Window technological wood in Guyana
Close to the Route de Montabo and the Zephyr Ring Road, both very popular, the Forest and Wood House of Guyana is a distant landmark. In order to exist as a major equipment, modeling of the ground in a vegetable base provides a light and natural pedestal to the building.
The varied volumes and various heights form a heterogeneous ensemble that meets the different needs of the program: The volume of the showroom and reception room presents an original shape with arched curves and curve oriented towards the center of the parcel. In addition to being a playful visual cue, this volume demonstrates the performance and the originality that can bring the whole wood industry Guyanaise. This volume, a place of sharing and meeting open to the public, is at the heart of the project.
Two other wooden partitions contain the Library, the Xylotheque (listing the woods of Guyana), research laboratories and offices of the wood industry. A mineral volume houses the mechanical testing workshops. This differentiation makes it possible to clearly identify the different functions of the project, while offering dynamic environments and varied views on the neighborhood.
A large roof "canopy", organic form, calms this heterogeneity by sheltering and unifying the various buildings under its canopy. The fusion between the plant and the mineral occurs naturally.
The project affirms its balance by the great vertical breakthrough, hollow "tree stump". It creates a well of filtered light on the project and erects a flagship signal in the extension of the landscaping of the Hibiscus ZAC.
This strong architectural part, integrated in the district, preserves thermal comfort. Volumetry meets the climatic requirements (protection of facades, natural ventilation, sun protection, optimization of air conditioning) by limiting the effects of mask for the surrounding buildings.
The choice of the use of peyi wood as the main material is evident when it comes to building the premises of the promoter of the wood industry in Guyana. Its use has been reflected both in terms of an architectural requirement and of good management of natural resources.
Sustainable development approach of the project owner
The objective was to define, in terms of the mass plan, the Bioclimatic compromise on the basis of the following provisions: - Implement the building according to the strengths and constraints of the site: orientation, sunshine, Noises, winds, quality of outdoor spaces, shores, etc. - For other areas with high internal inputs (offices, cloakrooms, wellness areas, etc.), The most favorable orientations, those which provide the maximum amount of natural light Minimum solar overheating and minimal thermal losses. - To preserve the right to the sight, the light, the sun and the calm of the local residents, with Particular for residential areas. Concerning the envelope and the volumetry of the building, the objective is to define the best bioclimatic compromise on the basis of the following provisions: - Optimize glazed surfaces (size, leakage coefficient, solar factor) in order to Solar radiation and a satisfactory level of natural lighting while limiting the loss and overheating. - Limit unnecessary heights / volumes and isolate the envelope strongly to limit its losses thermal. - Encourage constructive typologies of building envelope and volumetric Natural through ventilation. - Install sun protection on exposed façades. - Ensure the conditions of comfort, through passive technical and constructive solutions (orientations, Solar radiation, solar protection, inertia, ventilation, natural lighting, insulation) so as not to The use of energy-intensive systems (lighting, refreshment, artificial lighting) Than as a complement.Architectural description

More information
Consumption has been estimated in the design phase, the actual consumption can be determined after one year of operation. nb. The use of the RT2012 calculation standard for this project in the Guyanese context required the following adaptations: climatic zone H3, offices use, summer comfort CE2, climatic data, standardized hours. The reference values are: CEP max = 132 kWhEP / m² / year. The Electricity -> Primary Energy conversion factor is estimated at 2 for the coastal Guyana electricity grid.

Use of local wood on all roofs of the project, the central totem. The exhibition room is made up of 100% local wood (superstructure, roofing, flooring ...).
It was a clear objective of the project manager: The building, which welcomed the local wood industry, had to be a demonstration of local know-how in the field.
