 Achieving a Net-Zero Lighting System for
   the Classroom or Lab Environment

Brought to you by the students from the Electromechanical Technician program

         Gil Amdurski, Brian Li and Mark Valdmanis
                With the assistance of the Mechanical Design team

         Geodi Noble, Andrew Stuart and Kevin Lam
                            Under the supervision of

                   Leo Salemi, Professor CCET
                       And the mentoring provided by

                  David Nixon, Kortright Centre
                     Background
• 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 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
                       Methodology
The 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

                              Methodology
                  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

Control system       charging system (work in progress)
for the tracker
                       Methodology
Different light bulb technologies were tested to determine
             light level vs power consumption

                                      Comparisons were made
                                      against 4 x 25W
                                      incandescent bulbs
                                      (This is equivalent to one 4-
                                      Tube light fixture in our lab)
                      Methodology
Each bulb set was run off battery power to determine how
                   long it would last




                                 12 Volt to 120VAC Inverter

                  Lessons 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 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 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 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
TED on Google Power Meter

                  TED data can
                  be viewed via
                  an iGoogle web
                  browser
