After four busy years with six official meetings in person, involving up to 15 international experts from six different European countries, the VERA test protocol \u2018Housing Systems\u2019 has been thoroughly revised to reflect the latest state-of-the-art.<\/p>\n
As dairy farms are coming into focus in terms of ammonia emissions, the challenge of measuring in naturally ventilated animal houses shows up more frequently, and several VERA verification processes are targeting this application area. At several scientific conferences last year, the presentation of this work repeatedly caught the interest of the auditoriums.<\/p>\n
Now, after final approval of the VERA Board, it is ready for publication. We are glad that the revised version, with all its detailed descriptions and recommendations, is now available for free download on our sub-page \u2018test protocols\u2019.<\/p>\n
For your convenience, it comes with an Excel spreadsheet <\/strong>that provides detailed equations, including some assumptions for the calculation of the emissions when using tracer gas measurements.<\/p>\n This revised document was drawn up by nominated international experts of the International VERA Committee (IVC) for Housing and Management Systems and especially competent guests:<\/p>\n IVC members:<\/p>\n Julio Mosquera Losada, WUR, the Netherlands<\/p>\n Nico Ogink, WUR, the Netherlands<\/p>\n Anders Peter Adamsen, SEGES, Denmark<\/p>\n Bjarne Schmidt Bjerg, University of Copenhagen, Denmark<\/p>\n Peter Kai, Aarhus University, Denmark<\/p>\n Eva Gallmann, University of Hohenheim, Germany<\/p>\n Eberhard Hartung, University of Kiel, Germany<\/p>\n Ewald Grimm, KTBL, Germany<\/p>\n Guests:<\/p>\n Peter Demeyer, ILVO Vlaanderen, Belgium<\/p>\n Paul Robin, INRA, France<\/p>\n M\u00e9lynda Hassouna, INRA, France<\/p>\n Sabrina Hempel, ATB Potsdam, Germany<\/p>\n Brigitte Eurich-Menden, KTBL, Germany<\/p>\n Ulrike Wolf, KTBL, Germany<\/p>\n Sabine Schrade, Agroscope Taenikon, Switzerland<\/p>\n
