Mastering construction
Building confidence

General contracting

GA Entreprise is GA’s general contracting company. Its area of expertise covers all phases from the design to the handover of a turn-key building.

GA Entreprise’s strength lies in the skill of its personnel, which includes a high percentage of engineers, and in its use of building processes that are optimized with every new building project. Developed by the group’s Research and Development department, these processes enable GA to design and construct buildings consistently and homogeneously. Our products and processes have been proven efficient; this is why, without incurring any significant additional cost, GA Entreprise’s buildings are always certified with the green building labels HQE® and BBC.

Our processes and equipment concern:

• Concrete structures
• Exterior aluminium joinery
• Architectural concrete façades
• Air handling via individual air-to-air heat pumps
• Centralized Technical Management: GAPEO®

Far from being a constraint, these systems are a genuine tool box for the project’s architect, in whose hands they become a way of combining architectural quality with intelligent design.

Arte Charpentier, Atelier 115, Anthony Béchu, Jean-Philippe le Covec, Jean-Paul Viguier and Aymeric Zublena are just a few of the well-known architects who have demonstrated their confidence in GA and have designed and built buildings in partnership with GA Entreprise.

For decades GA Entreprise has set the standard in commercial property. Now geared strongly towards the production of green office buildings with High Environmental Quality (HQE) certification, it has become a leader in office building production throughout France.

Equipment

GA, the specialist in commercial property, stands out from its competitors by its range of features that add comfort and security. Since the late 1980s GA has been ceaselessly designing, developing and improving the efficiency, in particular the energy efficiency, of heating, lighting and other apparatuses. Today GA’s comfort-enhancing equipment is grouped together under the trademark GAPEO^®. It encompasses:

• An air handling apparatus, the GA reverse-cycle S9 heat pump, which performs the functions of heating, cooling, dual-flow hygienic ventilation and free cooling, supplying just the right amount of energy required to meet the final user’s needs as closely as possible.
• Free-standing light fittings by Gadelune, equipped with electronic dimmers and detectors that adjust automatically depending on the amount of natural light available.
• The DB20061 window, equipped with triple glazing and integrated motorized blinds that improve both thermal and visual comfort
• A hardware key that allows users to remotely control all these devices
• Centralized Technical Management (CTM), which communicates with all the equipment in order to transmit information such as operating status and energy consumption to the monitoring station in real time
• A web site that communicates with the CTM, enabling authorized users to check their building’s detailed energy consumption, broken down by usage : HVAC , lighting, etc.

GAPEO^® gives building managers decision-making and coordination tools that reduce operating costs:

• Optimization of the power supply contract
• Automated management of technical facilities on a day-to-day basis, the ideal way to prevent any excess and guarantee lasting energy efficiency while providing the utmost in comfort

GAPEO^® is continually being upgraded, and this process of constant innovation enables the GA Group to meet the requirements of the energy certification (BBC 2005 Effinergie®) and the environmental labels (NF Bâtiments Tertiaires – Démarche HQE®). It also means that GA can formally commit itself to users to reducing energy consumption by signing agreements such as the Energy Performance Contract. This unique know-how makes GA a renowned player in commercial real estate and sustainable construction.
