To all my floral design friends and event planners... don't you wish this was your flower market?! I do! Via Inhabitat I was whisked away to Barcelona to discover Mercabarna-Flor, an energy efficient and totally design-savvy flower market designed by Willy Mully Architects. The plant market acts as a greenhouse to grow potted plants and its climate is very carefully regulated with both radiant heating and passive cooling - one of the biggest systems of its kind. Passive cooling helps to introduce humidity and ensure that temperatures stay between 15 and 26 deg C. Meanwhile the radiant industrial floor ensures that the flowers have enough warmth to grow.The zinc roof and walls are covered with geometric patterns, intended to evoke an aerial view of cultivated-flower fields. A multicoloured band of striped panels wraps around the structure. The building contains three different markets selling cut flowers, plants and accessories. It also includes offices, two floristry education centres, an event space and parking.
