About DC Design Tools
DC Design Tools is a small, growing set of free, browser-based utilities built for the people who plan and design data center infrastructure — layout drafters, cooling engineers, energy modelers, and anyone who'd rather get a fast, accurate first pass on a calculation or drawing than start from a blank CAD sheet or spreadsheet. Every tool here runs entirely in your browser: nothing you type is uploaded, stored, or seen by anyone but you, and there's no account to create.
Why browser-based, and why free
Data hall layouts, cooling equipment sizing, weather-file analysis, and adiabatic water calculations all involve the same handful of well-defined calculations and drafting conventions, over and over, project after project. A purpose-built browser tool can apply those conventions consistently and instantly — no CAD license, no macro-laden spreadsheet passed around a team, no waiting on desktop software to open. These tools are kept free because the goal is simply to be useful to the wider data center design community; more utilities (PUE/efficiency modeling, airflow estimation, UPS runtime sizing) are actively being built out.
What's available today
The Data Hall Layout Generator draws a scaled, exportable data hall floor plan — rack rows, hot/cold aisle containment, containment doors, perimeter clearance, and surrounding corridors and walls — and exports it as a real AutoCAD-compatible DXF or a vector PDF. The Cooling Equipment Calculator sizes FWU, CDU, and Chiller counts from an IT load and air/liquid cooling split, with configurable N/N+1/N+2/N+3/2N/2N+1 redundancy, and exports a formatted Excel report. The EPW Weather Converter parses EnergyPlus Weather files or fetches real Meteostat observations into charts, hourly tables, and a rolling-window filter for finding extreme periods. The Adiabatic Water Calculation Tool runs a full hourly psychrometric calculation across a year of weather data to estimate adiabatic pre-cooling water use, energy saved, and CO₂ avoided.
Frequently asked questions
Is DC Design Tools really free?
Yes — every tool on this site is free to use, with no account, subscription, or usage limit.
Do you store or see the data I enter?
No. All calculations, drawings, and exports happen locally in your own browser — nothing is transmitted to a server or stored anywhere outside your machine.
Can I rely on these tools for a real, stamped design?
These tools automate layout geometry and equipment-sizing arithmetic to give you a fast, consistent starting point — they don't replace review and sign-off by a qualified engineer, and any output should be checked against your project's own design standards before use in construction documents.
Can I suggest a new tool or report a bug?
Yes — use the Feedback button in the header on any page. Suggestions for new calculators or layout features are exactly what shapes what gets built next.
