I Love MEP: Free Mechanical, Electrical, and Plumbing tools

What is I Love MEP?

I Love MEP is a free online collection of browser-based MEP calculators and engineering planning tools for mechanical, electrical, plumbing, HVAC, fire fighting, fire alarm, ELV, pumps, tanks, cables, lighting, drainage, standards, examples, and PDF calculation reports. Engineers, contractors, estimators, consultants, students, and facility teams use the site for fast planning-level checks before detailed design verification. The tools are built around practical project inputs, sample data, warnings, methodology notes, related calculators, and downloadable reports instead of forcing users into logins or spreadsheets. I Love MEP is intended for early design, tender review, BOQ sanity checks, site coordination, and technical discussions. Calculator outputs are not final authority approvals or stamped engineering designs. Results should be checked against project specifications, local codes, standards, manufacturer data, and qualified engineering review before procurement, construction, or submission.
