Natural ventilation in non-domestic buildings : CIBSE Applications Manual AM10

This Applications Manual was first published in 1997 with the aim of 'providing more guidance on energy related topics in order to realise quickly the improvements in energy efficiency which should arise from the application of the guidance presented'. Much has happened since 1997 in relation to energy use in buildings. The Energy Efficiency Best Practice Programme which sponsored the first edition has been replaced by the Carbon Trust, which has become very widely recognised for its high profile campaigns raising awareness of business use, and waste, of energy. Part L of the Building Regulations, Conservation of Fuel and Power, has been transformed and will shortly be revised once more as Part L (2005). The Energy Performance in Buildings Directive has been adopted by the EU, and will be implemented in the UK from the start of 2006. And, late in 2004, the Sustainable and Secure Buildings Act reached the statute book, to enable Building Regulations to address these two, sometimes conflicting, themes.In the light of all these changes, as well as the growing practical experience of advanced naturally ventilated buildings, it is timely to issue a revised edition of this guidance. The principles remain largely unchanged — as do the laws of physics on which they depend. However, experience in their application has advanced, and new examples have appeared. As a result, the material has been re-ordered, and the examples, instead of standing alone at the end, are now incorporated within the guidance at appropriate places. This edition also draws extensively on work funded by the Partners in Innovation scheme of the DTI on automatic ventilation devices. The guidance contained within this edition will enable practitioners to apply the principles of natural ventilation based on a sound understanding of their underlying basis. In so doing further improvements in energy efficiency will be achieved.The revision has been undertaken by one of the original authors, Steve Irving, aided by David Etheridge and Brian Ford of Nottingham University. The revision has again been steered by a small group of leading practitioners from a range of professional backgrounds, with the aim of producing guidance that is as far as possible accessible to architects and engineers alike, and will assist them in adopting an integrated approach to building design.
