Primary energy need
(Calculation method : RT 2012 )
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.
Sustainable development approach of the project ownerThe 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.
Architectural description- 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
Building users opinion
Pride in working in a building that produces more energy than it consumes
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.

Type of market
Global performance contract
- 114,00 kWhep/m2.an
- 400,00 kWhep/m2.an
Real final energy consumption
- 1,70 W.m-2.K-1
The actual consumption is measured by the GTB system, distinguishing the different zones and uses (air conditioning, lighting, other uses, production). The data will be used for feedback after a full year of use of the building. The use of the RT2012 calculation standard for this project in the Guyanese context required the following adaptations: climatic zone H3, office use, summer comfort CE2, climatic data standard hours. The reference values are: CEP max: 132 kWhEP / m² / year CEP BEPOS: 79 kWhEP / m² / an Bbio max: 168
