The Swan
Ecolabelling Denmark is responsible for the
administration of the only two officially approved
ecolabels in Denmark:
•
the Swan (Nordic Eco-label)
•
the Flower (European Eco-label).
Ecolabelling Denmark is independent of
producers, brands and financial interests.
The Swan
Requirements on the indoor environment are made by
setting criteria for:
• constituent materials.
• good ventilation.
• the construction phase.
• material and quality controls to prohibit built-in damp
damage.
There are also requirements regarding impact on the
external environment covering:
• the prohibition of environmentally hazardous substances.
• energy efficiency in running the house.
• the environmentally suitable disposal of construction waste.
• a service and maintenance plan for the house.
