Questions & Answers

As answered by people managing LoadCairn and StackSource.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

LoadCairn's answer

Critical facility engineers, data center technicians, facility managers, MEP consultants, data center project teams and students.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?
