Offices, retail units and commercial units
The Triologie building offers an exceptional combination of spaces dedicated to office, retail and artisanal activities in Luxembourg. If they so wish, tenants can have their show-room, offices and even a storage area together in a single location.
Triologie provides access to top-quality services – it does this to provide its users with everyday comfort but also to enable them to enjoy a better work-life balance.
Surpassing legal requirements
For the designers behind the Triologie project, it was supremely important to make best use of the spaces to optimise energy performance and comfort for the building’s users. Much thought was given to the use of renewable energy to provide for the building’s needs and to ways of reducing the remaining energy requirements. The ultimate aim is manifold and focuses particularly on ensuring that the facilities are sustainable and the tenants satisfied.
Using a geothermal manifold makes it possible to take advantage of the difference in temperature between the ambient air and the ground. Heat energy is exchanged with the liquid flowing through the coils by using a Turbocore type heat pump with very high efficiency, low energy consumption and a high performance coefficient.
The thermoactive slab is a floor structure into which coils are integrated – while the concrete is being poured they are very carefully positioned. The hot or cold water which flows through these coils can either warm or cool the concrete which, given its considerable inertia, gradually releases the stored energy.
The principle of free cooling involves cooling a building by using the difference in temperature between the air inside and outside. Cooling is achieved without using any cooling energy, as the building can be cooled using a cooling tower which extracts heat from the water by bringing it into contact with the air.
Office buildings tend to become warm, mostly because of internal but also external heat gains. External shading devices are fitted to exposed outer walls.
