidified part.
In discussion with the person in charge of provision for the many swimming pools in the Paris region, both municipal and school, the article gives and overview of the problems to be tackled in terms of dehumidification.
