We are introducing a new AI-based comprehensive product which includes a big database on energy data and renovation materials, an AI-based energy model, web-based platform, a linked app, and a sustainability meter. This model is very beneficial for energy auditing, commissioning and re-commissioning of buildings in terms of proving highly accurate results with detailed information in a very short period of time. This model also can be applied for financial planning of new construction project or building maintenance by considering life cycle cost, payback period, and governmental incentive programs. In addition, it could be used as an essential part of sustainable building certification (LEED, BOMA, Energy Star, etc.) when it comes to preparing a particular energy, cost, and environmental compliance report.
