duction of the Digital Twin, the industry’s bar has been raised, along with the owners’ expectations. Real estate currently plays a vital role in buildings like shopping centers, residential and commercial structures. Through the space, monitoring, and leasing-related data analysis tools, the Real Estate Management Module facilitates the sales and lease of the project space and provides comprehensive leasing management by integrating it with the ERP system. It offers crucial data, such as real- time rental income, growth rate and fluctuation, space rental status, rental risk analysis, and sales status. The space analysis tool provides screening and analysis of sales and leasing management under different conditions, such as sales status, lease status, area, price, floor, and orientation. Through various visual - ization tools, the manager can view and digest the analysis results and project data in the most intuitive form to spot problems and room for improvement in a timely manner. The space monitoring tool can help managers quickly locate the tenant with overdue rent and its corresponding space and view related space information, displaying prompts in different colors according to the se - verity. Using a more extended period time frame, managers can analyze the number of historical alarms and display the results of overdue occur - rences within the selected period to quickly and accurately locate high- risk tenants and spaces needing more accurate management methods. The leasing-related data analysis tool helps quickly correlate rental key parameters, statistics, and analysis of critical income indicators in the selected period, such as the total income amount, unit income amount, space rental status, etc. It can enable analyzing and mining in differ - ent dimensions, combining management methods, avoiding risks, and increasing the property’s total revenue. Sustainability Module The Sustainability Management Module focuses on addressing the synergetic management of the facility’s equipment and space, along with occupants’ wellbeing. While each facility might have its own de - fined sustainability goals and indicators, these objectives can typically be grouped under three areas: Building Efficiency (energy and water consumption), Building Comfort (occupancy and productivity), and Building Health (environmental wellbeing). These multiple competing factors affecting different aspects of sustain - ability performance are the intricate part of sustainability management. The management of equipment alone is no longer sufficient; it is neces - sary to consider how the equipment serves the space’s functionality. Comfort and health thresholds become part of operational criteria to determine the management strategies. Therefore, the core objective of this module is to provide an integrated platform to support facility managers with related data, translated performance indicator values, and trade-off analyses for informed decision-making based on their predefined performance priority logic. Its foundation includes an exhaustive list of assets and building com - ponents along with their sustainability-related attributes and real-time usage data, as well as their location properties to determine their cor - relation performance thresholds. Building on top of these data founda -
tions, the platform integrating IoT, building automation system, and CMMS can provide insightful information to support sustainability management or automate the O&M based on predefined logic. For example, when an occupancy sensor detects an office space is not in use, the platform can automatically shut off the lights to reduce lighting usage, turn down the outdoor air rate to minimize HVAC operation, and close shades to reduce the solar heat gain. The plat - form can also provide visualization for different sustainability per - formance indicators to facilitate HCI and gather that data for future operational reference. Summary This installment of Practical BIM Implementation for Facility Man - agement has broken down the five essential application modules in an ideal Digital Twin platform. Each module represents an aspect of a holistic facility management approach that is highly interrelated to the others. Modular data analytics and reporting give us the freedom to perform quantification analysis on each focus area in the facility in terms of space, sustainability, safety, operation, and maintenance. This practice informs the end-user with straightforward information about the facility’s performance by building, floor, or any predefined space via the scoring system. The next segment will disassemble each facil - ity’s health category into sub credits, present a high-level picture of the scoring system, and discuss its collaboration with the AM/FM LOD.
