The stack effect provides the driving force for vertical air movement within buildings. Its effects are especially pronounced in high rise developments, where the air leakage associated with elevators, stairs and service shafts can be a major concern. Stairwells and lift shafts themselves provide occupant access to those floors above or below ground level as well as providing routes for the movement of air. A knowledge therefore of the air movement characteristics if such shafts is vital in understanding the ventilation and leakage patterns in medium and high rise buildings.
Summarises research into the positioning of air intakes to avoid contamination of ventilation air. Based on current research, it attempts to demonstrate various ways in which the pollution at air intakes can be minimized at the design stage. Also doe those buildings which have become polluted, it discussed what actions are than available to reduce the contamination of the indoor environment.
Provides a platform for the dissemination of information related to infiltration, ventilation, indoor air quality and energy use within buildings by means of a survey and analysis of current research. The current survey reports on research projects from over 250 sources worldwide. The sections include an analysis of the results of the survey, a detailed list of survey replies, which is also available in searchable database format, and contact names and addresses for researchers.
Discusses the issues which influence the performance of heat recovery devices within typical building applications. It is intended to cover the three main types of devices installed in ventilation systems in residential and commercial buildings.
An introduction to the Internet which illustrates the range of information available and shows hoe in a short time it is possible to become connected and operational on the Internet. The services offered include e-mail, the ability to tap into vast sources of data, and the opportunity to establish one s own information databases for either general or restricted access. Energy efficiency related homepages include the US DOE CADDET and various IEA programmes and annexes.
In the Netherlands, many attempts have been made to introduce and implement advanced energy efficient domestic ventilation systems. This especially applies to balanced ventilation with heat recovery, one or multizone air heating systems with he
The ventilation standard was investigated in a large number of school buildings located in Gothenburg, Sweden as part of a current large-scale renovation programme. This article reports on experiences from the reconstruction work involved. Results from air quality measurements comprising TVOC (total volatile organic compounds) and CO2 measurements are presented. The results show that the indoor air quality is considerably influenced by outdoor contamination sources and that cleaning products and floor polish can, temporarily, add to the pollution content in classrooms.
Describes the Orkney Housing Association (OHA) Low Energy Housing Pilot Project, which demonstrates that it is possible to construct airtight buildings in the UK with minimal additional expenditure. This involved careful planning, the incorpora
