Similarly, for the use case of air quality monitoring, CO concentration is the KPI. A CO sensor reads 10 ppm and feeds the information to the performance dashboard. The SDDMS can then provide a performance threshold considering the space properties and correlated green stan - dards. Since it is an office space, a healthy indoor CO concentration should be maintained within 9 ppm per WELL Building Standard. Therefore, the value can be used to set the alarm to inform the air qual- ity condition and trigger corresponding actions accordingly. Conclusion To continue the previously-introduced digital twin framework, modular analytics, and scoring system, we present an SDDMS that can poten - tially bridge the gaps of lack of domain knowledge, data connection, information exchange requirements, and data mapping and synergy to facilitate sustainability in FM. While several essential information and data specifications mentioned in this article are not new, these data requirements are currently utilized and applied sporadically in differ- ent green building standards, building data exchange standards, and BIM implementation framework. While the development and adoption of ISO 19650 series presents potential benefits to the project lifecycle’s data management, an SDDMS would still be the essential foundation for supporting the data flow and activities throughout the building lifecycle, especially for sustainable development. The final installment of this series will summarize and discuss the promising integration of BIM, AM/FM LOD, modulization, health assessment, data analytics, reporting, and sustainability into one platform with generalized case studies to disclose its full potential and functionality to benefit end- users from all levels.
