This page is designed to help you find out whether LoadCairn is good and if it is the right choice for you.
LoadCairn is a set of free planning and sizing calculators for data centers and critical facilities. Every calculator shows its formula and assumptions, so engineers can check the math instead of trusting a black box.
Calculators include: - UPS runtime - Cooling load - Airflow / CFM - Rack power - Generator sizing - PUE - Dew point and humidity - kW / kVA / amps
LoadCairn is a planning and sizing tool. It complements SCADA, EPMS and BMS systems rather than replacing them, and it is not a monitoring system.
Built for critical facility engineers, facility managers, MEP consultants and data center project teams who need quick, transparent estimates during design, upgrades and capacity planning.

Every calculator shows its formula, inputs and assumptions, with references to ASHRAE and NIST. Engineers can check the math instead of trusting a vendor tool that hides it.
Vendor calculators from APC, Eaton and Vertiv are tied to their own products and don't show their work. LoadCairn is vendor-neutral, free with no account, and covers power, cooling and facility metrics in one place. It also works offline in data halls with no signal.
Critical facility engineers, data center technicians, facility managers, MEP consultants, data center project teams and students.
I've worked in data centers for 20 years. Most sizing still happens in old spreadsheets or vendor tools that won't show the math. I built LoadCairn so engineers have quick, transparent estimates they can defend in a design review.
A web app built on the Polsia platform. It installs on phone or laptop as a progressive web app (PWA) and works offline.
