IBMS and BIM synergy


BIM and BMS integration creates a powerful synergy that enhances building intelligence and operational efficiency. BIM provides a detailed and accurate representation of the building’s physical and functional characteristics, while BMS offers real-time monitoring and control capabilities. Together, they enable a more holistic approach to building management.

HVAC systems are often the largest energy consumers in a building. A performance study can reveal their operational efficiency. According to EPA’s Energy Star, 30 percent of energy gets wasted. By learning how to use energy more efficiently, businesses could reduce operating expenses and lower emissions. In building management, integrating advanced technologies has become imperative for achieving efficiency, sustainability, and optimal performance.

Building Information Modelling (BIM) and Building Management Systems (BMS) technologies assist building owners and managers in building planning, design, construction, and operational phases, leading to advantages. Initiating a building systems performance study is the first step to unlocking these potential benefits. Bill Ganz, CEO of Sterile Safe Solutions, says managing building systems transcends lowering expenses. It is about taking responsibility for our carbon footprint. Buildings are major energy consumers and offer a significant opportunity for achieving savings and efficiency improvements.

Exploring planning and design for HVAC

Building Information Modelling,  a digital representation of a facility’s physical and functional characteristics allows for accurate visualisation of the project before construction begins. It involves creating a 3D model embedded with essential information that guides the entire lifecycle of a building. Nikhil Murkar, BIM Architect, Turner International India, elaborates on a 3D model with all building information, streamlines documentation and speeds up production. By embedding details into the 3D model, BIM facilitates collaboration, reduces errors, and improves efficiency. BIM is a central data repository from the initial design phase through construction and into facility management, ensuring communication and coordination among stakeholders.

HVAC systems’ modelling in BIM impacts building design and operation. HVAC models enhance discussions and decision-making by offering a detailed and precise system representation. This improves coordination among various trades, minimises potential errors, and integrates the HVAC system with other building components. BIM-based HVAC modelling boosts efficiency and communication and ensures timely project completion. Whether it be opportunities for energy conservation or maintenance requirements, clients must remain informed every step of the way. 

Mahesh Reddy, Head of Customer Delight at 75Femphasises, the strategy involves a robust notification management system that ensures clear communication and real-time updates on building performance. Clients are informed throughout about opportunities for saving energy or maintenance needs. According to Hardik Virkar, Associate and BIM Digital Lead at AECOM, each BIM object contains information about the materials and performance specs, which makes planning and execution a breeze. This wealth of data helps in planning, simulation, and execution, boosting efficiency and decision-making.

Nikhil suggests maintenance teams can access critical details, reduce downtime, and improve response times by having all necessary information within the BIM model. The documentation assures that building components are maintained correctly, extending their lifespan and granting optimal performance.

A Building Management System is a computer-based control system installed in buildings to monitor and manage mechanical, electrical, and plumbing (MEP) systems. Moreover, BMS is crucial for maintaining optimal indoor conditions, ensuring safety, and improving energy efficiency.

Integrated BMS in healthcare facilities

In any health care building, there are several Mechanical Equipment such as Chillers, AHUs, Pumps, Valve, Electrical equipment such as switch gears, Generators, panels, Transformers, PHE equipment such as Pumps, STPs, Boilers,  Treatment plants can be seen in any building along with measuring devices such as Btu meters, DB meters and Energy meters. When the equipment is connected with one central point for a common goal, it is known as the Integrated Building Management system.

Healthcare facilities, with their complex requirements for precise climate control, hygiene, and security, benefit from the integration of BIM and BMS. Hardik explains in a hospital where the temperature is just right, points out that BMS is at work.  In healthcare projects, BMS is crucial in maintaining strict temperature and humidity levels in operating rooms. A case study of a modern hospital demonstrates the impact of these technologies. BIM was used during the design phase to create a detailed 3D model encompassing all critical information about the building’s systems. Integrated with the BMS, this model enables real-time monitoring and control of HVAC, lighting, security, and other systems.

The BMS ensured that operating rooms maintained strict temperature and humidity levels critical for patient safety. It also optimised lighting and HVAC systems based on occupancy, reducing energy consumption. The BIM model provided easy access to detailed information, enabling efficient and timely repairs. Integrating BIM and BMS resulted in significant energy savings, improved indoor air quality, enhanced security, and reduced operational costs. The hospital operated more efficiently, providing a safe and comfortable environment.

The operation and well-functioning of any healthcare unit are much more important than setting up the units. Once a hospital starts functioning, no compromise can be made with its services as then the lives of human beings are at risk. Firoj Jena, Chief Executive Officer of Clancy Global Consulting Engineers, asserts that an integrated building management system (IBMS) must be connected to all mechanical, electrical, plumbing, fire protection, and security systems for their smooth running.

The way forward

Businesses can reduce operating expense costs by implementing the recommended changes from a building performance study. BIM supports the entire lifecycle of a building, from design and construction to operation and maintenance. It acts as a digital twin, providing valuable insights for facility management. BIM ensures that the building operates efficiently throughout its lifespan. BMS integrates security systems, including surveillance cameras, access control, and alarm systems, ensuring comprehensive building security. It provides real-time monitoring and alerts, enhancing safety for occupants.

The integration of Building Information Modelling and Building Management Systems technologies complements each other in building management. It creates an approach to design, construction, and operation. Building owners and managers can achieve higher efficiency, sustainability, and operational excellence by leveraging the synergy between BIM and BMS. As the construction and HVAC industries continue to evolve, adopting BIM and BMS will become increasingly crucial for creating intelligent, efficient, and sustainable buildings.

The crux of the matter is identifying inefficiencies, which helps building owners and managers make informed, impactful decisions. A thorough building systems performance study is a wise move toward a sustainable and cost-effective future by reducing costs and conserving valuable resources.
