Long gone are the times when about architecture andfunctionality thought separately. Over the past two decades, interior design has experienced a revolution, now there is a steady desire to take a worthy place next to the form and ergonomics. Ecological homes are becoming increasingly popular every day. Last year, the best Solar Decathlon 2014 in the USA was presented, and this year we will go to Europe to learn new events of 2015. We will start with a practical and feeling place.the decor that was created by CLEI for the two teams participating in the event. Working closely with the University di Roma Tre from Italy and with the Mexican team from UNAM, CLEI, thanks to his experience, created a universal and multifunctional design, having arranged eco houses for both participants. Italians made sure that the taste of Rome was felt on 60 squares, while the Mexicans were concerned about the issue of "clean" life in urban environments. RhOME's Ulisse Dining System combinesdesigner dining table with a pull out double bed that disappears into the wall when not in use. The table top slides down automatically as the bed leaves, ensuring that switching between them occurs in a short time. Penelope Sofa and Poppi 120 is a development from CASA. The sofa is also an attractive design that can turn from sleeping equipment into living room in seconds. CLEI plays an important role in the formation of smart (smart) furniture, clean houses and ensures that aesthetics are not sacrificed for the sake of efficiency.
