Solar-Cooled Dugouts for Youth Baseball in the U.S. Southwest

Project Proposal: Solar-Cooled Dugouts for Youth Baseball in the U.S. Southwest
1. Introduction & Problem Statement
Youth sports in the U.S. Southwest—especially baseball—are typically played during late spring and early summer, when temperatures routinely reach dangerous levels. Due to climate change, average temperatures across Arizona, New Mexico, California, Nevada, Texas and surrounding regions continue to rise, increasing both the frequency and intensity of extreme heat days. Young athletes are especially vulnerable: children generate more metabolic heat relative to body mass, sweat less efficiently, and acclimatize more slowly than adults. As a result, they face significantly greater risk of heat exhaustion, heat cramps, dehydration, and, in severe cases, heat stroke.
Baseball dugouts provide minimal environmental protection. Most community and youth-league fields use partially enclosed concrete or chain-link structures covered by simple metal or shingle roofs. These structures provide shade but generate a “heat cavity,” where radiant heat, low airflow, and reflected surface temperatures create conditions often hotter than the surrounding field. As temperatures rise year after year, the existing dugout design no longer provides acceptable protection for youth athletes.
Forecasts for the Southwest indicate continued warming in spring and early summer, meaning this safety challenge will intensify over time. Without engineered mitigation, players waiting their turn in the dugout remain at high risk for heat-related illness during practices and games.

2. Project Objective
This Senior Engineering Capstone Project aims to design, prototype, and test a solar-powered cooling system integrated into a youth baseball dugout to reduce heat stress on players. The solution must be off-grid, cost-effective, structurally safe for community facilities, and suitable for the hot-arid climate typical of the Southwest.

3. Concept Overview
The proposed design uses roof-mounted photovoltaic (PV) panels that provide two simultaneous benefits:
1. Passive cooling through shade
The PV array replaces or overlays the roof, significantly reducing radiant heat load.
2. Active cooling using solar-generated electricity
The PV output powers one or more cooling subsystems inside the dugout, such as:
o High-flow DC circulation fans
o Fan-and-misting arrays
o A compact solar-powered evaporative cooling module (optimized for arid regions)
o A hybrid system that activates cooling only when players are present
Water use (for misting/evaporation) will be managed carefully through a low-flow pump, optional small reservoir, and adjustable duty-cycle control.
A simple microcontroller can automate the system by monitoring temperature, humidity, sunlight intensity, and occupancy.

4. Scope of Work
Phase 1 — Research & Requirements
• Conduct a literature review on youth heat-stress hazards.
• Document environmental requirements (peak temperatures, humidity, solar irradiance).
• Define quantitative performance goals (e.g., ≥5°F temperature reduction).
• Establish safety, budget, and structural constraints.
Phase 2 — System Design
• Develop PV sizing calculations for peak load conditions.
• Design mounting structure, wiring, controls, and airflow pathways.
• Evaluate options for misters vs. evaporative cooling vs. high-flow fans.
• Produce preliminary CAD for the integrated dugout cooling system.
Phase 3 — Prototype Construction
• Build a full scale dugout prototype on a local baseball dugout.
• Assemble PV, cooling subsystem, sensors, controller, and water system.
• Ensure compliance with structural, electrical, and youth-safety guidelines.


Phase 4 — Testing & Evaluation
• Compare baseline vs. cooled dugout conditions using temperature, humidity, and WBGT measurements.
• Measure power generation, water use, run-time, and structural stability.
• Collect qualitative feedback from coaches/players (if allowable).
Phase 5 — Final Deliverables
• Design documents, schematics, 3D models, bill of materials, and test results.
• A complete Technical Data Package suitable for city parks, schools, or youth-league adoption.

5. Expected Impact
If successful, the system will:
• Reduce heat stress and improve safety for youth athletes.
• Enable communities to host games during warmer months without excessive risk.
• Demonstrate a scalable, clean-energy solution for public parks.
• Provide a real-world engineering application involving renewable energy, thermal management, and human-factors design.
