Incorporate Energy Saving Methods to the Escalators

Determine the energy specifications of the motor of the escalators Determine the energy usage of a single-span escalator Determine the average amount of energy saved (per day? Per month?) ~all within the next month

Create a diagram/model representing the energy saving technology (E-save Motor Controller) while in use at the science centre On the model, I want to inform visitors the technology being integrated into the escalators themselves ~ model will include a large informational poster/display placed on the wall next to the escalator, so as visitors are traveling between floors, they can read about the methods being used.

No budget will be needed for this

How E-Save tecnology works: http://www.powerefficiencycorp.com/technology.php

Power Efficiency Corporation is a green energy company focused on efficiency technologies for electric motors. Power Efficiency is incorporated in Delaware and is headquartered in Las Vegas, Nevada. The company has developed a patented and patent-pending technology platform, called E-Save Technology™, which has been demonstrated in independent testing to improve the efficiency of electric motors by up to 35% in appropriate applications. Electric motors consume over 25% of the electricity in the U.S. and many operate inefficiently. E-Save Technology™ can be licensed to motor, controls and equipment manufacturers. Power Efficiency’s first product based on E-Save Technology™ is a Motor Efficiency Controller for applications such as escalators, crushers, granulators, mixers, saws and MG elevators. Power Efficiency is also developing a new product based on E-Save Technology™ for the tens of millions of small motors found in applications such as residential air conditioning, pool pumps, and clothes dryers. The company is working with manufacturers to incorporate this technology directly into new motors and appliances.

**Technology outline & how it can save energy:** The energy optimizer (also known as performance controller, energy saver or power factor controller) is a solid-state controller that reduces losses in AC induction motors in the form of energy efficiency and soft starting capability. It is not a variable speed drive and does not change the frequency of the motor. **During the low load condition, induction motors usually operating at full supply voltage have very low power factor and are less efficient. The energy optimizer could provide the required motor operating voltage to suit various loading conditions **, resulting in power factor improvement and reduction of motor losses. The other benefit of the energy optimizer is its soft starting property that reduce motor starting current and excessive wear of mechanical gears, chains, belts etc. associate with the mechanical transmission system. The energy optimizer could be use for any AC motor application with constant speed and variable load. Best applications are those motors with substantial variation in loading such as escalator and passenger conveyers. An energy optimizer

Service-on-Demand Escalator http://ee.emsd.gov.hk/english/lift/lift_tech/lift_tech.html#3 Includes "automatic start/stop control" technology of these sensors seem to be expensive>>will energy savings pay off the price of installing this technology? Consider the amount of escalators found in the science centre.

Contacted building maintenance to determine the energy specifications of the motor in the escalators.

Escalators we have>>large

Contacted building maintenance to see whether they knew the energy specifications of the motors of the escalators ~emails received saying they have information on escalators>>need to get back to them

Read Tony's idea of making a display in the main hall, and thought about integrating a display right into the walls next to one of the escalators displaying the possible energy savings if the E-Save motor controller were used

Oct 30

Contacted KONE service center email directed to Toronto branch-waiting for response

I believe the licenses of the escalators are under John Bradshaw's name, from the Department of Facility Services. directred to contract Lynn Row, as Bradshaw is out. waiting for response.

Contacted Roger Mercer>> there are already motor controllers in the escalators== Informed that they are upgrading the lighting system by programming it into the BAS lighting system

Nov 14

>>> modify goal--inform visitors of energy saving methods already being incorporated through informative displays, similar to what stated before:

integrating a display right into the walls next to one of the escalators displaying the possible energy savings if the E-Save motor controller were used Waiting for Mr. Mercer to send information >mid next week No reply==

Talked to Tony about amalgamating ideas. Change of goal>>>inform visitors of what changes are being made now, and what can be currently incorporated into the Science Centre.

Decided to take on designing the displays that demonstrate the ideas and information that the group collected. Began by creating the logo that will be used on the displays, as well as the main format, colour scheme, etc.

Logo







Example of how to incorporate designs. Only half of the proposed escalator design.

Different colours for every idea

Tony's will be yellow~fitting for the information he's displaying.

"DID YOU KNOW: You produce 55mJ walking through the Piezo-Power Gate" "ENERGY TIP OF THE DAY: Turn off the lights"

2 other labels will be up by tomorrow morning.
