Collecting measurement data in buildings enables detailed
understanding of relevant parameters for the energy consumption. Only
a detailed understanding enables fine-grained control of e.g. heating,
lighting and other energy consumption. This project uses wireless
sensor networks for massive data collection related to energy
consumption in buildings. The collected data can be used to control
energy consumption in building by e.g. optimizing heating and

One of our key interests in this project is to connect wireless
sensor networks to building automation systems. In particular,
we are interested in a protocol for building automation called
BACnet. BACnet has
a wireless
networking working group
as well as a
Swedish Interest group, BIG-SE.
Other interests include tools for deploying and managing sensor
networks in the area of building automation as well as the robustness
of wireless sensor networks in such an environment.

Publications and Articles

Impact on other NES Publications

The project has also had an impact on other NES publications:

  • The idea of multi-channel communication has been applied in this paper thas been accepted to one of the high-quality workshop in the research area (HotEmnets)
  • ZigBee is a hot topic not only for building automation and we have improved ZigBee lifetime with a factor of 10
  • We have used the convergecast protocol developed in this project to evaluate a practical simulation-based tool for network-scale power estimation (paper under preparation) and for the evaluation in another paper on sensor network configuration (paper under submission)
  • NES (almost) complete publication list

Funding of Adam Dunkels PhD thesis

The project has contributed support for Adam Dunkels PhD thesis:

  • Adam's thesis received the Roger Needham Prize that is given annually to a European doctoral thesis
    that is “regarded to be an exceptional, innovative contribution to knowledge in
    the systems area”.
  • As one of the results of his thesis, Adam also received the Chester Carlson prize


The project is funded by Energimyndigheten (Swedish Energy Agency).
