CIBSE Natural Ventilation News - July 2011

Share this Post:

This Newsletter released by the Chartered Institution of Building Services Engineers (CIBSE) Natural Ventilation Group Management Committee, aims to inform members and potential members of the work being undertaken by the Group to benefit the discipline of natural ventilation within CIBSE.


Contents include:


  • The Delinquent Arrows.

An article discussing air movement in naturally ventilated buildings and the role of Computational Fluid Dynamics (CFD) in identifying how air flows within a building.


  • Natural Ventilation in the Urban Environment.

A summary report of a seminar held at the Royal Institute of British Architects (RIBA) on Friday December 3, 2010. This event set out to examine the issues and explore ways in which natural or mixed mode ventilation can be applied to buildings in urban areas.


  • Manual and Automatic Opening Windows go Head to Head.

An article based on a comparison study of the performance of a natural ventilation system with manually opening windows versus the performance with automatic opening windows. According to the results, automatically controlled windows provide natural ventilation that maintains an optimum Indoor Air Quality (IAQ) more efficiently than windows opened manually with no automatic control.
