The Building Information Modeling (BIM) can be a revolutionary tool for modern agriculture, combining the potential of digital technology with the needs of a sector increasingly focused on efficiency and sustainability.

Thanks to its ability to create detailed digital representations of the physical and functional characteristics of buildings and land, BIM integrated with GIS and Digital Twin can transform the way agricultural companies design, manage, and optimize their activities. The integration of BIM, GIS, and Digital Twin in the management of agricultural and livestock activities allows for the integration of data analysis of Digital Twins, the spatial analysis of the entire corporate territory typical of GIS, with the detailed analysis that BIM allows on each individual structure, such as farms, stables, warehouses, or processing and production sites, or even sales locations.

Main applications of BIM in agriculture

The integration of BIM (Building Information Modeling), GIS (Geographic Information System), and Digital Twin is transforming the agricultural sector, offering new opportunities for the management and optimization of activities. Below are examples of some main applications of BIM in the sector.

Design and management of agricultural structures with BIM

Building Information Modeling (BIM) can certainly help create more efficient, sustainable, and optimized agricultural buildings thanks to its ability to integrate complex data and provide detailed 3D digital representations. Here is an in-depth look at the advantages, tools, and applications of this technology in the agricultural sector.

1. Tailored planning and design

BIM allows for the design of agricultural buildings such as greenhouses, stables, warehouses, and processing plants by integrating key variables, including:

• local climatic conditions: BIM models can take weather data into account to design structures capable of optimizing temperature, ventilation, and natural lighting;
• specific functionalities: each structure can be customized for the needs of specific crops or activities, such as greenhouses or stables for intensive farming​​.

Thanks to BIM’s three-dimensional simulation, it is possible to virtually test projects before construction, verifying their ability to meet agricultural requirements​.

2. Resource management and optimization

After construction, BIM transforms into a dynamic tool for the operational management of agricultural structures:

• real-time monitoring: through integrated IoT sensors, agricultural structures can be monitored to check critical parameters such as temperature, humidity, energy consumption, and equipment status​​;
• predictive maintenance: BIM can identify impending failures in structures or machinery, allowing for timely interventions and reducing repair costs​;
• space optimization: for warehouses or greenhouses, BIM allows for planning the layout of spaces to maximize storage capacity or crop yield.

3. Greenhouse design and advanced technologies

A specific application of BIM is the design of high-tech greenhouses, where every element is optimized to maximize productivity:

• environmental simulations: BIM allows for simulating the impact of various environmental factors, such as sunlight or airflow, to design greenhouses that ensure ideal growth conditions​​;
• automated systems: greenhouses can be integrated with automation systems for irrigation, heating, and ventilation, all controllable through a BIM interface​.

4. Smart agricultural warehouses

Warehouses designed with BIM are optimized to ensure:

• efficient preservation: BIM simulations can model heat distribution and humidity to prevent deterioration;
• improved logistics: optimal layouts that facilitate loading, unloading, and inventory monitoring​.

5. Stall design with BIM

BIM allows for the design of stables that best meet the specific needs of animals and operators:

• space optimization: thanks to three-dimensional models, it is possible to plan layouts that ensure maximum efficiency in the arrangement of areas for feeding, resting, and milking;

• climatic simulations: BIM models integrated with local climatic data allow for designing ventilation, insulation, and thermal control systems that improve animal comfort and reduce energy consumption​​.

6. Energy assessments and sustainability

Another crucial aspect is the ability to analyze and reduce the energy consumption of structures:

• low environmental impact design: BIM allows for choosing sustainable materials and integrating technologies such as solar panels and rainwater harvesting systems​​;
• waste reduction: detailed planning of structures reduces design errors and excess materials during construction.

Applications of BIM in agriculture

Digital Twin for Real-Time Monitoring in Agriculture

The concept of Digital Twin is one of the most promising applications of Building Information Modeling (BIM) in agriculture. Thanks to this technology, it is possible to create a digital replica of an agricultural structure or an entire farm, allowing for real-time monitoring of operations, improving resource management, and optimizing productivity. This solution integrates IoT sensors, big data, and BIM models, providing farmers with a comprehensive and up-to-date view of their assets.

By integrating BIM, GIS, and IoT, we can have real-time data simulated in a 3D virtual environment for both structures and infrastructure as well as the land. Alerts and data will appear in a single virtual environment accompanied by information analysis dashboards thanks to the application of technologies such as Business Intelligence (BI) and Artificial Intelligence (AI).

The concept of synchronized virtual representation in real-time positions the Digital Twin as a turning point in modern agriculture. By integrating data, “what-if” simulations, and advanced modeling, Digital Twins can transform agricultural operations, supporting companies in making informed decisions and increasing large-scale automation.

Since its introduction, the Digital Twin has expanded its requirements, capabilities, and areas of application. Originally designed for industrial and manufacturing purposes, it has evolved to adapt to new contexts, such as agriculture, where its potential is increasingly evident. However, the expansion of the definition has raised some critical issues, including:

• terminological confusion: the incorrect labeling of general computer models as Digital Twin;
• model fidelity: uncertainty about the level of accuracy required to define a model as a Digital Twin.

The Classification of Digital Twin According to Kritzinger

To clarify the ambiguity and standardize the definition, Kritzinger proposed a classification system based on the level of data integration between the physical entity and its digital representation. This approach distinguishes three main categories:

1. Digital Model:

• description: a digital representation without automatic data exchange between the model and the physical entity;
• characteristics: this is the lowest level of integration, where the model serves as a static prototype, useful for preliminary analyses;
• example in agriculture: a static model of a field or greenhouse used to simulate crop planning.

2. Digital Shadow:

• description: a digital representation with automated information flow in one direction, from the physical entity to the virtual model;
• characteristics: changes in the state of the real entity are reflected in the virtual representation, but not vice versa;
• example in agriculture: IoT sensors in a greenhouse sending data about the microclimate to the virtual model to monitor environmental conditions.

3. Digital Twin:

• description: a fully integrated digital representation with bidirectional information flow. Not only does the twin reflect the state of the physical entity, but it can also influence it;
• characteristics: this level allows for real-time simulations and automated interventions, dynamically adapting to operational needs;
• example in agriculture: an automated irrigation system that adjusts the water flow based on real-time data from a synchronized virtual model.
