As well as being involved in the design of building systems, you could also write related software, produce control system graphics, and be involved in the installation and maintenance of control systems. As technology evolves, more buildings are connecting and integrating electrical, mechanical, and security systems to create ‘Smart Buildings’. So you could get involved in analysing data and developing very energy efficient environments.
Industrial, commercial and public buildings all have mechanical, electrical, and HVAC (heating, ventilation and air conditioning) systems, which are used to create safe, comfortable, and effective operating environments for people and products.
