Rehabilitation of the building of the headquarters of the Urbanism and Development Agency of Guyana (AUDEG)

This project has two main objectives:

1- Review the interior distribution of the building to increase the surface area of the Audeg offices by recovering the now empty rental spaces.

2- Improve the thermal protection of the building and the efficiency of the equipment in order to limit the electricity consumption.

Concerning the interior distribution, openings were created between offices and circulations in order to offer transparencies and perspectives on the different spaces.

Sustainable development approach of the project owner

Approach "Environmental Quality Amazonian" (Ademe Guyana)

An energy diagnostic financed by Ademe and carried out by Ingeko has shown the weakness of the building and make improvements to ensure good thermal protection.

Architectural description

Originally, the building was already exemplary in the use of local materials (bricks fired on the front wall and wooden shingles on the roof and awning, and it also had numerous openings in the façades and its plan allowed for through spaces.

The project focused on the envelope to improve solar protection and insulation, and on indoor distribution. The awning in damaged shingle was replaced by a broad horizontal sun breeze. Insulation was installed in the attic. The joinery has been replaced by more watertight ones with antelio glazing. At the indoor level, high-performance electrical equipment has replaced the old ones, with efficient air-conditioning and air brewers. Glazed windows between offices and circulations have been created to increase the impression of space and to open up perspectives. on the outside.

Building users opinion

The occupants are very satisfied with the rehabilitation which has brought them more comfort at the same time thermal but also acoustic and visual

If you had to do it again?

The energetic renovation being a major stake for the fight against global warming, these projects are indispensable and must be multiplied.

Reasons for participating in the competition(s)

La protection thermique a été améliorée grâce à la rénovation des façades et leur modification (remplacement de l’auvent en bardeau de Wapa par un brise soleil en aluminium, déplacement et protection des climatiseurs par une résille en bois local, remplacement des fenêtres par des vitrages antelio, ajout d'un auvent en tôle à l'étage du pignon à l’ouest, ajout d'un pare-soleil vertical en bois local sur l'entrée). De plus une isolation a été posée sous les plancher bois afin d’assurer un meilleur confort thermique et acoustique. Des climatiseurs A++ ont remplacé les anciens appareils moins efficaces et des brasseurs d’air ont été installé dans tous les bureaux afin de permettre une réversibilité des locaux.
