PowerPoint Presentation

Sine Building Covered Parking  
01/23/24 City Council Workshop

Site Opportunity  
2
• 17 spaces immediately 
to the south of the 
Sine Building
• 51 spaces to the east 
(Thunderbird Lounge) 
Held for Future 
Development

Project Considerations
3
• Safety lighting
• Durability and maintenance of structure
• Developing a scalable design for future city projects
• Renewable energy 
• Opportunity for use of Solar Canopies
• EV charging station(s)
• Available Electrical capacity
• ROI - Payback/Rebates associated with renewable 
energy use

Shade Options 
4
• Two provide the best durability, useful life, ease of 
maintenance and a solar option. The two options 
are:
• Solar panel shade structure with cantilever frame (I-Beam Frame)
• Non-solar shade structure with cantilever frame (I-Beam Frame)

Shade Options

Cost Estimate – 17 Spaces at Sine
Non-solar 
•
Initial Cost ~ $166,000
•
Service cost  0
•
10-Year Cost 0
Solar
•
Initial Cost                                                     ~$418,000
•
Cleaning cost : ~$1,500 per year x10 Years =  ~$ 15,000
•
10-Year potential energy savings                      ~$165,000*
•
ROI  ~15.3 years
* Savings estimate are subject to variables out of City’s  
control:
•
Power rate increase of 3% per year
•
Equipment's optimal performance without failure
•
APS credit rates are maintained throughout period
Sine building annual energy usage                        ~$21,000

Options
1) A non-solar structure
• Lower initial investment
• Smaller scale project
2) Solar structure
• Larger initial investment
• Longer time to build
• Potential payback ~15.3 yrs.
