From its inception, Ortenia - Apartments in Nature aimed for the highest ecological standards. The exteriors of the apartments are made of Forestry Stewardship Council’s (FSC) certified wood, with cellulose fibre as insulation material inside the walls and fitted with natural sealing materials. The facades, clad in wood, are built using diffusion-open wall construction, allowing the building to breathe. Humidity in the interior is balanced by clay plaster
The furnishings of the apartments and common areas are of solid, untreated oak and beech wood from a Slovenian manufacturer. All the fabrics used are of natural origin, and the towels are made of organic cotton. The rooms are adorned with hand-made decorative items and accessories created by creative Slovenian designers. Water for the apartments is pumped from a depth of 80 metres. The water tank collects rainwater from the roof, which is then used to flush sanitary appliances and irrigate outside areas.
