Our software, Di-BOSS™: Digital Building Operating System Solution, delivers recommendations that enable commercial building managers to make proactive, energy-efficient decisions. Di-BOSS continuously commissions data from multiple operating systems, floor-level occupancy, and ambient and forecast weather conditions. We rely on support vector regression and extremely randomized trees to model the building's thermodynamics and predict energy consumption. On top of our models, we use approximate dynamic programming to optimize operational decisions, such as when to turn on heat. Actionable data and analyses are presented in a real time control panel for building managers.
