Description

Method for monitoring environmental parameters and design, assembly and use thereof

TECHNICAL DOMAIN

The invention relates, inter alia, to a method for monitoring environmental parameters in one or more office or living spaces, with emphasis on the first. By using a simple sensor module that can be applied in an inventive manner in a non-disturbing manner, environmental parameters that have a major influence on user comfort can be monitored and measures can be taken if necessary.

BACKGROUND ART

The applicant noted that in more and more companies, one of the key issues that employees attach importance to in office and work environments is health. In doing so, we need to look beyond the known aspects involved, such as ergonomics, lighting and the like, as well as newer, more specialized problems such as particulate matter, CO2 percentage in the air, VOC, humidity, temperature, etc., as well as the interplay between all those factors. However, studies indicate that these small factors can be very important for both employee health and employee comfort, which means that an improvement in these circumstances (through structured monitoring and acting in problem situations) will have a huge impact on work efficiency, namely by reducing absence due to illness, as well as by increasing employee productivity. Sensors that can measure these things are known, but until now they have been used in an almost random way for measurements of environmental parameters in an office or living space. By providing a method for this that adequately measures and monitors the correct parameters, the applicant meets a rising demand in the sector. In addition, the method allows to draw up a plan based on objective data for an optimal distribution of users over the available spaces (based on personal preferences that are objectified, and knowledge of the environmental parameters in the spaces concerned).

Finally, it should be noted that current measurement systems that monitor similar parameters cannot dynamically handle alarming values. Upon detection of an exceeded value, these will typically be an alarm

2018/5050

Send BE2018 / 5050 and register this in a logbook, but little or no additional measures will be taken.

It is an object of the present invention to find a solution to at least some of the aforementioned problems.

DETAILED DESCRIPTION

Unless defined otherwise, all terms used in the description of the invention, including technical and scientific terms, have the meaning as generally understood by those skilled in the art of the invention. For a better assessment of the description of the invention, the following terms are explicitly explained.

2018/5050 ^J BE2018 / 5050

One, the, and the reference in this document to both the singular and the plural unless the context clearly assumes otherwise. For example, a segment means one or more than one segment.

When approximately or around in this document is used with a measurable quantity, a parameter, a duration or moment, and the like, variations are meant of +/- 20% or less, preferably +/- 10% or less, more at preferably + / 5% or less, even more preferably +/- 1% or less, and even more preferably +/- 0.1% or less than and of the quoted value, insofar as such variations apply in the described invention. Here, however, it is to be understood that the value of the quantity at which the term is used approximately or around is itself specifically disclosed.

The terms include, comprising, consisting of, provided with, containing, containing, including, including, including, including its synonyms and its inclusive or open terms indicating the presence of what follows, and which do not exclude or preclude the presence of other components, features, elements, members, steps, known from or described in the prior art.

The term VOC particles, or volatile organic matter particles, is also known under the term VOC particles, which stands for volatile organic compounds.

The term work surface refers to a substantially flat structure with a limited thickness that is typically essentially horizontally positioned (in use). The work surface is at a height suitable for being worked on by a user (with his hands), and is typically positioned about 20-60 cm below the head during use. The height above the ground can vary (standing desk vs. sitting desk and the like). A possible example of a work surface is the (work) surface of a desk, a work table (for example for a draftsman or craftsman) and others.

In a first aspect, the invention relates to a method for monitoring environmental parameters in a plurality of office or living spaces with a work surface, each of the office or living spaces comprising at least one sensor module, which sensor module comprises a measuring chamber for circulating ambient air therethrough and which sensor module is suitable for registering values of at least two, preferably at least three, of the following

2018/5050 ^h BE2018 / 5050 ambient parameters for the ambient air in the measuring chamber: temperature, air humidity, air pressure, number of CCfc particles per million, number of volatile organic dust particles (VOC particles) per million; wherein the sensor modules are adapted to communicate with a central processing system, and wherein the method comprises the following steps:

the installation of the sensor modules in the work surfaces, wherein the sensor modules are protruding at least with a part of the measuring chamber relative to the working surfaces at the top of said working surfaces, wherein the projecting part of the measuring chamber is provided with one or more openings outside;

b. receiving ambient air in the measuring chamber;

c. the sensor modules periodically registering the values for said at least two ambient parameters for the ambient air in the measuring chamber;

d. periodically sending the recorded values for the environmental parameters from the sensor modules to the central processing system;

e. evaluating the values for the environmental parameters on the basis of one or more predetermined limit values for the environmental parameters, wherein evaluating the values is performed by the sensor module and / or by the central processing system.

The applicant noted that in many (office) spaces, a multitude of environmental parameters can have a strong effect on health and comfort, and thus on the efficiency of the people present there. In addition to direct influence, there is also a strong synergistic effect between many of the environmental parameters, such as, for example, a low humidity combined with a high number of VOC particles, which is detrimental. By registering a number of the environmental parameters (at least two, preferably at least three, more preferably at least 4 or 5, and most preferably with additional parameters), the conditions in a room can be accurately monitored, and on the basis of predetermined preference settings (can be based on a preference, or simply certain limits) these parameters are evaluated. If exceeded, a responsible person can be notified and / or automatic measures can be taken to regulate the exceedance.

Because in practice, and certainly in office spaces, those present slightly above the level of a work surface, such as a desktop, spend the most time with the face and arms, this height is therefore the most (only) relevant for taking the measurements.

2018/5050 'BE2018 / 5050, and even recommended in certain jurisdictions (if not mandatory). In order to prevent mobile sensor modules from falling, being moved, or even being stolen, the applicant partially installs the sensor module in the work surface, the sensor module partially protruding above the work surface. Along this protruding part, the ambient air is taken in, and that air is then analyzed for the ambient parameters. This ensures that the air is controlled which the user effectively inhales / feels, in contrast to known systems that are typically built into the ventilation, which offers a wrong representation of the ambient air, or of mobile sensors, which are often displaced somewhere for free stand in the way and are therefore not positioned in the right place to be able to perform good measurements.

In an alternative (or additional aspect), the invention relates to a method for monitoring environmental parameters in a plurality of office or living spaces with a work surface, each of the office or living spaces comprising at least one sensor module, which sensor module comprises a measuring chamber for measuring circulation of ambient air therethrough, and which sensor module is suitable for recording values of at least two, preferably at least three, of the following ambient parameters for the ambient air in the measuring chamber: temperature, humidity, air pressure, number of CCh particles per million, number of volatile organic dust particles (VOC particles) per million; wherein the sensor modules are adapted to communicate with a central processing system, comprising the following steps:

a. coupling a portable electronic device, preferably a user's smartphone or tablet, to one of the sensor modules, preferably wherein the coupling is automatically activated upon an approach from the electronic device to the sensor module below a predetermined distance, wherein the electronic device is provided with a user interface and is configured to receive one or more quantified or quantifiable feedback values via the user interface;

b. subjectively quantifying the user's environmental parameters on the electronic device, based on one or more quantified or quantifiable feedback values;

c. sending the feedback values to the central processing system;

d. controlling the sensor module coupled to said electronic device for registering the values for the at least two environmental parameters upon receipt of feedback values from an electronic device;

2018/5050 ° BE2018 / 5050

e. transmitting the recorded values for the environmental parameters from the sensor modules to the central processing system;

f. evaluating the received values for the environmental parameters based on the feedback values, wherein evaluating the values is performed by the central processing system.

Most of the aforementioned advantages naturally also apply to the current embodiment. In doing so, the applicant wished to build on the principle that a built-in sensor module allows for the subjective experiences of a person in terms of environmental parameters (feeling of cold, humidity, dust in the air, etc., or can it simply be a general feeling - good or bad feedback to the system) easy to register, preferably via an app on a smartphone or tablet, and to be able to test these against objective parameters (measured values). For example, a profile can be drawn up for the user on the basis of such data, on the basis of which structural solutions can be provided by a supervisory authority (for example, the employer). These solutions can be simple, such as increasing temperature settings for a room or building, purchasing equipment for air purification, etc., or more subtle, such as adjusting a person's workstation (switching with a person who has a more suitable profile for the room, spaces often have a very different profile). This specific application is particularly useful for larger office spaces where a multitude of sensor modules for a multitude of users can create such profiles. In this way every space can be used optimally.

The sensor modules are preferably built into the work surfaces, the sensor modules protruding at least with a part of the measuring chamber relative to the working surfaces at the top of said working surfaces, wherein the projecting part of the measuring chamber is provided with one or more openings to outside.

The sensor module coupled to said electronic device can be recorded in a number of ways. Either the electronic device is user-specific (for example, a smartphone), so that it is known where the user normally sits (in his or her desk), and the sensor module is controlled there to record the values. An alternative, which is certainly useful for more mobile users, is that the closest sensor module, relative to the electronic device, is automatically controlled to take the measurement (where height can also preferably be taken into account to measure on the right floors) ). In case of

2018/5050 ^ΒΕ2018 / 5050 a non-user-bound electronic device, the user will first have to identify himself, so that the system again either automatically controls the 'correct' sensor module (from the user's desk), or again controls the nearest sensor module .

In the following, further elaborations are presented for both the invention in the first aspect and in the second aspect, since these variations are on one another with the same basis. Thus, unless explicitly impossible, what follows should be interpreted as extensions to both aspects. Moreover, it would be easy for the person skilled in the art to adjust the aspects in light of each other to allow any extension, and as such also falls within the scope of the invention.

Preferably, the sensor module records at least every 15 minutes, more preferably at least every 10 minutes, still more preferably at least every 5 minutes, still more preferably at least every 2.5 minutes, most preferably at least every minute, the value for one or more of the environmental parameters (preferably all). It should be understood that, depending on the sensitivity of the specific application, this period can be adjusted (clean room compared to standard office space, for example).

Preferably, the sensor module sends the recorded values at least every 3 hours, more preferably at least every hour, more preferably at least every 30 minutes, and most preferably at least every 10 minutes, to the central processing system. It goes without saying that, as with the previous registration period, this is highly dependent on the field of application.

In a preferred embodiment wherein the electronic device is coupled to a user profile for the user, and one or more preferred values and / or ranges are formulated for one or more environmental parameters on the basis of the feedback values and the received values for the environmental parameters preferred values and / or ranges are linked to the user profile.

As discussed earlier, by creating a user profile for a user, an optimal workstation distribution can be set up on an objective basis, or an optimum environmental regime can be defined for a room (and the user linked to it) (certain temperature, certain ventilation strength,

2018/5050 ^χυ ΒΕ2018 / 5050 humidity, etc.). Some will want a lower ambient temperature than others, which will be one of the most determining factors. In addition, some will also experience certain deviations in one or more environmental parameters as more or less disturbing (for example, humidity, draft, etc.), and in this way structural problems can still be minimized in terms of effect, for example if a building has certain defects that are difficult to can be released, such as a draft, or a lower temperature, in certain spaces.

In a preferred embodiment, the sensor modules comprise a communication unit suitable for wireless communication with the central processing system.

The wireless communication is preferably done via WiFi. Note that the invention is by no means limited to communication via a wireless connection, and that the sensor modules may equally well be connected to the central processing system via a wired connection (ethernet). In such a situation, for example, it is possible to provide a wired connection for the sensor modules in the work surface. Additionally or alternatively, communication can be via Bluetooth, wireless meshing, ZigBee, LoRa (long range) and / or GPRS, whether or not with a local intermediate station that in turn communicates with the central processing system (again via one of the above options or wired) .

In a preferred embodiment, each of the sensor modules are provided with a separate identification, and the recorded values are sent to the central processing system, these recorded values being linked to the identification of the sensor module that has recorded the recorded values.

Certainly in contexts where (over a floor, or building, or even complex) a multitude of sensor modules are placed, it is crucial to be able to attribute data to a specific location, to take appropriate action at the location where a problem is located . In addition, good mapping of data also makes it possible to distinguish patterns, for example in the case of problems with air humidity, a leak can be traced to one or more spaces, but moreover a connection between certain spaces can also be exposed unexpectedly. This can certainly be important in applications where a certain hygiene and / or strict environmental parameters must be followed (preparation or processing of

2018/5050 ^{x ±} BE2018 / 5050 food, medicines, etc.), and contamination of the production process can be traced.

The sensor modules are also preferably provided with a positioning element that can record the location of the sensor module and transmit it to the central processing system, so that a map can be kept of the location of each of the sensor modules, without these having to be supplemented and adjusted manually each time turn into.

In a preferred embodiment, the steps of recording and transmitting the values of the environmental parameters by the sensor modules are performed periodically with identical or non-equal predetermined periods, the sensor modules evaluating the recorded values on the basis of the predetermined limit values, characterized in that upon detecting an exceedance of one or more predetermined limit values for the environmental parameters by the recorded values, the sensor module essentially automatically transmits the exceeding registered value or exceeding values to the central processing station, preferably accompanied by an alarm message.

In a further preferred embodiment, when detecting an exceedance of one or more predetermined limit values for the environmental parameters by the recorded values, the sensor module reduces the period of recording the values of the environmental parameters and / or the period of sending the recorded values.

Upon detection of an 'alarm situation', exceeding preset ranges for the parameters, the sensor module will push measurements to the central processing system instead of sending measurements at predetermined times (or where the central processing system 'bulges' measurements from the sensor modules). In an alternative embodiment, the central processing system evaluates the recorded values, and controls the sensor module to record and / or transmit the values with a lower period.

The known systems are pre-programmed to take a measurement at set intervals and to send it to a central unit. In the event of detection of an alarming value, insufficient follow-up is provided in this situation. For this reason, the applicant sets up a regime that increases the frequency of pushing the measurements (registrations) through the sensor modules in order to better follow the problem. In addition, such a method also allows to better visualize the problem, and even to monitor its extension (optionally by

2018/5050 ^Le - BE2018 / 5050 also instruct 'adjacent' sensor modules to temporarily increase the frequency of transmitting measurements).

In a preferred embodiment, when an exceedance of one or more predetermined limit values for the environmental parameters is detected by the recorded values and / or by the transmitted values, an alarm message is sent to one or more users.

Such an alarm message can offer several advantages. On the one hand it can give rise to a relocation of the user to another room (whether or not temporarily, because he or she is pointed to a problem. On the other hand, an authorized user can immediately intervene, for example by adapting the HVAC system, or request a maintenance, etc. Finally, such alarms can also be compiled to get a structural overview of the characters of each room, and to form an image where certain problems occur, allowing structural solutions to be found (such as to isolate) or to move users from space (if some have a certain preference, or a lesser opposition, to certain problems).

In a preferred embodiment, the step of registering the values of the environmental parameters is performed periodically with a first period and the step of transmitting the values of the environmental parameters through the sensor modules is periodically performed with a second period, the first period being lower is then the second period, preferably at least 5 times lower, more preferably at least 10 times lower. The sensor modules preferably comprise an internal processing unit suitable for evaluating the recorded values of the environmental parameters on the basis of predetermined limit values therefor. Based on the evaluation, the sensor module can then send the registered values to the central processing system or not. Moreover, additional measures can also be taken, such as lowering the first period and / or lowering the second period. By lowering the first period, the environmental parameters can be monitored even more strongly by the sensor modules in order to respond more quickly to (permanent) exceedances of limit values. By reducing the second period, the central processing system is more often kept up-to-date on the registered values, and from there a better evaluation can follow (possibly also on the basis of values from other sensor modules, for example with their location in mind).

2018/5050

BE2018 / 5050

By having the sensor modules with a higher sample rate record values than having them sent to the central processing system, this is not unnecessarily burdened. The sensor modules can thus perform a first screening, whereby they regularly check in at the central processing system in the normal parameter range. This also avoids unnecessary data storage if no exceedances are observed, without structural trends not being noticed, since measurements are still coming in at regular intervals. The applicant noticed that the sample rate of the measurements by the sensor modules may be at least 5, preferably at least 10, times higher than sending the measurements for an ideal regime.

In a preferred embodiment, the sensor modules comprise an internal processing unit adapted to evaluate the recorded values against predetermined limit values for the environmental parameters, preferably wherein the method comprises a step of evaluating the recorded values against the predetermined limit values by the internal processing unit in situations where the sensor modules cannot send the recorded values to the central processing system.

The invention thus avoids that in the event of a power failure, problems with the connection between central processing system and one or more sensor modules, or others, the recorded values that cannot be sent to the central processing system would be lost. By temporarily storing it internally and forwarding it when the connection is restored, the environmental parameters can continue to be structurally monitored. In addition, a report is preferably made to an administrator and / or users of a forwarding problem, since this can also be caused by an exceeding of the environmental parameters (fire, humidity, ...).

In a preferred embodiment, the sensor modules are releasably arranged in the work surfaces.

In a preferred embodiment, the sensor modules are suitable for recording values of at least three of the following ambient parameters for the ambient air in the measuring chamber: temperature, air humidity, air pressure, number of CO2 particles per million, number of volatile organic dust particles (VOC particles) per million; and wherein the sensor modules are further suitable for registering

2018/5050

BE2018 / 5050 at least one of the following ambient parameters for the ambient air in the measuring room: sound intensity, light intensity, motion detection.

The extension to sound intensity, light intensity, motion detection opens a new range of possibilities, such as in hospitals, care homes, and the like, where sound intensity and motion detection are particularly strong parameters for observing problems (cries for help, a fall, a medical attack, etc.) .

In a preferred embodiment, each recorded value is sent to the central processing system together with a time stamp. Providing a time stamp allows a user to analyze the collected data on the central processing system (recorded values). For example, the progression of certain problems can be identified (such as the spread of moisture problems, or infections with certain contaminants), and patterns can be discovered. The user can prepare a graphical representation based on the physical locations of the sensor modules, and the corresponding recorded values at a specific time based on the time stamps. By varying the times for which the display is set up (return, advance), the evolution of a certain problem can be clearly charted, and the cause can be traced more easily.

In a preferred embodiment, the central processing system is adapted to automatically start certain procedures upon detection of certain alarm situations. For example, the HVAC installation can be controlled, the thermostat, or messages can be sent or displayed automatically to inform / warn users or managers, or official bodies can be contacted (fire brigade, ambulance, etc.).

In a third aspect, the invention relates to a sensor module for monitoring environmental parameters in an office or living space, comprising a measuring chamber and a hardware space, which hardware space is completely closed off from the measuring chamber, the measuring chamber and the hardware space surrounding are positioned through a housing, the housing comprising one or more openings, which openings allow the circulation of ambient air from outside the sensor module through the measuring chamber, wherein the sensor module is provided with one or more sensors positioned to measure the ambient parameters in the measuring chamber, the environmental parameters include at least two, preferably at least three, of the following parameters: temperature, humidity, air pressure, number of CO2 particles

2018/5050

BE2018 / 5050 per million, number of volatile organic dust particles (VOC particles) per million; wherein the sensor module is adapted to be built into a work surface, preferably a desktop, the measuring chamber protruding at least in part relative to and above the working surface, the openings of the measuring chamber being above the working surface. The openings are preferably positioned in a lateral direction (to ensure free inflow even if this would be covered with paper, for example. A radially projecting and overhanging collar is provided at the top of the sensor module to keep the openings free further , and also to prevent liquids from entering the measuring chamber (for example, in the event of spillage) The hardware room is provided with a component for communicating with the central processing system, preferably in a wireless manner (WiFi and others), although a wired connection It is also possible (combined or not as a fail safe), with the understanding that the largest possible part of each of the sensors is positioned in the hardware room.

The applicant noted that the sensor module must be adapted so that it can be built into a work surface, for example a desktop. In this way, it is positioned in the (legally) correct way to register the necessary values, since this height is also used for working / sitting (and the head of the people is located). Existing systems are typically provided for installation in ventilation systems, and are therefore not specifically adapted for installation in a work surface (since existing systems did not take into account the need for compactness, specific construction of the work surface, possibility of inflow of suitable ambient air , etc.). The sensor modules of the invention are compact, so that they are easily built into a work surface (tabletop) without taking up too much space. For that reason, a module is provided of which only one (part of the) measuring chamber protrudes above the working surface. The rest is in or below the work surface, and therefore out of sight and reach of the user. Moreover, this part that protrudes does not have to protrude far, for instance over a distance between 0.25 cm and 10 cm, preferably between 0.5 cm and 5 cm, more preferably between 1.0 cm and 2.5 cm, for example 1.1 cm, 1.2 cm, 1.3 cm, 1.4 cm, 1.5 cm, 1.6 cm, 1.7 cm, 1.8 cm, 1.9 cm, 2.0 cm, 2.1 cm, 2.2 cm, 2.3 cm, 2.4 cm or intermediate values. A minimum height of the projecting part is needed to ensure that sufficient ambient air can enter the measuring chamber.

The sensor module is preferably adapted as discussed in one or more of the embodiments for the method of this document. In the presence of an internal processing unit and / or a communication unit for communicating

2018/5050 ^χσ ΒΕ2018 / 5050 with the central processing system, these are preferably mainly if not completely included in the hardware space.

In a preferred embodiment, the environmental parameters include one or more of the following parameters: sound intensity, light intensity, motion detection.

The sensor module is preferably provided with a connector to be connected to an external power source. This connector is preferably located on the outside of the hardware space and supplies power to the electronic components of the sensor module. The sensor module is further preferably provided with an internal battery for supplying power to the electronic components, whether or not rechargeable at the external power source.

In a preferred embodiment, the sensor module is substantially cylindrical, the measuring chamber being located at a first end of the substantially cylindrical sensor module and the openings being located in the cylinder shell. The sensor module preferably comprises at the first end a radially protruding collar for protecting the openings, and preferably also a radially protruding edge at the level of the lower limit with which the measuring chamber protrudes from the working surface. This protruding edge ensures that the sensor module cannot be pushed deeper when objects rest on it or other downward forces are exerted.

In a preferred embodiment, the measuring chamber is detachable from the rest of the sensor module. In this way it can easily be changed, but access to the hardware space can also be made possible.

In a preferred embodiment, the housing of the sensor module comprises high-density polyethylene (HDPE). More preferably (if present), the protruding edge and / or collar comprise a polycarbonate (PC).

In a fourth aspect the invention relates to a work surface, preferably a desktop, provided with at least one sensor module according to this document, characterized in that the measuring chamber is at least partially protrude with respect to the work surface, at the top of said work surface.

In a fifth aspect, the invention relates to a use of a sensor module according to this document, for monitoring environmental parameters in an office or living space, wherein the sensor module is detachably built into a substantially horizontally positioned work surface, preferably a desktop, the sensor module at least with a part of the measuring chamber protruding with respect to the working surface at the top of said working surface, and wherein the protruding part of the measuring chamber is provided with one or more openings to the outside.

In the following, the invention is described a.d.h.v. non-limiting examples illustrating the invention, and which are not intended or may be interpreted to limit the scope of the invention.

EXAMPLE 1: SENSOR MODULE

Figures 1A-B and 2A-G describe a sensor module according to the invention. The sensor module is approximately cylindrical. This comprises a hardware part or space (2) and a measuring chamber (1) at opposite ends of the longitudinal axis of the sensor module. Hereby as much hardware (6) as possible is kept out of the measuring chamber (1) and placed in the hardware room (2), where it is better protected (in or under the work surface). Certain components (7) of the sensors are of course still present in the measuring chamber (1) which evaluate the ambient air present there. The measuring chamber (1) is provided on its jacket with a plurality of openings (3) for admitting and leaving ambient air. Preferably, at least two zones are present where a plurality of openings (3) are provided, more preferably standing on the opposite side of the measuring chamber relative to each other. In addition, the sensor module is provided with two radially extending collars (4, 5).

EXAMPLE 2: OBJECTIVATION OF SUBJECTIVE EVALUAITES / VALIDATIONS

In its second aspect, the invention relates to a method for linking subjective data of users regarding environmental parameters to objective measurements, and on the basis thereof solving certain problems. In offices with a multitude of separate (whether or not closed) offices, there are always variations in environmental parameters. The most common or obvious of these is temperature, but is certainly not limited to this. In addition, each person has different preferences and perceptions of these environmental parameters. Some prefer a higher ambient temperature than others to update or be in. Still others, for example, may have a very limited range in terms of feeling 'good' temperatures (quickly too cold, but also quickly too hot), while others are much less affected by this.

The intention of the invention is also to get started with these personal experiences. Not only can a happier employee be achieved in this way by trying to achieve his preferences, but also a healthier employee, since these preferences, even though they are sentimental, are often controlled by the body to reflect effective, physical problems. .

By giving users the possibility to give feedback at any time on one or more environmental parameters with an individualized electronic device (either a smartphone or a common device to be logged on to). For example, this feedback can be a score of 10, or simply too high - too low - neutral, or other. By linking this to the effectively registered value for the parameter (s) by a sensor module, a profile can then be built up in the long term for the user, in which the preferences are objectively clear. The sensor module that takes care of the registration of the parameter (s) can be fixed in proximity, or can be a coupled sensor module to the device, and thus to the user, if it is an effective user-bound electronic device, namely the sensor module in the user's desk. Based on the profiles prepared for the users, an optimization of the spaces can then be achieved by moving users to suitable spaces for their profile.
