This resulted in flooding and conf

The detailed technical rules CEN/TS 16629 Detailed Technical Rules ask for a clear separation between normative and i

16、nformative contents: to avoid flooding and confusing the actual normative part with informative content; to reduce the page count of the actual standard; to facilitate understanding of the package. Therefore each EPB standard shall be accompanied by an informative technical report, like this one, wh

30、 to obtain this goal - which shall be minimal! The scope of BAC and TBM covers in accordance with their role from one side all Technical Building Systems (where the effect of the BAC is used in the calculation procedures) and from another side the global optimization of the energy performance of a b

31、uilding. PD CEN/TR 16947-2:2016CEN/TR 16947-2:2016 (E) 7 We could identify several categories of controls: Technical building systems specific controls; these controllers are dedicated to the physical chain of transformation of the energy, from generation, to storage, distribution and emission. We f

32、ind them in the matrix starting with the modules M3-5 to M9-5 and finishing with M3-8 till M9-8. We could consider that it exist one controller by module, but some time one controller do the control among several modules. More often, these controllers are communicating between them via a standardize

33、d open bus, such as BACnet, KNX or LON BAC used for all or several technical building systems who do multidiscipline (heating, cooling, ventilation, DHW, lighting) optimization and complex control functions. For example, one of them is INTERLOCK, a control function who avoids heating and cooling in

34、same time. If all Technical Building System are used in the building, we have (depending of the size of the building) a Technical Building Management System. Specific global functions are implemented here, necessary to reach the key-role mentioned above. Usually, in this case, an interrelation with

35、the building as such (Module M2) will occur, mainly to take in consideration the building needs; for example due to outside temperature, taken into account the inertia of the building when the control will reach the set point in a room. In a control system dedicated to a building, who is BAC and TBM

36、 we can distinguish three main characteristics: Control Accuracy, Control Function, Control Strategy. Technical Building management systems are implemented to realize an overall building operation strategy by interdisciplinary orchestration of building energy systems (heating, cooling, ventilation,

37、lighting) whereas systems are controlled by BAC functions. Further information about control accuracy and control functions can be found in the technical report CEN/TR 15232-2. EN 15232 describes two approaches how to evaluate the contribution of building automation and control on the energy perform

38、ance of buildings. This Technical report is dedicated to control strategy and Technical building management issues covered by EN 16947-1. PD CEN/TR 16947-2:2016CEN/TR 16947-2:2016 (E) 8 5.2 Control Strategy The Control Strategy is applied to achieve a given level of control to reach a goal. Optimal

39、control strategies deliver a desired level of control at a minimum cost. A Control Strategy could consist by a Control Function or a group of Control Functions. An example of a Control Strategy consist by a Control Function is Optimum Start, Optimum Stop, Night Set Back described in the standards EN

40、 12098-1 and EN 12098-3. The Timer function is described in EN 12098-5. An example of a Control Strategy who is realized by a group of Control Functions is the Control Strategy used by Intermittence. This function uses several Control Functions, Operation Modes, Optimum Start- Stop and Timer in same

41、 time. All elements together are called either Building Profile or User Pattern. Usually, to implement such Building profile, a TBM is a prerequisite. The most important Control Strategy described and implemented in EN 15232-1 is Demand Oriented Control. Usually these strategies implement the sense

42、of the energy flow (from GENERATION to EMISSION) with flow of calculation (from building needs to delivered energy). Usually for this complex Control Strategy, a TBM is necessary with a distributed specific control for each Technical Building System who communicates in system architecture via a comm

43、unication standardized bus such as BACnet, KNX or LON. More clear, this Demand Oriented Control works as follows: When the comfort is reach in the Emission area, the controller from the Emission sent the message to the controller in charge of Distribution to stop to distribute energy, who sent the m

44、essage to the controller in charge of Storage either to store the energy and if the Storage cannot store more energy sent the message to the controller in charge with the Generation to stop to generate more energy. Another important Control Strategy is the control strategy for multi generators eithe

45、r from same type (e.g. several boilers) or different types (e.g. a boiler and heat pomp) including also the Renewable Energy Sources. This strategy is described in more detail in the Sequencing of multiple generators (BMS function 3) chapter later on. The standards enabling to calculate the effect o

46、f BACS and TBM functions on energy consumption use different approaches to calculate this impact. 5.3 Rationale This method is meant for a detailed energy performance analysis of a building in case detailed information about the building, the HVAC system and especially the type of automation, contro

47、l and management functions is available that can be applied in a holistic EPB calculation method. The method should be used only when a sufficient knowledge about automation, control and management functions used for the building and the energy systems is available. The application of the calculatio

48、n procedures implies that all automation, control and management functions that have to be accounted for the operation of a building and its energy systems are known.

49、ly; hourly; or the statistical BIN method can be applied. Beside Bin method this is according to the time-step of the input. Normally it is designed for a monthly or hourly method. 5.4.2 Assumption It is assumed that a calculation method is available that can be used to quantify the impact of Technical building management and building automation and control on the energy performance of a building. The EPBD holistic approach is an appropriate calculation method. 5.4.3 Data input Item 1 Beside all technical i
