It all depends on how you look at it, but to consider its economics you may look at the following.
Dead weight of AAC blocks on structure compare to normal bricks.
Speed of construction and how fast you wish to build a project.
Workmanship and defect levels in executed work - smaller the size, higher can be defect level.
AAC blocks can be fixed with adhesive which does not require curing and normal bricks cant be done in that way till now unless the design of normal bricks is changed.
Wastage level and its utilization.
heat resistance
sound insulation
Environmental consideration
CO2 emission
natural resource wastage's
and there are many more factors which can be considered while calculating economics and factors are base on the need.

Totally agree with Mr Deshmukh
For large multistory building if we use AAC block in place of normal bricks it will reduce dead load thus the sizes of all structural member will reduce and this may be cost effective.
As well as in brick work normally thickness of plaster is more due to unevenness of brick while in AAC block plaster thickness is less this will be cost effective.
But overall we have to check quantity of work and real project requirement.

Burnt clay brick is a predominant construction material used in construction. The CO2 emissions in the brick manufacturing process had been acknowledged as a significant factor to global warming. Therefore, now- a-days we should focus more on seeking environmental solutions for greener environment. To fulfill this objective, new construction materials can be used for construction. One such material i.e.,
AAC blocks can be used as an alternative material for construction. The comparative statistical analysis of cost effectiveness of using AAC blocks instead of traditional red bricks. The usage of AAC blocks gives a prospective solution to construction industry along with environmental preservation. An attempt has been made to compare AAC blocks as a replacement material to red bricks.
The different types of tests were performed to determine various properties of AAC blocks as compared to others. The 6” and 9” thick wall building were designed using Staad pro software and the cost calculation for different component parts of the building were carried out. From the experimental results, it is observed that the compressive strength of AAC block is comparatively more than traditional bricks and the density of AAC block is comparatively less which helps in reducing the dead load of structure. It is found that upto 15 to 20% , the cost of construction can be reduced by using AAC blocks.
