Ashrae Journal - October 2008 - (Page 20) the previous contest would be the ability to predict the performance of specific energy end uses. Contest to develop the most interesting, informative user interface for presenting monitored data from the living lab. Members would compete to design innovative user interfaces for video displays of energy use and building performance. These displays ultimately would be implemented in the control software for the headquarters building. Winning interfaces would provide a higher degree of clarity and communication to users than interfaces currently available. Emphasis would be placed on clarity and the educational value of the interface that could be licensed to private sector vendors. Contest by joint student branch and ASHRAE chapter to predict energy use in the headquarters building using model- Figure 1: Data acquisition, storage and remote access architecture for the living lab. ing software. Members of local ASHRAE Chapters would team with student branch members to develop performance of the DOAS without preconditioning vs. the DOAS building simulation models that can be used to predict energy data acquisition, storage remote access architecture for the living use in the headquarters building. This would serve as a training lab. preconditioning in conjunction with the mechanical heating opportunity for the student members and cooling systems under real-world and a mentoring opportunity for building operations.
