Buildings are among the largest consumers of electricity. A significant portion of this energy use in buildings can be attributed to HVAC systems used to maintain comfort for occupants. In most cases these building HVAC systems run on fixed schedules and do not employ any fine grained control based on detailed occupancy information. 

One of the key issues for realizing the smart building/ home is how to detect the locations of residents. Not all areas of a building are created equally. Some parts may flurry with activity at one time of the day and be virtually unoccupied during others – meaning money is being wasted when an HVAC uniformly heats or cools a building that doesn’t have uniform occupancy and usage. A common theme seen in energy conservation strategies is the capability of the HVAC system to respond variably to a dynamic demand. In particular heating, cooling and ventilation systems, which account for between 30 and 40% of the EU’s annual energy consumption must be made more efficient. Evidently the capability of the system to respond to variable conditions is tightly bound to its ability to actually sense these variable conditions in the room as accurately as possible. More in particular, people detection, counting, localization and accurate knowledge of the temperature distribution inside the room are key control variables. Infrared sensors detect and measure changes in position, direction and temperature and are thereby a perfect indicator for occupancy. 

Panasonic started the infrared array sensor business with its innovative 8x8 thermopile array sensor called Grid-EYE. Grid-EYE is an infrared array sensor and the first ever 64 pixel IR camera in an all-in-one compact SMD package. It has 64 thermopile elements in an 8x8 grid format that detect absolute surface temperature without any contact. Unlike conventional sensors, Grid-EYE uses a patented 60° silicon lens etched out of a silicon wafer, which is the smallest available lens in the market. Based on its advantages in comparison to thermopile and pyroelectric sensors we will present case studies and discuss benefits of this technology.

We are looking forward to seeing you there!
