Guests see a bright lobby and polite staff. Behind the technical doors lies another world — pumps, heat exchangers, and people with no room for error.This book is an engineer’s view of hotel operations: a living organism where hundreds of systems must run in sync around the clock, and comfort is never an accident, only invisible, constant work.Through nighttime emergencies and summer peak loads, it reveals the profession’s paradox: the better engineers do their job, the less anyone notices them.
