HVAC is a major sub discipline of mechanical engineering deals with the technology of indoor air quality management of buildings and human comfort. HVAC system designing deals with heating, ventilation systems designing, air conditioning, refrigeration system designing and equipment selection.

This Diploma Certificate program covers the full design and analysis of Electrical Building Services from the fundamentals to Power System design, Wiring and Cable Management Systems, Lighting systems, Earthing Design and Calculations, Fire Alarm Systems, HVAC and STP Controlling Systems, Communication systems like Networking, Security Surveillance Systems like CCTV, Access control System etc.

Industrial radiography is the use of ionizing radiation to view objects in a way that cannot be seen otherwise. It is not to be confused with the use of ionizing radiation to change or modify objects; radiography's purpose is strictly viewing. Industrial radiography has grown out of engineering, and is a major element of nondestructive testing. It is a method of inspecting materials for hidden flaws by using the ability of short X-rays and gamma rays to penetrate various materials. Two ways to inspect materials for flaws is to utilize X-ray computed tomography or Industrial computed tomography scanning.

Visual inspection is a common method of quality control, data acquisition, and data analysis. Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of raw human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment. Inspections requiring Ultrasonic, X-Ray equipment, Infra-red, etc. are not typically regarded as Visual Inspection as these Inspection methodologies require specialized equipment, training and certification.
