A Wind Farm in the Center of Dallas

David A. Browning

Vice President of Business Services

Wind and More

• El Centro enrollment tanked at 3,500 students.

• Enrollment patterns indicated migration to suburban colleges.

• Reasons:

• congested commute to downtown area

• high cost of parking

• rising cost of gasoline

• decline of CBD as vibrant destination

1997

Structure of Program

• Eligible students

• Credit student enrolled in 6 credit hrs.

• CE students in 96 contact hrs.

• Statistics since Fall 1997

Providing Students with Affordable Transportation

• Monthly Cost of Parking

• Monthly cost of Gasoline

• % of students of FA

• No Gas $ = no attendance

• No attendance = attrition

• No Parking $ = parking tickets

• Unpaid parking tickets = jail time

• Jail time = attrition

• Affordable Transportation = student success

Public Transit Program vs. Parking

• Cost Comparisons:

• Parking Garage construction Cost $5,000,000

• 500 parking spaces (assume space cycles 25 times/week)

• Cost for Security and Maintenance $5,750,000

• Total: $10,750,000

• Est. Parkers since 1997: 221,051

• Est. $49.37 per student parker

• Total for DART-Free: $ 5,958,520

• Riders since 1997: 129,430

• $41.25 per student rider

Thin Client Project

• Overview

• Testing Concerns

• VMWare/PCoIP Hosting with DSC

• Thin Client Hardware

• Energy Savings

• Life Span of Devices

• Benefits

Energy Savings

Hardwar Savings

Expected Life Span• PCs – 3-4 Years

• Moving parts

• Subject to failure

• Thin Clients – 7-10 Years

• No moving parts

• Processing done remotely

• Pass through device only

Benefits and Advantages over PCs

• Upgrades are done virtually and remotely

• Thin Client Devices do not need to be touched individually by techs as PCs are

• PC’s do not have to be continually purchased as they age

• Multiple Profiles can be used within any classroom allowing a given classroom to serve different purposes (efficiency of use/flexibility within the classrooms)

• Whole Classrooms (or groups of client views) can be updated at once

• Substantial Energy Savings

• Security of Data

• Return on investment grows exponentially

• Faster changes to environments

• Less downtime for maintenance

How They Work• Each Turbine Starts Generating a DC current at winds of 3

M.P.H

• Maximum Power Generation is at Wind Speed of 22 M.P.H.

• Each Turbine at Peak will Generate 1 KW of power an hour

• All Turbines are Linked to a Box that converts the DC power to AC

• The AC Electricity is then Inserted Directly to the College Power System

• This Reduces the Power Needed from the Electrical Grid.

What We Have

• Four Arrays

• Twenty Turbines per Array

Payback Formula• 8,700 hours a year

• 20 Kilowatts of power Generated Per Array

• 4 Arrays

• 50% Approximate time of Maximum Power Generation

• $.055 Cost of Electricity Per Kilowatt

Or

8,700 X 20 X 4 X 50% X .055 = $19,140

Projected Payback

• Total Project Cost $240,000

• Yearly Savings $19,140

• Payback 12.5 Years

Other Benefits

• Publicity

• Used in Environmental Science Programs

• Partnership with for Wind Turbine Program

• Inspiring Student Creativity

• Reduces College’s Carbon Footprint

• Sponsorships from Private Corporations
