An introduction to earthing, lightning protection and EMC requirements for a building

The subjects of earthing, lightning protection and EMC are often misunderstood but are critical aspects of building design. This one-day course sets out the requirements of BS EN 50522, BS EN 62305, the relevant EMC standards, directives and UK legislation. The main design considerations are described and are brought together in a case study showing how these three aspects can be coordinated during the design of a building to improve performance and cost-effectiveness.

Consideration of these three critical aspects early in the design process can avoid significant problems during construction and operation of the building. This is key for the safety of occupiers and for immunity to interference of electronic equipment.

The course will provide a useful overview of earthing, lightning protection and EMC to those involved in all aspects of building design, project management or construction across all sectors. On completion of the course, each delegate will have increased awareness of these subjects, the key requirements and typical design activities associated with them.
