Energy Use in Office Buildings: Analysis of Office Building Energy Use in a Random Sample of 1100 Buildings

摘要

The collection and analysis of an energy use data base obtained from a sample of approximately 1100 randomly selected major office buildings located in 20 US cities are reported. Chapter 1 presents information on the collection of the data and on the characteristics of the buildings for which data were gathered. In Chapter 2 a tabular analysis of the energy consumption data is performed by census division, fuel type, building age, height, downtown/suburban location, and class of space. Chapter 3 compares the data base - denoted as the 20 City Data Base - with the data base obtained from the Experience Exchange Report denoted as the EER Office Building Sample. Both data bases were for the year 1977. Table 3-1 presents the comparison of the two data bases. In general the EER Office Building Sample buildings used more energy than did the buildings in the 20 City Data Base: i.e., the buildings in the Experience Exchange Report are biased towards higher energy use buildings. Furthermore, the EER Office Building Sample has proportionally more gas and steam buildings than does the random sample. On a national basis the EER Office Building Sample buildings used approximately 10% more energy than did the buildings in the 20-City Data Base in 1977. (ERA citation 07:014768)
