The invention describes a HF-reducing green roof. This green roof comprises a support construction consisting of a layer of textile fibers and/or a substrate (), a vegetation layer () of low plants, and a flat or three-dimensional structure of electrically conductive filaments. This structure supplements the support construction or forms part thereof. The intermediate spaces between adjacent electrically conductive filaments () are smaller than one quarter of the wavelength of the electromagnetic HF-radiation to be shielded.
