The main purpose of NCTESs design and implementation of Heating, Ventilation and Air-Conditioning (HVAC) system is to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in any premise. The choice and design of the HVAC system makes the difference in any living and working environment. This is why we strive to design quality systems.

That is cost competitive while successfully providing an appropriate quality air, lower energy costs, and easier maintenance.

The plumbing industry is a basic and substantial part of every developed economy due to the need for clean water, and proper collection and transport of wastes. Given the importance of water in our lives, our designers and installers are extremely careful in the treatment of a resource that is scarce worldwide. Team DOUMMAR puts lots of emphasis to ensure we provide a plumbing where pipes, drains fittings, valves, valve assemblies, and devices we install in a building for the distribution of water for drinking, heating and washing, and the removal of waterborne wastes are well sized and securely installed.

Fire protection:

Our purpose behind our Fire protection practice is based on three vital goals: The continuity of operations, property protection and last but not least life safety. DOUMMAR’s team intend in their engineering of fire protection systems to prevent the interruption of critical services necessary for the public welfare and to prevent area wide conflagrations, all with life safety as the ultimate goal.

  3. Backlights
  4. Path lights
  5. Specialty lights

F) Emergency Lighting Systems

Emergency lighting refers to light fixtures whose purpose is to illuminate the exit pathway of a building in an emergency situation when AC electrical power is lost. During such emergencies, normal lighting systems cease to operate and emergency lighting systems turn on.

  1. Central battery system
  2. Maintained lighting fixtures
  3. Non maintained lighting fixtures

G) Lighting Control Systems

Lighting control systems are used for working, aesthetic, and security illumination for interior, exterior, landscape lighting and theater stage lighting productions. They are often part of sustainable architecture and lighting design for integrated green building energy conservation programs.
