Abstract
The calculation of the embedded energy (EE) of twenty barns shows that there is a considerable variation of EE per cow, where the lowest values were one fourth of the highest. Use of timber instead of concrete in walls had most effect to reduce the amount of EE. Cold barns can contribute to reduce the amount of EE, while the amount of EE is higher in free-stall than in tie-stall barns.While for an existing building the amount of EE is nearly fixed, calculating the anticipated amount for a new building can contribute to reduce this value considerably. This progress can help to reduce energy use in organic agriculture and thus contribute to a more sustainable production. Incorporating EE in planning new buildings should be of special importance for organic farming, since regulations demand for more area per animal than in conventional farming. In addition to building new, renovation and extension as well as recycling of building materials should be considered. Planning a new building should also include other topics as operational energy, as well as working conditions, animal welfare and economic considerations.
