The European Union-funded, UNDP implemented, ‘Renewable Energy for the Lebanese Armed Forces project’ focuses on strengthening the security and well-being of the Lebanese Armed Forces (LAF), specifically the LAF stationed in the North-Eastern border regions of Lebanon. The aim of the project is the provision of sustainable energy solutions that, first and foremost, increase the LAF’s energy autonomy in the region and enhance the general energy services that achieve a higher ability to observe and carry out the respective security-based operations. These actions build on the Lebanese Armed Forces Sustainable Energy Strategy of 2017 (EU-UNDP CEDRO 4, 2017), endorsed by the Ministry of Defense and the LAF.  

It is part of this project that a tender to undertake thermal building retrofits in 7 LAF locations in the Lebanese North Eastern borders was launched. The JV of EEG and ARM Engineering won the tender and completed the project between March and October 2021. The scope included the tasks as detailed hereafter: 

         1. Aluminum Works: Replacing existing windows by Low E Double Glazing with the below key details

• The used aluminum profile is Gxi which is a polyamide profile mounted on each central mullion profile that acts as a thermal shield.
• Glass fiber reinforced double polyamide strips cramped onto 2 aluminum profiles.
• ensure break on transoms (9mrn-wide break) and on side mullions (10mm-wide break).
• Double glazing low E.

          2. Roof waterproofing Works with the following details

• The membrane used is Betagum P with 4mm thickness
• Double layer of membrane installed
• Aluminum flashing  installed over parapets  in addition to PU mastic sealant 
• Thermal roof insulation was applied after the waterproofing in 2 facilities

      3. Stone coping Works 

   Remove existing coping and install new stone copings as per approved detail.

      4. Thermal insulation to walls

        Gypsum Board wall installation including the following details:

• Install the studs on the internal walls after checking the wall deviation in order to fix them accordingly
• Install the studs with wood around the windows as per drawings.
• The dimension between each stud is 40 cm.
• In between the studs, extruded polystyrene of 3 cm thickness was added.
• Finally, all were filled with gypsum board.

Internal Walls insulation 

     5. Steel doors 

• Installation of Steel thermal insulated doors
• Steel doors were prepared to receive a standard overhead door Closer and fitted with vision panels.
• Fire rating door CF30

       6. Painting

After cleaning the walls, and ensuring they are totally dried, sandpapers were used to dull any uneven surfaces 

Three coats of putty and three coats of paint were applied respectively.

Final painting phase 

Thermal imaging and various measurements were taken to document the improvement in the thermal efficiency of the buildings.

The activities were a clear showcase of the potential improvement of the thermal building performance through retrofitting existing facilities, specially in rural and high-altitude locations. 

The project was concluded with two capacity-building workshops given to the Lebanese Army technicians and engineers.
