Hi Yu, just an idea, I've had clients ask me how to make their existing building cooling systems more energy efficient. So perhaps if you make a series of retrofitting and modernizing old systems to be more energy efficient that'd be helpful. For example, can retrofit the old AHU with EC fans, also afterwards showing how to calculate new efficiency all this. From our malaysia/singapore POV. Thanks in advance
