Estonia House Energy Balance

Similar to the Sankey diagram shown in a post last week, the below Sankey diagram also shows the energy balance of a house. Found it on an Estonian blog.

Unfortunately just a schematic Sankey diagram without figures or units. Energy “input” and losses. Looks to me like a hand drawn sketch. Valgustus is lighting, Kliimaseadmed is air conditioning, Hoone Küte is heating, and Soe Tarbevesi is warm water (thanks to Google Translate).
