The "expensive venetian blind" looks to mitigate radiant heat transfer into a room through a window.  The sliding blinds consist of 2 materials, one to reflect heat/light and one to absorb heat/light. Each louver rotates and slides to different positions.  An operative example would be to reflect direct sunlight out during the day when it's warm then absorb late day light, rotate the blinds to face inward after sunset, and radiate the absorbed heat into the room.
