Abstract:

A method of monitoring performance of a building system to control ambient conditions within the interior of a structure including: detecting a physiological condition of an individual within the interior of the structure; detecting an ambient condition within the interior of the structure; determining a user activity that is assigned to an area within the interior of the structure where the individual is located; and determining a wellness performance score of the area in response to at least the physiological condition, the ambient condition, and the user activity that is assigned to an area within the interior of the structure where the individual is located.

International Classification:

H05B 37/02

Abstract:

In exemplary embodiments of this invention, one or more I/O devices accept input from a human user. The input is indicative of a value for each control variable in a set of separate control variables. A computer analyzes the input and outputs control signals to specify a set of separate setpoints. Dimmers adjust the intensity or color of a set of luminaires according to the setpoints. The number of separate control variables is much less than the number of separate setpoints. Having a human control a small number of control variables, in order to control a much larger number of separate luminaire setpoints of luminaires, has at least two advantages: control is faster and control is more intuitive. In illustrative implementations, the luminaire setpoints that are being controlled are not functions of each other.
