Viettel HQ makeover utilising ABB’s tech

Viettel headquarters boast smart building technologies thanks to ABB’s innovative solutions

“As a technology leader in the country, Viettel aimed to develop our headquarters into a symbol of innovation so the technologies we use must help us to achieve this objective, ensure operational reliability, and bring the most comfort to the people working in the building in the digital age. For this reason, we chose ABB,” said Ha Quang Huy, director of Real Estate Management at Viettel Group.

Located on a golden land plot in Hanoi, the Viettel base overlooks a 32-hectare park including 19ha water surface of a lake. Becoming functional in late 2019, the building accommodates Viettel’s key business functions with around 1,000 employees. Viettel Group’s ambition in this move is to ensure its headquarters in Vietnam become a standard for other Viettel buildings across the world.

“ABB is proud to be a partner of Viettel Group on this innovative building project and to contribute to the greener, safer, and smarter operation of their new headquarters. With ABB’s solid track record for smart buildings in Vietnam, we will continue to help investors achieve a green footprint,” said Doan Van Hien, sales director of the electrification business of ABB in Vietnam.

ABB’s supplied technologies include medium-voltage switchgear Unisec, type-tested low voltage switchgear, System Pro E Power, and dry transformers. The dry transformer is a high-efficiency solution that supports Viettel to minimise environmental contamination and fire hazards for the structures.

Manufactured in accordance with international standards, it is virtually maintenance-free. Containing no oil, the transformer is ecological and many of the integral parts are fully recyclable, which fits with the “using clean and renewable materials” motto of Viettel’s office project.

Meanwhile, ABB System Pro E Power, an innovative main distribution switchboard solution, fulfils all electrical installation requirements in terms of protection degree, segregation form, and electrical characteristics. In addition, the system brings perfect synergy with all of ABB’s low voltage equipment to meet the reliability and efficiency that building operators expect.

In order to meet the high demand of safe, smart, and connected workplaces for a dynamic and creative working environment, Viettel’s headquarters are equipped with the most innovative solutions for smart building control including the well-established ABB i-bus® KNX system and HVAC ACH580 drives.

In the innovative ABB i-bus® KNX system, all devices of the building ranging from lighting and shutter control to heating, ventilation, security, and energy management communicate with one another via a single bus interface which is installed alongside the normal power lines.

Thanks to this system, the Viettel office becomes easier to manage and control by delivering increased flexibility, security, economic efficiency, and convenience. The operational flexibility of the installation allows working routines at Viettel’s office to be adapted easily and comfortably to the needs of the building occupants.

ABB’s ACH580 drives are the next evolution in the speed control of electric motors used for heating, ventilation, and air conditioning applications. With precise control, the motors only use the energy required to produce the air or liquid flow, so no electricity is wasted. Thanks to the drives’ ultra-low harmonic version, excessive electrical disturbances in the grid are avoided to ensure continuous operation.

The drives’ HVAC-specific functionality, such as built-in override mode, helps the customer overcome fire emergencies in the building, increasing safety of the occupants and property. Meanwhile, integrated BACnet connectivity allowed the drives to easily and cost-efficiently become part of the building automation systems.

Throughout its 25-year growth journey in Vietnam, ABB has become well-presented in the smart building sector with many other iconic projects such as Vincom Landmark 81 – the tallest building in Southeast Asia, Keangnam Hanoi Landmark 72, Times Square, VietcomBank Tower, and Thao Dien Pearl. ABB’s KNX system is used widely in important buildings such as the National Assembly Office, the headquarters of the Ministry of Foreign Affairs, Army Television Tower, the Presidential Office, and more.
