Frequently Asked Questions

Yes, 100% free with no signup, no account creation, and no paywalls. All calculators run entirely in your browser. This is an educational project built to help data center professionals make better planning decisions.

The calculators use industry benchmarks and publicly available data to provide AACE Class 4–5 estimates (conceptual/feasibility level, ±30–50% accuracy). They are designed for early-stage planning and comparison, not for procurement or final budgeting. Always validate with licensed engineers and local contractors.

The tools reference ASHRAE TC 9.9 thermal guidelines, TIA-942-B data center infrastructure standard, EN 50600, NFPA 75/76 fire protection, ISO 27001 information security, ISO 50001 energy management, Uptime Institute Tier standards, and GHG Protocol for carbon accounting.

Yes. Most calculators include a print-optimized export function that generates a clean PDF layout. Use the export or print button within each tool to generate a report suitable for sharing with stakeholders.
