Guide D aims to provide guidance to practitioners involved in transportation systems in buildings; it will also be of interest to architects and developers, and to facilities and building managers who may not be directly concerned with the design and installation of lifts and escalators but need to understand the advice offered to them by specialists. Not least, the Guide should also be of value to students embarking on a career in mechanical, electrical or building services engineering and those already practising in these disciplines who wish to enhance their knowledge through a programme of continuing professional development.

Guide D was first published in 1993 under the encouragement of Peter Day of Land Securities. It then stood beside the three CIBSE Guides – A, B and C – which CIBSE published at that time. The success of Guide D has spawned a whole raft of CIBSE Guides on various topics. Updating of Guide D has continued on a five-year cycle, with revised editions published in 2000, 2005, 2010, 2015 and now 2020, with Dr Gina Barney as Technical Editor.

This edition of CIBSE Guide D has once again been brought up do date to keep it fresh and especially useful. This has been achieved by the expert efforts of the many authors, contributors and reviewers, as well as CIBSE staff. Through the years many individuals have given their time and knowledge freely and we owe all of them our heartfelt thanks.

Guide D provides a one stop shop for general information related to vertical transportation for the practitioner. It should be especially of use to persons setting out on a career in the industry. Educators will find It forms excellent support to deliver training courses.

Some things change slowly, such as components, whilst others, such as drive systems, continue to evolve. Since 1993 the Guide has grown in size to accommodate the increase of knowledge. Because it is written by experts it has become highly regarded and authoritative the world over.

However, all users must keep in mind that Guide D is just that, a guide. It provides guidance and recommendations. It is not a standard. Every effort has been made to ensure, as far as possible, that this Guide maintains this distinction when referring to standards. Where standards are mentioned, generally in an extracted form, and guidance is offered, it is always wise for the user of this Guide to read that standard for themselves, in order to check it addresses their requirements.
