NEW YORK CITY–Cortel Intel has deployed a mobile app that helps engineers control heating, ventilation, and air conditioning, saving millions of dollars in Class A buildings around the city.

The app provides information to property managers and engineers, with recommendations based on historical, current and forecasted data specific to each building. The technology takes into account the weather forecast, the day of the week, and the preceding day's profile to guide operations.

By continually monitoring and analyzing building data sources, the program helps engineers control HVAC systems. In real-time, it boils down a voluminous amount of data, providing simple charts, visualizations and recommendations, accessible through mobile devices.
