FSU Utilities—Demand Side Management
Patrick Dawson, David Gonsoulin, Dallas Perkins, Matthew Streich

Project Overview
Use of demand side management techniques for energy savings in the Dirac library
Design of upgraded occupancy monitoring system
Goal is to reduce both overall energy usage and peak demand
Use occupancy data to reduce unnecessary energy usage and shift peak load

· WattStopper’s WT Ultrasonic Ceiling Sensors
· 32 [KHz] / Time delay 15 [sec] - 30 [min]
· Range of up to 2200 [ft2]
· Enforcer Curtain Barrier Sensor
· Triggers if 1+ adjacent beams are broken
· Range for indoor use of 50 [ft]
· PLC-MULTIPOINT CELESTIAL SELF-CONTAINED AMBIENT LIGHT SENSORS MK7-B SERIES
· Factory calibrated with output signal of 0-5, 1-5, 0-10, 1-10 [VDC]
· Duct Mounted Siemens QPM2100
· Measures CO2 and outputs at 0-10/0-5 [VDC] linear proportional signal
· Siemens QPM2100 duct mounted CO2 sensor

Dirac Library—1st Floor Lighting Plan

Dirac Library—2nd Floor Lighting Plan

Software
Software is run through control boxes using Siemens PPCL (Power Process Control Language)
Software will manage set points for temperature and maximum C02 levels
This level will vary based on time of day and current power output levels
Software will be used to control the environment in the building
Using the C02 level and temperature level set points, the air damper will open or close to maintain comfort levels/conserve power
Software will also be used to control the lighting, saving power
Uses light sensors to detect ambient conditions and adjust lights near windows
Use ultrasonic motion sensors to adjust lighting levels in zones
Use curtain sensors to control lighting over bookshelves
