Cost- and Energy-Efficient Control Systems for Buildings

This project exploits high resolution data gathered in KTH Live-in Lab research test-beds through an advanced, modular and flexible monitoring set-up capable to acquire real-time data on indoor environmental quality and the involved energy flows including ground source heat pumps, photovoltaic panels, ventilation. It will provide an assessment of the inefficient energy use of common faulty systems and guidelines for cost-optimal design and for implementation of building monitoring and control systems.

Methods and demonstrations to move towards intelligent and smart buildings are needed. Monitoring data is currently collected without exploiting the inner potential for innovative solutions. This is typically due to, among other reasons, the lack of efficient and dedicated sensor network design and data structures.

What sensors is it necessary to install? How should the database be conveniently structured? What is the most cost-effective solution for smart monitoring and control one should adopt for a building?

Recommendations for a cost efficient implementation of monitoring and control systems depending on the building and the energy supply system characteristics are strongly necessary but not yet available as common practice.

Both new and existing buildings are lacking comprehensive guidelines and demonstrations about the impact on the energy use of faulty settings. Consequently, the opportunities for enabling the energy saving potential of ICT solutions are still locked and the system maintenance is also negatively affected.

Project description

In order to overcome these gaps and limitations, databases of monitored data with high resolution and reliable quality can lead to new valuable insights and the creation of new opportunities. Research test-beds offer unique resources to develop and test smart monitoring and control solutions that have a valuable impact on increasing the energy efficiency in the built environment. This project will exploit the high resolution real-time data gathered in the KTH Live-in Lab research test-bed through an advanced sensor and data infrastructure in order to evaluate the cost-effectiveness of smart buildings. As a result, the operative definition of smart building will be enabled. The project will exploit the existing sensors to identify common faulty settings in buildings’ ventilation and heating systems, estimating their impact on the energy use. Particular attention will be dedicated to the user experience, the impact of the users on the energy use and in visualization techniques to promote energy efficient behaviors.


Three building facilities will be used as implementation and prototype sites: the KTH Live-In Lab Testbed KTH, the Undervisning Hus and the neighborhood of Uppsala Backe. The first round of data analysis will be carried out in the Testbed KTH and Undervisning Hus; this will help identifying the room for improvement in both buildings and it will support the design of the ICT infrastructure in Botrygg’s Uppsala Backe.

Primary areas of investigation are:

  • Monitoring, Data analysis and Fault detection

  • Control Approach Evaluation

  • Analysis of Technical and Economic Opportunities
