Demand controlled ventilation systems for energy efficiency and good indoor climate – Equipment and system requirements

This project is a cooperative research effort by Chalmers University of Technology, Sweden, the Danish Building Research Institute, the Norwegian University for Science and Technology and also VTT Building and Transport, Finland and initiated by the Nordic Innovation Centre. The overall object of the project is to disseminate technology about demand-controlled ventilation and show its potential for benefiting its users' health, comfort and productivity and moreover to result in reduced energy bills. It is also an object to focus on new opportunities for doing business for manufacturers, consultants and construction companies. Specific objectives are: 

• Overview of sensor technology, factors that contribute to describe needs, IEQ, indicators and their application in the field of demand-controlled ventilation
• New opportunities with sensor and information about their performance and suitable location
• Information about the performance of the installations and the relation between indicator values and perceived IEQ
• Possibility of implementing demand-controlled ventilation systems in a number of case studies
• Documented result of the implementation of 3 demand-controlled ventilation systems
