Method and device for computer-aided determination of building automation parameters of a building

The present invention relates to a method and a device for the computer-aided determination of building automation parameters of a building.

Building automation parameters of a building are used to regulate the behavior of a building in terms of Hei ^¬ pollution, air-conditioning, shading, lighting, ventilation and the like. The aim of building automation is to achieve with the help of used to control Gebäudeautoma ^¬ tisierungsparametern high energy efficiency and -on- savings while maximizing the comfort of the groove ^¬ zer of the building. The building automation ^¬ parameters are used to control a heating system, processed and determined based on data detected by sensors of the building of an air conditioner, a sun protection device (eg blinds), lights, fans and the like. For this purpose, for example, one or more Temperatursenso ^¬ ren, moisture sensors, sunshine sensors (eg sunshine and / or sunshine sensor, optionally with a light sensor arranged behind it), wind sensors, light sensors and the like are distributed over the building.

Basically, with an increasing number of processable sensor data, an improvement of the regulation by the building automation in terms of minimizing the energy consumption of the building is possible. However, as the number of sensors installed in the building increases, so does the cost of manufacturing the building and maintaining the sensors in an undesirable manner.

It is an object of the present invention to provide a method and a device for the computer-aided determination of building automation parameters of a building, with which chen a more energy efficient building automation enabled ^¬ light is.

These objects are achieved by a method according to the features of patent claim 1 and a device according to the features of claim 15. Advantageous Ausgestal ^¬ tions emerge from the dependent claims.

A method for computer-aided determination of building automation parameters of a building is proposed. In this a first building automation ^¬ tion is determined with the first building automation parameters for the building, based on one or more classes of local parameters in each case. Local parameters are parameters determined at the location of the building, such as parameters determined by sensors of the building. Local parameters also include those parameters which are or were determined for the location of the building, eg by simulation or calculation.

The one or more classes of local parameters comprise at least a first class of static building data of the building and / or a second class of current Wet ^¬ terdaten for the location of the building and / or a third class of, in particular lying in the past, building ^¬ automation parameters of the building.

By static building data are meant those parameters which the building in terms of its size, the building materials used, in the building building automation units (eg type, type and size of a heating and / or air conditioning device), type and size of a sunshade device (eg blinds ), and the like, characterize insulating materials, insulating properties, and so on.

Up-to-date weather data for the location of the building include weather information recorded or valid at the present time, eg with the help of sensors of the building, and for one predetermined period in the future, forecast weather information. The weather data may be recorded locally at the site of the building or near the building or be determined by Si ^¬ mulation. The weather data may also be provided by one or more weather services for the location of the building. The term "location of the building" is not strictly limited to the exclusive area of the building be ^¬ limits, but includes the place in a broad sense, such as a city, a district or a region or a radius around the place of the building.

The building automation parameters represent such parameters that are used to control the building automation.

The first building automation parameters are adapted as a function of a number of classes of remote parameters of at least one predecessor building, which is located at ei ^¬ nem location other than the location of the building. The number of classes of remote parameters is determined at or for the location of the respective previous building. The number of classes of remote parameters comprises at least the second class of current and / or past weather data at the respective location of the at least one predecessor building.

The term "place of the previous building" or "other place" is not strictly limited to the exclusive area of jeweili ^¬ gen predecessor building, but includes the location in the wider sense, such as a city, a neighborhood, or a regi ^¬ on or within a set distance the place of the previous building.

Subsequently, the adaptation of the first building automation ^¬ sierungsparameter is made based on previously determined scaling factors between the classes of each local parameters and the corresponding classes of remote parameters at the respective location of the at least one Vorgängerge ^¬ bäudes. Furthermore, a device is proposed for the computer-aided determination of building automation parameters of a building which is set up to determine for the building a first building automation with first building automation parameters which is based on one or more classes of respectively local parameters. The one or more classes comprise at least a first class of static building data of the building and / or a second class of current weather data for the location of the building and / or a third class of building automation ^{parameters of} the building that are in the past.

The apparatus is further adapted to control the first to adapt Ge ^¬ bäudeautomatisierungsparameter a function of a number of classes of remote parameters of at least one predecessor building, which is located at a location other than the location of the building. The number of classes of remote parameters at or for the location of the respective predecessor building is determined, wherein the number of remote parameter classes at least the second class of current and / or past data at the respective location of the at least one predecessor building - sums up.

The apparatus is further adapted to perform the adaptation of the first building automation parameters based on previously determined scaling factors between classes of respective local parameters and the corresponding classes of remote parameters at the respective location of the at least one predecessor building.

The approach underlying the invention is based on the fact that not only the information available at or for the location of the building is used to determine the building automation parameters of the building to be controlled, but additionally data from other buildings are processed for improving the building control. The adaptation of the first th building automation parameters is based on the consideration that present in a previous building parame ter which rametern for determining Gebäudeautomatisierungspa be used the previous building in question, in a known relationship between the to be controlled building and the predecessor building an improved Gebäudeau ^¬ tomation by adaptation of the allow first building automation parameters. Thus, it is not necessary for the building to be controlled with additional sensors to be sent ^¬ hen. Instead, the data provided by other buildings (the previous buildings) can be used sensory or computationally or simulated data to adjust the building automation parameters. As a result, a possible "prediction" of the regulation of the building to be controlled makes it possible to minimize the energy consumption of the building to be controlled.

In particular, there is an adaptation of the weather data and / or the weather forecast for the building to be controlled with the help of the weather data of and / or the weather forecast for at least one previous building. By doing so, the weather forecast in the future can be improved with the weather present at the location of the previous building, the relationship of which is known via one or more scaling factors to the weather at the building to be controlled. In this way, for example, weaknesses in the weather forecast for buildings to be regulated, which as a rule originate from meteorological services, can be improved on the basis of measured data which were collected at the location of the at least one preceding building.

A further optimization of the first home automation ^¬ parameter of the first building automation arises from the fact that the number of classes of remote parameters further comprises at least the first class of static building data of a preceding building. This makes it mög ^¬ Lich, effects with regard to necessary or energy consumed for the building to be regulated on the basis of already acquired data of at least one previous building precise predict. This prediction can then in turn be incorporated into the adaptation of the first building automation parameters.

It is further advantageous if, alternatively or in addition to the first class of static building data of the at least one predecessor building, the number of classes of ent ^¬ fernten parameters comprises at least the third class of lying in the past, building automation parameters of a preceding building. From this information it can be deduced that building automation parameters of the previous building what effect, for example in terms of energy consumed and thus the efficiency in the pre ^¬ was predecessor building achieved. This knowledge can in turn be used to adapt the first building automation parameters to improve the building efficiency.

It may furthermore be expedient if the number of classes of remote parameters as an alternative or in addition, a fourth class of by second Gebäudeautomatisierungspa ^¬ parameters of the at least one predecessor building caused building effects encompasses. This makes the already beschrie ^¬ bene efficiency of building automation parameters used for the control of the predecessor building is considered.

Thus a combination of all these classes of remote parameters enables optimization of the first building automation ^¬ sierungsparameter with regard to minimum energy consumption of the controlled building. It is convenient if the scaling factors between classes of respective local parameters and the corresponding classes of remote parameters for the location of the building and one or more ancestor buildings are determined at those other locations that satisfy a predetermined similarity measure / similarity criterion. In other words, a similarity / similarity criterion is examined for pairs of buildings, where one of the buildings of the building pairs is always the building to be controlled. In carrying out the method described above are then taken into consideration only those predecessor buildings, which have a comparable to the to be controlled building on ^¬ which is expressed by the degree of similarity / similarity criterion.

A further expedient embodiment provides that the first class of static building data of the class of local parameters of the building and / or the class of removed criteria of the at least one predecessor building comprises one or more of the following parameters:

a type of building, e.g. Residential building, office building,

Building work (if necessary, divided for the production under ^¬ schiedlicher goods), Warehouse, etc .;

a purpose of use of the building, e.g. Production, warehouse, etc. ;

- a locality of the building, expressed by the Konti ^¬ nent and / or the country in which the building stands, and / or a latitude and longitude and / or a climatic zone in which the building is;

- an orientation of the building in the direction of the sky in order to take account of the influence of the sun or of the position of the sun on the temperature prevailing inside the building;

- Surfaces of external walls and / or roof and / or basement, in order to determine heat gains and / or heat losses, incidence of light and ^¬ same;

- Materials from which the building is constructed in order to determine heat ^¬ profits and heat losses can; such as

- Insulation values of external walls and / or roof and / or basement in order to determine heat gains and heat losses.

A further expedient embodiment of the method provides that the third class of building automation Para ^¬ meters of the building and / or the third class of building ^¬ automation parameters of the previous building comprises one or more of the following parameters:

Control parameters of the building, in particular over time, which are used to control a heating system ge, an air conditioner, a sun protection device (eg blinds), a humidity, the lighting and the like are used;

- Energy consumption data of the building, in particular over time recorded, in order to determine the consumption of electricity or a primary energy source for space heating.

A further expedient embodiment provides that the building and the at least one predecessor building have a similarity or comparability with respect to one or more of the following criteria:

- if the is a geographical location, in particular a latitude, a similarity exists the latitude at least one predecessor within a building vorgege- surrounded bandwidth to the latitude of the controlled buil ^¬ of. An expedient predetermined bandwidth about the latitude of the building may be, for example ± 30 arc minutes (ent ^¬ speaking the traditional sexagesimal), wherein a half-width approximately 110km degrees more or less corresponds to the observed site;

- a country to user habits of Vorgängergebäu ^¬ be able to relate consideration for the adaptation of the user of the controlled building and. In particular, buildings are considered which are located in the same country or in countries with similar user habits;

- a building type in order to make a comparison in terms of use as an office building, production facility or Lagerge ^¬ buildings;

- A building orientation in order to take into account the influence of the sun or the position of the sun on the internal temperature and / or the incidence of light;

Average weather conditions, in order to be able to carry out a simple adaptation of the first building automation parameters, in particular under similar weather conditions.

A further expedient embodiment of the method according to the invention provides that the determination of the scaling factor occurs factors between classes of each local parameters for the location of the building and the corresponding classes of remote parameters for the one or the other places the predecessor or predecessors building by the at least one local Pa ^¬ parameters and the at least one corresponding remote Para ^¬ meter each normalized and the normalized values of the respective respective parameters are set in proportion, whereby a ratio value is obtained for each parameter. The ratio value may then be processed to adapt the first building automation parameter in association with the class or classes of remote parameters of the at least one previous building.

It is expedient if, between each two buildings, a successor equation is formed from the ratio values of the parameters relating to the building and / or the building automation parameters and / or the building effects and / or the weather. Determining the successor relation, which is in advance, and particularly once performed before the implementation of it ^¬ inventive method, enables the targeted account certain predecessor building in ei ^¬ ner variety of potentially possible predecessor buildings. As a result, the method to be carried out for adapting the first building automation parameters can be accelerated.

A further advantageous embodiment provides that a time difference with which characterized by the currently erfass- th weather data at the location of at least one previous building on the site of the (to be controlled) buil ^¬ of arrives, is determined. Conveniently, the currently detected weather data of the building, the forecast for the location of the building weather, the detected Wetterda ^¬ th of the at least one predecessor building and the time difference determined to refined forecasted weather data for the location of the building to be processed.

Due to this design variant, it is possible to determine from the location of a predecessor building by measurement or prognosis. ed weather and knowing how long that there vorlie ^¬ constricting weather to reach the location of the controlled building needs to be used for the adaptation of the first building automation ^¬ sierungsparameter. In particular, local features which influence the weather on the way to the location of the building and which are taken into account by one or more scaling factors can be taken into account in the processing of the weather data. Also to be taken into account with the help of the scaling factors daily seasonal effects on the weather to reach the location of the re ^¬ gelnden building.

Another expedient embodiment provides that the adaptation of the first building automation parameters takes place based on the effects of the at least one predecessor building and of the building normalized by the ratio value.

The invention also proposes a computer program product that can be loaded directly into the internal memory of a digital computer and comprises software code sections with which the described steps of the process herein be ^¬ performs, when the product is run on a computer. The computer program product may be in the form of a CD-ROM, egg ^¬ ner DVD, a USB memory stick or via a network wirelessly or by wire fraught loadable signal.

Further embodiments and advantages of the invention are described below with reference to the drawings erläu ^¬ tert. Show it:

Fig. 1 is a schematic representation of different over

Localities distributed buildings; and

2 shows a schematic representation of a part number of the buildings shown in FIG. 1, the parameters of which are determined locally for the adaptation of building automation parameters of a building to be controlled. Fig. 1 shows a schematic representation of a plurality of geographically distributed buildings Gi, Gio · In the schemati ^¬ rule representation are exemplary ten building Gi, Gio illustrated, wherein for carrying out the following beschrie ^¬ surrounded method generally more or less, but at least two building can be considered. Under a geographical distribution of building Gi Gio means a ört ^¬ Liche distribution in different directions, with the building Gi Gio can be distributed in a country where several ^¬ ren countries in a climate zone or in several climatic zones and the like.

The buildings Gi, Gio, it may be the same or un ^¬ terschiedliche types of buildings, such as office buildings, producti ^¬ onsgebäude, warehouses or other buildings. The Ge ^¬ buildings Gi, Gio can have the same or different expansion with respect to their base surfaces, floor surfaces and the like. You can choose a similar roof shape (gable roof, flat roof, etc.) or a different one

Have roof shape. Similarly, the building materials used to make the buildings Gi, Gio may be formed of the same or different materials. For example, one or more of the buildings may be formed of bricks, while other buildings may comprise a concrete structure with glass façade elements. According to the building materials used, the buildings Gi, Gio have different heat transfer coefficients of their walls, windows and their roof.

In the method described below for the building to Gi (also known as: to be controlled building referred to) a Ge ^¬ bäudeautomatisierung with building automation parameters GAP _G i can be determined. Generally any Ge ^¬ buildings Gi Gi of buildings, Gio could be the object to be controlled building.

As to be controlled building the building Gi has an on ^¬ number of sensors with which (the state of the building temperature- (open eg blind (s) closed, opening degree and the like) temperature of one or more rooms, the state of sun protection devices, the state of the doors (geöff ^¬ net or closed), the state of windows (closed open window sash, the window sash tilted) Energiever ^¬ custom a heating system and / or air conditioning, Tem peratursollvorgaben for a desired room temperature, and the like can be detected in detail. The values recorded by the sensors are used to determine building automation parameters GAP _G1 .

In addition to the sensory acquired data, building data G _G i of the building Gi are taken into account in order to determine the building automation parameters GAP _G1 static, ie non-variable, and therefore only to be determined once. The building ^¬ data G _G i include a number of parameters, which the Ge ^¬ buildings Gi for example, by describing one or more of the following parameters: the its size, Wärmedurchgangskoeffi ^¬ coefficients, the surfaces of outer walls, windows, roof and Kel ler, Insulation quality of exterior walls, windows and roof.

In addition, weather ^{parameters of} current weather data W _G1 for the location of the building Gi to be controlled enter into the determination of the building automation parameters GAP _{G1 of} the building G to be controlled. The current weather data include weather information sensed at a given time or provided by, for example, weather services. The weather data can also encompass the future prognostic ^¬ ed weather information.

Since the building automation of the controlled building Gi as (open or closed) loop operates _G1 to be controlled in addition to the static building data G _G i and the permanent he ^¬ summarized weather data as further parameters currently valid and events in the past building automation ^¬ parameter GAP of Building Gi processed. He ^¬ result of building automation with building automation parameters determined CAP _G1 are mentioned in the above Parameters and the current environmental conditions resulting building effects, which include in particular as a parameter, a necessary or used energy to achieve a desirable ^¬ worth state of the building to be controlled.

The prediction of the necessary or energy used is especially dependent so ^¬ of the static building data G _G i as the current weather data W _G1 of the building Gi and the weather forecast for the future locally. The accuracy of the nose Prog ^¬ then required or consumed energy is thus dependent on the accuracy of the weather data W _G1 and the quality of an optimization procedure used to Be ^¬ humor building automation parameters GAP _G1.

To _G1 of the controlled building Gi to determine the building automation parameters GAP with respect to a minimal energy consumption (optimize) are be ^¬ taken into account in accordance with the proposed inventive method not only the above-mentioned local parameters for the object to be controlled building Gi, but also removed parameter at least used another building. These buildings are described in the present description as a predecessor building G _j ^¬ , wherein the index j in the method considered predecessor building from the total number of exemplary available buildings G ₂ , Gio includes.

It is also out ^¬ addressed for each of the building G _2, Gio that they have a building automation and thus, using sensors to detect the status of the building. Thus, for each of the buildings Gi, Gio also a number of parameters, but for different ^¬ locations, determined.

The total number of parameters determined for the building Gi and each predecessor building G is divided into four different classes. A first class G _Gx comprises the parameters PG1, PGn of static building data for a respective building G _x (where x = 1 to 10 according to FIG. 1). The second class of G _Gx Parame ^¬ tern includes the current weather information PW1, PWP for the location of the respective building G _x. Rametern A third class G _Gx Pa ^¬ comprises building automation parameters GAP _Gx of the respective building G _x. The fourth class G _Gx of parameters includes building effects PE1, PEo generated by the building automation parameter GAP _Gx . The suffixes n, m, o, p are each natural, positive numbers indicating the per ^¬ stays awhile number of parameters per class.

The first class G _Gx of parameters comprises, for example egg ^¬ NEN or more of the following parameters:

- a type of the building (eg office buildings, Produktionsgebäu ^¬ de, storage buildings, etc.);

- an intended use of the building (office building with Greater ^¬ offices, office building with small offices, production facilities for heavy engineering, mechanical engineering, electrical products, bearings for products to be cooled, warehouse for other products, etc.);

- a location of the building, expressed by the Konti ^¬ nent and / or the country in which the building G _x befin ^¬ det, and / or a latitude and longitude and / or a climate zone in which the building is located;

an orientation of the respective building G _x with respect to a cardinal direction (in order to be able to determine the areas irradiated by the sun during the day as well as solar profits);

- Surfaces of external walls and / or roof and / or basement, possibly divided according to the direction of the sky;

- materials of which the building G _x is set up to determine Were ^¬ megewinne and heat losses; and

The second class W _Gx of parameters includes current weather ^¬ data for the location of the building under consideration G _x, in particular a temperature, a humidity, a sun, a sun, a cloud cover, rain, rainfall, etc. The third class GAP _Gx of parameters includes Regelungspara ^¬ meter of the housing, such as setpoint data for a heating or air conditioning control data for shading devices, a setpoint for humidity, etc. In addition, the third class GAP _Gx of each housing includes as parameter energy consumption _data of the building. The building automation parameters are detected in particular over time.

The fourth class E _Gx of parameters includes parameters bezüg- lent a necessary or consumed energy input to achieve a desired state of each to be controlled by means of Gebäudeau ^¬ tomation building G _x.

Since the determination of building automation parameters GAP _G1 of the controlled building Gi is performed using a Optimierungsver ^¬ driving, is expediently provided, not all the parameters of all predecessor building G _2, Gio to be ^¬ into account but only the totality of the parameters of such predecessor building G _j, which a certain similarity of having to be controlled to the building in terms of their Gi stati ^¬ rule building data and relating to the weather data. For this purpose, similar or comparable buildings are first found to the building G to be controlled, in relation to one or more of the following criteria:

- a geographical location, in particular a latitude.

A similarity exists if the latitude of the previous building is within a given bandwidth, e.g. ± 30 angular minutes (corresponding to the traditional sagesimalsystem) around the latitude of the building Gi to be controlled;

- the country, since then a similar user behavior or user perception, eg due to national regulations or laws, can be assumed; - a building type;

- a building orientation.

In the present embodiment, it is assumed that a similarity between the building to be controlled Gi and the building G6 is present, since these lie on a vergleichba ^¬ ren latitude in west-east direction and has comparable average weather conditions. Average weather conditions may be detected based histori ^¬ shear, concrete weather observations and compared. For example, ^¬ stands a sunlight this at predetermined Zeitab, a concrete

Cloud shading, a specific wind force, a certain temperature, a certain amount of precipitation recorded, are statistically evaluated and compared over time. Benchmarks, for example, similar average ^¬ temperatures, similar amounts of moisture, similar wind speeds, the same wind direction, a similar sunshine hours and its precipitation. In addition, it is assumed in this embodiment that the buildings Gi and G6 are in the same country, suggesting moving ^¬ che usage conditions. Building type and building ^orientation can be the same or different.

In the further description, reference will now be made only to the two buildings Gi and G6, which are shown highlighted with their four classes of parameters in Fig. 2. The method described below may be repeated for other pairs between the building to be controlled to Gi ei ^¬ nem other predecessor building G _j in the same manner as ^¬.

For the building Gi to be controlled and the predecessor building G6, scaling factors between the respective classes of the local parameters for the location of the building Gi and the corresponding classes of the remote parameters for the predecessor building G6 are now determined. For this purpose, a respective local Parameters, eg PGl the first class G _G i of the building Gi with the corresponding parameter PGl the first class G _G 6 of the predecessor building G6, normalized, the normalized ^¬ th values of each corresponding parameters are set in a ratio to obtain a ratio value for each parameter. Includes, for example, the object to be controlled building Gi is an area of 1,000 square meters, while the area of the building G6 is only 500 square meters, as the ratio value of ^¬ for the parameter PGI (1000 sqm / 500 sq = 2. If the duration of sunshine at the building G6, for example, expressed as the parameter PW1 of the second class W _G6 ) = 8h, while the sunshine duration of the building Gi to be controlled is only 7.5h, the ratio is 7.5h / 8h = 0.9375.

This procedure is repeated for all parameters of all classes of parameters. In addition, a temporal difference with the arrives that characterized by the currently detected Wetterda ^¬ th weather at the site of the previous building G6 in the place of the building Gi determined. Because ei ^¬ ner exemplary distance of 200 km between the further west in the building G6 and the building to be controlled Gi is a time shift of two hours yields, for example. In addition, different times of sun rise and fall as well as the time of acquisition of the parameters can be taken into account.

As a result, a relative comparison between the differences between the building Gi to be controlled and the predecessor building G6 can be determined as a result. It can be in a first

It can be assumed that there is only one relative comparative value for all the parameters of the four classes. In a second version, there can be a corresponding comparison value for each parameter of each of the four classes. In a third form, these comparison values may also depend on the time (time of day or season). This information is subsequently used to describe the building automation parameters To adapt GAP _G1 of the controlled building Gi using the parameters determined from the pre ^¬ predecessor building G6 detected or for the predecessor building G6.

The method for computer-aided determining of building automation parameters GAP _G1 of the controlled building Gi is effected in particular iteratively by first building ^¬ automation parameters GAP _G1 of the building Gi based on the first class G _G i of static building data of the re ^¬ gelnden building Gi, the second Class W _G1 of current weather data for the location of the building to be controlled Gi and the third class GAP _G1 of current and / or lying in the past building automation parameters of the regulated building Gi are determined. In addition, parameters of the optimization method used and a starting value of the optimization method are used.

Subsequently, an adaptation of the resultant from the Opti ^¬ mierungsverfahren first building automation parameters GAP _G1 by changing the parameters of the weather data W _G1 with the weather data of the predecessor building W be improved _G6. Optionally, the parameters of the building data G _G 6 of the previous building G6 are taken into account in consideration of the advance he ^¬ mediated scaling factors in addition.

The quality of the building automation ^parameter GAP _{G1 of} the building Gi to be controlled with the aim of minimum energy consumption can be further improved if the starting value of the optimization method not only the parameters of the building automation parameters GAP _G1 , but also the building automation parameters GAP _{G6 of} the previous building G considered at the time the ^¬, which lies to the pre-determined time step in the past. Again, the previously determined scaling factor is used.

Finally, there is a further improvement in that, in addition, the building effects E _{G1 of} the regulatory regime building G and E _{G6 of} the predecessor building G, using the previously taken into account scaling factors. The processing is performed such that the Ge ^¬ bäudeeffekte E _G6 of the previous building G6 are taken into account at the time in the past that to reach the place of the controlled building Gi be compels ^¬ the weather.

The realization can be done by extrapolation of the parameters of the predecessor building Gi or by the use of

Covariance matrices are implemented if certain Para ^¬ meter be affected by other parameters of the G6 predecessor building (for example, the state of the blinds position influenced by the interior illumination).

As a result, the findings from existing sensory or by simulation / calculation determined data of a previous building, which is in a similar time zone as the object to be controlled buildings used by the predecessor building on the previous prevailing weather and the fact is he ^¬ giving building automation parameters for the building to be controlled are extrapolated into the future. In particular, a predictive calculation of Gebäudeautomatisie ^¬ approximately parameter is possible.

Thus, for example, if strong sunlight is to be expected in the building to be controlled for the future, predictively the air conditioning will be controlled so that it has already caused the arrival of strong sunlight in advance lowering the room temperature. In the opposite case, if for example, a rain front in which can be expected to re ^¬ gelnden building due to the currently recorded in the previous building weather in the future, the Air ^¬ plant control predictive reduced and possibly a Heizvor- direction are activated.

In this way an increased efficiency in the Au ^¬ tomation of the controlled building is possible on the one hand, on the other hand the well-being of users of the building can be increased by predictive control.
