Welcome to EEC
We are Engineer

EEC Engineering Network
We are EEC, We are Engineer

Since the establishment in 1976, Environmental Engineering Consultants (EEC) ambition is to be a world-known Thai engineering consulting firm. Starting from an initial group of five employees and now, over 200 employees. The founder Mr. Chaiyan Salicupt had a clear vision for EEC to become a leader in the environment field. Today, with a new name “EEC Engineering Network”, we are a leader in sustainable and green building design. “Co-operation and Networking” are the key of our business where we work with clients, architects, other engineering and local and international consulting firms to achieve this vision. As a learning organization, EEC Engineering Network is a knowedge-based group of companies with strong expertise and efficient teamwork to ensure that our commitments to our clients are successful and satisfactory.

EEC is well-known in leading energy efficient, environment, fire safety and innovation. EEC also has supported the government organization such as public work, town and country planning, Bangkok metropolitan authority, ministry of energy, ministry of science and technology, ministry of industry, ministry of environment and national safety council.

Our Vision

Though we are proud on our long >45 years of experiences, we are aware that we should foresee as multiple perspectives and always exploring advanced and practical future technologies. Building construction is no longer based on 4 basic elements but evolved with another, the 5th element.

Green & Sustainable Concepts

Today, continuing that vision, the spirit within us continues on with “Green and Sustainable” design concept A lot of EEC post references well demonstrate our practice in energy efficiency, environmental and safety design.

Happiness is proven by the long term staff

EEC is a family, brothers and sisters like society. We value seniority and many staff lives in EEC for more than 20 years. We emphasize staff engagement and as well offer career development.

Sustainable Building Design Services

EEC Provide design and consulting services for sustainable building design. From experience in building system engineering design For building certification in various criteria such as TREES, LEED, DGNB, WELL

Building Information Modelling (BIM)

EEC renders building design service using Building Information Modeling (BIM) to illustrate complete design concept both in 2-Dimension and 3-Dimension. BIM is also applied for the purpose of coordination during design stage to allow efficient control of work quality and input of information into the model to ensure correct and accurate information transfer.



RISC by MQDC with EEC Launches Negative Pressure ER with Fresh Air in Emergency Rooms to Help Hospitals in the COVID-19 Outbreak

“RISC by MQDC and its network of partners committed to enhancing quality of life and well-being aim to contribute to society and help address the widespread COVID-19 outbreak. Medical teams are facing a lack of safe working space and shortage of ER facilities for critically ill patients who need operations. ‘Negative Pressure ER’ can accommodate patients who need urgent treatment. Supporting emergency procedures for ‘Red’ patients on ventilators is crucial, relieving the shortage of ER rooms and providing flexibility for frontline personnel by helping support and create safe confined spaces.”
