Advisor: Cris Koutsougeras
By: Vaughn Ferrara, Ra’Najawhan Poullard, and Deuel Vaughn

2. Intro
The sustainability center is all about making the campus more environmentally friendly.
They have many methods of accomplishing this.
Solar Panels
Photo Voltaic- Solar to energy
Solar thermal- Solar to heat water
Geothermal- heat transfer of water in pond
Wind power
Build system to collect this data

3. Purpose
Our goal is to use off-the-shelf technology to design a data communication system that can be used on the existing mechanical apparatus to facilitate the data collection and pertinent controls.

4. What equipment is currently being used
Power meter Acuvim II series
Solar panels
Non tracking Photo Voltaic
Tracking Photo Voltaic
Solar Thermal

5. Where are the solar panels located2
Positions of solar panels around Southeastern Campus
Sustainability Center
Physical Plant (Tracking)
Kinesiology Building (Solar Thermal)
Biology Building (Solar Thermal) 1 3 4

6. What we have Access to:

7. Features of power meters
See real time data
Trend logging
Alarms
Waveform Capture
3 Phase or single Phase

10. Technology Non intrusive CT sensor (Current Transformer)
Similar to Voltage transformer
There are two types of CT’s, a ring core and a split core

11. Networking The Internet of Things Concept (IoT)
Wireless Sensor Networks (WSN)
Network of nodes that cooperatively sense and control the environment

12. Wireless Sensor Networks
Includes the following:
Sensor Nodes- gathers sensory information
Actuator Node- converts electrical control signals to physical actions
Gateway- Sends the data back and forth to the internet
Client- Gives users access to data

13. Things to look for in Network
Reliability
Real Time Capable
Energy Efficiency
Security

14. Networking Options Developed By: Use Markets Examples
BACnet
Modbus
LonWorks
Developed By:
ASHRAE
Modicon Inc.
Echelon Corporation/ Motorola
Use
Communication across devices
Connection between devices
Networking devices through power lines, fiber optics, and other media
Markets
Industrial, Transportation, Energy Management, Building Automation, Regulatory and health and safety
HVAC, Lighting, Life Safety, Access Controls, transportation and maintenance
Home automation, industrial, transportation, and public utility control networks.
Examples
Boiler Control, Tank Level Measurements
Tasks such as request temperature reading, send status alarm, or fan schedule
Security, lighting systems, HVAC, machine control, manufacturing, metering
Transmission Modes
Ethernet, IP, MS/TP, Zigbee
ASCII, RTU, TCP/IP
MS/TP, network, SNVT
Costs
Low; No charge for usage or licensing fees
High (proprietary); Limited users (exclusive to actual members;  mostly manufacturers)

15. Done so far
Looked at what subsystems the Sustainability already has in place
What equipment is being currently used
Researched what options were available on today's market
Research networking concepts
Looked into what other business have done similar concepts
Narrowed down what meters to use

16. This Semester Deliverables:
Finish research on the remaining software and networking devices.
Design our own system that uses newer and better technology.
Determine the efficiency of the system.
Determine how and where will we store the data.
Compare efficiency with current system at the Sustainability Center.
