Building resilient, sustainable healthcare with digital twins and innovation

Energy Transition Talks

In the latest episode of our Energy Transition Talks series, CGI Global Industry Lead for Health and Life Sciences Ben Goldberg joins Peter Warren to discuss the interdependence between healthcare and energy systems, emphasizing the need for a balanced approach to ensure a healthy society. Specifically, they examine the interplay between ecosystems and supply chains, the emergence of smart, “green hospitals,” and how data innovation and digital twins are driving sustainable, resilient healthcare.

Digital twins and “triplets” in healthcare

While hospitals play a vital role in healthcare, they often contribute significantly to emissions due to aging infrastructure and inefficient buildings. For example, Ben points out that many hospitals have been around for decades, and while some modernization efforts have been made, they are still not energy friendly. This, he says, is an opportunity for new technologies to enter the mix.

Notably, digital twins—which create digital representation of physical assets—have gained traction in healthcare. Moving beyond just monitoring energy consumption, digital twins offer compelling use cases, such as providing visibility into the patient journey and help address outcomes. As Ben highlights, the ability to mirror the physical world digitally through digital twins has numerous facets and opportunities within the healthcare sector.

Sharing a term coined by Diane Gutiw, a leader in AI and digital twins at CGI, Peter raises the use cases for “digital triplets,” referring to using three interconnected digital twins:

1. A twin modeling the patient’s health and wellbeing
2. A twin modeling the operations of the healthcare facility itself (energy use, HVAC systems, etc.)
3. A third twin analyzing the causes and effects between the first two twins.

This model allows for optimizing not just patient care, but the facility's energy efficiency and sustainability as well. For example, Ben and Peter discuss the fact that "green hospitals" are being built globally to produce their own electricity and hydrogen fuel, while using digital twins to intelligently control heating, cooling, lighting, and more based on patient occupancy levels.
