TO ALL NATIONAL COMMITTEES TO ALL TECHNICAL COMMITTEES AND SUBCOMMITTEES

Draft IEC Guide 119 Edition 1, Preparation of energy efficiency publications and use of basic energy efficiency publications and group energy efficiency publications

Dear Sir/Madam, The SMB approved by SMB Decision 149/9 a request from the Advisory Committee on Energy Efficiency (ACEE) to develop a new IEC Guide with a focus on the organizational issues related to energy efficiency in IEC. The work took place under the leadership of two of the ACEE members, assisted by some other ACEE experts. Further information on this work is attached at Annex 1. The latest draft of IEC Guide 119 Edition 1 is herewith circulated for comments following the reports previously submitted by ACEE to the SMB. IEC national committees, technical committees and subcommittees are invited to review the draft attached, and send their comments to the ACEE secretariat, dle@iec.ch, using the latest IEC form for comments,

by 2016-03-04 at the latest, so that their comments can be considered by ACEE.

Yours faithfully, F.W.P. Vreeswijk General Secretary & CEO Annex 1: Background information on the development of IEC Guide 119 Edition 1 by ACEE Annex 2: Draft IEC Guide 119 Edition 1 DLE

Annex 1 Background information on the development of IEC Guide 119 Edition 1 by ACEE

The original request was made by the ACEE in its report to the SMB in document SMB/5173/R. ACEE Recommendation 1310/1:

Deliverables

1. Future IEC guide with a focus on the definition of energy efficiency aspects and on the derivation of general methodologies for energy efficiency publications complemented by a survey of existing IEC work on energy efficiency.

2. Future IEC guide with a focus on the organizational issues related to energy efficiency in IEC.

Work Structure 1. Task team 1 – Definition of energy efficiency aspects 2. Study group 1 – Overview of existing energy efficiency publications 3. Task team 2 – Description of energy efficiency organization in IEC.

NOTE Task team 2 consist of the following members: L. Boutin (Co-convenor, representing CA NC), P. Zwanziger (Co-convenor, TC 22), R. Sporer (ACEE Chair), F. Bua (IT NC), T. Ishikuma (JP NC), J.Y Choi (KR NC), D. Manole (US NC), J. Peronnet (TC 64), H. Hayashi (TC 120), K. Hiereth (TC 121) The above recommendation was approved according to SMB Decision 149/9: SMB Decision 149/9 – ACEE Report – SMB/5173/R, SMB 5173A/RV The SMB noted the report from ACEE and approved its work programme, notably the development of two guides, one on energy efficiency aspects and methodologies, and the other on organization issues related to energy efficiency in IEC.

Since inception of the task team, L. Boutin together with P. Zwanziger produced four working drafts prior to the draft attached; they were circulated for comments within the task team and subsequently discussed via web conferences and at ACEE meetings. After its meeting on 2015-09 ACEE communicated the following to the SMB (see document SMB/5705/R). B.1 Future ACEE deliverable – Work progress of task teams and study group The two draft guides for the two task teams are progressing. The comments received on the drafts were discussed through web conferences as well as during the meeting. Having discussed the comments and the agreed way to handle them, the meeting concluded that the two draft guides are ready for the CD stage and they will be submitted in early 2016. This should be in line with the SMB approved date of publication in late 2017 or early 2018. The progress of work in study group 1 reported that it had analyzed a total of 339 publications which may be in relation to energy efficiency. The next step is to identify a way to classify these publications towards energy efficiency aspects. A proposal to achieve this is expected at the next ACEE meeting in April 2016.

FOREWORD 65

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising 66 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote 67 international co-operation on all questions concerning standardization in the electrical and electronic fields. To 68 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, 69 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC 70 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested 71 in the subject dealt with may participate in this preparatory work. International, governmental and non-72 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely 73 with the International Organization for Standardization (ISO) in accordance with conditions determined by 74 agreement between the two organizations. 75

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international 76 consensus of opinion on the relevant subjects since each technical committee has representation from all 77 interested IEC National Committees. 78

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National 79 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC 80 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any 81 misinterpretation by any end user. 82

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications 83 transparently to the maximum extent possible in their national and regional publications. Any divergence 84 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in 85 the latter. 86

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity 87 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any 88 services carried out by independent certification bodies. 89

6) All users should ensure that they have the latest edition of this publication. 90

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and 91 members of its technical committees and IEC National Committees for any personal injury, property damage or 92 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and 93 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC 94 Publications. 95

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is 96 indispensable for the correct application of this publication. 97

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of 98 patent rights. IEC shall not be held responsible for identifying any or all such patent rights. 99

This first edition of IEC Guide 119 has been prepared, in accordance with ISO/IEC Directives, 100 Part 1, Annex A, by the IEC Advisory Committee on Energy Efficiency (ACEE). This guide 101 is a non-mandatory guide in accordance with SMB Decision 136/8. 102

3.6 175 group EE function 176 task assigned to a TC to prepare group EE publications 177

4 Systems approach 178

4.1 General considerations 179

Energy efficiency is a requirement for products, systems and organizations. EE measures 180 shall not compromise safety nor affect the level of services. EE should be in balance to 181 economic and market constraints. EE of a product should be in balance to the depletion or 182 voiding of environmental resources that have been used to produce it. It may not be sufficient 183 to improve the energy efficiency of a single product without considering its application. 184

Conversely it is generally acceptable to decrease the energy efficiency of a single product 185 when this is off-set by an overall improvement of energy efficiency when considering its 186 environment and application. As an example the lower EE of power factor corrected a.c. to d.c. 187 converter is off-set by decreasing the losses in the a.c. network supplying the converter. This 188 clause explains how technical committees should consider the systems approach in their work 189 where several TCs have to collaborate. This guide proposes a way of collaboration between 190 TCs on the bases of the boundaries between their respective responsibilities. 191

The main part of this approach is a standardized description of this boundary which defines 192 the object of energy efficiency evaluation and improvement as well as the interfaces between 193 the TCs. 194

NOTE: The description of the boundary (physical or conceptual) should include information about the service(s) 195 that are to be provided. This description will make no assumptions about physical implementation needed to realize 196 the service(s). Examples of services are e.g. providing steam, producing metallic parts, converting heat. 197

IEC GUIDE 119 © IEC 2015 – 9 –

4.2 Boundary description 198

The boundary description should be understood by each TCs. 199

4.2.1 General 200

Boundaries should be defined in terms of: 201

• intended use (relevant applications); 202

• energy inputs; 203

• outputs; 204

• driving parameters other than internal process parameters (relevant variables, static 205 factors); 206

• KPIs (energy efficiency indicators); 207

• interactions between components of the system; 208

• possible interactions with other systems. 209

Boundaries can include a device, a product or a system depending on the application 210 considered. 211

NOTE In the case of a physical product boundaries may be: 212

• the physical limits of the product, 213

• power inlets or outlets, 214

• communication interfaces, 215

• media inlets or media outlets. 216

Functional boundaries (e.g. in the case of a service) may be: 217

• the starting of a specification, 218

• the conclusion of a specification, 219

• the defined transfer of information, of material, or of other services” 220

4.2.2 Elements of the boundary description 221

222

Figure 1 – Boundary description and its elements 223

– 10 – IEC GUIDE119 © IEC 2015

The boundary description may include a list of services (conceptual boundary) or a list of the 224 technical elements and their relation (technical implementation) that are within the chosen 225 boundary. The further elements of the boundary description are the following: 226

4.2.3 Input(s) 227

The boundary description has input(s) necessary to perform the intended service, which can 228 be defined by the following elements: 229

• type of input, 230

• quality of input, 231

• quantity of input 232

Examples are materials, parts, electrical energy, operational expenditures and information. 233

4.2.4 Output(s) 234

The boundary description has output(s) as result(s) of the intended service which can be 235 defined by the following elements: 236

• type of output, 237

• quality of output, 238

• quantity of output 239

Examples are products, reusable material, reusable energy, waste and information. 240

4.2.5 Driving parameters 241

The driving parameters should be defined. These are all external factors that affect energy 242 efficiency and include, for example: regulation, environmental conditions, energy prices and 243 management requirements. Mode of operation, duty cycle, load curves, state, operating 244 parameters indoor temperature, lighting levels, production volume, range of products, etc. 245

NOTE Driving parameters concept includes the concept of relevant variable and static factors as defined 246 respectively by ISO 50002 and ISO 50006. 247

4.2.6 Energy efficiency related KPI(s) 248

The key performance indicators (KPI) such as defined in ISO/lEC Guide 118 must be provided. 249 All KPIs related to energy efficiency will be dependent on the boundary description (see 250 examples in Annex A). 251

4.3 Broader boundary description – systems approach 252

Elements of the broader boundary description are shown in Figure 2. 253

IEC GUIDE 119 © IEC 2015 – 11 –

254

Figure 2 – Broader boundary description 255

The choice of the boundary is central for the possible EE improvements. The energy 256 efficiency of a complex system needs to be analysed using a systems approach instead by 257 seeking to optimize the performances of each single component. This means that it is 258 advisable to consider wider boundary descriptions including several services and components 259 in order to provide more systemic improvements. An example of this approach is shown in 260 Figure A.3. 261

In these cases several technical committees will need to collaborate in order to sufficiently 262 deal with the product (incl. systems, processes) under consideration. Ideally this includes all 263 technical committees which deal with significant energy use components that are part of the 264 boundary description. Together the committees need to develop the individual boundary 265 descriptions of all elements of the wider boundary description. This includes the services and 266 elements, inputs, outputs and boundary conditions to perform the intended service. All inputs 267 and outputs, including energy loss, and the boundary conditions of the individual boundary 268 descriptions inside the wider boundary description are also important to be exchanged so that 269 systematic solution can be assessed. 270

The boundary will also give an indication whether a single TC is able to deal with analysing 271 the boundary themselves or whether collaboration with other TCs is necessary. 272

Annex B describes the systems approach as a collaborative example. Whenever a group of 273 TCs is necessary to develop a boundary description this should be done in a group EE 274 publication. 275

If an individual TC is able to develop a boundary description for the product under 276 consideration by them, this can be done in a product publication. 277

5 Assignment of horizontal energy efficiency functions and of group EE 278 functions 279

The assignment of horizontal EE functions and group EE functions is the responsibility of the 280 Advisory Committee on Energy Efficiency (ACEE), subject to confirmation by the SMB 281 (Standardization Management Board). Assignments are periodically reviewed by ACEE. For 282 the structure of IEC EE publications and function assignment, see Figure 3. 283

284

Figure 3 – Structure of IEC EE publications and function assignment 285

The assignment of a horizontal EE function or group EE function to a technical committee is 286 made with the purpose of: 287

• ensuring the consistency of IEC publications relating to EEA common to a number of 288 technical committees by avoiding duplication of work and contradictory requirements; 289

• reducing the size of IEC publications by avoiding duplication of texts; 290

• improving mutual understanding among engineers of different technical disciplines. 291

A horizontal EE function or a group EE publication may be assigned to a TC for the whole or 292 for a specific part of its activities. Annex B describes the extended product approach as a 293 collaborative example. 294

The IEC Catalogue 295 (http://webstore.iec.ch/Webstore/webstore.nsf/0/81CDC3DD7D40BFC5C1257C0600378CBA? 296 OpenDocument#) 297 and website 298 (http://www.iec.ch/dyn/www/f?p=103:59:0::::FSP_ORG_ID,FSP_LANG_ID:3228,25#2 ) shall 299 provide a method for identifying basic EE publications and group EE publications. 300

6 Energy efficiency publications 301

6.1 General 302

6.1.1 Basic EE publications and group EE publications 303

6.1.1.1 General 304

It is recommended to consult IEC Guide 118 when producing EE publications. 305

IEC GUIDE 119 © IEC 2015 – 13 –

Basic and group EE publications shall contain aspects relevant to the horizontal or group EE 306 function and shall be written in a manner understandable by product TCs. General and 307 horizontal requirements, methodologies, measurement, benchmarking, KPI calculations etc. 308 must be defined in a general way applicable to all TCs in the area. 309

6.1.1.2 Basic EE publications 310

The general EEA should be listed in basic EE publications and are described in Guide 118. 311

Basic EE publications should explain the principles on which they are based in order to assist 312 product TCs. Guidance shall be given to product TCs on how to apply information from a 313 basic EE publication. Standardized methods for representing common characteristics which is 314 used for evaluation and improvement of overall energy efficiency could be an example of 315 basic EE publication. 316

The focus of basic EE publications is the general tools and agreed methods for describing or 317 achieving EE improvement in a defined boundary. These publications will therefore describe 318 EEA like measurement, calculation and further methods like benchmarking, KPI calculation for 319 EE as described in IEC Guide 118 Guide. 320

A basic EE publication should include in its scope the essence of the text given below: 321

"This basic EE publication is primarily intended for use by technical Committees in the 322 preparation of standards in accordance with the principles laid down in IEC Guide 119 and 323 IEC Guide 118. It is not intended for use by manufacturers or certification bodies." 324

One of the responsibilities of a technical committee is, wherever applicable, to make use of 325 basic EE publications in the preparation of its publications. The publications should define the 326 EE aspects which apply for the whole of IEC work for EE e.g. test methods, conditions, 327 measurement, conformity assessment, definition of system boundaries, load profile, key 328 performance indicator, etc. 329

In a few cases, a basic EE publication can, in addition, be intended for use as a standalone 330 publication. In such cases, the first paragraph shall be modified accordingly. 331

A basic EE publication shall include IEC Guide 119 and IEC Guide 118 in its list of normative 332 references. 333

It is essential that basic EE publication not be frequently amended or frequently revised; 334 because product TCs need to be given time to align their publications with the current edition. 335

6.1.1.3 Group EE publications 336

Group EE publications may be primarily intended as EE publications, but should also be used 337 by other product TCs in applying their provisions. In addition, guidance should be given to 338 product TCs on how to apply information from a group EE publication, for example, how to 339 define boundaries for a particular application (e.g. interrelation between light fixture, motion 340 detector, outside shading, etc.). 341

A group EE publication should include in its scope the essence of the text given below: 342

"This group EE publication is primarily intended to be used as a EE standard for the products 343 mentioned in the scope, but shall also be used by technical committees in the preparation of 344 standards for products similar to those mentioned in the scope of this standard, in accordance 345 with the principles laid down in IEC Guide 119 and IEC Guide 118." 346

A Group of EE publication shall include IEC Guide 119 and IEC Guide 118 in its list of 347 references. 348

– 14 – IEC GUIDE119 © IEC 2015

It is essential that group EE publications will not be frequently amended or frequently revised; 349 because product TCs must be given time to align their publications with the current edition. 350

6.2 Product publications 351

Energy efficiency aspects specific for an individual product in the scope of one TC are 352 described in product publications, especially providing information about boundary, input 353 (energy), output (service), additional information (e.g. mode of operation, duty cycle, state) 354 and KPIs in a standardized way. 355

A product publication related to EE should cover all relevant EE aspects of the products within 356 its scope. 357

NOTE IEC Guide118 contains a list of EE aspects. 358

Safety aspects and EE aspects should not be covered in the same publication, as this makes 359 it difficult to assess conformity with EE requirements alone. If there are reasons to cover them 360 in the same publication, EE aspects and the other aspects shall be clearly distinguished from 361 each other. If there are EE criteria which have safety implications, these are considered 362 safety aspects and shall be clear in the publication. 363

A product publication related to EE shall not include requirements which unnecessarily restrict 364 design or construction, or impede technical progress and development. Product should be 365 design in such way to facilitate the installation of additional EE components (e.g. 366 measurements, sensors, etc.). 367

6.3 References to other publications 368

Where possible, references to particular text shall be used instead of repeating the original 369 source material, since repetition increases the possibility of errors in quoting, and adds to the 370 length of publication. If it is not possible to avoid repetition of original material, its source shall 371 be identified. 372

7 Responsibilities of TCs with horizontal EE functions and group EE functions 373

7.1 Liaison with other TCs 374

Secretaries with a horizontal EE function or a group EE function shall inform Central office of 375 any new work item proposal (NP) relating to a basic EE publication or Group EE publication 376 and indicate as far as possible those TCs which may be affected. These TCs shall be listed 377 when circulated. 378

A TC with a horizontal EE function or a group EE function should respond to requests for 379 liaison from product TCs (see 8.1), and keep informed about the progress of relevant work. 380

7.2 Requests from product TCs for New Work 381

A TC with a group EE function should consider any request from a product TC (see 8.4) within 382 three months or longer if acceptable to the product TC. It may be necessary to handle such 383 requests by correspondence, if a plenary meeting of the TC with the EE function is not 384 scheduled for some time. 385

The TC with the EE function should inform the product TC whether or not it considers that the 386 proposals are appropriate and sufficiently general to be included in a basic EE publication or 387 a group EE publication. If they are considered to be appropriate, it should develop a further 388 basic EE publication or group EE publication, or amendments to an existing publication, in 389 close liaison with the product TC. 390

IEC GUIDE 119 © IEC 2015 – 15 –

If the proposals are not considered appropriate by the TC with the EE function, it should, in 391 close liaison with the relevant product TC, make an alternative proposal to cover the needs of 392 product TCs. Such proposals should not conflict with the basic principles explained in the 393 basic EE publication or group EE publication. 394

If, after consultation, agreement still cannot be reached between the TCs involved, the matter 395 shall be referred to ACEE with the necessary technical explanation. If the matter cannot be 396 resolved by ACEE, it will be referred to the Standardization Management Board for resolution. 397

8 Responsibilities of product TCs 398

8.1 General 399

Product TCs should determine which existing basic EE publications and group EE 400 publications are relevant to their work, and establish and maintain liaison with the TCs 401 responsible for preparing those publications. 402

Product TCs should indicate their interest in NPs relating to a basic EE publication or group 403 EE publication to the TC with the EE function and be encouraged to contribute to the 404 development of the NP by, for example, participating in working groups and submitting 405 comments on drafts. 406

8.2 Application of basic EE publications 407

Product TCs, when preparing, amending, or revising EE publications, should make use of any 408 relevant basic EE publications. They may select from such publications relevant requirements, 409 test methods and test conditions specific to their product area, but shall not modify them 410 except as specified in 8.4. 411

Where a product TC incorporates in its publication an amended version of a requirement, test 412 method or test condition of a basic EE publication, in accordance with 8.4, a note in the 413 foreword shall indicate the changes which have been made. In addition, there shall be 414 references to the foreword at the places where changes have been made. 415

If it is not practicable for a product TC to align an existing publication immediately with the 416 relevant requirements, test methods or test conditions of a new, amended or revised basic EE 417 publication, alignment should be carried out when the product publication is next amended or 418 revised. 419

8.3 Application of group EE publications 420

Product TCs when preparing, amending or revising any EE publication in a product area 421 falling within the scope of one or more of the group EE functions as listed in the IEC 422 Catalogue should make use of the relevant group EE publications. They may, after 423 consultation with the TC with the group EE function, modify requirements, test methods and 424 test conditions as appropriate for the products concerned. 425

If it is not practicable for a product TC to align an existing publication immediately with the 426 relevant requirements, test methods or test conditions of a new, amended or revised group 427 EE publication, alignment should be carried out when the product publication is next amended 428 or revised. 429

A practical example is shown in Annex B. 430

8.4 New work requests to TCs with EE functions 431

A product TC can have a need for requirements, test methods or test conditions falling within 432 a horizontal EE function or group EE function but which are not adequately covered in existing 433

– 16 – IEC GUIDE119 © IEC 2015

EE publications. In this case, the product TC shall submit proposals, including a date for 434 completion, for the development of a new basic EE publication or a group EE publication, or 435 for amendments to an existing publication. If appropriate, this can be in the form of an NP. 436

The proposals will be considered by the TC with a horizontal EE function or a group EE 437 function, as detailed in 7.2. 438

In some cases, a TC with a horizontal EE function or a group EE function may not accept a 439 proposal for new work or may accept it but be unable to offer completion by a date acceptable 440 to the product TC. In other cases, a product TC may not consider that the text provided by the 441 TC with a horizontal EE function or a group EE function is suitable for incorporation in its 442 publication. 443

In the above circumstances, the matter shall be referred to ACEE, who may authorize the 444 product TC to undertake the task itself. Relevant documents generated in the course of the 445 development of these requirements, test methods or test conditions, shall be sent to the TC 446 with the horizontal EE function or group EE function. 447

If relevant requirements, test methods or test conditions are later included in a basic EE 448 publication or a group EE publication, the product TC shall align its own publications with 449 them, as detailed in 8.1. 450

Annex A 451

(informative) 452

Boundary examples 453

One typical way of boundary definition is picking up an individual service clearly identified as 454 a significant energy user. For example, as shown in Figure A.1, three specific services such 455 as machining, cleaning and steam generating can be separated boundaries where energy 456 efficiency is evaluated with its own inputs, outputs and KPI as an example. The EE 457 improvements are independently assessed and implemented. 458

459

Figure A.1 – Boundary setting example: 460 three boundaries for independent solution 461

Another way is to define a wider boundary with one combined service “machining and 462 cleaning” to produce the same output. Machining and cleaning are parts of one group in this 463 view. (Figure A.2). 464

465

Figure A.2 – Boundary setting example: a boundary of a group 466

Once this kind of group boundary is defined, more systematic solutions, which might not be 467 considered with individual services, can be raised and assessed. 468

In the example of machining and cleaning boundary, replacing the boiler with a heat 469 exchanger is one of the solutions for the problem that heat (energy) is lost while heat (steam) 470 is generated (Figure A.3). 471

Depending on the situation, group energy efficiency view can help achieving much more 474 efficiency than that by individual efforts. 475

Annex B 476

(informative) 477

The extended product approach as a collaborative example 478

B.1 Sharing the TC responsibilities 479

This Annex gives an example how in a practical case the contributing TCs may find a common 480 understanding how to collaborate in energy efficiency. 481

B.1.1 Practical case 482

Figure B.1 illustrates how different components may be integrated as a system or equipment 483 in a real production plant. 484

The first step consists of defining the different boxes included in the EE standard to be 485 developed. An example is shown in Figure B.1. It also represents the different levels of 486 responsibilities of the dedicated TC’s. 487

The example is drawn from a production plant consisting of different equipment’s where one 488 which includes a pump system. 489

The dedicated responsibilities will be limited to each product boundary to be handled. 490

This pump system consists of a motor system and a pump unit and both consist of a converter 491 a motor and impeller and housing respectively. The motor system itself contains a converter 492 and a motor and the pump unit contains an impeller and housing 493

494

495

Figure B.1 – Relation between different components at different levels 496

– 20 – IEC GUIDE119 © IEC 2015

Energy efficiency standards would be possible for each and every box as an individual 497 classification standard or individual loss calculations dependent on how and where the 498 dedicated KPIs are defined. 499

As the KPIs may be different, going up the different responsibility levels shown in figure 1, the 500 extended product approach is a concept to sharing the responsibilities of collaborating technical 501 committees, while respecting the KPI of the next upper level. This is done as the relevant output 502 data from one responsibility level boxes are the same as the input data of the next upper level 503 boxes reuniting the first ones. 504

Doing this together collaboratively between the relevant TCs, will give an idea on how the different 505 standards should interact and how the requirements are complementing. 506

B.1.2 Example how different TCs may determine their role in an a common 507 collaboration 508

Each box in Figure B.1 stands for a component or an extended product (e.g. system) and 509 would be represented also by a responsible technical committee. 510

The red arrows show the direction of the evidential evolution from a component to a plant 511 incorporating more elements. 512

Each TC may also have its own driving values (KPIs) but a limited understanding/influence of 513 the driving values from the next upper responsibility levels. 514

In case no collaborating exists, the red arrows may just indicate an arbitrary KPI like an 515 efficiency classification from the lower level component, without reflecting if this KPI would 516 give appropriate system efficiency relevant information for use of the upper level. 517

Nevertheless they could improve both while collaborating in EE-standardization, because the 518 lower level TC in Figure B.1 fulfills the upper level TC specifications, otherwise the system 519 won’t work properly. 520

521

Figure B.2 – Link between every box corresponding TC’s 522

In the illustrated example the technical committee TCa would be the customer of TCb and the 523 two TCs e and f would be the suppliers for TCc (see Figure B.2). 524

IEC GUIDE 119 © IEC 2015 – 21 –

B.1.3 Example how different TCs should share their responsibilities 525

According to the different viewpoints in every responsibility level and sharing specifications 526 with others, it will be clear that some collaboration in the EE-standardization work would be 527 advantageous. See Figure B.3. 528

529

Figure B.3 – TC’s responsibilities with EE Key parameters at the different levels starting 530 from the plant level and going down to individual components 531

If the common understanding has been agreed for the EE-standardization work, the product 532 standard of the lowest level component may give a requirement that will indirectly be 533 contributing to lower the Operating Expenses (OPEX) of the plant. 534

Vice versa, the implementation team would correctly select the products or the system in 535 order to achieve the satisfaction of the plant responsible. 536

In practice, this will work if the TCs are working together at different responsibility levels. 537

B.2 Practical example 538

B.2.1 A motor system and pump system collaboration 539

In this example shows two TCs at different levels and their functional interaction and 540 collaboration for the EE will collaborate in the extended product approach. 541

The collaboration is shown in Figure B.4 where on the left side the two collaborating 542 committees (pump system and motor system committees) are illustrated. The requirements in 543 the middle commonly linked together in a standard. The right side is the outcome as being two 544 semi analytical models (SAM of the pump system and SAM of the motor system) which need 545 to interact in order to realize their optimal contributions. 546

– 22 – IEC GUIDE119 © IEC 2015

547

Figure B.4 – Interaction between the two SAM’s 548

The interaction of the both semi analytical models is called the extended product approach 549 (EPA), because in this terminology the pump unit was originally defined as being the product 550 together with the extension of the pump unit by a motor system (“extended product”). See 551 Figure B.5. 552
