This School relies on analysing Qi that resides in a building as a result of the complex interplay between timing, landforms and attributes of the 9 stars of the Big Northern Dipper. Again, the reference point has to be the location and direction of the building.

One is required to work out the Star chart of a premise to ensure the external and internal and environment matches the favourable and unfavourable Qi that permeates the building.

The complexity in this method is due to the need to analyse a number of stars at the same time, know when they are the strongest and when weakest, where strength of effect is in part dependent on the Life Gua of the occupants.
