PD CEN/TR 16946-2:2016CEN/TR 16946-2:2016 (E) 4 Introduction The CENSE project, the discussion between CEN and the Concerted action highlighted the high page count of the entire package due to a lot of “text

17、book” information. This resulted in flooding and confusing the normative text. A huge amount of informative contents shall indeed be recorded and available for users to properly understand, apply and nationally adapt the EPB standards. The detailed technical rules CEN/TS 16629 ask for a clear separa

18、tion between normative and informative 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 technic

19、al report, like this one, where all informative content is collected. Table 1 shows the relative position of this standard within the EN EPB set of standards.

BAC performance has a tendency to decline over time if not actively checked, maintained and adapted to the actual use of the

31、 building (independent of the building type). This performance depends on a number of factors. Some of the factors are: building / space usage changes equipment maintenance and re-commissioning manual interventions and missing “back to “normal” change manual set point adjustments and back to “normal

32、” procedure This technical recommendation describes a methodology to audit “BAC” in any state of its implementation in a building. PD CEN/TR 16946-2:2016CEN/TR 16946-2:2016 (E) 7 An inspection shall: hold all important data for a specific BAC keep track of the inspected BAC portion and its model dat

34、ent colours are to separate the various flows. Heating: red; cooling: blue; air flow: yellow Figure 1 Principle functions being addressed in prEN 15232-1:2015 4.2.2 Explanation of graphic Energy flow is indicated by lines whereas equipment and its control logic is represented by boxes. The numbers a

35、re referring to the (controls) functional groups in prEN 16946-1:2015, Table 1. Identifying the energy flows in the technical systems is important because efficient functions deliver audit result contributions among the entire energy flow of that particular instance. The colours indicate the various

36、 energy carrier types (e.g. warm water, cold water, air). The graphic might imply that all systems shall be present to perform an audit. This is not the case, Systems are audited according to their existence and functions implemented whereas non existing equipment does not need to be mentioned. Logi

37、c shall identify non-existing equipment and exclude it from the evaluation while applying a correct weighting. PD CEN/TR 16946-2:2016CEN/TR 16946-2:2016 (E) 8 4.3 Functionality Description The functionality of BAC is described in prCEN ISO/TR 52000-2:2014. The generic terms shall be applied as most

38、appropriate since the description is kept at high level to be technology independent. 4.4 Implementation of Inspection Procedures 4.5 Scope The scope of the audit includes controls functions for: Generation of heating and cooling Ventilation Lighting Blinds (Sunlight protection) Domestic Hot Water T

39、echnical Building Management Other systems as defined in the implementation guidelines 5 Classification Method 5.1 Purpose of Classification The main purpose of the classification is to establish a relationship between a set of functions and the capability of energy efficiency for the installed and

40、working BAC functions with its weighted influence. 5.2 Classification using Points A classification that applies the efficiency classes according to the EN Standard would not necessarily allow differentiating the result in a way to use it for e.g. improvement recommendations. A simple method to stre

41、tch the result among e.g. a normalized scale from 0 to 100 shall serve the purpose. Other scales might apply accordingly. In this document the scale of 0 to 100 shall be used as example. Interpreting an audit result using the scale would give a simple analysis method: More points lead to a better ef

42、ficiency of the BAC analysed. 5.3 Classification influence factors The document prEN 16946-1:2015 implies a number of influence factors that need to take into account while assessing a BAC. The factors are: Building type (e.g. office building) Weighting factors of the services among the building ser

43、vices Applicable space regarding e.g. emission functions Energy generation and supply functions supplying above space Desired usage time of above space Schedules of equipment PD CEN/TR 16946-2:2016CEN/TR 16946-2:2016 (E) 9 5.4 EN 15232 Classes The standard assigns efficiency classes per functional g

44、roup in its associated TR. It might be useful depending on the implementation of a specific classification system to determine the EN 15232 classes as well however this can only be done on a per functional group basis. With a complex mix of functionality within the same application a weighted points

45、 value is calculated. The points relate back to EN 15232 functions and are converted to A/B/C/D. This is calculated in such a way that to reach an A, the point score shall be larger than the average of points for A and B, i.e. higher than 2,5, to reach a B it shall be higher than 1,5, etc. According

46、 to the rules of EN 15232 to achieve an A, all applications (groups of functions), e.g. 1.1, 1.2, 1.3 etc., shall be A. So the worst scoring group of functions decides the final classification according to A/B/C/D. However there are some rules included in EN 15232:2012 that allow for missing functio

47、nality and functionality that has no substantial impact (5 %) within the kind of energy used for Heating, Cooling, Ventilation, DHW, Lighting or Blinds. These rules are taken into consideration when calculating the final assessment results. PD CEN/TR 16946-2:2016CEN/TR 16946-2:2016 (E) 10 Annex A (i

48、nformative) Example of an inspection system (available through eu.bac.org) A.1 Introduction The check-list is a Microsoft Excel document to be used by inspectors when performing an audit in a building. The latest version is available from the eu.bac website: system.eubac.org. The document is organiz

49、ed in several sheets in separate tabs: The first SUMMARY tab is used to record basic building information and to present the summary result. It is also where the exception rule of EN 15232 (5 %) may be input. Six tabs are used for the main recording of information from the Building Automation and Control System: Rooms, AHUs, Heating, Cooling, DHW and TBM. The Notes tab should be used to record observations and motivations for specific selections mad
