    Within a greenhouse equipped with diffuse glass, cooling from above the crop, LED interlighting, active ventilation with tubes below the gutters and three screens an experiment was conducted to produce good quality roses in an energy effi cient way. After two years research the roses cv Red Naomi! fulfi lled the desired quality marks. This was achieved with less energy for heating compared to a defi ned virtual reference compartment. Combined with heat harvested during cooling there was no need for additional heating energy. The crop management was a key factor in the way to quality. For control of mildew and Botrytis it was necessary to keep the air humidity below 85 %. This is hard to achieve in an energy saving cropping system.
