Concordia may be the newest international school to Hanoi, but we bring over 150 years of educational experience to Hanoi. Concordia is part of the Lutheran Church- Missouri Synod (LCMS) in the United States. The LCMS has been actively developing schools in the United States since the 1860’s and throughout Asia for the past 40 years. Concordia Hanoi is modeled after our two sister schools: Hong Kong International School, and Concordia International School – Shanghai, China.

The Hanoi school concept developed out of a number of different invitations and possibilities throughout Asia. Vietnam was selected as the primary site for the next LCMS international school since the LCMS NGO, headed by Ted Engelbrecht and his staff, have been successfully working in Vietnam for the past 13 years. There is also a great need for education generally and for international education specifically in the city of Hanoi. In addition, the people within the U.S. Embassy and the business community expressed a desire for a school like HKIS and CISS to come to Hanoi: a high-quality, values-based school that could serve the foreign and American populations as well as local students.

In the fall of 2006, the leaders of LCMS World Mission team visited Hanoi with Dr. Allan Schmidt and Dr. Greg Sawyer for an assessment and validation of the opportunities presented to the LCMS. A feasibility study was completed in November of 2007. The study looked at both Ho Chi Minh City and Hanoi. Strong evidence of need and opportunity pointed to Hanoi. In the spring of 2008, LCMS leaders came to Hanoi to meet with government officials. Some attended a reception for Vietnam and US government officials, educational leaders and corporate leaders in Hanoi held by U.S. Ambassador Michael W. Michalak. Over seventy people listened to Ambassador Michalak extol LCMS schools in the U.S. and abroad.

The writing of many documents for the application to the government of Vietnam was in the process for the next two years. Some of the documents included were a PS-12 curriculum, a feasibility plan, a charter application, a financial plan, a temporary building plan and/or permanent location plan for the proposed school. After several revisions and adjustments, the application was accepted for review by the Hanoi government and the Ministry of Education and Training of Vietnam. After numerous meetings, resubmissions, and clarifications, Concordia received approval to open by the Hanoi’s Peoples Committee.

Concordia is excited to start a new chapter in the long history of LCMS education.

Concordia's Green Scheme

Leadership in Energy & Environmental Design (LEED) Practices

Green Practice:

At Concordia International School Hanoi, we define sustainability as the economic state where the demands placed upon the environment by commerce can be met without reducing the capacity of the environment to provide for future generations and economies.  

Concordia’s dedication to reduce our environmental footprint is exemplified by the commitment to sustainability through gold-level application in the U.S. Green Building Council’s LEED.

Concordia's effort to sustainability is reflected through the design, build, and operate stages.


Careful research and planning allowed Concordia to embed sustainable features into the space before construction was ever started. Sustainable planning activities in the concept and design stages were crucial to building Concordia. Green design optimizes indoor environment, resulting in a healthy and comfortable indoor condition to guests.

Air Quality Control

  • Ventilation meet the minimum requirement of the ASHRAE Standard 62.1-2007, improving indoor air quality and promoting occupant comfort, well-being, and productivity. 
  • Low VOC supplemental material were used to achieve more healthy indoor environment.

Water Saving

  • Water efficiency fixtures were applied to reduce 40% of water use when compared with US EPA standard.
  • Local plant species were planted, reducing permanent watering needs. 

Maximize Open Space

  • The project has been designed to maximize vegetated open space to promote biodiversity.


Selection of Site

  • The location encourages the use of public transportation as it is surrounded by bus and subway stations, thus reducing pollution produced by private vehicles.

Construction Indoor Air Quality Management Plan

  • Partitions and protection are implemented to obstruct pollution source spread.
  • HVAC duct and indoor environment is protected during construction stage.

Regional Materials

  • Over 10% of the building’s products and material are from within 500 miles to support the regional economy and reducing the environmental impacts resulting from transportation.

Systems – Lighting Controllability

  • Individual lighting controls enables occupants to adjust the lighting system that meet needs and preferences.


Material and Indoor Air Quality 

  • To ensure sustainable indoor air quality, all material used to build the school is within the allowable VOC limit, such as adhesives and sealant products, painting and coating products.

Thermal Comfort

  • In order to provide a comfortable indoor thermal environment that promotes occupants’ well-being, 100% of the occupants have access to individual comfort controls for meeting individual needs and preferences.

Protection of Natural Environment

  • The project uses refrigerants and HVAC&R that minimize the emission of compounds that contribute to ozone depletion and global climate change.

Water Use Reduction

  • Water use reduction strategies are employed to reduce water use when compared to water use baseline calculation for building.

Energy Conservation

  • At least 10% improvement in the proposed building performance rating is achieved to optimize energy performance when compared with the baseline building performance rating.

Green Education

  • The school seeks to communicate our efforts and success to the public, to spread education about sustainability and green built environment.
