Building automation was identified, a few years ago, as a major means of reducing energy usage in buildings. Some already installed building automation systems (BAS) have achieved between 20\% to 80\% reductions in energy cost, increased occupant security/safety, increased occupant comfort and a reduction in building operations cost. Although several building automation systems (BAS) have been installed so far, they have not yet achieved a significant market penetration nor have they successfully achieved their full potential. Several issues still remain unresolved, like:

  • increased interoperability between individual sub-systems like HVAC, lighting control etc.
  • use of wireless sensors that facilitate reduced installation/wiring cost
  • increased information sharing between the various sub-systems
  • integration with installed IT enterprise networks
  • better application modeling and deployment toolkit
  • real time monitoring and analysis

In this project we try to explore the use of WSNs for building automation. The use of sensor networks for building automation enables high-density sensing and control at lower operational costs and could therefore enable more efficient building management. Figure 1. shows an example of a WSN deployment for building automation.
