WP 4 - Active Systems

 The overall objective of the project of ensuring a high quality indoor environment, in the present Work Package is approached through the analysis of the HVAC and lighting systems.

 Human thermal comfort is defined as the state of mind that expresses satisfaction with the surrounding environment. Maintaining thermal comfort for occupants of buildings or other enclosures are therefore one of the important goals of HVAC design engineers. Indoor thermal conditions are important for health and comfort, although individuals vary in their temperature requirements. 

 At the same time artificial lighting influences human biological needs, for example, interfering with melatonin secretion at night and modifying human level of attention and brain response. Dynamic lighting systems are, thus, of primary importance for the quality of indoor environment. 

 These active systems are based on three basic components, a sensor system that monitors the physical parameters associated with the different phenomena, a control system that analyzes data from the sensors and, based on specific control algorithms, manages the active component. 

 The work package activities will focus on the definition of the optimal active systems control algorithms,
particularly in relation to energy-efficient buildings:  
  • Definition of optimal operational methodologies and control algorithms for lighting
  • Definition of operational methodologies and control algorithms for HVAC systems
  • Definition of operational methodologies for a Plant Based air quality control, to be integrated with HVAC system.
  • Design, development and validation of an Intelligent Control Platform able to implement the operation methods and the control algorithms developed within the Work Package.
