Smart Building

Buildings of the 21^st Century will integrate the current DDC control technology with other building systems to create a "Smart Building". The Smart Building will anticipate the needs of the building users to provide improved comfort, greater user control, and better energy efficiency. Here are a few examples of how this can work:

Web based control of building systems: Building occupants can adjust room temperature setpoints, change lighting schemes, or adjust any number of other systems through a password protected web page. An instructor could use this to set up a classroom in advance of a lecture. An example of this concept, currently being used in a building at Purdue University can be seen on the web at http://205.215.64.127/pe/home
Integration of HVAC and lighting systems with security systems. A building user enters the building during "off" hours. The security system knows who has entered the building. The building then can turn on lights and HVAC systems in the areas to be used by the person entering.
Smart Windows: For most building users, operable windows are a desirable feature. Smart Windows will know if they are open and will let the building system know. HVAC systems can be automatically turned down in areas with open windows resulting in energy savings. Smart Windows combined with room occupancy sensors will alert building personnel if windows have been accidentally left open in unoccupied areas. Smart Window technology can be combined with natural ventilation schemes to tell building users when opening the windows would be a good idea.
