👉 Indoor engineering, also known as building services engineering, focuses on the design, installation, and maintenance of systems that support the functionality, comfort, and safety of indoor environments. This includes HVAC (Heating, Ventilation, and Air Conditioning) systems for temperature and air quality control, plumbing and drainage systems for water management, electrical systems for lighting, power distribution, and safety, and structural engineering elements that ensure the building's integrity. Indoor engineers also address acoustics, lighting design, and fire safety measures to create healthy, efficient, and aesthetically pleasing indoor spaces that meet the needs of occupants while adhering to building codes and sustainability standards.
