System and method for building climate control

Abstract

A method of controlling the climate of a building includes determining a difference between a current aspect of a climate in a building and a set point for the aspect of climate in the building for one or more zones of the building, summing the differences at a climate system controller, and determining a set point for one or more operating variables of one or more components of a climate system in the building based on the sum of the differences. A climate system for a building is also disclosed.
