Austrian Embassy Bangkok

With the Project:
Flagship environmental protection project Austrian Embassy Bangkok

The building of the Austrian embassy in Bangkok is a showcase in terms of environmental protection, energy efficiency, increase in life quality and simultaneous preservation of resources. By using new technologies, conserving the significant tree population and the transformation of traditional methods into innovative building techniques, the architecture proves cultural sensitivity and spirit of innovation. The use of a photovoltaic system on the shady flying roofs in combination with the optimisation of the energy consumption and a new ventilation system guarantee energy efficiency of the building ensemble and a pleasant room atmosphere.


The existing building which had been in use by the embassy, exhibited bad lighting conditions, inefficient air-conditioning and too little space despite of a previous extension of the building. This prompted the Austrian Federal Ministry for Europe, Integration and Foreign Affairs to organise a call for tender in which 90 international architecture firms participated, and HOLODECK architects was the winner. Important criteria were construction in the tropics, future viability, cost effectiveness in terms of erection and operation, access and security zones, open spaces, a multifunction room and a good workplace atmosphere.


The building ensemble consists of five individual buildings, forming a group round several courtyards. Two flying roofs provide shade for the gap between the buildings and serve as support structure for the large-scale photovoltaic system with an area of 590 m². Inverters provide the offices with the produced energy. There is no need for temporary storage of the energy in batteries since the office premises are cooled during the day. On the weekend, the generated energy is fed into the public grid. The three courtyards are home to 13 trees, some of which were planted after completion.


This project was realised considering the high Austrian standards as well as the difficult local conditions. Traditional decorative ventilation elements were used to ensure good air circulation during the seasons with high humidity and heat. Outstanding innovations are the ventilated photovoltaic roof, the central ventilation machine with sensors, the gradual supply with cooled fresh air and cold recovery, the biological treatment plants, the facades permeable to air, and the drainage system.
