Testing Data Acquisition Systems for Use in Monitoring Building Energy Conservation Systems
MetadataShow full item record
Dedicated microprocessor-based data acquisition systems are beginning to be used to monitor the energy savings from building energy conservation retrofits. These systems capture data from important monitoring points and store the values for periodic transfer to a central location. While there are many data loggers available that appear suited to this task, choosing between them is complicated by a large number of manufacturers, a lack of standard communications protocols, and most significantly, no standardized tests for reporting their capabilities. This paper addresses the last point with a battery of tests that were developed and applied to data loggers from nine manufacturers.
