論文概要:
Building energy efficiency design can effectively reduce heating energy consumption and improve indoor environmental problems in rural areas, which plays a crucial role in alleviating the increasingly severe environmental and energy problems. In this study, typical traditional dwellings in Northeast Sichuan, China are taken as the research object. It proposed the strategies for energy-saving and environmental improvement of dwellings, particularly addressing the issues of high humidity in summer and inadequate heating in winter. In addition, it explores the use of low-cost, low-tech solar room of traditional dwellings models. The conclusions of this study are as follows:
In Chapter 1, the study introduces the current status, challenges, and opportunities of rural dwelling in Northeast Sichuan, China. And it proposes the aims, significance, and framework of the research.
In Chapter 2, the study reviews various approaches to energy-saving design, the latest technological advancements, and saving energy strategies of rural dwellings all over the world. In Chapter 3, It introduces the methodology of in-site surveys, experiments and the evaluation of simulation experiments include temperature and PMV.
In Chapter 4, we analyze the indoor thermal environment in summer in northeast Sichuan, including the influence degree of traditional architectural features, indoor thermal environment parameters, and how to optimize them without compromising traditional aesthetics.
In Chapter 5, we detail the assessment of current heating methods and their effectiveness, explores both the energy consumption patterns and the impact on indoor air quality, evaluates potential solutions for improving heating efficiency while maintaining the integrity of traditional designs.
In Chapter 6, it proposes comprehensive strategies to optimizing the thermal performance of traditional dwellings from walls, roofs, and windows. We analyze four different cases simulated for each envelope considering both cost-effectiveness and compatibility with traditional construction modes.
In Chapter 7, The chapter assesses the feasibility, benefits, and potential challenges of implementing solar energy solutions in rural Northeast Sichuan, aiming to provide a sustainable alternative to traditional heating and cooling methods.
In Chapter 8, a comprehensive summary and reflection on the findings from all the previous chapters are provided. This final chapter also presents the broader implications of the research, discusses its limitations, and proposes prospects for further studies in this field.
