freecooling.org is an online feasibility analysis platform for Freecooling projects, aimed primarily at data centers, industrial facilities, and engineering consultants. It is based on TMYx 2011–2025 EPW hourly climate files, covers 168 weather station locations, and combines this with industrial electricity price data from more than 80 countries to estimate equivalent free cooling hours, annual savings, payback period, and cumulative returns over 20 years.
The platform offers a free quick preview where you can select a city and supply/return water temperatures to view indicative free cooling hours, annual savings, and payback period. After payment, the Economic Analyzer lets users edit engineering and economic parameters, compare single-loop and dual-loop systems, and view 1°C temperature bins, hybrid operating modes, full free cooling hours, cumulative savings curves, and year-by-year tables. It can also export client-ready PDF reports. The map module includes a global efficiency map, payback map, and electricity price map, making it useful for initial screening across multiple cities.
Pricing is straightforward: €79 for 1 city, or €129 for 2 cities. After purchase, you get 24-hour full access to the analyzer for the selected city or cities, including parameter editing and unlimited PDF exports within 24 hours. It is not a subscription; it is a one-time purchase by project/city. Note that the refund policy is relatively strict: because this is a digital product with immediate access after payment, refunds are generally not available once the analyzer has been accessed. Only technical issues such as complete inability to access the service can be raised within 24 hours.
The strengths are its clear positioning, low learning curve, and transparent methodology. The climate data, threshold calculations, equivalent free cooling hours, and economic model are all explained, making it suitable for producing early-stage client communication materials. The drawbacks are that the access window is only 24 hours, so it is not ideal for long-term iterative work; the results are positioned as feasibility screening and still require validation through on-site engineering design; and the main content does not disclose payment methods, the company’s jurisdiction, security and compliance details, team permissions, API availability, or system integration capabilities.
It is suitable for early-stage evaluation of cooling system retrofits, comparing data center energy-saving options, and helping engineering consultants quickly generate project reports. It is not a replacement for full HVAC design or an enterprise collaboration platform. The main content does not provide information about access from China, so real-world network and payment availability are unknown. If access is limited, alternatives include EnergyPlus, OpenStudio, IES VE, TRNSYS, or local engineering consultants building models based on Chinese weather and electricity price data.
