A Research On The Interactive Mechanism And Method Of Building Scheme And Performance Optimization Based On Energy Consumption Simulation

As one of the main energy-consuming industries,the construction industry is responsible for energy conservation and emission reduction.With the use of energy simulation tools in the design of energy-saving buildings,the energy consumption during the building operation phase can be simulated in advance,and the energy-saving effect of the constructed building can also be pre-evaluated to assist the continuous optimization of the building scheme and its environmental performance.However,limited by the current working mode of design institutes and the characteristics of energy consumption simulation work,the interaction between energy consumption simulation and design optimization is generally carried out in the design development stage and led by professional simulation staff.The optimization of building performance is limited and the cost is relatively high.This study mainly focuses on how to carry out the energy simulation and scheme optimization by the person in charge of the early design stage,the architect.The interactive relationship between "building scheme" and "performance optimization" is re-examined to provide relevant practitioners with new energy-saving building design processes and scheme optimization ideas.Firstly,through the relevant literature reviews,it is concluded that the main difficulties of the current interactive research on scheme design and performance optimization are:the incomplete understanding of the characteristics of early design stage,the non-benchmarked trade-off between the expression of the design idea and the objective simulation calculation results,and the mismatch between the common energy consumption simulation tools and the modeling tools,etc.In Chapter 2,based on the essence of architectural design and performance optimization,their interactive relationship in traditional design mode and integrated design mode are respectively discussed.The existing tools supporting this interaction are also summarized and classified.In Chapter 3,the characteristics of performance optimization during the early design stage is summarized,and then an architect-led interactive mechanism for early scheme design and performance optimization is constructed with the lessons drawn from the interaction theory and mechanism design concept.The interactive subjects,interactive medium and influencing factors of interactive effect are also clarified.In Chapter 4,a specific "design-simulation-feedback-optimization" interactive process is designed based on the interactive mechanism,and appropriate design modeling software(Trimble SketchUp)and energy consumption simulation plug-in(OpenStudio)are selected for the subsequent interactive tool development.Chapter 5 focuses on the model conversion efficiency problem during the interactive process.It is pointed out that the research gap lies in how to convert the SketchUp building design model with three-dimensional components into a thermal perspective geometric model for the following energy simulation.In Chapter 6,a plug-in used for automatic extraction and conversion of SketchUp model geometry information was written by Ruby.In Chapter 7,an actual design case is selected,based on which the interactive process is conducted,in order to verify the practicability of the new conversion plug-in,as well as the feasibility and effect of the entire interactive process.The main results of this research are:(1)an architect-led interactive mechanism for early scheme design and performance optimization;(2)the interactive process based on the interactive mechanism and the ideal application steps of the corresponding interactive tool;(3)a new plug-in for automatically extracting and converting model geometry information from the SketchUp design model to assist OpenStudio energy model modeling;(4)the validity verification of the above interactive process and conversion plug-in through an actual design case.
