BS 5925:1991 Code of practice for Ventilation principles and designing for natural ventilation

Author: Technical Committee BDB/2 | Size: 1.32 MB | Format: PDF | Publisher: BSI | Year: 1991 | pages: 48 | ISBN: 0580192857

This British Standard gives recommendations on the principles which should be observed when designing for the natural ventilation of buildings for human occupation. The standard is in three sections, as follows:
Section 1. General
Section 2 outlines the main reasons for the provision of ventilation and, where possible, recommends quantitative air flow rates. It is shown that these form the basis for air supply recommendations for different types of buildings and rooms characterized by usage. The basis for the choice between natural and mechanical ventilation is given. The design of mechanical ventilation systems is dealt with in BS 5720.
Section 3 gives recommendations on the design of natural ventilation systems and on the estimation of air infiltration rates in housing.
Appendix A is a bibliography and reference to publications listed in it are shown as:
(see Appendix A [15]).
Appendix B gives recommendations on evaluating contamination risks.
Appendix C gives recommendations on calculating ventilation rates to reduce the risk of surface condensation under steady state conditions.
Appendix D gives recommendations on determining ventilation requirements.
Appendix E gives recommendations on calculating reference wind speed.
Appendix F gives recommendations on calculating natural ventilation rates for a simple building.
This standard does not attempt to address thermal comfort aspects of ventilation such as indoor air movement, temperature stratification, exact position of ventilation openings etc.
NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
