TELBECC - A Computational Method and Computer Program for Analyzing Telephone Building Energy Consumption and Control

TELBECC--A Computational Method and Computer Program for Analyzing Telephone Building Energy Consumption and Control By P. B. GRIMADO* (Manuscript received February 2, 1983) Telephone Building Energy Consumption and Control (TELBECC) program has been developed to accurately and efficiently analyze environmental control and energy use in telephone company buildings. The program simulates various operational plans to determine the relative energy and cost savings. By analyzing the operation of the heating, ventilation, and air conditioning system as it regulates a changing environment, TELBECC calculates the heating and cooling load, dry-bulb temperature, and relative humidity in the building. The user specifies the building's dry-bulb temperature limits, which are the control variables for the program analysis. The simplified computat i o n a l p r o c e d u r e of t h e p r o g r a m i n c o r p o r a t e s a recursive s c h e m e using t i m e series to perform the necessary calculations. The results of the computations can be obtained for different periods: the quarter hour, hour, day, or month. Energy consumption and control in several equipment buildings located in three different geographical areas have been analyzed by TELBECC. Analysis and comparison of the resulting data demonstrate the advantages of the program. I. INTRODUCTION An ambitious energy-cost savings program has been instituted to reduce energy use in telephone company buildings. In recent years, telephone companies have saved energy mainly by redesigning and * Bell Laboratories.
