2. Buildings and WSNs and March 2011
Every year , in china , new building area is 2 Billion m2.
20 to 80 percent of system installation costs are consumed by wiring.
40 percent of total energy is used for buildings , the expense of the energy source is much more expensive
WSN Applications in Building:
Continuous environment monitoring
Continuous safety Monitoring
Continuous structure monitoring
Low-cost and green
Reduce the energy expense
Without wiring requirements
Easy to deploy
Low installation and maintenance expense
Network scalability

More WSN Application Examples In Building Monitoring
Civil infrastructures monitoring using WSN
- An economic WSN organizes sensors and controllers in civil infrastructure(such as bridge , dam , airports) to monitor the structure of the infrastructure to avoid tragic happening and ensure the safety of the peoples life.
Historical building monitoring & protection
- The collected data is for a precise and quantitative understanding of the factors that may affect historical buildings , planning the preservation of such priceless treasures.
Battery Power supporting is mandatory. Expect Battery operation lasts over 1years, even longer.

Detail Example – ELC-WSN in commercial building monitoring
Extra Low Consumption Wireless Sensor Network (ELC-WSN) nodes are deployed in every floor of the building and collect the temperature, fire, vibration, humidity, light, etc. The battery lifetimes should achieve at least several months, better years.
The collected data is transmitted to the sink node and then to access point. The data will be replayed on the manager’s PC screen. So the manager can monitor the whole building environment and do some action when necessary.

Expected on tech requirements for ELC-WSN
Energy consumption
Without wiring requirement, most of the WSN devices in building monitoring should be powered by battery and the consumption current is better at several µAs.
Transmission distance
one hop distance may be ~ 100m and with good diffraction performance in indoor environment
Networking
Network must be large enough to cover the whole building.
Networking flexibility for complicated inner structure.
Networking must be easy to re-deploy and to expand as requirement. i
