Description

This product is a PDF that contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

Using wireless technologies for building controls could be cost-effective and convenient; however, traditional wireless devices required either a power wire or batteries which require maintenance as well as proper disposal. The first part of this session will discuss employing the “energy harvesting” concept as a power solution to wireless sensor networks. Self-powered wireless sensors and actuators using energy that created from slight changes in motion, pressure, light, temperature or vibration will be introduced. Research and field application examples are given to show that this technology can produce the sustainable power generation sufficient to operate a multitude of wireless sensors for building applications. The second speaker discusses a retrofit project using wireless sensors and ZigBee protocol to expand the existing direct digital control (DDC) system capability, and evaluate HVAC system performance via automated fault diagnostics and neural nets.
