A collaborative project leveraging quantum computing has taken an important step in the realm of sustainable building design. This initiative, a quantum proof of concept (qPoC) spearheaded by VINCI Energies | DIANE, uptownBasel | QuantumBasel, and D-Wave (NYSE: QBTS), focused on optimizing the design of heating, ventilation, and air conditioning (HVAC) systems for complex buildings.

The project's first phase successfully transformed the complex HVAC network generation problem into a constrained quadratic model (CQM), potentially efficiently solvable by D-Wave's quantum-classical hybrid solvers. This marked a clear step away from traditional computational methods to a more innovative, quantum-classical hybrid approach.

The implementation and experimentation phase saw the CQM translated into Python code and processed by D-Wave’s hybrid solvers. These solvers, utilizing using both classical and quantum devices, identified superior HVAC network designs, outperforming the existing data-driven method in significant ways. Notably, the new approach yielded solutions more quickly with shorter duct lengths and fewer construction elements, such as elbows. In addition, subject matter experts from VINCI Energies visually and manually inspected these solutions, confirming their superiority in terms of quality. Importantly, these results were based on one representative building plan and diverse HVAC systems, setting the stage for broader application in the industry.

A crucial factor in the project's success was the interdisciplinary team. Team members from Europe (Switzerland, France, Germany) and North America (Canada, USA) brought specialized knowledge and experience, resulting in rapid progress and efficient problem-solving. This global team operated seamlessly through collaboration tools, demonstrating the power of virtual teamwork in achieving cutting-edge innovation.

As the project moves forward, the focus will shift to translating these technical improvements into tangible business impact, such as reduced computation time and less manual engineering effort.

This quantum computing project stands as a testament to the power of collaborative innovation in driving sustainable and efficient solutions in building design. It marks another important step towards a more sustainable future, in which human expertise and technology join forces to create environmentally friendly and cost-effective building solutions.

About uptownBasel and QuantumBasel

uptownBasel serves as a global hub for Industry 4.0, seamlessly connected to the world while firmly rooted in Basel, Europe. Situated on the historic Schorenareal site in Arlesheim near Basel, an expansive research and production facility covering approximately 70,000 square meters is being constructed. With the opening of Building 1 and its use by the two European technology groups Bouygues and Vinci (Axians and Actemium), the campus has already created 400 new jobs since 2021. In total, the center will house about 100 companies, generating up to 2500 jobs. The investment volume amounts to over 500 million Swiss francs. uptownBasel is made possible by the private ownership of the Monique and Thomas Stæhelin family and implemented by Fankhauser Arealentwicklungen.

QuantumBasel, a wholly owned subsidiary of the uptownBasel Group, runs “QuantumBasel,” its Center of Competence for Quantum and Artificial Intelligence and the first commercial quantum hub in Switzerland. Seamless access to quantum and high-performance computing is made available to tenants and the eco-system of uptownBasel, including enterprises, research institutes, startups, and universities. Collaborating with esteemed technology partners like IBM, D-Wave, and IonQ, QuantumBasel is also expanding its global network to encompass research institutes and universities. www.quantumbasel.com
