| Based on the rethinking of architecture design and energy-saving design,the paper integrates the two from the angle of optimization design,and studies the energy-saving optimization design of university dining buildings in cold regions.The purpose of the paper is to reduce the energy consumption of university dining buildings and provide method for designers in the process of university dining buildings’ rebuilding or renovation.The energy-saving optimization design is to increase the components of architecture design’s rational thinking,and also provide data support for energy-saving design.It will provide a new logical method to make the building not only meet the basic functional requirements and spiritual and aesthetic requirements,but also achieve the purpose of saving energy,thereby building a more scientific concept of architecture.The idea of the energy-saving optimization design in this paper is "Element-form-energy consumption".Among them,"element" is the object of optimization design,which includes wall,roof,window,floor of the "elements of architecture",and the single space’s quantity,shape,quality and the multi-space’s combination relationship of the "elements of composition";“Form” is the result of the optimization design,the optimization design for the elements will ultimately transform into the change of the architecture form,and the change of the architecture form is based on the building energy consumption;"Energy consumption" is the basis study of the article,through the concept introduction of energy-saving contribution rate,and based on the site research and drawing arrangement of a large number of university dining buildings in the cold regions and the energy consumption simulation correction,the standard model and standard simulation method are obtained,and the mathematical model energy-saving contribution rate will be utilized to guide the architecture energy-saving optimization design.According to this optimization design idea,the paper finally obtain suitable methods for university dining buildings’ optimization design through “field investigation – drawing arrangement – simulation verification-optimization design – design verification”. |
