Alamosa Map
Public Input (with impacts on costs) Not too big (over 600 students) Save both district and parent transportation Improve staff utilization Use the sun Save operation costs
One Site with Connected “Pods”
One Site with Two Schools
Two Sites for Two Schools
Site Plan
New Remodel/Existing Staff sharing Fewer bus drops
5>3 Transportation
4-day school week Transportation Some Staff
Consolidation Increase faculty
utilization Transportation Staff
Learning Recissions required staff reduction earlier
than planned, but done with new school savings in mind
Site selected didn’t allow transportation savings Due to railroad and highways More students to bus Looking at 2-tier bussing (MS/HS and ES)
Impacts offsite need to be pushed forward and in writing

Xcel Energy Programs
Wray School District Wind Turbine The District was spending approximately
$80,000 a year on electricity They were challenged to find new ways to
create additional revenue streams for the district
They thought a wind turbine would be a perfect way to decrease spending and provide educational opportunities for students
On the eastern edge of Colorado, the average wind speed at the site is estimated to be 18 mph, and the turbine is expected to produce about 2,700,000 kilowatt hours (kWh) of clean energy per year
Through a combination of Energy Impact Grant, local pledges and pre-selling of renewable energy credits (RECs) they were able to finance the project
Xcel Energy Programs Energy Design Assistance
Xcel Energy business customer Project size greater than 50,000 SF Project status before or during “schematic
design phase” Will to consider design options to save energy Commitment to achieve minimum of 5%
demand savings for “Basic” program and 16% savings for “Enhanced” program
Xcel Energy Programs Services
Free energy modeling (~$30,000 Value) Cash rebates of $300 per kW and $7 per
decatherm Design fee reimbursement up to $12,000 “Enhanced” program includes additional
modeling such as daylighting and free calculation for LEED Energy and Atmosphere credit one
Xcel Energy Programs Energy Efficient Buildings
Prescriptive approach to achieve rebates For new construction, major renovations and
additions Project size smaller than 50,000 SF
Services On site verification to review installed
strategies Rebate amounts vary according to equipment
purchased and installed Non-prescriptive measures are up to $400 per
kW and $7 per decatherm
Xcel Rebate Example at Sargent Owner selected several
energy conservation strategies
Projected energy cost savings of over $72,000 per year
Xcel is providing a cash incentive of approximately $42,000 which will result in a simple payback of 9.4 years

Energy Modeling
This allowed us to test the economics of various energy efficiency strategies
Created energy model of the existing Alamosa Middle School
Energy Modeling Evaluate replacing the existing light fixtures
Replacing the antiquated fixtures with newer technology saved 83% in electrical energy.
However, reducing the heat generated by the lights increased the building heating costs by 30%
It’s critical to look at the big picture – all the inter-related building systems
Xcel Rebate Example Replace existing light fixtures – middle school
example More efficient models will result in a reduction
of electrical demand in the amount of 237.6 kW
Xcel offers an incentive for reducing lighting demand ~$400 per kW
This example is a rebate of ~$95,000 which would finance more than 50% of the replacement costs
Additionally the District would save 768,000 kWh of electrical charges per year
Energy Modeling Evaluate upgrading the roof insulation
R-4 roof insulation to R-30 Energy savings on 3.5%
