Business sectors

Cohesion skills with each business sector


The main challenge that the HVAC and building mechanics industries face today is how businesses can remain profitable despite the perceived high costs that HVAC/CVAC design-builds, maintenance and optimization can incur. BAULNE created an ebook (French only) that presents two case studies. These case studies provide a compelling overview of two clients, their challenges and business goals, and the results they achieved by implementing SAFRAN and Société de gestion COGIR solutions. They are great reads if you are looking to ensure optimal ROI with your next HVAC/CVAC project.
