The main reason is really not the design but rather the cutbacks, cutting corners, and the biggest of them all: CORRUPTION. TIT

The infuriating aspect of your comment is that you haven't the slightest clue as to what you are writing about. You are wrong. The current airport temperatures consistently meet or exceed the building specs. Do you even know what the specs were? No you do not, but here you are to pass judgement and demean and insult the engineers who satisfied the design requirements.

BKK was the largest Green Building project of its day, and the airport was built to intentionally have two zones, with one cooled and the other not cooled. It was intended to save energy and to reduce the impact of energy generation pollution. On that basis, the airport has been a success. BKK was also the largest radiant cooling project of its time.

WSP USA, formerly WSP Parsons Brinckerhoff offers the following facts; When designing the HVAC systems for the airport, our engineers were faced with the task of mediating between Bangkok’s typical climactic conditions (77º-90º F and high level of relative humidity all year) and the airport’s demand for 24-hour working days and high internal heat loads from people, electric equipment and lighting. We were eventually forced to develop a technique that would account for the environmental intangibles, while still meeting the 75.2º F room temperature requirement. One strategy used to address such a concern was to split the airport into two zones: an unconditioned zone at higher levels, and cooled occupied zones at lower levels; thus consuming mechanical cooling energy only in those areas where necessary, drastically reducing the total cooling demand. WSP USA designed the chiller plant to provide 20,000 tons of chilled water for the complex to air-condition roughly 4,300,000 square feet of building areas. The plant, located in a remote car park structure, is connected to the terminal building by an underground utility tunnel and distributed in the service and baggage handling levels of the project.


If you believe that corruption is not as pervasive and widespread in Hong Kong, Japan, Singapore and Korea then you are delusional. Construction and public works projects have always featured cronyism and corrupt government officials whether it is in the UK, Canada, USA, Australia or Asia. Sometimes these people are exposed and other times they just get away with it until they are caught poaching in a national park and cover up their misdeeds. The construction industry has been dirty since they built the pyramids.

Not sure where the complaints are coming from. If you’re an obese American or Australian who likes the A/C set to 18 maybe it’s too hot, but I come from a cool climate and go through BKK 40 or 50 times a year and have never felt hot or uncomfortable in the airport.
