In order for buildings to be sustainable from an operational point of view, the basics are to save energy and maximize efficiency. This is only possible with the availability and around the clock collection of real-time data for energy use. These data can be collected via sensors installed all around the building which then feed back to the building management system or to the occupants. Transmitting data and powering those sensors remains a challenge. With today’s wireless technologies and microcontrollers, transmitting is well developed, however, sensor power sources are still in the developing stage. This work describes the testing of Thermoelectric Generators (TEG) at the ultra-low temperature difference level (5oC and below). TEGs are used as energy harvesters that make use of the temperature difference within the building energy systems, to power wireless sensors, thus eliminating the need of a battery and the maintenance/operation costs that come with it.
