BUILDING CONFIGURATION
The Terminal building requires to have large hall area without concrete pole or with minimal concrete pole for passengers’ convenience. For maximum passengers comfort with ease of traveling within the airport compound, the building comprise of two sectors, the Terminal and Concourse building. The Concourse building is for airplane connection to boarding bridges. The Terminal building is for handling departure and arrival passengers.
For energy saving purpose, the airconditioning will be provided only from floor level to 3 or 4 meter above the floor since passengers will not stay higher than 2 meters above the floor

7. CONCEPTUAL DESIGN FOR ENERGY SAVING OF SUVARNABHUMI AIR CONDITIONING SYSTEM
Usage of direct sun light with minimal electrical lamps during day time.
Air conditioning will be provided only from floor level to 3 or 4 meter above the floor to reduce the air conditioning load by means of Stratification technique. This technique use Radiant Floor Cooling together with Recirculated Air Cooling System.
3. Control intake fresh air for continual changing number of passengers.

4. Adjust Variable Chilled Water Volume for continual changing cooling load.
Use Chilled Water Temperature Difference ( delta T ) larger than normal conventional type which will require lesser pipe size and flow rate, thus reduced the pump size and energy required.
Reduce make up water of Cooling Tower by way of water filter instead of bleed-off
7. Reduce solar heat gain through glass by way of using Frit, a small circular pad, spread evenly on glass which help reduce the Solar Factor

8. Reduce infrared radiation from ceiling and wall by way of applying Low-E Infrared Hard Coating on ceiling and wall.
Reduce convective heat gain from electrical lamps since the heat gain will be combined with hot air above stratification level which will cause no effect to passengers.
Reduce radiation heat gain by way of using radiant floor cooling together with conventional air conditioning system.

AOT purchase chilled water from DCAP (Districted Cooling System and Power Plant Company Limited). DCAP has installed 8 ABSORPTION CHILLERS at CENTRAL PLANT located within Parking building next to the Terminal building. DCAP installed 4 ABSORPTION CHILLERS ( DOUBLE EFFECT TYPE ) on each plant (EAST and WEST PLANT) and each absorption chiller has the capacity of 2,100 TR (norminal) and can produce 706 m3/hr ( L/S) chilled water at return temp. of 14 C and supply temp. of 5 C
