Measurements of air change rates, carbon dioxide concentrations, room air temperatures and relative room air humidities in bedrooms of five well tightened dwellings were carried out in October 1989. With the results of the measurements and also based on simulation calculations, recommendations for an optimal window opening behaviour in bedrooms with the intention of saving energy and of providing sufficient indoor air quality were made.
Ventilation efficiency may be defined as the capability of a given ventilation system to achieve the best balance between indoor air quality and energy conservation requirements:
Keynote speech describes the difficulties of designing air conditioning system with human comfort in mind. Lists design fundamentals for satisfactory indoor air quality, together with a description of some case studies.
Management for acceptable indoor air quality in office buildings requires that the buildings are properly designed, operated and maintained, and that property managers have the knowledge necessary to respond to changes in building operation and use. Although most property managers are non-technical people, with clearly defined guidelines they are capable of achieving this objective. This paper presents an IAQ guide for such a purpose. The guide has been tested by four property managers for accuracy in detecting potential problems and ease of use.
