Abstract:Digital design technology is crucial for building energy efficiency design

while the key of building energy efficiency design is to analyze the entire design process

dynamic balance and energy cost. Through the application of digital technology in architectural design during its earlier phases

we can analyze such factors as local climate and terrain

create a "virtual building"

simulate its actual condition

and conduct a scientific quantitative analysis of the key problems in architectural design. These actions will optimize the proposed design in a timely manner and achieve energy efficient design under the guidance of scientific analysis. Meanwhile

by exploring energy efficiency design procedure based on digital technology

we can adapt to a higher standard of energy efficient design in our new times.
