“ How do we create an air control system that both provide
comfortable environment and lower power usage?”
Use an IOT sensor to detect power usage. Use a set of questionnaires to estimate users satisfaction
Success indicating methods
Constraint
Controlled Area
Area of interest only include the reception room at the storeThe nature of air conditioners
We can only control 2 quantities through air conditioners, which are the temperature and air speed
Data of the Mean- radiant temperature cannot be retrieved
Unable to get a hold on to a black globe thermometer.
The location of air conditionersWe cannot change the location of air conditioners
The site is mostly off-limit
Due to Covid-19 circumstance, we can only go to the site to inspect once.

The longer you work on something, the better outcome you get. Given a limited period of time, is there a method that is timely appropriate?
Time
The best method can be very costly that we can not afford. Is there a method that gives us the best value for money?
Cost
Some method might work here but not there. Is there a method that is effective in this particular place?
