MEP Toolbook

MEP Toolbook provides native SI calculators for HVAC/MVAC, Electrical LV, Plumbing & Drainage, saved-calculation, export, and unit-conversion workflows. The app is designed for fast design-support checks by engineers, technicians, students, and reviewers. All current calculators, saved calculations, and exports are included in version 1. The calculator screens focus on inputs, units, final outputs, and short review notes. MEP Toolbook does not bundle standards PDFs, copied standards text, spreadsheet files, reference-book examples, or reference-book check figures. MEP Toolbook is a design-support calculator. Verify all outputs against project requirements, applicable codes, standards, manufacturer data, and professional engineering judgment.
