Wind and More
3
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
4
Structure of Program Eligible students Credit student enrolled in 6 credit hrs. CE students in 96 contact hrs. Statistics since Fall 1997 Number of Eligible Students Cost of Pass Per Semester Amount Paid to DART Passes Issued 221,051$25 - $555,958,520129,430
5
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
6
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
8
Energy Savings
9
Hardwar Savings
10
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
11
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
12
Six Years Ago An Idea Was Proposed To the President…And Then Wind Velocity Studies Engineering Studies Proto-Type Testing Meetings with Historical Board Site Line Studies New Roof – With Anchors Creation of Specification for Bid Process Analysis of Bids Design and Create Platform Coordinate installation
13
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.
14
What We Have Four Arrays Twenty Turbines per Array
15
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
16
Projected Payback Total Project Cost $240,000 Yearly Savings $19,140 Payback 12.5 Years
17
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
