‘The project in Tallinn was outside our comfort zone and particularly appealing and interesting for that very reason. A lot of coordination was necessary for the construction of the solar system on the exterior façade. On the one hand with the engineers from K2 for the selection of the right fixings, with the metal engineers for the protection of the interior for additional support of the façade and on the other hand with the installers on site for the estimation of a stable and safe assembly,’ says Ravo Haavik, project manager at Energiapartner OÜ.
