How to Use This Calculator
Enter your gym's physical and operational profile
Start with floor area and HVAC type — these two inputs drive the largest share of a gym's energy consumption. HVAC alone typically accounts for 40-50% of total electricity use. High-efficiency systems and mini-splits can cut that in half compared to aging rooftop units. Enter the number of powered pieces of equipment: treadmills, ellipticals, bikes, cable machines, TVs, and saunas all add up.
Set operating hours and check the pool toggle
A 24-hour gym uses 50% more energy than a 16-hour operation simply because HVAC and lighting run constantly. If your facility has an indoor pool, toggle it on — pool heating, filtration, and dehumidification typically add 40-60% to total load and represent the single biggest opportunity for solar offset.
Read the commercial solar results
The calculator shows gross system cost, ITC 30% federal credit, MACRS 5-year accelerated depreciation benefit, demand charge reduction, simple payback, and 25-year savings. Commercial gyms benefit from MACRS depreciation that residential solar doesn't get — it effectively adds 10-12% to the financial return in the first five years.
The Formula
The demand charge reduction is critical for commercial solar ROI. Many utilities charge large commercial accounts $10-20 per kW of peak monthly demand — often 20-40% of the total bill. Solar production during peak afternoon hours (when gyms are busiest) directly reduces the billed demand, compounding savings beyond simple kWh offset.
Example
Metro Athletic Club — Dallas, TX (10,000 sq ft with pool)
A mid-size Dallas gym with 800 members, standard commercial HVAC, 80 equipment units, an indoor lap pool, and 16-hour daily operation. Electricity rate $0.12/kWh.
Result
Commercial solar ROI is faster than residential due to MACRS depreciation and demand charge reduction. This gym recovers its net investment in under 6 years, then saves over $60,000 per year for the remaining 20+ years of panel life.
