The proper construction of an Electromechanical Installation requires excellent study and design. This, in turn, necessitates outstanding knowledge in interdisciplinary subjects such as energy issues, construction, as well as financial matters. These installations must be characterized by aesthetics, safety, and economy.

These requirements are met when the designer is knowledgeable about the relevant regulations, technical rules, and practical experience. This text aims to address this purpose.

In presenting the topics, particular emphasis is placed on the regulations and standards that apply to each section and are valid in Greek territory. Efforts have even been made to include all necessary elements (tables, diagrams, etc.) for processing each study, so that frequent reference to other sources is not necessary.

Thus, beyond being the primary aid for the lectures of the Electromechanical Installations course, this book aspires to also serve as a resource for the studying Engineer, who is practically involved in the studies of the Electromechanical Installations of buildings.

This edition includes the chapters: 1. Mechanical elevators, 2. Hydraulic elevators (based on the current EN 81-20 and EN 81-50 standards), 3. Water supply, 4. Sewage, 5. Fuel gas (based on the current regulation FEK 976/28.3.2012 and FEK 963/15.07.2003), 6. Electrical installations (high currents, description of foundational grounding), 7. Thermal insulation (based on the older DIN 4701/1977 and 1983 and based on the K.E.N.A.K. 2017 and the T.O.T.E.E. 20701/1,2,4 - 2017), 8. Heating (based on the older regulation according to DIN 4701/1977 and 1983 as well as with the K.E.N.A.K. 2017 and the T.O.T.E.E. 20701/1,2,4 - 2017).
