    Rustic tile colors Mesnil

    Terreal

  • Structural work / Carpentry, cover, titghtness
  • In addition to its thickness and its robustness, Rustic tile TERREAL owns a Solar Reflectance Index pupil (IRS = 31) answering all the requirements of LEED Platinum repos. The IRS is an index to estimate the solar radiation that is reflected by the tile. If the tile retransmits much of the received solar radiation, the amount of heat transmitted to the interior of the building will be limited. According to the same logic, the surface temperature of the roof will also be less high.From a more technical point of view, the comfort of summer is taken into account through the Solar Factor (S). Given its dependence to the reflectance of the wall and its insulation, it will imperatively increase the IRS and thermal insulation (R) to ensure true comfort summer.

    Enter the LEED framework, also demonstrate that the french players, Ile 100% in this case, have a know-how which can be exported to the international despite the specificities of the French regulation. This choice of material has been approved by the Architect of Buildings of France Ile de France.

  • HVAC, électricité / heating, hot water
  • Equipped with heated floors, refreshing the ground floor and upstairs, with some space heaters, the media library gets most of its energy from a geothermal drilling is under a parking lot, a few meters of the building. 49 meters deep, the water has a drilling recovered 12-13 ° C which is then reintroduced into the water by means of two reinjection wells. In the meantime geothermal energy is recovered by a heat pump reversible Climasol Wavin a heat output of 40kW (coeff. power: about 4). The heat pump supplies all the heat and battery of the central air handling double-flow diffusers.

  • HVAC, électricité / ventilation, cooling
  • Central air handling a rotary heat exchangerCTA - complete with a direct drive fans blowing and extraction filters blowing and extraction and rotary heat exchanger.- The thermal efficiency, heat recovery up to 85%.- Air flow up to 50,400 m³ / h.- Regulation of variable rotor speed.- Recuperation of energy coolingTwo new sizes (7 and 11) and a fan optimizes offer more freedom to choose exactly the unit size and model of fan adapted to the needs of the installation. And therefore, even more opportunites to optimize the energy performance of the project.The most striking novelty is the revolutionary system of regulation, IQlogic. Besides many intelligent and user-friendly functions, much more powerful options are proposed for communication and remote control from a main control system, a laptop, a tablet or a mobile phone. This regulation system can be equipped with additional modules to increase the functions.All GOLD units have the characteristics and advantages of GOLD unique concept: work simplification and guarantee reliable performance.The GOLD are for ventilation comfort.- Depending on the version selected, GOLD units can bebe built in office buildings, schools, nurseries, public buildings, shops, residential buildings, etc..- EC technology for all sizes- Integrated control system for greater simplicity of installation- Full range of accessories optimized for GOLD global optimization performance and time saving installation- Eurovent Certification with guaranteed data- All units are tested before delivery - reliability is guaranteed!High efficiency energetics and efficient heat recovery of the GOLD RX (04-35 sizes, and 50) were Certified Passive House. This makes it unique in the world GOLD, becoming the first CTA to students air flow rates (<9000 m³ / h) that meets the requirements of the Passive House certification.Rotary heat exchanger RECOnomic- Rotating aluminum wheel having a plurality of small gaps- Systems of extremely efficient heat recovery, with ever higher performance 80%

    Thanks to the central processing air, mediatheque recovered nearly 80% of energy
