CIBSE GUIDANCE | GUIDE D: 2020 remote alarms has been moved to chapter 7, and the principles of surveys has been moved here, from chapter 4. Much new content covers the rapid progress of technology in communications, the internet of things, cyber security, data logging, and Voice over Internet Protocol. Proper commissioning, and thorough examination, inspection and preventive maintenance of lifts, escalators, moving walkways, lifting platforms and stairlifts is critical to maintaining the safety and capital value of these assets. These issues are dealt with in chapter 15, which has been revised extensively and structured around new headings and sections. It incorporates the requirements of SAFed Lift Guidance 1 2020. Chapter 16 deals with upgrading the safety, performance and equipment of existing lifts. It examines the reasons for upgrading, which can range from improving the reliability of the lift, its aesthetic appearance, or obsolescence of key components. The performance upgrade can be in terms of the systems traffic handling, ride quality or energy consumption, or improving the safety of the equipment. This chapter has been updated to align with current thinking and standards, references have been updated, and the format of the tables improved. Safety rules for the construction and installation of lifts and escalators, specifications, codes of practice, commissioning recommendations, and safe working are covered by an extensive range of British, European and international standards and codes. Chapters 17 and 18 give an overview of some of these documents, and there is a comprehensive list of legislation, standards, codes of practice and so on in Appendix A1. Appendix A3 has an extensive glossary of terms. Other sources of information CIBSE Guide D contains references to other sources of information, particularly British Standards, associated standards and codes of practice. These should be consulted alongside the guide and other relevant publications.
