CIBSE Guide D: Transportation Systems in Buildings 2015

Download or purchase Guide D from the CIBSE Knowledge Portal

Since its inception, Guide D has become the de facto reference for many people involved in the broad and varied world of vertical transportation. The Guide provides the reader with a wealth of information and recommendations on key issues relating to vertical transportation systems. The Guide is not only a key source of information for those who work within the vertical transportation industry but is also a valuable source of information for architects, developers and those involved in the management of estates and individual buildings.

This fifth edition of CIBSE Guide D is the result of extensive review and revision by a dedicated and enthusiastic team comprising lift and escalator specialists and building service engineers. This Guide is very comprehensive, covering the whole spectrum of interior circulation, planning and design, selection of equipment and performance, computer programmes, types of systems, legislation, fire and safety, requirements for persons with disabilities, lift components, lift traffic controls, escalators and moving walkways (passenger conveyors), energy consumption, electrical systems and environmental conditions.

The purpose of  Guide D is to provide guidance to practitioners involved in such systems. The Guide should also be of interest to architects and developers, along with 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 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.

It is important that people, goods and equipment are moved safely and efficiently. This latest edition of CIBSE Guide D will help meet those objectives.
