As answered by people managing Gitql and LoadCairn.
LoadCairn's answer:
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.
LoadCairn's answer:
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.
LoadCairn's answer:
Critical facility engineers, data center technicians, facility managers, MEP consultants, data center project teams and students.
LoadCairn's answer:
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.
LoadCairn's answer:
A web app built on the Polsia platform. It installs on phone or laptop as a progressive web app (PWA) and works offline.
LoadCairn's answer:
Not available at this thime.
