The construction, intended for offices, is composed of two parallel buildings. The buildings are located in the direction of the slope of the ground, with access to the upper part of the land, giving directly onto an esplanade that allows access to the offices from the parking lots. A convivial space protected by a stretched canvas connects the two buildings to each other and allows the users to meet in the shelter of the sun and the rain, having a view on the magnificent landscape located below.
The building produces the energy needed to refresh it, its lighting and its operation by a field of photovoltaic panels which will also eventually charge electric vehicles.
The buildings are composed of 3 levels, including an R-1 level partially embedded in the natural ground.

Owner approach of sustainability
The EPFAG is a strong actor in the creation of Guyanese territory. From the very outset of his own headquarters, he decided to create the first bioclimatic energy-positive building in Guyana. In addition, the building is located at the Amazonian Factory, Guyana's first business plateau. It must therefore, by its strategic positioning, be exemplary in terms of building a tertiary building.
- Implementation of the building in the direction of the prevailing winds - fretted roof and large edges - solar protections on the facade, coupled with large windows allowing significant natural light inputs - insulation of walls and floors - use of local wood - installation of photovoltaic in superimposition in roof and wind - treatment of hygienic air for comfort of users in a humid climate - high-performance centralized air conditioning of the DRV type allowing in-air comfort, quiet operation and low consumption. - geographical location in the vicinity of commercial activities and residential areas, making it possible to limit the transport by car
If you had to do it again?
We would pay even more attention to the design phase in which many site hazards can be avoided. This phase must be longer to shorten the realization.
