Council Directive 2006/112/EC must be interpreted as meaning that, in circumstances such as those at issue in the main proceedings, in which a taxable person has had a building constructed and has sold that building for a price less than the cost of constructing it, that taxable person is entitled to deduct all of the value added tax paid in respect of the construction of that building, and not only a part of that tax in proportion to the parts of the building which its purchaser uses for economic activities. The fact that that purchaser allows the building at issue to be used without charge is of no importance in that regard.
