Construction projects and buildings are becoming increasingly complex, with more functions and higher demands requiring new solutions for operation. Facility Management is the answer to the questions regarding a modern supply system for buildings and facilities. Here, various systems converge and can be dynamically controlled. Standards regulate, as in other areas, the common standards, terminology, and requirements. This book brings together the most important standards that must be adhered to in Facility Management, placing a strong emphasis on the aspect of maintenance. Maintenance is a significant subfield of Facility Management and is addressed in a series of specific standards. The standards included in this book cover topics such as planning and requirements, definitions and fundamentals, contract design, monitoring, and energy efficiency. With its well-curated selection, the DIN Handbook 293 serves as a useful collection of standards for practical work in Facility Management. It provides the relevant documents in a handy A5 format for easy access.
