Description

technical field [0001] The invention belongs to the field of building energy consumption prediction, in particular to a MapReduce-based BP neural network building energy consumption prediction method. Background technique [0002] With the continuous acceleration of the urbanization process, the energy problem has become increasingly prominent. Building energy conservation has become a research hotspot in today's social development. A comprehensive evaluation and comprehensive analysis of building system energy consumption is the premise and basis for energy-saving renovation or energy-saving design. The establishment of a prediction model that reflects changes in energy consumption is an effective way and an important means to analyze and understand the changes and development characteristics of building energy consumption on a macro scale to provide decision-making basis for energy conservation in public buildings. [0003] BP neural network prediction has a strong nonline...
