Airport Terminals


Airport sustainability and environmental impact

  • Rising cost of energy – 30 to 60% of airport terminal costs are associated with cooling
  • Load issues – predictability of capacity
  • Public scrutiny and expectations of airports on emissions and energy use.


  • Solar energy from panels on the roof of a terminal, power a standard water chiller which freezes PCM in thermal units ® below the concrete slab of the building.
  • The continuous freezing and melting causes heat transfer which cools the environment to a consistent ambient temperature
  • With highly efficient technology, 3 hours of sunlight can cool the terminal for 2 days (without any additional external source of energy).
airport efficient climate control


  • Thermal power is stored in the PCM floor units during the day at – 18C; stored to cool down the environment 24/7
  • A four-inch-thick layer of PCM can keep the environment cool for 2-3 days with insufficient sun


  • Net positive energy outcome with High Return on Investment (ROI)
    – 30% of the solar energy generated is required to cool the environment for 1 to 2 days.
    – Excess 70% solar can be used for lighting/stored in batteries or sold back to the grid
  • Clean and sustainable energy source – State of art design, featuring:
    – Built in humidity control (condensation can be evacuated or captured)
    – Incorporated air circulation system
    – Silent and sleek design whilst providing for an ambient environment
  • Durability – PCM has a life expectancy of 50 years
  • Standard easily sourced components
  • Safe – Non-toxic, recyclable and non-flammable
  • A robust corporate social responsibility plan
