ROI Calculation Logic

For companies managing 20 HVAC design projects annually, traditional outsourcing or CFD software costs ~$20K per project, totaling ~$400K/year (AI est.). This technology enables rapid in-house prediction, reducing costs to ~$3.5K per project, for direct savings of ~$350K/year (AI est.). Additionally, a 10% reduction in HVAC power consumption through airflow optimization could yield ~$200K/year in energy savings (AI est.), totaling ~$500K/year in economic benefits (AI est.).

Speed to Market
6× faster than in-house development
This technology benefits from an already established deep learning model and clearly defined functional modules for input parameter acquisition, image processing, prediction, and output processing. This significantly reduces the time required for licensees to develop algorithms from scratch. The pre-trained model, particularly for 2D images, integrates easily with existing architectural CAD data and floor plans, enabling rapid system construction. Performance validation based on empirical data is also straightforward, potentially shortening time-to-market by approximately 2.5 years.
