GB/T 42455.2-2024Smart city - Building and residence community - Part 2: Smart community assessment (English PDF)

3 Terms and definitions

3.1 Integrated community service platform: an integrated management platform based on the internet, the internet of things, big data and artificial intelligence that brings together, optimizes and shares the various resources of a community, raises management efficiency and service level, improves safety and convenience, and lifts the quality and value of the community.

3.2 Digital home: a digital household living service system carried by the dwelling that uses the internet of things, cloud computing, big data, mobile communication and artificial intelligence to interconnect the platform and the household products and to meet the occupants' needs for obtaining and using information.

Clause 4 lists three abbreviations: API (application programming interface), CIM (city information model) and ETC (electronic toll collection).

5 Basic provisions

5.1 The applicant shall identify the community operating body and shall have a mechanism for the long-term effective running and continuing upgrade of the integrated community service platform. At the time of application the platform shall already be running effectively and shall hold at least 3 months of operating data. The applicant shall carry out a self-assessment against the indicators of the document and shall submit the self-assessment report and the supporting material.

5.2 The indicator system is made up of four indicator classes, infrastructure, integrated community service platform, community management and community services, each containing control items and score items, and a further set of bonus items applies across the system. Control items are judged as compliant or not compliant; score items and bonus items are judged by a score. Each class of score items carries a total value of 100 points, and the score of each class is multiplied by its weight; the bonus items also carry a total value of 100 points, awarded under Clause 10. Table 1, which has one column per indicator with a total-value row and a weight row, gives 100 points and a weight of 0.30 to infrastructure, 100 points and 0.20 to the integrated community service platform, 100 points and 0.25 to community management, 100 points and 0.25 to community services, and 100 points and 0.20 to the special features and innovation bonus. The total score of Formula (1) is the sum of each indicator score multiplied by its weight.

5.2 (continued) Table 2 sets the grades against the total score: above 90 points, five stars; above 70 and up to 90 points, four stars; above 50 and up to 70 points, three stars; above 30 and up to 50 points, two stars; 30 points or less, one star. All control items have to be compliant in every case: with all control items compliant and a total score of 30 points or less the community is rated one star, and with all control items compliant and a total score above 30 points it is rated between two and five stars according to the score obtained.

5.3 The assessment body reviews the self-assessment report and the supporting material, carries out a site visit and watches a demonstration of the system, fills in the assessment tables of Annexes A, B and C and the score summary table of Annex D, and issues a smart community grading report.
