THIS SPREAD SHEET CAN BE USE TO CALCULATE THE HEAT LOAD IN BTU FOR SPECIFIC ROOMFull description
The primary objective of this report is to provide a convenient, consistent and accurate method of calculating heating and cooling loads and to enable the designer to select systems that meet the requirement for efficient utilization and are also res
