The city of Bizerte conducted an energy audit on plans relating to the new annexe to be built for city hall. The audit, assisted by Clip software, pointed toward an action plan based on a scientific approach that would reduce energy use throughout the entire new building by 30%, i.e. 11.23 toe/year. The gross payback period was 5 years for the 5 actions put forward by the audit, namely :

• Improvement to the energy efficiency of glazed openings : use of double glazing
• Use of insulations on roof terraces
• Use of insulation in external walls
• Substitution of LED lights for classic bulbs to reduce the installed lighting power
•  Improvement to the air conditioning system

There was a sixth action on energy production by renewable sources through the installation of a photovoltaic facility to make the building autonomous.

Expected results:

• Improvement to energy performance
• Reduction of energy bills
• Improvement to thermal comfort
• Contribution to the energy transition
• Improvement to the energy categorisation
• Reinforcement of the environmentally sustainable building policy in the city of Bizerte

• Building energy category improved
• Thermal comfort improved
• Thermal regulation applied
• Building constructed at 70%
• Carbon emissions reduced (22 tonnes of CO₂ equivalent)
• Model building for environmentally sustainable construction
• Energy-autonomous building through use of renewable energy (photovoltaic)
