Description

Title of the invention: Method for managing the ventilation of at least a first zone of a building

[0001] The present invention relates to a method for managing the ventilation of at least one zone of a building. The invention also relates to a device adapted to implement this management method.

[0002] During periods of heat, natural ventilation of a building by opening windows at night is one of the most effective ways to cool it down. The ideal time to begin nighttime cooling starts when the outside temperature becomes lower than the inside temperature.

[0003] When the openings are not motorized, a building occupant must therefore be responsible for opening the windows at the appropriate times. This is not always possible if these times (which may vary depending on the building's purpose and location) fall during a period when the occupants are asleep or when the building is unoccupied (particularly for industrial and commercial buildings).

[0004] During heat waves, the ideal times to cool a building at night by opening windows and possibly opening / closing blinds frequently coincide with periods when the occupants are asleep or when the building is unoccupied. It is therefore not always easy for the occupants to know: - whether it is better to open windows and possibly the blackout blinds just before going to bed (or leaving the building), or - whether it is better to keep the openings closed and maintain the blackout device closed all night (or for the entire period when the building is unoccupied), or - in the case of motorized shading devices, if it is appropriate to leave an automatic system activated, this system can control the shading device automatically according to different criteria.

[0005] The present invention aims to overcome the aforementioned drawbacks and to provide a method for managing the ventilation of at least one zone of a building, as well as a device adapted to implement this management method. In particular, the invention proposes a method for improving thermal comfort and minimizing energy consumption in a building.

[0006] According to the invention, the method makes it possible to manage the ventilation of at least a first zone of a building equipped with an opening by: - configuration of at least one first manually operated opening, equipping the opening of at least one first zone, and - Optionally, configuration of an operating mode for an electromechanical device to block the opening of at least one first zone. The process includes the following steps: - detection of an event or a time, - simulation of a temperature evolution in at least one first zone of the building during a specified future period in the assumption of a ventilation situation linked to an opening of the first opening and possibly of the electromechanical shading device and of a temperature evolution in at least one first zone of the building during the specified future period in the assumption of a situation of absence of ventilation linked to a closing of the first opening and possibly of the electromechanical shading device, - communication of the simulations to a user and / or issuance, to the user, of a recommendation to ventilate, by opening the first opening and possibly of the electromechanical shading device, or not to ventilate, by closing the first opening and possibly of the electromechanical shading device, the at least one first zone during the specified future period.

[0007] The method may include a step of defining at least one time range during which the user cannot operate at least one first opening.

[0008] The method may include a step of motorized operation control of a screen equipping at least one opening.

[0009] Preferably, during the specified period: - the screen is open when the outside temperature of the building is lower than a temperature in at least one first zone, and - the screen is closed when an outside temperature of the building is higher than a temperature in at least one first zone or when a temperature in at least one first zone is lower than a first threshold.

[0010] Each simulation may include: - determining an estimate of the time at which the outside temperature of the building is equal to the temperature in at least one first zone, and / or - determining an estimate of the temperature in at least one first zone at the end of a specified period in the future, and / or - determining an estimate of the duration during which a temperature in at least one first zone is below a first threshold.

[0011] The recommendation to ventilate or not to ventilate may be issued: - continuously for the specified period, or - upon request, in particular upon request from the user, or - at regular time intervals during the specified period, or - each time the configuration should be changed during the specified period.

[0012] Each simulation may include a calculation of a comfort index, in particular based on the duration of exceedances of thresholds by the temperature of at least a first zone during the determined period.

[0013] The process may further include the following steps: - simulation of temperature evolution in a second zone of the building during the specified upcoming period under the assumption of ventilation, and of temperature evolution in the second zone of the building during the specified upcoming period under the assumption of no ventilation. - communication of simulations to a user and / or issuing, to the attention of a user, a recommendation to ventilate or not ventilate the second zone during the specified period to come.

[0014] According to the invention, a device, in particular a mobile terminal, comprises hardware and / or software elements configured to implement the management process defined above.

[0015] According to the invention, an installation comprises: - a means of determining the evolution of the outside temperature of the building over the next few hours, particularly during the coming night, and - at least one thermometer allowing one or more temperatures to be known inside the building.

[0016] According to the invention, a computer program product comprises program code instructions recorded on a computer-readable medium to implement the steps of the process defined above when said program runs on a computer.

[0017] According to the invention, a computer program downloadable from a communication network and / or recorded on a data medium readable by a computer and / or executable by a computer is characterized in that it includes instructions which, when the program is executed by the computer, lead the latter to implement the process defined above.

[0018] The present invention further relates to: - on a computer-readable data recording medium on which is recorded a computer program comprising program code instructions for implementing the process defined above, or - on a computer-readable recording medium comprising instructions which, when executed by a computer, cause the computer to carry out the process defined above.

[0019] The invention further relates to a signal from a data carrier, carrying the computer program product defined previously.

[0021] First, with reference to Figures 1 and 2, a blackout installation 100 is described. This blackout installation 100 comprises a building B, at least one window 40 and at least one blackout device 3.

[0022] Building B includes at least one wall W. Wall W includes at least one opening 1.

[0023] Window 40 is housed inside opening 1 in wall W.

[0024] Advantageously, the window 40 comprises at least one fixed frame 41 and at least a pane of glass 42. The pane of glass 42 is arranged inside the fixed frame 41, in particular in an assembled configuration of the window 40.

[0025] Advantageously, the window 40 may, in addition, include at least one opening 401.

[0026] Advantageously, the glass 42 can be either mounted in the fixed frame 41, in the case where it is fixed relative to the fixed frame 41, or mounted in a frame of the opening 401, in the case where it is mobile relative to the fixed frame 41, in particular according to a rotational movement, especially in the case of a tilting or casement window, or according to a translational movement, especially in the case of a sliding window in a horizontal or vertical direction, or according to two rotational movements, especially in the case of a tilt-and-turn window.

[0027] The shading device 3 comprises a screen 2, in particular a roller shutter. The screen 2 of the shading device 3 serves to more or less obscure the opening 1.

[0028] Advantageously, the blackout device 3 further comprises a housing 9.

[0029] The blackout device 3 may be a roller shutter, a fabric blind, or with Adjustable slats, a rolling gate, a grille, or even a door. The present invention applies to all types of shading devices.

[0030] The screen 2 is configured to be positioned opposite the window 40, so as to partially or completely block the opening 1 in the wall W. In principle, the blocking provided by the screen is not as airtight as that provided by a window. Thus, when the window 4 is open and the screen 2 is lowered, some ventilation of the building can occur.

[0031] A shutter installation and a sun protection installation are examples of shading installations. Similarly, a shutter device and a sun protection device are examples of shading devices.

[0032] The installation for closing, shading or sun protection is hereafter referred to as "shading installation" 100.

[0033] The closing, shading or sun protection device is hereafter referred to as a "shading device" or "electromechanical shading device" 3.

[0034] An electromechanical occulting device usable in an embodiment of the invention is described with reference to figures 1 and 2.

[0035] The electromechanical occulting device 3 includes a motorized drive device 5. The motorized drive device 5 includes an electromechanical actuator 11 illustrated in [Fig.3].

[0036] Advantageously, the electromechanical blackout device 3 further comprises a winding tube 4. The screen 2 is windable onto the winding tube 4. In addition, the winding tube 4 is arranged so as to be driven in rotation by the electromechanical actuator 11.

[0037] Thus, the screen 2 of the electromechanical occulting device 3 is wound on the winding tube 4 or unwound around it, the winding tube 4 being driven by the motorized drive device 5, in particular by the electromechanical actuator 11.

[0038] In this way, the screen 2 is mobile between a rolled-up position, in particular high, and an unrolled position, in particular low, and vice versa.

[0039] The screen 2 of the electromechanical shading device 3 is a closing, shading and / or solar protection screen, rolling and unrolling around the winding tube 4, the inner diameter of which is greater than the outer diameter of the electromechanical actuator 11, so that the electromechanical actuator 11 can be inserted into the winding tube 4, when assembling the electromechanical shading device 3.

[0040] The electromechanical actuator 11, in particular of tubular type, allows the winding tube 4 to be rotated around an axis of rotation X, so as to move, in particular unwind or wind up, the screen 2 of the electromechanical occulting device 3.

[0041] In an assembled state of the electromechanical occulting device 3, the electromechanical actuator 11 is inserted into the winding tube 4.

[0042] In a known manner, the roller shutter, which forms the electromechanical blackout device 3, comprises a curtain including horizontal slats hinged to one another, forming the screen 2 of the roller shutter 3, and guided by two lateral tracks 6, shown only in [Fig.2]. These slats are joined when the curtain 2 of the roller shutter 3 reaches its fully extended lower position.

[0043] In the case of a roller shutter, the raised, fully wound position corresponds to the bearing of an end slat 8, for example L-shaped, of the curtain 2 of the roller shutter 3 against an edge of a housing 9 of the roller shutter 3, or to the stopping of the end slat 8 in a programmed upper limit position. Furthermore, the lower, fully wound position corresponds to the bearing of the end slat 8 of the curtain 2 of the roller shutter 3 against a threshold 7 of the opening 1, or to the stopping of the end slat 8 in a programmed lower limit position.

[0044] Here, the screen 2 is configured to be moved, by means of the motorized drive device 5, in particular the electromechanical actuator 11, between an open position, corresponding to the wound-up position and which can also be called the first end-of-stroke position or upper end-of-stroke position FdCH, and a closed position, corresponding to the unwound position and which can also be called the second end-of-stroke position or lower end-of-stroke position FdCB.

[0045] Thus, the electromechanical actuator 11 is configured to drive, in other words drives, in movement the screen 2, between the first end position FdCH and the second end position FdCB, and vice versa, opposite the window 40, in particular the glass 42.

[0046] Here, screen 2 is positioned outside the building.

[0047] The first slat of the roller shutter 3, opposite the final end slat 8, is connected to the winding tube 4 by means of at least one joint 10, in particular a band-shaped attachment piece.

[0048] The winding tube 4 is arranged inside the box 9 of the roller shutter 3. The curtain 2 of the roller shutter 3 winds and unwinds around the winding tube 4 and is housed at least partly inside the box 9.

[0049] Generally, the chest 9 is positioned above the opening 1, or in the upper part of the opening 1.

[0052] Advantageously, the central control unit 13 can control the local control unit 12, as well as other similar local control units distributed throughout building B.

[0053] The motorized drive device 5 is preferably configured to execute the commands for unwinding or rewinding the screen 2 of the electromechanical blackout device 3, which can be issued, in particular, by the local control unit 12 or the central control unit 13.

[0054] The blackout installation 100 comprises either the local control unit 12, or the central control unit 13, or the local control unit 12 and the central control unit 13.

[0055] An automatic control system for the electromechanical shading device 3 can be included in a local control unit 12 or a central control unit 13 and control the motorized drive device, for example, based on environmental conditions such as temperature, humidity, and time. The automatic control system can be activated or deactivated; in the latter case, it no longer automatically controls the motorized drive device.

[0056] Alternatively, the shading device is operated manually. In this case, the structure is substantially identical to the above description except for the motorized drive device.

[0057] The motorized drive device 5, including the electromechanical actuator 11, belonging to the blackout installation 100 and, more particularly, to the electromechanical blackout device 3 illustrated in Figures 1 and 2, is now described in more detail with reference to [Fig.3].

[0058] The electromechanical actuator 11 comprises at least one electric motor 16.

[0059] The electric motor 16 is represented by its casing in [Fig.3], without details on its internal constituent elements.

[0060] Advantageously, the electric motor 16 comprises a rotor and a stator, not shown, positioned coaxially around the axis of rotation X, which is also the axis of rotation of the winding tube 4 in the mounted configuration of the motorized drive device 5.

[0061] Here, the electric motor 16 can be of the electronically commutated brushless type, also called "BLDC" (acronym for the Anglo-Saxon term BrushLess Direct Current) or "permanent magnet synchronous", or of the direct current type.

[0062] Control means for the electromechanical actuator 11, enabling the movement of the screen 2 of the electromechanical occulting device 3, include at least one electronic control unit 15. This electronic control unit 15 is capable of activating the electric motor 16 of the electromechanical actuator 11 and, in particular, enabling the supply of electrical energy to the electric motor 16.

The local control unit 12 and / or the central control unit 13 is equipped with a control keypad. The control keypad of the local control unit 12 or the central control unit 13 includes one or more selection elements 14 and, optionally, one or more display elements 34.

[0073] By way of non-limiting examples, the selection elements may include pushbuttons and / or touch-sensitive keys. The display elements may include light-emitting diodes and / or a display, for example LCD (Liquid Crystal Display) or TFT (Thin Film Transistor). The selection and display elements may also be implemented using a touchscreen.

[0074] Advantageously, the local control unit 12 and / or the central control unit 13 includes at least a second communication module 36.

[0075] Thus, the second communication module 36 of the local control unit 12 or of the central control unit 13 is configured to transmit, in other words, sends out, control orders, in particular by wireless means, for example radioelectric, or by wired means.

[0076] In addition, the second communication module 36 of the local control unit 12 or of the central control unit 13 can also be configured to receive, in other words receives, control orders, in particular through the same means.

[0078] Thus, the second communication module 36 of the local control unit 12 or of the central control unit 13 exchanges control orders with the first communication module 27 of the electronic control unit 15, either unidirectionally or bidirectionally.

[0079] Advantageously, the local control unit 12 is a control point, which can be fixed or mobile. A fixed control point can be a control box intended to be fixed to one face of the wall W of building B or to one face of the Fixed frame 41 of the window 40 or a door. A mobile control point can be a remote control, a smartphone or a tablet.

[0081] The motorized drive device 5, in particular the electronic control unit 15, is preferably configured to execute movement control commands, in particular closing and opening, of the screen 2 of the electromechanical occulting device 3. These control commands can be issued, in particular, by the local control unit 12 or by the central control unit 13.

[0082] The motorized drive device 5 can be controlled by the user, for example by receiving a command order corresponding to a press on the or one of the selection elements 14 of the local control unit 12 or of the central control unit 13.

[0083] The motorized drive device 5 can also be controlled automatically, by automation, for example by receiving a control command corresponding to at least one signal from at least one sensor 44 and / or a signal from a clock, not shown, of the electronic control unit 15, in particular the microcontroller 31.

[0085] The housing 17 is hollow. The housing 17 comprises a first end 17a and a second end 17b. The second end 17b is opposite the first end 17a.

[0086] Here, the housing 17 of the electromechanical actuator 11 is cylindrical in shape, in particular of revolution around the axis of rotation X, and is open at each of its ends 17a, 17b.

[0087] Advantageously, the housing 17 is a tube having a circular cross-section.

[0088] In one embodiment, the housing 17 is made of a metallic material.

[0089] The material of the electromechanical actuator housing is not limiting and may be different. It could be, in particular, a plastic material.

In such a case, the ring 30 can be mounted freely in rotation, on the one hand, around the torque support 21 and, on the other hand, around the housing 17.

[0121] Advantageously, the electronic control unit 15 is supplied with electrical energy by means of an electrical power cable 18.

[0122] Here and as illustrated in [Fig.3], the electronic control unit 15 is thus arranged, in other words is integrated, inside the housing 17 of the electromechanical actuator 11.

[0123] In an alternative, not shown, the electronic control unit 15 is located outside the housing 17 of the electromechanical actuator 11 and, in particular, mounted on the box 9 or in the torque support 21.

[0124] Advantageously, the torque support 21 may include at least one button, not shown.

[0125] This or these buttons can allow adjustment of the electromechanical actuator 11 through one or more configuration modes, pairing with the electromechanical actuator 11 one or more control units 12, 13, resetting one or more parameters, such as, for example, a limit position, resetting the paired control unit(s) 12, 13 or controlling the movement of the screen 2.

[0126] Advantageously, the torque support 21 may include at least one display device, not shown, so as to allow a visual indication of an operating parameter of the motorized drive device 5.

[0127] Advantageously, the display device includes at least one light source, not shown, in particular a light-emitting diode.

[0128] This or these light sources are mounted on an electronic board of the electronic control unit 15 and, optionally, a transparent or translucent cover and / or a light guide is or are provided, to allow the passage of the light emitted by the or each of the light sources.

[0129] Advantageously, the output shaft 20 of the electromechanical actuator 11 is disposed inside the winding tube 4 and at least partly outside the housing 17 of the electromechanical actuator 11.

[0130] Here, one end of the output shaft 20 protrudes from the housing 17 of the electromechanical actuator 11, in particular from the second end 17b of the housing 17.

[0131] Advantageously, the output shaft 20 of the electromechanical actuator 11 is configured to drive in rotation, in other words drives in rotation, a linking element 22. This linking element 22 is connected to the winding tube 4, in particular in the assembled configuration of the electromechanical occulting device 3. The linking element is, in the example of the figures, made in the form of a wheel.

[0132] When the electromechanical actuator 11 is switched on, the electric motor 16 and the reducer 19 drive the output shaft 20 in rotation. In addition, the output shaft 20 of the electromechanical actuator 11 drives the winding tube 4 in rotation via the connecting element 22.

[0133] Thus, the winding tube 4 causes the screen 2 of the electromechanical occulting device 3 to rotate, so as to open or close the opening 1.

[0134] The electromechanical obscuring device 3 and, more particularly, the motorized drive device 5 further comprises an electrical power supply device 26, visible in [Fig. 2]. The electromechanical actuator 11 is electrically connected to the electrical power supply device 26.

[0135] The electrical power supply device 26 includes at least one rechargeable battery 24.

[0136] The electrical power supply device 26 is configured to supply, in other words supplies, electrical power to the electromechanical actuator 11 and, more particularly, to the electronic control unit 15 and the electric motor 16.

[0137] Thus, the electrical power supply device 26 makes it possible to supply electrical power to the electromechanical actuator 11, without itself being electrically connected to a mains power supply network.

[0138] Advantageously, the electrical power supply device 26 further comprises at least one photovoltaic panel 25.

[0139] The electromechanical actuator 11 is electrically connected to the electrical power supply device 26 and, more particularly, to the photovoltaic panel 25, in particular by means of the electrical power supply cable 18. In addition, the battery 24 is electrically connected to the electronic control unit 15, by an electrical link L24-15, which may be an integral part of the electrical power supply cable 18.

[0140] Advantageously, the battery 24 is configured to supply, in other words provides, electrical energy to the electromechanical actuator 11, in particular the electronic control unit 15 and the electric motor 16.

[0141] Advantageously, in the case where the electrical power supply device 26 includes the photovoltaic panel 25, the battery 24 is configured to be powered, in other words is supplied, with electrical energy by the photovoltaic panel 25.

[0142] Thus, the charging of the battery 24 is carried out by solar energy, by means of the photovoltaic panel 25.

[0143] Here and as illustrated in [Fig.2], battery 24 is arranged inside chest 9, in particular directly inside chest 9.

[0144] Alternatively, not shown, the battery 24 can be arranged inside the winding tube 4 while being outside the housing 17, or inside the housing 17, particularly in the assembled configuration of the electromechanical actuator 11. In the latter case, the electromechanical actuator 11 includes the battery 24. In both cases, the battery 24 is also arranged inside the housing 9, since the winding tube 4 and the electromechanical actuator 11 are arranged inside the housing 9.

[0145] In another variant, not shown, the battery 24 is disposed outside the housing 9 and, more particularly, in a housing, not shown, which is disposed outside the housing 9. The housing can be made, in particular, in the form of a shell adapted to the geometric shapes of the battery 24, or in the form of a profile including a housing for receiving the battery 24. Advantageously, this housing can support the photovoltaic panel 25.

[0146] When the torque support 21 includes a display device, the operating parameter that this display device allows to be viewed is advantageously a state of charge of the battery 24.

[0147] Here, the electromechanical actuator 11 includes the power supply cable 18 enabling its supply of electrical energy, in particular the power supply of the electronic control unit 15 and the power supply of the electric motor 16, in particular from the battery 24.

[0148] Advantageously, the battery 24 comprises a plurality of energy storage elements 32, in particular electrically connected in series. The energy storage elements 32 of the battery 24 may be, in particular, rechargeable batteries.

[0149] Advantageously, the photovoltaic panel 25 comprises a plurality of cells photovoltaics 43. In this case, the battery 24 is supplied with electrical energy by means of the photovoltaic cells 43 of the photovoltaic panel 25.

[0150] Advantageously, the motorized drive device 5, in particular the photovoltaic panel 25 and / or the electronic control unit 15, includes charging elements configured to charge the battery 24, from the solar energy recovered by the photovoltaic panel 25. In this case, the current flows between the components 25, 24 and 15 through a wired connection, which may be separate from the electrical power supply cable 18.

[0151] Thus, the charging elements configured to charge the battery 24, from solar energy, make it possible to convert the solar energy recovered by the photovoltaic panel 25 into electrical energy.

[0152] Alternatively or in addition, the motorized drive device 5, in particular the electromechanical actuator 11, is supplied with electrical energy from the battery 24, from an auxiliary battery, not shown, or from a mains power supply network, in particular from the commercial AC network, in particular depending on a state of charge of the battery 24.

[0153] Here, the electronic control unit 15 comprises a single electronic board, not shown. Furthermore, the electronic board is configured to control the electric motor 16, to enable the charging of the battery 24 and, optionally, to access parameterization and / or configuration functions of the electromechanical actuator. 11, by means of selection and, possibly, display elements, not shown. As mentioned above, the battery charging elements 24 can be arranged on the electronic board.

[0154] In an alternative configuration, not shown, the electronic control unit 15 comprises a first electronic board and a second electronic board. The first electronic board is configured to control the electric motor 16. Furthermore, the second electronic board is configured to allow charging of the battery 24 and / or access to parameterization and / or configuration functions of the electromechanical actuator 11, by means of selection and, optionally, display elements, not shown. The battery charging elements 24 may be located on the second electronic board.

[0155] In the case where the electronic control unit 15 comprises a first electronic board and a second electronic board, not shown, the first electronic board of the electronic control unit 15 may be arranged inside the housing 17 of the electromechanical actuator 11. Furthermore, the second electronic board may be arranged inside the torque support 21 of the electromechanical actuator 11. Moreover, the torque support 21 may include a cover, not shown. In addition, the second electronic board may be arranged inside a housing formed between a portion of the torque support 21 and the cover.

[0156] Advantageously, the photovoltaic panel 25 can be fixed on the box 9, on the wall W of the building B, on one of the side rails 6, on the glass 42 of the window 40 or on the fixed frame 41 of the window 40.

[0157] The blackout installation 100 further includes at least one device 33, in particular a mobile terminal 33.

[0158] Here, the mobile terminal 33 can be the local control unit 12 and include all or part of the elements constituting it.

[0159] Preferably, the mobile terminal 33 is a smart phone, also called a "Smartphone" in English.

[0160] Alternatively, the mobile terminal 33 can be a touch tablet or a configuration tool.

[0161] The mobile terminal 33 can thus be any mobile device configured to implement a method for determining an operating state of the motorized drive device 5, as described below.

[0162] Advantageously, the mobile terminal 33 includes at least the controller 35.

[0163] Here, the mobile terminal 33 includes the second communication module 36, as previously described with reference to the local control unit 12, as well as the selection elements 14 and display elements 34.

[0164] The mobile terminal 33 or the cloaking device 100 includes all the hardware and software elements necessary for implementing the management method that is the subject of the invention, as described below. The elements may include software modules.

[0165] The installation includes, for example - a means of determining 98 the evolution of the outside temperature of the building over the next few hours, in particular during the coming night, this means of determination being, for example, a module for retrieving the evolution of the outside temperature of the building over the next few hours, in particular during the coming night, and - at least one 99 thermometer allowing one or more temperatures to be known inside the building.

[0166] The installation may also include: - one or more sensors for detecting the configuration of the building's openings, - one or more sunlight sensors, particularly on the building's facades, - sensors for the presence of users in the building.

[0167] An embodiment of a ventilation management method in a building is now described with reference to Figures 4 to 7. The method can be applied to the installation as described above. Alternatively, the method can be applied to a simpler building that does not include a motorized shading system.

[0168] The management process is implemented by means of device 33, such as mobile terminal 33, and more particularly, by means of a computer application running on device 33, which may be connected to a server located remotely from the installation. Device 33 may be very simple and include or be connected to: - the thermometer 99 inside the building, - the means of obtaining a forecast of the outside temperature of the building for the coming hours and possibly of obtaining the wind strength for the coming hours, - computing resources to perform simulations which are described below.

[0169] In other words, the management process can be implemented by a system with a distributed architecture, with different elements of the system located at a distance from each other and communicating with each other.

[0170] The method allows the ventilation of at least one first zone ZI of building B, equipped with an opening 1, to be managed by: - configuration of at least one first manually operable opening 401 and equipping opening 1 with at least one first zone Zl, and, possibly, configuration of an operating mode of an electromechanical device for occulting the opening 1 of at least a first zone Zl.

[0171] The first zone Zl can therefore be located: - in a ventilation situation in which at least one first opening 401 is open, or - in a situation of absence of ventilation in which the first opening 401 is closed.

[0172] In each of these situations, the electromechanical shading device can be opened or closed as needed and / or the control automation of the electromechanical shading device can be activated or deactivated as needed.

[0173] The process mainly comprises the following steps: - detection of an event or a time, - simulation E2 of a temperature evolution in at least one first zone Zl of building B during a specified future period under the assumption of a ventilation situation in which, for example, the first opening and possibly the electromechanical shading device are open, and of a temperature evolution in at least one first zone Zl of the building during the specified future period under the assumption of a situation without ventilation in which, for example, the first opening and possibly the electromechanical shading device are closed, - communication E3 of simulations to a user and / or emission E4, to the attention of a user, of a recommendation to ventilate or not ventilate at least a first zone Zl during the specified period to come.

[0174] Preferably, prior to or during the detection step El, the method includes a step for defining at least one time range during which the user cannot: - operate at least one first opening 401, - nor possibly open or close the electromechanical blackout device.

[0175] This time period is, for example, in the case of a dwelling, a sleeping period for the occupants, for example, a period from 10 p.m. to 7 a.m. the following morning. Such a time period is, for example, defined and personalized for the building's occupants. Such a time period may also differ depending on the day of the week.

[0176] This time period is, for example, in the case of an industrial or commercial building, a period when the building is unoccupied by staff, for example, a period from 7 p.m. to 6 a.m. the following morning. Such a time period may also differ depending on the day of the week. For example, the period extends over the entire day on Saturday and Sunday.

[0177] Time slots can also be defined automatically by learning and / or using sunshine information.

[0178] In the event detection step El, the event can be an action by the user on the installation or on device 33. In particular, the action can be an action prior to the coming predetermined period and during which the user predetermines this coming predetermined period, i.e. he defines the start time, the end time and the duration of the coming predetermined period.

[0179] Thus, once the time range is defined, when device 33 detects the start time of the range, it immediately initiates step E2. Alternatively, a user planning: - a period when he will not be able to influence the building's ventilation (for example, corresponding to an earlier bedtime), or - An unusual period of building vacancy can signal this situation to device 33. In practice, this signal instructs device 33 to immediately implement step E2. This signal should also preferably include an indication of the duration of the upcoming period during which the user will not be able to control the building's ventilation.

[0180] During step E2, device 33 performs simulations. It carries out: - firstly, a first simulation of the temperature evolution in at least one first zone ZI of building B during the specified upcoming period during which the user will not be able to control the ventilation, and assuming a ventilation situation, and - on the other hand, a second simulation of the evolution of the temperature in at least one first zone ZI of building B during the specified period to come where the user will not be able to act on the ventilation and in the hypothesis of a situation of absence of ventilation.

[0181] The first simulation is preferably carried out assuming that the first opening(s) 401 of the first zone ZI are fully open and that the electromechanical shading device is open for the entire determined period.

[0182] The second simulation is preferably carried out assuming that the first opening(s) 401 of the first zone ZI are closed and that the electromechanical shading device is closed for the entire determined period.

[0183] Other simulations can be implemented with respect to intermediate configurations, including: - a simulation where the opening(s) 401 would be open and the automatic control of the electromechanical shading device would be deactivated (or non-existent), or

[0184] - a simulation where the opening(s) 401 would be open and the automatic system of the control of the electromechanical blackout device would be activated, or - a simulation where the opening(s) 401 would be closed and the electromechanical blackout device would be deactivated (or non-existent). - a simulation where the opening(s) 401 would be closed and the electromechanical blackout device would be activated.

[0185] Other simulations may take into account intermediate positions of the openings (partially open or closed) or of the shading devices (partially open or closed).

[0186] Alternatively, or in addition, the simulations can be based on a plurality of open windows acting in the same room or in different rooms and creating air current situations, either desirable because they contribute to accelerating natural ventilation in the area, or undesirable. Appropriate parameterization of the interactions between several windows can thus lead to specific simulation results.

[0187] These simulations mainly use a forecast of the evolution of the temperature outside the building during the determined period and a heat exchange model between the outside of the building and the first zone Zl, in order to determine the evolution of the temperature in the first zone Zl.

[0188] A first example of a simulation result is shown in [Fig. 6] and a second example of a simulation result is shown in [Fig. 7]. In these figures: - Curve A represents the predicted evolution of the temperature outside the building over the entire specified period, - Curve B represents the calculated or simulated evolution of the temperature inside zone Zl of the building during the entire determined period, assuming ventilation throughout this entire determined period. - Curve C represents the calculated or simulated evolution of the temperature inside zone Zl of the building during the entire specified period, assuming no ventilation during this entire specified period. - The double arrow T represents the time that must elapse from the beginning of the period until ventilation has a positive effect on reducing the temperature inside the first zone Zl, assuming no ventilation during this entire specified period. - the double arrow t represents a duration during which the temperature in the first zone Zl is below a given comfort threshold.

[0189] In the simulations shown in Figures 6 and 7, it can be seen that, in certain configurations (for example when the outside temperature is higher than the temperature inside the first zone Zl, at the beginning of the determined period), ventilation first has an effect of increasing the temperature in the first zone Zl, for a duration T, then has an effect of decreasing the temperature in the first zone Zl, that is to say that after this duration T, the temperature in the first zone Zl is lower than it would be in the absence of ventilation.

[0190] During step E3, the device 33 communicates to the user the results of the two simulations mentioned above, namely the simulation with ventilation and the simulation without ventilation. This communication can take several forms. For example, a graph similar to that in [Fig. 6] or [Fig. 7] can be displayed on a graphical interface of the device 33. Alternatively, certain numerical characteristics of the simulations can be displayed on the interface of the device 33. These characteristics may include: - an estimate of the time at which the outside temperature of the building will be equal to the temperature in the first zone Zl, and / or - an estimate of the temperature in the first zone at the end of the specified period, and / or - an estimate of a duration t during which the temperature in at least one first zone is below the first comfort threshold.

[0191] Each simulation can thus include the calculation of a comfort index, based in particular on the durations (T, t) of temperature exceedances of thresholds in at least one first zone during the determined period. This index can have a greater or lesser influence on establishing a recommendation, which is described below.

[0192] Based on this information, the user can decide whether to configure ventilation or the absence of ventilation in the first zone Zl for the specified upcoming period. In other words, the user acts on these recommendations by opening or closing the window(s) before the specified upcoming period. Specifically, the user can configure the window(s) 401 of the first zone Zl to the open or closed position, and can configure the shading device to the open or closed position. Furthermore, in the case of an electromechanical shading device, the user can configure the activation or deactivation of the automatic control associated with that electromechanical shading device.

[0193] The communication of this information can also take the form of recommendations to open or close an intermediate door between two zones, so as to promote or on the contrary avoid drafts when the user is advised, during the communication step, to open several openings in different zones or several openings in the same zone.

[0194] In addition to or as an alternative to communication step E3, device 33 may, in step E4, issue a recommendation to the user regarding whether or not to ventilate the first zone Z1. This recommendation is based on the results of the simulations described above. In particular, the recommendation takes into account: - reaching a potential comfort temperature threshold, particularly at the end of a given period, - the magnitude of the temperature increase in zone Zl at the beginning of the ventilation period, - the duration for which the temperature in zone Zl is increased compared to a situation of no ventilation at the beginning of the ventilation period, - the presence or absence of a user in the Zl zone during the specified period.

[0195] Advantageously, where the installation includes an electromechanical motorized shading device, the method may include one or more motorized control steps for the screen 2 fitted to the opening 1. This motorized control step or steps are advantageously carried out automatically during the specified period. This step or these steps mitigate the negative effects of ventilation on the internal temperature of the first zone Zl. For example, a command to close the screen 2 at the beginning of the ventilation period limits the temperature increase in the first zone Zl. For example, a command to close the screen 2 at the end of the ventilation period prevents an excessive drop in temperature in the first zone Zl.For example, a command to open screen 2 for the remainder of the specified period allows maximizing the refresh rate of the first zone Zl.

[0196] Thus, preferably, during the specified period: - Screen 2 is open when the outside temperature of the building is lower than the temperature in at least one first zone, unless the temperature in at least one first zone is lower than the first comfort threshold, and - screen 2 is closed the rest of the time or when an outside temperature outside the building is higher than a temperature in at least one first zone.

[0197] Preferably, the simulations mentioned above take into account such operation of the automatic motorized electromechanical occulting device, that is to say that the simulations take into account the fact that during the determined period, in a ventilation situation, the screen 2 will be open in certain time phases and closed in other time phases.

[0198] Preferably, the recommendation to ventilate or not ventilate is issued during step E4: - continuously for the specified period, or - at regular intervals during the specified period, or - whenever the configuration needs to be changed during the specified period, i.e., whenever it would be relevant to operate the opening(s) 401 to change their configuration or to activate or deactivate the automatic control of the electromechanical shading device. If sensors detecting the configuration of the opening(s) 401 are in operation, the recommendation may not be sent if the opening(s) are already in the recommended configuration.

[0199] Thanks to such an emission step, it is possible, during a specified period and in the event of the user's unexpected presence or unforeseen availability (for example, the user waking up in the middle of the night), to modify, by the user's action, the configuration of the opening(s) 401 and / or the configuration of the electromechanical shading device in order to optimize ventilation. Specifically, for example, based on a continuous recommendation, the user can, during the night, open the opening(s) 401 even if they were not open at the beginning of the night. Alternatively, the user can, during the night, close the opening(s) 401 even if they were open at the beginning of the night.

[0200] Depending on the application, the recommendation may be more or less discreet. It is understood that, if a recommendation is to be issued during a user's sleep phase, the preferably discreet notification will simply display the recommendation. In the case of an industrial or commercial building, the recommendation may include an audible signal. This allows personnel who are exceptionally present in the building to modify the ventilation configuration of the first zone Z1.

[0201] Preferably, the process further comprises the following steps: - simulation of a temperature evolution in a second zone Z2 of the building during the specified period under the assumption of ventilation and of a temperature evolution in the second zone of the building during the specified period to come under the assumption of no ventilation, - communication of the simulations to a user and / or issuing, to a user, a recommendation to ventilate or not ventilate the second zone Z2 during the specified period to come.

[0202] Consequently, the user can be informed simultaneously whether or not to ventilate different areas of the building. Therefore, in a single operation, they can configure all the ventilation settings for the different areas of the building. Specifically, the user can be informed simultaneously of the overall building ventilation configuration that appears... more appropriate. It therefore does not receive messages that are staggered in time and that concern different areas of the building. Furthermore, the ventilation of different areas of the building can mutually influence the temperature of a given area. Thanks to the solutions according to the invention, users can make informed and sometimes counterintuitive decisions regarding building ventilation. In particular, they will be able to determine whether it is appropriate to open a window or door to cool the building even when the temperature outside is higher than the temperature inside.
