11ENERGY-EFFICIENCY
12Construction Practices
• Reduction of heat transfer at the roof and walls in the
terminal, using high-performance materials with a heat
transfer coefficient less than 0.33.
• Construction and operation of a Trigeneration plant.
13TRIGENERATION PLANT
14Legal Framework
Political Environment
The cogeneration is governed by the decree 3232 dated on 3 December 2002, that allows, for
industrial and tertiary sectors, to produce, simultaneously, thermal energy and electrical
energy from a primary energy and inject its surplus power on the national grid upon the
respect of the following conditions of efficiency:
The global efficiency ratio shall be above or
equal to 60% : Rg = (C+E)/Q ≥60%,
The thermal recovery ratio shall be above or
equal to 50% : Rr = C/E ≥50%,
For Installed powers < 3MW For Installed powers > 3MW
66% of produced electricity can be 50% of produced electricity can be
transferred to national grid transferred to national grid
E: Thermal Equivalent of produced electricity, C: Thermal & Effective energy recovered, Q: primary consumed energy
The decree 2773 dated in September 2009, allows the transport of Electricity from one point
to another one via the grid. In this framework TAV Tunisie is willing to send the excess of
Electricity produced to Monastir International Airport.TRIGENERATION PLANT
• Upon completion of the Airport construction works, a comparative analysis was
undertaken at the aim of reducing the power bill. The outcome was that Trigeneration
shows a higher profitability than the standard power solutions, with a satisfactorily
return on investment rate.
• On May 2012, TAV Tunisia started to operate its new 4 MW trigeneration power plant,
extendable to 6 MW. This new trigeneration plant, leader in Tunisia, enables the
simultaneous production of electricity, heating and cooling from natural gas.
• To this end, two gas engines, developing respectively, an electrical power of 2022 KW,
enable to cover the airport demand. The exhaust gas as well as the engines coolant will
be used for the production of heating in winter, and cooling via two lithium bromide
absorption chillers with a single capacity of 2000 KW to meet the air conditioning
demand on summer.
• The investment cost of this plant is around 10 million of dinars (5 M€).
16TRIGENERATION PLANT
• L'installation de Tri génération est composée de ;
• Deux moteurs à gaz de type Caterpillar développant une puissance nominale de
2 022 KW chacun,
• Deux échangeurs à plaques dont la puissance unitaire est de 995Kwth,
• Deux groupes d'eau glacée à absorption Type Broad de puissance frigorifique
2173Kwc et 994Kwth chacun.
• Cette installation devrait couvrir les besoins électriques et calorifiques de l’aéroport
ainsi qu’une grande partie des besoins frigorifiques.ENERGY PROFILE

and the excess of electricity produced is being sold the national provider of Electricity.

21Building Management System
BMS is used to simplify
and automate airport
systems :
• Lighting System
• Electronic System
• Mechanical System
• HVAC System
This kind of management
enables to operate the
system according to the
traffic needs resulting in
consistent energy savings
22CARBON FOOTPRINT
23GHG footprint
