Description: Greenhouse gas and ammonia emissions of dairy barns are effected by a multitude of factors such as weather conditions, barn design and its surroundings. Consequently, emission factors derived from measurements in a handful of barn systems might not be representative for the broad range of existing barn types, even within a specific region. Due to the current legislation in Flanders, which is based on the use of average emission factors, this could lead to negative consequences for farms that might actually perform much better than the average farm. Or, allow farms to produce significantly higher emissions, due to poor management. The idea of continuous online monitoring is, therefore, gaining more interest. Ideally, each barn would have its own climate and emission monitoring system, allowing farmers to adjust their management towards better indoor climate and lower emission levels. However, one of the biggest hurdles hindering progression towards such systems is the large cost of accurate NH3, CH4 and CO2 sensors. ILVO has equipped its full scale dairy barn with state of the art emission measuring techniques. These high-end techniques will act as a reference for the different ?low-end? monitoring systems that are being developed. The insights into the application range and cost/accuracy balance of a distributed sensor network containing affordable sensor nodes will be discussed.
