| Essay:Building envelope research: wireless sensor network (WSN) and applications in buildingsWireless Sensor Network (WSN) and applications in buildingsWith the advance in measurement technology since mid-80s, sensors can go on wireless and on the networks. A few references are added to this database on the general topic of measurements and building/constructions. Other sysmtems include: power line communication (PLC, X-10), bus line communication and radio frequency (RF) communication.
"A sensor network is composed of a large number of sensor nodes, which are densely deployed either inside the phenomenon or very close to it. ˇWireless communications, and digital electronics have enabled the development of low-cost, low-power, multifunctional sensor nodes that are small in size and communicate untethered in short distances. " in this paper by Akyildiz, I. F., Su, W., Sankarasubramaniam, Y. and Cayirci, E., 2002, Wireless sensor networks: a survey made a survey of the wireless tech. They envisioned a few application areas that included Home Automation. Jang et al., 2008, Wireless sensor networks as part of a web-based building environmental monitoring system presented details of a web-based system.
Why use wireless, "Additionally, estimates of the cost to run signal wire in 2002 ranged from $2.20 per meter for new construction to $7.19 per meter for existing construction [3]." M. Kintner-Meyer and M. Brambley, Pros & cons of wireless, ASHRAE Journal 44 (11) (2002), pp. 54-61. Kintner-meyer and Brambley, 2002, Pros & cons of wireless.
Jeong, J., Firrantello, J. and Freih, J. D., 2008, Feasibility of wireless measurements for semi-empirical multizone airflow model tuning mentioned the advantages of WSN "portability and flexibility, fast equipment setup, time synchronized data collection, negligible interruption to the occupants' activity during the measurement, and installation time and cost saving" (applied to improve/tune multzone airflow network model. They presented a working system, and cost analysis, in the actual dollar term for WSN. Oksaa, P., a, M. S., Sydenheimoa, L. and Kivikoskia, M., 2008, Kilavi platform for wireless building automation presented a particular platform to implement WSN for building control and monitoring. They placed WSN as part of an intelligent building. "Kilavi is a wireless manufacturer-independent platform for building control and monitoring--low data rate control and sensing providing the functions and messages for the implementation of functional and reliable building automation system that can be controlled through a common interface.." Wu, S. and Clements-croome, D., 2007, Understanding the indoor environment through mining sensory data:A case study focused on analysis of data from WSN (and special issues related to WSN data, such as reliability | ||||||||||
