A mathematical model,method theory and calculation steps are given. Error analysis results show that this method can be applied accurately to practical engineering projects. In a case study of energy-saving quantity assessment before and after retrofitting on a certain hospital in Shanghai,with energy simulation software TRNSYS,detailed application of this method is introduced and analyzed. The method is applied to the case of energy-saving quantity assessment to a hospital in Shanghai before and after retrofitting with the energy simulation software TRNSYS.展开更多

The essence of green building is to build a healthy and general environmentally friendly living environment under the premise of reducing the consumption of resources and improving the efficiency of resource utilization in the whole life cycle of construction activities. Green building bearing function is further diversified, integrated, and has a self-initiative. The development of the green building, local isolated from the original single building greening, greening, landscaping site platform, gradually developed for construction area and the surrounding green ecological system of comprehensive, three-dimensional stratified construction and network connection. Its model gradually shows the micro area of the construction of the ecological system and architectural space integration. This paper integrates the passive integrated energysaving technology to construct the novel construction paradigm.展开更多
