Owner approach of sustainability
The principle of design and construction approach respects the Moroccan thermal regulation and allows one hand to demonstrate the reproducibility on a large scale (individual houses) on the other. the principle of purchase and information system of the house DEFI allows both the experience feedback on the building behavior and the adoption of best practices by occupants
The "CHALLENGE" platform is a reinforced concrete building in accordance with Moroccan seismic rules. Different architectural consideration were taken into account to improve Energy efficiency CHALLENGE: 1- Orientation South East: to enjoy sunshine Winter and avoid morning overheating was 2- Lack of openness on the facade West (Avoid overheating summer morning and enjoy the temperature rise to less over-ventilation) on level ground floor 3- (Continuous insulation and inertia) 4 - Roof Painting board (gains reduce radiation in summer) 5 - compactness with a central corridor (Gain energy and ventilation efficiency) 6- Openings reduced> 20% of the thermal envelope 7 Double room (North - South) was dual use - Winter.

Heat pump: T.One
T.ONE is an individual heating solution for any type of habitat that also ensures the refreshment in summer. This system implements a heat pump air / air coupled to a distribution plenum and motorized vents. Exclusive Aldes, the system loads a T.One room control for better management of comfort and saving more, adjusting the power of the heat pump and blown air flow. In addition to its exceptionally low consumption, this solution is characterized by its low noise level. T.ONE range of products consist of an indoor unit and an outdoor unit associated with regulation and a complete range of ventilation accessories.
Double Glazing Argon Filling

A reinforced insulation glazing (VIR) has a treatment that is opposed to infrared radiation and forms a thermal barrier, without constituting an excessive obstacle to visible light. A VIR therefore prevents the heat from escaping in winter and return in the summer.

The ground-air heat exchanger is used to supply air in a building by circulating in a pipe buried before that depending on the weather cooled or preheated by using the thermal inertia of the soil. The air serves as coolant while the tube serves as a heat exchanger while channeling the air to the building. The Provençal well, although mainly used as natural cooling system may also be used in winter to preheat the incoming air or to maintain a dwelling frost. It is the same Canadian wells.
Laboratoire Génie Civil et Bâtiment (ENTPE-LYON)
The Air-exchanger Materials Phase change is used to heat the building in winter, it will be coupled with a solar chimney. A summer release is outstanding experimentation.
MATLAB ("matrix laboratory") is a fourth-generation programming language emulated by the same name development environment; it is used for numerical calculation. Developed by The MathWorks, MATLAB can manipulate matrices, display of curves and data, implementation of algorithms, creation of user interfaces, and can interface with other languages like C, C ++, Java, and Fortran. MATLAB users (about one million in 20041) are very different backgrounds such as engineering, science and the economy in a context as well as for industrial research. Matlab can be used alone or with toolbox ("Toolbox").
LabVIEW (Laboratory Virtual Instrument contraction Engineering Workbench) is the heart of a platform measuring system design and control, based on National Instruments graphical development environment. The graphic language used in this platform is called "G". Originally created on Apple Macintosh in 1986, LabVIEW is used primarily for measurement data acquisition to instrument control and industrial automation. The platform development is running under different operating systems like Microsoft Windows, Linux and Mac OS X can generate LabVIEW code on these operating systems but also on real-time platforms, embedded systems or FPGA reprogrammable components. The latest version of LabVIEW was released in August 2013.
