User Location-Specific Data for Smarter Smart Grids
Abstract
This project focused on modifying and evaluating the Readings at Desk (RAD) controller, a lighting control system developed and patented by Erik Page & Associates, Inc. (EP&A) that: 1) Measures the amount of light present in the workstation; 2) Allows occupants to define desired light levels at the workstation; 3) Communicates to wirelessly-controllable overhead lighting systems. In measuring conditions at the desk, the RAD controller differs from typical lighting control systems that rely on daylight sensors located at the ceiling. There are inherent advantages associated with using sensors that are located at the occupant’s workstation in that they more accurately represent what the occupant is experiencing, theoretically providing a much better closed-loop control point. The technical objectives of this Phase I project were: 1) Objective 1: Modify the RAD controller such that it can report energy use of connected devices and receive status updates and/or commands from external sources, such as grid or demand response signals. 2) Objective 2: Modify the RAD controller to measure the temperature at a workstation, accept temperature preferences from users, and communicate controls information to a building’s HVAC systems. 3) Objective 3: Carry out a comprehensive performance test of the modified RAD controller in controlling lighting and HVAC systems. All three technical objectives were met in the Phase I project execution, as well as an additional “bonus” technical achievement not described in the original proposal: the development of a computer monitor-mounted occupancy and lighting sensor board.
