     Towards future greenhouse concepts
     Danish research groups have
     joined to make a large leap for-
     ward in energy saving in the gr-
     eenhouse industry to meet the
     challenges of the global change
     as expressed in the global
     change summit in Copenhagen
     in November 2009.
     Greenhouse horticulture sector
     is under pressure from the huge
     energy expenses. In the last 15
     years researchers, growers and
     industries in Denmark have wor-
     ked together on decreasing the
     energy consumption. Today the
     total energy consumption is 25 %
     lower than 10 years ago with the
     same production. Compared to
     many other countries this is a suc-
     cess, but still the sector’s energy
     consumption needs to be reduced
     significantly. New technological
