LOT 574, 576, Further the design based on approved program and & BUS LOT framework at Concept level: apply to other parking lot LOT sites* including Lots 574, 576, and the Bus Lot; Lot 560 GREEN SPACE 548; and Lot 556 LOT 556 Investigate and detail the Structural Design EAST CAMPUS improvements. Explore and illustrate Site Design improvements - on and off site. Evaluate parking lot configurations & how they relate to solar layout. LOT 548 * Note to DRB: The project scope has evolved. CU Staff has since directed the design team to proceed with Lot 560, Lot 576 & the adjacent Green Space to obtain the solar production needed.

GOALS
7 - PROJECT GOALS: Study Lot 560, Lot 576 and adjacent Green Space to maximize solar energy production at this location to help meet the campus goal. Accentuate the Visitor experience at Lot 560 with an aesthetic solution to highlight entry. Prioritize design & structural honesty. Tie design elements to CU campus precedents. Integrate pedestrian circulation & improve ADA access to buildings. Incorporate temporary bus parking & emergency vehicle circulation. Manage floodplain requirements, grading & drainage, and existing utilities. Provide appropriate cost-benefit ratio.
8 - - 8 PROJECT GOALS: 4 MW (DC) Campus Capacity Goal Indicated by NREL REOpt Study SOLAR ENERGY GOALS: (from current 1.3 mW) CU has a 4 mW goal for campus (4,000 kW) $0.13 per kWh Target PPA (hard + soft costs) Currently CU has 1.3 mW of solar tied to the microgrid
VARIED 2.5-3.0 mW range acceptable O R I E N T A T I O N S

SOLAR DESIGN
28 - SOLAR DESIGN: PARAMETERS STRUCTURAL PARAMETERS
5.0O IDEAL ANGLE To minimize cost and maximize modularity, parking layouts set structural parameters.
Provide structural design for 3 solar carports, based on parking layout.
Solar provider to finesse final application of solar modules onto optimized structural
concepts.
STANDARD CLEARANCE 7lb/ft2 Snow Load: Structural & PV Recommendation (within local code of 30lb/ft2)
Wind Uplift: 155 MPH local code requirements for structural capacity. 5 degree slope SOLAR PARAMETERS reduces wind uplift.
At Colorado’s latitude, the steeper the slope, the better the generation (kW-h/kW), Maintenance: but increased environmental loads. The ‘ideal’ is to identify a preferred configuration • Bird Deterrence - Tube Steel Preferred. (kW) and then maximize for generation kW-h/kW). • String Inverter - mounted on poles or pad mounted nearby, or potentially below roof of structure. South-facing solar is the most productive, followed closely by east/west-facing. • Owner must commit to snow plowing and occasional asphalt maintenance below structure. At slopes below 7.5O, the greatest structural economy is achieved.
