Approaches and Properties for Aggregating Occupant Preferences

Maintaining comfortable thermal conditions in an office environment is very important, as it can affect the quality of life of the occupants, their work productivity, and improve energy efficiency. One significant aspect of this task is how to balance the preferences of a number of occupants sharing the same space. We suggest three families of approaches to this problem, both for the case of optimising for a single time period, and for the problem of optimising over multiple different time periods. We analyse in detail the different approaches based on a number of natural properties, proving which of the properties the different families satisfy.
