Preso Case Study

The Challenge Install an energy metering system that will allow individual tenants to be billed only for the energy they use. Because of the building's existing infrastructure, the system must drop in easily, with little or no downtime. Finally, the operation of this system must not add significant costs to building management. The Solution Preso's ThermoTrack
® Energy Flow Management System - a completely non-invasive meter that measures flow and temperature on supply and return water lines. ThermoTrack combines transit time ultrasonic technology with highly accurate industrial temperature sensors to provide precision energy measurement in BTUs, Watts, calories or tons. The non-invasive design is inexpensive to install, requiring no downtime, no rebuilding and no interference with the operation of the existing HVAC system. Simply strap on the flow and temperature industrial transducers and the system is ready to measure. With the ThermoTrack and a PC, up to 128 discrete energy zones Background Energy management is one of the most critical aspects of building maintenance and operations. Recently, one of the largest property management companies in North America contacted Preso with a special challenge: the tenants of a large telecommunications building were unhappy with the way they were being charged for energy use. Since energy bills were based only on square footage, customers using less energy to cool their offices and equipment were subsidizing the energy bills of customers using more. This discrepancy was not acceptable. may be monitored on a single three-wire RS485 digital communication network. With the addition of a simple software file used with Microsoft
® Excel, a single individual at one computer can administer a cost-effective energy station for an entire building. Software features include real-time energy rate and temperature sampling, totalization in selectable units and time frame, and meter status checking. Most importantly, with the ThermoTrack system, tenants may be billed only for the exact amount of energy that they use.
