RESUMÉ

INCREASED OCCUPANT SATISFICATION AND COMFORT USING IoT-BASED DATA ACQUISITION FOR HIGH-PERFORMING BUILDING OPERATION AND DESIGN 

Buildings are responsible for 40% of the total energy consumption in developed countries and have a major influence on our well-being and comfort as we spend 90% of our time indoors. It is therefore crucial that we design and operate buildings that are energy efficient and provide us with comfortable indoor environmental conditions.

However, research has for many years emphasized that some buildings use more energy than originally intended and occupants are not necessarily more satisfied with expensive and strictly controlled indoor conditions as dictated by guidelines and norms. This discrepancy or “performance gap” is a major challenge that needs to be addressed and a key for understanding how to better design and operate energy efficient and comfortable buildings. Thus, the purpose of this PhD is to address the performance gap by collecting, analyzing and presenting operational data from buildings’ HVAC system, energy consumption, indoor condition and occupant behavior (feedback and use of space) to evaluate if a certain design assumption or operational process is appropriate or might be the cause of a building’s performance gap.
