Building Digital Twin Energy Optimization

@Aaleen110

The main challenge here is starting with partial data and making it work, then scaling up as more sensors come online, so I'll build the digital twin using Dynamo for Revit to connect to the BIM model and pull geometric and system data, then use Python scripts to process the BMS exports and sub-metering data. For the monthly utility bills, I’ll integrate them as a baseline and for validation. I’ll use EnergyPlus for the physics-based engine, as it’s a strong standard for this kind of building energy simulation. When I have the live and historical data, I will calibrate the EnergyPlus model against it, using the sub-metering to check critical zones and the utility bills for overall building consumption. I assume you want the digital twin to be able to forecast performance and savings for potential retrofits, showing payback periods for those improvements. The dynamic dashboards will be built in Power BI to visualise the KPIs and the results of your "what-if" scenarios. My assumption is that the Revit files you provide are up-to-date and accurate representations of the building's current systems. If there are discrepancies, we’ll need to identify and resolve them during the data integration phase. What is the primary source for your sub-metering data exports, and in what format are they typically provided? Preferred Freelancer here, and I have not missed a deadline or gone over an agreed price yet. If you hand over the job, the first day or two will be spent importing the Revit files into Dynamo, setting up the initial data ingestion scripts for the BMS exports, and building the basic Power BI framework to show the current energy consumption based on the utility bills.

As a seasoned Data Analyst and Scientist with over eight years of experience, my specialization lies in extracting actionable insights from complex datasets. I have a strong background in **data storytelling and developing advanced dashboards**, which are essential skills for executing your project successfully. With my proficiency in **Power BI, Looker, SQL, Python, ML, Dashboards, and Advanced Excel**, I can construct a tailored digital twin model for your building that zeroes-in on energy use and HVAC optimization. Having worked extensively on data visualization platforms like Power BI and Tableau, I'm qualified to design the web-based dashboard you require. It will not only present real-time KPIs but also highlight consumption trends and offer optimization recommendations. Additionally, my experience with handling incomplete data in various industries is valuable since it enables me to fill the data gaps efficiently using BMS exports, sub-metering data, monthly utility bills, BIM files (Revit), etc.

Hi, I can build your building energy digital twin focused on HVAC and whole-building consumption, using your Revit/BIM files, BMS exports, sub-meter data, utility bills, simulations, and dashboard reporting. The best solution is to first review your BIM model, available meters, BMS points, utility history, HVAC system type, and missing data gaps. Then I’ll create a calibrated model using EnergyPlus or an equivalent simulation workflow, connect CSV/BACnet-style data inputs, validate predicted vs actual energy use, and build a clear dashboard for KPIs, trends, anomalies, and retrofit “what-if” savings. I’m comfortable with building energy modeling, BIM/Revit data use, HVAC analysis, EnergyPlus-style simulation, data integration, Power BI dashboards, anomaly detection, predictive analytics, energy optimisation, and payback calculation. Deliverables will include: * Calibrated energy digital twin * HVAC and whole-building demand model * CSV/BACnet data integration scripts * Utility and sub-meter data mapping * Energy trend dashboard * Anomaly alerts * What-if retrofit scenarios * Predicted savings and payback estimates * Validation summary * Handover guide and walkthrough I’ll focus on a practical, scalable model that works with your current partial data and can expand as more sensors come online. Best regards Ankit

As a researcher at COMSATS, my proficiency in classical and quantum mechanics, material sciences, theoretical physics, heat and thermodynamics make me uniquely qualified to build your digital twin energy optimization model. Drawing from my vast experience in computational physics, I am well-versed in utilizing physics-based engines such as EnergyPlus to create highly accurate simulations, hence providing you with a fully calibrated digital twin that focuses on HVAC systems and whole-building demand. Additionally, I am adept at scripting and connecting data sources (BACnet/IP and CSV imports) ensuring seamless integration of your existing data. My strength in Mathematical methods of physics and statistics ensure that I can present clear actionable outputs related to your energy consumption such as predicted savings, payback periods, and dynamic dashboards. I am also conversant with tools such as Power BI for creating intuitive dashboards that can be understood by your team without a steep learning curve. Finally, my proficiency in MatLab and Orange Data Mining software significantly enhances my ability to analyze complex data sets efficiently. The projected success of this project is the ability of your Twin to provide accurate predictions as well as clear optimization recommendations; skills I have demonstrated repeatedly on similar projects. I'm confident that with my skill set, we can build a solution that surpasses your expectations.

@codeandcommand

Since you only have partial building data right now, I would start by cleaning what you have, run Python for anomaly detection on HVAC readings, then layer a Power BI dashboard on top so energy waste is visible day to day. I can start today, first pass in 5 days. This estimate is based on the post as written, we will refine it once we cover your full data setup. Want me to send a quick scope doc?

@Zahi9

Starting from partial data (BMS exports, a handful of sub-metered panels, monthly bills) is a normal starting point for this kind of build — I'd begin by importing your Revit BIM geometry, mapping it to an EnergyPlus (or equivalent) model, and calibrating against what real data you do have while flagging exactly where gaps exist so we know what future sensors should target first. I'll build BACnet/IP and CSV connectors for live and historical ingestion, focus the calibration on HVAC and whole-building demand as you specified, and surface predicted savings, payback periods and anomaly alerts through a Power BI (or web) dashboard your facilities team can actually use day to day. I'll validate the model against actual usage over your two-week window before calling it done, and can share an outline of how I've approached similar builds with incomplete initial data. What sensor/BMS protocols are currently exposed, and is Revit the authoritative BIM source or is there a separate as-built model?

@ExactSpec

Your objective: turn partial BMS/CSV meter exports and monthly bills into a calibrated, actionable digital twin that identifies HVAC and whole‑building savings, supports “what‑if” retrofit scenarios, and hands your facilities team a clear dashboard and operating procedure. Recommended approach below is pragmatic: start with data triage, build a minimal physics+data model that validates gaps in a short pilot, then expand connectors, visualisation, and automation. Fixed price and staged delivery keep scope and risk visible.
