Abstract
Key words: Life cycle impact,Climate change,Building envelope,Environmental benefits Abstract： Climate change has been raised as one of the most important issues for human beings. In the current and future climate, which parameters will affect indoor comfort and building energy consumption? How to set the building envelope structure parameters? This work aims to analyze the impact of climate change on the renovation and energy consumption of typical existing buildings only in France or for certain climate types. Through the calculation of life cycle assessment, the effectiveness of the building envelope in the current and future climates is determined. It is guaranteed that the reconstructed and updated buildings can provide comfort and benefit the health of the occupants. The purpose of this research is to better balance and optimize the renovation and energy efficiency of existing old buildings in France in the context of climate change. Starting from the design of the main body and maintaining the structural parameters, based on the optimization of the building facade and the optimization of the shading system, model construction, simulation and data training are carried out. Provide a building life cycle assessment process based on BIM and PLEIADES so that the process can be executed in the concept phase, design phase and construction drawing phase of the design. This research attempts to find residential building forms and envelope structure types that can meet energy-saving and comfort requirements and cope with future climate changes, and provide a reference architecture design for the architect’s early implementation. In addition, we will explore the use of the best simulation in the operation phase through integrated comprehensive analog and LCA digital tools to achieve the goals of “health, comfort” and “energy saving and consumption reduction”.
