Depends on many factors: Can you achieve the same level of insulation for less, by using traditional insulating materials and techniques instead of insulating bricks? Does the law mandate that your bricks have a certain R-Value? How much heating and cooling is required in the climate where the building is located? As usual there is no simple answer. Bricks are OK as an analogy, but very poor as an example: as far as I'm aware modern bricks are no more insulating than old bricks, and neither are any good at the job. If there is a modern and insulating brick, then I don't think it's really caught on very much yet.
