Q ZY studio, a reused vineyard barn, is a new personal design office located in San Francisco. The lighting concept of this building is to create a forward & organized design space: combing daylight and different electrical lighting techniques to generate unique and clean perception. The custom ceiling panels with LED strips inserted in middle serve as main ceiling part in reception & waiting area. Ceiling panels with irregular length work with LED strips to provide indirect lighting and serve as a whole to provide illuminated "hanging-flag" perception. A large side window invites sufficient daylight during day time to save electrical energy and provide warmth in winter. Sunlight working with custom ceiling panels casts scattered shadow on floor, by which increase stimulation and clients' satisfaction. A window shade is applied for thermo concern. Upward wash light is used at bottom of reception desk to highlight marble texture. Forward & organized lighting is further incorporated into crack ceiling on second floor. LED edge lights inserted in crack ceiling panels to create forward and unique feeling. Crack ceiling panels are set at same ceiling height and color so that a sense of organization is improved. LED edge lights are dimmable to save energy during daytime. LED edge lights are also applied on back wall to accent triangle shapes. Three large side windows with shades are added to invite daylight for further stimulation.
