Achieving a Net-Zero Lighting System for Achieving a Net-Zero Lighting System for the Classroom or Lab Environmentthe Classroom or Lab Environment
BackgroundBackground
• This project was a spin-off from the primary research project at the Kortright Centre and the solar tracker installed on the roof at Casa Loma
• The objective was to determine whether it is possible to collect and store enough solar energy to power the lights in a lab or classroom without the use of hydro
• The solar tracker installed on the roof would be used to produce the electricity, an intelligent switching battery bank was designed to store the energy
Research ObjectiveResearch Objective
• Use solar panels from the roof to charge a battery bank
• Convert the stored energy to power the lights in the lab
• Test various light bulb technologies to determine most efficient bulb that can run off batteries
MethodologyMethodologyThe solar tracker was designed, built and installed on the roof of
Casa Loma Campus as part of the main research project to collect the solar electricity required for the battery system

MethodologyMethodology
Brian Li• Set up all the manual controls and ran all the wiring
from the roof to the lab• Built the switching circuits for battery unit
Gil Amdurski• Worked on the automatic control system for the
tracker
Mark Valdmanis• Assisted with the software development and data
acquisition system• Tested the various bulb technologies
David Nixon, Kortright Centre• Provided insite on how to build an intelligent battery
charging system (work in progress)Control system for the tracker
MethodologyMethodology
Comparisons were made against 4 x 25W incandescent bulbs (This is equivalent to one 4-Tube light fixture in our lab)
Different light bulb technologies were tested to determine light level vs power consumption
MethodologyMethodology
Each bulb set was run off battery power to determine how long it would last
12 Volt to 120VAC Inverter

Length of time on one battery charge
Incandescent 100 Watts 100 Watts < $1 Low 1 hour
Compact Fluorescent
100 Watts 30 Watts $3 - $4 Good 3 hours
LED (Round Bulb)
100 Watts 35 Watts $30 Best 3 hours
LED (Strip) 110 Watts 12 Watts $25 N/A N/A
Halogen 100 Watts 100 Watts $5 Brightest To be tested
Lessons LearnedLessons Learned
To run the four fluorescent fixtures in the lab 24 hr/day using solar power we would need:
3 - Solar Panels (total 500 Watts)1 - DC to AC Power Inverter (and 377 V transformer)1 - Battery Bank System (4 Batteries @ 100 AHr per battery)
Cost to run 1 small room < $5000 (worse case)
Lessons LearnedLessons Learned
Recommendations to optimize the efficiency and reduce costs
• Switch to a LED light bulbs• Incorporate an intelligent charging system for
battery bank (use David Nixon design)• Use Building Automation technology to control
the lighting system only when room is occupied
Future ResearchFuture Research
• Join the EMerge Alliance to learn more about the proposed DC infrastructure standard for lighting systems
• Set up an energy monitoring and building automation system (See TED example)
TED Live DashboardTED Live Dashboard
TED can display real time data or store data for later retrieval
It can monitor different loads at a time e.g. stove, fridge, HVAC
Easy to install for around $200
