1-2 Transportation systems in buildings
to be used in fire and emergency situations. This chapter
has been extensively updated to include the recommen -
dations of the new BS 9999. Comment and guidance is
also provided on the use of lifts for general evacuation.
The principal components of lifts, including both electric
traction and hydraulic drives, are described in chapter 7.
It now includes safety devices to deal with uncontrolled
movement away from a landing with the lift doors open.
New sections are also included on inspection controls and
guarding.
Lift drive and control techniques are considered in
chapter 8. It provides an unbiased guide to controls and
drives to allow a better understanding for users and
specifiers to ensure they select the correct system for their
particular application. Comment on programmable
electronic systems in safety related applications for lifts
(
PESSRAL) is briefly considered.
Lift group traffic control is outlined in chapter 9 and has
undergone some revision for this issue. It provides
guidance on the traffic control of single lifts, and for
groups of lifts through legacy systems, based on relay
logic, to modern day systems, utilising microcomputers.
Several case studies support the guidance.
Chapter 10 discusses escalators and moving walks,
including their safety considerations. Escalator applica -
tions range from low-rise installations to accommodate a
small change in level within a story of a building to long
travel installations in deep underground stations. The
updated standard BS EN 115-1
(3)
and the forthcoming BS
EN 115-2 (prEN 115-2)
(4)
are also discussed.
Transportation systems in buildings should provide
independent and equal access for everyone. Chapter 11 has
been updated to include recently published standards and
provides guidance on the types of disability and design
issues that need to be considered along with the standards
and regulations that are applicable. A summary of BS EN
81-70
(5)
is also presented along with guidance on the
implications of the new Machinery Directive
(6)
.
Electrical systems and environmental conditions supplies
are discussed in chapter 12. This chapter examines the
provision of power supplies for the whole building and
guidance on key environment conditions, which should be
considered during the design process.
Lift, escalator and moving walk energy efficiency and
power consumption issues are discussed in chapter 13,
which addresses how energy consumption can be
minimised through good design, selection and control of
the transportation equipment. The current work at ISO
level is referenced along with guidance on the current
requirements of the BREEAM building classification
system.
Chapter 14 offers some guidelines on remote monitoring
and remote alarms and suggests ways in which the
resulting data can be used to improve the efficiency of
vertical transportation systems and their interface with
other systems within the building. The British Standard
protocol DD 265
(7)
for lift and rescue centres is described.
The proper commissioning, thorough examination,
inspection and preventive maintenance of lifts escalators
and moving walks is critical to ensure that the safety and
capital value of these assets are maintained. These
important issues are dealt with in chapter 15.
Typically, lift installations require upgrading after 15–20
years of service. Chapter 16 has been re-written and
examines the reasons for upgrading, which can range from
improving the performance in terms of the system’s traffic
handling, ride quality or energy consumption to improv -
ing the safety of the equipment. This chapter also includes
easy to read tables for upgrading existing traction and
hydraulic drive lifts and includes new guidance on
accessibility and vandal resistance considerations.
It is fortunate that safety rules for the construction and
installation of lifts and escalators, specifications, codes of
practice, commissioning recommendations and safe
working are all covered by an extensive range of British,
European and international standards and codes. Chapter
17 provides an overview of some of these important
documents. The chapter is supported by a comprehensive
and up-to-date (at the time of publication) list of
legislation, standards, codes of practice etc. in Appendix
A3. This annex also includes a list of interpretations to
some of the EN 81 family of standards
The Construction (Design and Management) Regulations
1994 signalled a clear message to all those working in the
construction industry that safety needed to be improved.
Chapter 18 provides a guide to the impact of the 2007 reg -
ulations
(8)
on lifts and escalators. The CIBSE is indebted
to the Lift and Escalator Industry Association (LEIA) for
permission to reproduce its guidance document.
Appendix A1 provides an extensive glossary of terms. This
is not limited to the terms used within this Guide but also
includes definitions of many of the terms likely to be
encountered when dealing with lift, escalator and moving
walk systems. The CIBSE is indebted to GBA
Publications for permission to reproduce this valuable
glossary.
Finally, a comprehensive index is provided.
1.4 Other sources of
information
It is hoped that this fourth edition of CIBSE Guide D:
Transportation systems in buildings will provide an invaluable
reference source for those involved in the design,
installation, commissioning, operation and maintenance
of transportation systems in buildings. However it cannot
be, and does not claim to be, exhaustive. The various
chapters contain extensive references to other sources of
information, particularly British Standards and associated
standards and codes of practice (see Appendix A3), which
should be carefully consulted in conjunction with this
Guide, together with relevant trade and professional
publications.
