Visitors study a house-shaped display on artificial grass marked "R290", showing a radiator, a white wall unit and a storage tank, with labels for "Solar Panel", "Battery", "Grid", "I-Cloud" and "Radiator". In the background, split air conditioners and an "A+++" sign hang beneath a forest graphic in the meeting area.
