Occupant Behavior and Comfort

  Copyright: © EBC

Our vision is a comfortable and healthy indoor environment with HVAC technology, which focuses on the occupant.
We acquire new knowledge to improve practical applications by means of simulations, measurements, subject tests and field studies.

The interaction between an occupant and the HVAC system, windows, lights, etc. has a big influence on energy demand during dimensioning of a system and therefore on energy consumption during the operation phase. We analyze measurement data from field tests with regard to occupant behavior. A main aim of this analysis is the development of stochastic behavior models to extend system simulation models.

In the field of comfort, our team focuses mainly on thermal comfort and air quality.
Besides energy efficiency, achieving a well-defined level of thermal comfort in indoor environments is a main goal of HVAC systems. Typical examples of indoor environments we investigate are residential buildings, car cabins, and aircraft cabins. The main methods we use regarding thermal comfort are measuring comfort-relevant parameters, the evaluation of sensation and comfort by a test panel, and simulations with thermal comfort models.
Another crucial parameter for comfort in indoor environments is air quality. Good indoor air quality and the impression of fresh air are important requirements for the health and well-being of occupants in indoor environments. Important influencing factors in terms of air quality are emissions from interior materials and from the occupants themselves. In our air quality laboratory we do subject tests with trained and untrained subjects regarding different hedonic parameters.
