Excerpt: "The main idea of the workshop was to gather the opinions and ideas amongst the workshop participants about personal control over indoor climate and user behaviour. The workshop followed the introduced program reporting in details below main results and discussions."
Sample: 1 of 15 topics addressed
Statement #1. We know how building occupants use their adjustable wall-thermostats and other controls
The majority of the participants disagreed (90%). Examples given to prove that we still have limited knowledge about the use of controls (specifically adjustable thermostats) were:
· In open-plan office buildings occupants may not adjust the thermostat as they believe that the uncomfortable thermal sensation is too subjective and an adjustment may cause complaints between colleagues. Additionally, it seems a common experience that many people (notably women) do not have a good idea of the functionality of control devices.
· Residential buildings: the family often compare the use of the thermostats with the direct contact and perception and as a consequence they may adjust it wrongly. In fact, often people react to the instant thermal sensation because they do not know the functionality of the HVAC system that is behind the control tool (it is not explained to them how the system works and how they can adjust it).
An additional opinion between the audience also raised the problem that often we don´t know where the thermostat is located and what it is really measuring. In fact, often it is attached to a wall at a very high place resulting in measuring some air temperature that is very different than the one perceived by the occupants (as proved in scientific studies).
Suggestion on the use and intrinsic logic design of smart phones was given for the HVAC professionals in order to use their knowledge and their experience to provide and adjust the environmental thermal conditions.
