d. Proposing the requirements for standards development in this field, particularly related to electrotechnical aspects.
This SRD is for use by urban managers, solution providers, urban operators, citizens, and other relevant stakeholders, to identify the practices of IOC, and what tools they could use to implement this good practice. It also might help IOCs under development to identify the capabilities and standardization needs, and makes the city more desirable and smartness.

IEC SRD 63347-1:2025 This part aims to explain how the work of ‘Management of Public Health Emergencies in Smart Cities’ use case collection and analyses address “Urban Immune System”, provide a brief overview of ‘Public Health Emergencies in Smart Cities’, and identify the key application areas and stakeholders of ‘Public Health Emergencies in Smart Cities’ It will also identify standards requirements relating to overall guidance documents and standards relating to overarching issues.

IEC SRD 63326:2025 This framework provides a brief of City Needs and Smart City Framework, explains the importance of it in supporting Smart Cities, specifies the vision, mission, and the role of the proposed New Working Group of City Needs Framework, and explains the approach which would be adopted, and the operating principles. This context has occurred after the intelligent movement, while the time right to conclude the framework that supporting policies and standardization have a positive effect on the urban growth. This document discussed the special structure of cities and reviewed the performance, creating the framework with methodology about smart cities requirements. The framework methodology help stakeholders (governments, private companies, universities and research institutions, and civil society and so on) across clearly when looking at the micro-foundations view. Helping governments and developers, understanding the rules well, finding the high-efficient way to achieve the goal, helping citizens could living better, the problems while could be solved, helping researchers could know the smart projects exploration.

IEC STRD 63320-2:2025 The purpose of this NP is to collect the use case of smart urban planning for smart cities, analyze the collected use cases of smart urban planning (categories analysis, functional analysis, stakeholder needs analysis, etc.), bring out the requirements of relevant standards of smart city in the future, and put forward relevant suggestions.

IEC SRD 63302-1:2025 provides use case collection and analysis, identifies the market relationships of relevant stakeholders, scopes out capabilities and a reference model of intelligent operations centre (IOC) for smart cities, and proposes the requirements for standards development in this field.
Digital solutions are accelerating the integration of real world applications in urban areas, including city governance, healthcare, environment, traffic, education, security and so on. However, many smart solutions are still implemented within single-domains. Isolated city services, data flows and data need integration. To be effective, the coordination of data and service requires an overarching framework coupled with an intelligent operations centre. The first step to identify solution options is by collecting and analysing relevant use cases.
IOC is tailored to provide urban managers, enterprises and citizens with access to operational and organized solutions. Based on city-level database and new technologies, such as big data, AI, cloud computing, blockchain etc., IOC processes city information and provides innovative services for urban managers, operators and other stakeholders. Compared with single-domain systems, IOC can better support monitoring and visualizing, decision making and cross-domain cooperation. IOC will play an important role in integrating city services such as police, health services traffic management and rescue services, including but not limited to the following methods.
a) The centralized operations dashboard and mobile application will allow real-time monitoring and information processing to improve response to emergencies.
b) The centralized and intelligent platform will enable noticeable improvements in the management of public safety, like crime prevention, emergency response, threat prevention and response, and traffic management.
c) The IOC's technologically advanced analysis, integrated communications, GPS and video surveillance capabilities will help residents and domain (energy, water, horticulture, waste and security) supervisors to collaborate in a smarter way.
d) The integrated data visualization, near real-time collaboration and deep analytics it provides will help agencies prepare for problems, coordinate and manage response efforts and enhance the efficiency of services,
e) IOC will enable residents to report issues such as broken street lights, electricity failure, water wastage, etc. and check resolution status using their mobile devices.
Currently, IOC solutions are being implemented in different cities around the world, and the stakeholders of these smart cities face similar challenges, including cross-domain cooperation, monitoring and visualizing, intelligent analysis, user-oriented experience, etc. The provision of standardization should be considered as one of key factors to support IOC development, including the development of the conceptual model, data exchange, IT infrastructures, services, and so on. This document focuses on collecting and analysing use cases from diversified areas, with the goal of developing consensus-based descriptions of IOC features and capabilities across all stakeholders, and uses this to scope out the standardization requirements related to the field of IOC.
This document is for use by authorities, solution providers, utilities, citizens, and other relevant stakeholders, to identify good practices regarding IOC, and how they can implement them.

IEC 60050-831:2025 gives the terms and definitions used in smart cities and smart city systems, as well as general terms pertaining to specific applications and associated technologies. This terminology is consistent with the terminology developed in the other specialized parts of the IEV. It has the status of a horizontal standard in accordance with IEC Guide 108.

IEC SRD 63301-1:2024 provides an overview of water systems in smart cities, establishes a general approach for use case collection and analysis, and identifies major stakeholders and application areas for high-level analysis of water systems.
The construction of a smart city can create benefits for a society and its stakeholders. Water is a critical resource to support urban development and its sustainable use is recognized as a UN Sustainable Development Goal. Water infrastructure development, water management efficiency, water supply resilience, and the safe operation and use of water are important focal areas for smart cities.
This document focuses on water systems management, specifically water security whether directly from a natural source or via man-made infrastructure. Information and communications technologies (ICT) and electro-technologies can provide greater visibility and control, however their application does depend on the characteristics of individual water markets. Technology is not a panacea for resolving all issues and problems.
A gap exists in effective coordination and clear orientation and how industry and stakeholders are engaged within it.
Major stakeholders of water management and use include citizens, the water authority (government), and organizations (associations, business groups, utility companies). Each stakeholder has different and competing interests, market relationships and touch points to water system infrastructure, processes, operations, management and use.
Modelling these complex interactions into a systems architecture is a valuable exercise in understanding the issues, gaps and opportunities for sustainable water management.
This document focuses on use case collection and analysis to elicit requirements to support technical committees in preparing sustainable water management standards for cities and communities.

IEC SRD 63520:2024, which is a Systems Reference Deliverable (SRD), provides the concept system of energy challenges in smart cities, using the methodology framework and development processes in IEC SRD 63235.
This document is applicable to development and improvement of the terms and concepts relevant to energy challenges in smart cities.
As global climate change and energy scarcity become increasingly prominent, it is important that cities and stakeholders proactively address energy challenges to achieve the Sustainable Development Goals. According to the IEC White Paper Coping with the Energy Challenge – The IEC's role from 2010 to 2030, cities are facing the following major energy challenges: stabilizing climate impact from fossil fuel use; meeting the energy demands of a growing urban population; bringing electricity to citizens without access; ensuring stable and secure energy access for all cities.
Cities are very complex "system of systems", including power grid (energy), industry, buildings, transport, water, waste and other domains, each of which plays an important role. Various domains play an important role in coping with urban energy challenges. On the one hand, not only is it important for the power grid domain to be transformed, but also for industry, buildings, transport and other domains to take proactive measures. Therefore, it is essential for stakeholders in different domains to reach a consensus on energy challenges (including but not limited to the intension, solutions, visions, etc.), which is conducive to improving the pertinency, systematization and effectiveness of the city's response to energy challenges. On the other hand, from the perspective of urban governance, it is not the most effective for each domain to cope with energy challenges independently, and the comprehensive governance capacity of cities to cope with energy challenges can be significantly improved through cross-domain collaboration, interoperability and integration.
Semantic interoperability is proposed by the IEC White Paper Semantic Interoperability: challenges in the digital transformation age. Research on semantic interoperability is being carried out or planned in the future in the domains of city, power grid (energy), industry, buildings, transport, etc. For example, in the domain of city, IEC SRD 63476-1 provides a gap analysis of smart city ontology; in the domain of power grid (energy), IEC SRD 63417:–[1] provides guidance and planning for the development of smart energy ontologies. Domain-based ontologies have been developed for semantic interoperability in a specific domain, but there is a lack of cross-domain semantic interoperability research. IEC SRD 63417:– includes the following recommendation: "Start a joint work with IEC SyC Smart Cities and IEC SyC Smart Energy on cross domain ontologies".
From the perspective of urban governance, focusing on cross-domain semantic interoperability and at the same time considering the diversity of technology application in rural and remote areas, this document builds a concept system for energy challenges in smart cities, covering core concepts such as intension, stakeholders, solutions and visions of energy challenges. As semantic interoperability research is being carried out or planned in power grid (energy), industry, buildings, transport and other domains, SyC Smart Cities will not be involved in semantic interoperability within these domains. The concept system of this document contains the core concepts of the city domain and the core concepts of cross-domain. The core concepts relevant to energy challenges in other domains, such as power grid (energy), industry, buildings, transport, etc., are developed for semantic interoperability within each domain and fall outside the scope of this document. The purpose of this document includes, but is not limited to:
fostering the coordination of perspectives on energy challenges among stakeholders in different domains of city,

IEC SRD 63476-1:2024 provides a gap analysis on ontology relevant standards for smart city systems to be used as a base document for mapping, developing and maintaining a set of ontology standards for smart city systems.
Ontology is becoming a key subject in the world of big data, AI, IoT, and smart city system standards. The following benefits of ontology are recognized as important with respect to interoperability, connectivity, traceability of digital content, particularly machine readability, executability and interpretability of digital content for decision making and actions.
- Increase interoperability across domains.
- Enable machine-readable code for computational reasoning and decision making.
- Create semantic linkages between data, information and knowledge systems.
- Build accessible APIs and semantic linkages between web-based data objects.
- Link data domains with shared concepts or canonical data models.
- Connect shared data concepts and definitions between domains.
However, ontology has a variety of definitions in different international standards. How to understand different meanings of ontology and select the right definition for the right stakeholders’ concerns for the right purposes is a big challenge for effective integration of business, data, information, knowledge and decision making, across disciplines, domains, systems, platforms and applications in smart cites. Moreover, how to deal with the grand challenges of interoperability of many and various ontologies to satisfy the demands from artificial intelligence and big data analytics are gaps to be filled in the area of smart city systems. How to develop digital content that is machine readable, executable and interpretable, working in the system without human effort for a smart city system are emerging needs to be studied. There are significant demands for better communication, coordination, cooperation, collaboration and connectivity of existing ontology standards to smart cities practical sectors. This document aims:
• to identify existing ontology standards from different Standards Development Organizations (SDOs) and to provide best practice examples and considerations of ontology standards development and maintenance for smart city systems;
• to identify gaps in existing ontology standards for smart city systems and the opportunities and challenges in ontology standards development taking into account multi-dimensional and muti-domain stakeholders’ concerns city wide, and to provide recommendations for ontology standards development and maintenance to enable integration, interoperability, efficiency and effectiveness of smart city systems.

IEC SRD 63273-2:2024 series aims to scope out the requirements of city information modelling standards by collecting and analysing its use cases. Specifically, the IEC SRD 63273 series achieves the objectives of identifying the key application areas and stakeholders, developing user stories and clarifying the relationship among these stakeholders, collecting and analysing use cases of city information modelling, scoping out the requirements for city information modelling standards and providing recommendations to IEC regarding urban planning and management.
The IEC SRD 63273 part 2: 2024 develops the list of user stories and the database of use cases, conducts integrative analyses of the use cases, scopes out the requirements of city information modelling standards and provides recommendations for IEC and other standards development organizations (SDOs) regarding urban planning and management using city information modelling.

IEC SRD 63233-4:2024 This document is part 4 of the IEC SRD 63233 series and proposes a guidance on identifying and mapping standards for public health emergencies following the methodology of IEC SRD 63233-1:2022. It guides identifying and categorizing relevant standards for epidemic prevention and control, and links to a database with cataloged standards for easy use by cities.

IEC SRD 63320-1:2023 In recent years, research on the relationship between information and communication technology (ICT) and cities, focused on imagining the future of urban planning, has been one of the most interesting topics in the industry. Smart urban planning (SUP) for smart cities is a relatively new concept and has not received much attention around the world. The “smartness” of urban planning describes the intensive use of digital technologies to optimize the urban planning process. The concept of "smart city" has been implemented and developed all over the world. In order to construct a smart city successfully, knowing how to implement SUP for smart cities is essential, because it is the foundation of smart urban construction. However, at present, reaching a consensus on the overall architecture of standards of SUP for smart cities is still challenging.
This part of IEC SRD 63320 explains the definition, development goals and theoretical models of smart urban planning use case collection and analyses. This document identifies the key application areas of smart urban planning and determines the stakeholders and the relationships among them in the guidance of use case template.

IEC SRD 63273-1:2023 series aims to scope out the requirements of city information modelling standards by collecting and analysing its use cases. Specifically, the IEC SRD 63273 series achieves the objectives of identifying the key application areas and stakeholders, developing user stories and clarifying the relationship among these stakeholders, collecting and analysing use cases of city information modelling, scoping out the requirements for city information modelling standards and providing recommendations to IEC regarding urban planning and management.
The IEC SRD 63273 part 1 explains how the work of city information modelling use case collection and analysis address sustainable development goals, provides a brief overview of city information modelling, and identifies the key application areas and stakeholders of city information modelling, identifies the key application areas of city information modelling, and determines the stakeholders and the relationships among them in these application areas.

IEC SRD 63233-2:2023 At present, several standards organizations around the world are developing standards for smart cities, but they focus on different aspects of cities. Because a smart city needs a long-term investment, it should provide stakeholders with many standard views with different perspectives as the basis for future investments.
This document is Part 2 of the IEC SRD 63233 series on smart city standards inventory and mapping. Part 1 provides the methodology for inventory and mapping of standards. Part 4 providing guidance on standards for public health emergencies, and Part 3 designed as a standards map are under development.
This document provides a catalogue of the identified standards related to the smart city system according to the criteria specified in IEC SRD 63233-1. This catalogue, as a database or inventory, can provide users with a function to search the smart city-related standard information with the hyperlinks to the searched standards. The inventory of Smart City standards includes not only the existing standards but also those under development officially registered in standards development organizations (SDOs). The inventory is comprehensive, and it provides an overview of each standard catalogued. The users (e.g. designers and implementers of smart cities) can use this inventory to select an appropriate set of standards for their design and implementations. The standards inventory is available online. It will be maintained and updated regularly.

IEC SRD 63152-2:2022 provides design guidelines for implementation of city service continuity (CSC) specified in IEC 63152 and includes city service cases for various target organizations (municipality, town developer, building administrator, etc.). The city service cases included are not only for emergency use but also for normal time use.

The Smart Cities Reference Architecture Methodology (SCRAM) proposes a common methodology for developing the Smart Cities Reference Architecture (SCRA), which is a tailorable template for architectures of, practically, any city system. SCRAM reviews and defines the desired characteristics of Smart Cities, diverse SCRA viewpoints and corresponding SCRA model types in order to promote consistency and uniformity across architectures for various smart cities.

IEC SRD 63233-1:2022 The smart city standards inventory and mapping project was initiated to provide a systematic approach to retrieve and map the standards of smart cities on smart city reference architectures, models or frameworks and provide fundamental support for the collaborative work of standard-setters and users. Standards maps are the practical base for helping SDOs and users to identify directly and instantly the standards that are needed for any aspects of smart cities (citizen services, city infrastructure, governance, etc.). Standards maps also help in identifying the standardization gap in the ecosystem.

IEC SRD 63235:2021 provides a holistic system of systems approach to provide views, methodology framework, principles, processes, rules, and evaluation criteria for smart city system concepts building. While it does not specify the definitions of a smart city system, it provides a methodology based on system approaches for coordination, cooperation and connectivity of the terminology sources including IEC, ISO and ITU. The methodology fosters a multi-dimensional system of systems view on smart city systems across dimensions, domains and layers along the lifecycle of a smart city system, scenarios and use cases, supporting the sustainable development of smart city system arrangements, activities and artefacts, convergence of people, process and productivity globally.

IEC 63152:2020 establishes concepts and gives guidelines to help sustain a variety of city services on the occasion of a disaster from the perspective of providing electricity. It outlines the basic concepts on how multiple city services can cooperate and continue by electricity continuity plan(s) and electricity continuity system(s). It also specifies methods and means to establish these.
The users of this document are assumed to be city developers, city operators, equipment manufacturers, essential service providers and disaster management personnel.
Cities are facing many kinds of potential threats which affect the continuity of city services. There exists, therefore, a great need to establish safe and secure societies in which negative impacts on city services to the citizens are minimized and city services are continuously available to them during a period of emergency. There is no doubt that, in modern cities, electricity plays a critical role in maintaining city services.
