Energy Signature Monitor (ESM). Development of a low-cost data acquisition system

The Energy Signature Monitor (ESM), an innovative energy monitoring system, addresses the data acquisition and analysis demands of test programmes which require monitoring of large samples of buildings. It has been developed aspart of the Whole Building Evaluation System (WBES). Only a nominal number of sensors are required per test site, with less stringent sensor accuracy demands as compared to laboratory investigations. The aim is to provide an inexpensive user friendly system for use by non-technical personnel.
