Pros And Cons Of Residential Building Energy Consumption Models

In order to estimate the energy consumption demand of residential buildings, the status and shortcomings of current energy consumption models is important. Then it proposes and develops a residential building energy consumption demand model based on a back propagation neural network model.. In addition, the different models corresponding to different buildings can take into account the potential energy structure adjustments and relevant energy policies. Treating the residential building energy consumption as a relatively independent statistical object is good for systematically accumulating the underlying data for residential building energy consumption and understanding the basic conditions of residential building energy consumption. It …show more content…

However, electricity prices declined in real terms during this period and, as a result, expenditures for electricity did not rise as quickly as overall usage. Still, electricity expenditures rose with 0 increased demand from $144 billion in 1980 to $238 billion in 2005 as measured in constant 2005 dollars. Use of natural gas, the second largest energy source in the buildings sector, was essentially at from 1980 to 2005 and decreased as a percentage of total use from 28 percent in 1980 to just 20 percent by 2005. Still, expenditures rose significant due to an increase of more than 60 percent in the price of natural gas, which was driven largely by increased utility demand for gas to be used for electricity production. This large increase in turn drove the need for more power plants and for more coal, uranium, and natural gas to generate electricity. Despite a 14% increase in total buildings and a 22% increase in total floorspace since 2003, energy use in the estimated 5.6 million U.S. commercial buildings was up just 7% during the same period, according to new analysis from the 2012 Commercial Buildings Energy Consumption Survey …show more content…

Results from the building interviews released about a year ago were combined with energy consumption data provided by building respondents or their energy suppliers and NOAA weather data to model how energy is consumed within buildings. Through CBECS and these modeling efforts, EIA is able to provide the only comprehensive source of detailed information on energy use in the wide variety of commercial buildings across the United States. . Total electricity consumption in commercial buildings has almost doubled since CBECS began tracking it. Electricity consumption increased from slightly more than 2,200 trillion Btu in 1979 to 4,241 trillion Btu in 2012; this change is statistically significant. Total natural gas consumption decreased between 1979 and 1986 but then remained close to its 1979 level through 2012. The change in total natural gas consumption from 1979 to 2012 is not statistically
