論文概要:This study focuses on the biomimetic approach to passive energy-saving design for rural residences in Northern Zhejiang, China. It addresses the challenges of high energy consumption and poor thermal insulation in rural buildings caused by nonstandard construction materials and methods. By integrating passive energy-saving technologies with local climate and resources, the research proposes a comprehensive design framework to improve thermal comfort and provide a reference model for rural construction. The key points of the study are summarized below:

1. Background and Purpose: The study highlights the high energy consumption of rural buildings in China and the challenges of improving energy efficiency. Unlike previous research that focused on single technologies, this study emphasizes an integrated approach, defining the "rural house with its yards" as a basic rural building unit (RBU). It uses biomimetic principles, prototype theory, and bioscience to develop a theoretical framework for combining passive energy-saving technologies with functional and material aspects during the early design stage.
2. Investigation and Analysis: An investigation into Northern Zhejiang’s geography, climate, resources, and economy identifies challenges in rural residences. Using simulation tools, the study evaluates passive energy-saving technologies suitable for the region, revealing issues such as poor insulation and suboptimal design. Case studies of two villages provide detailed insights into existing problems.
3. Theoretical Framework and New Approach: The study proposes a biomimetic concept that considers the RBU similar to a biological cell, with an internal structure that supports energy efficiency. The framework integrates prototype theory, bioscience, and passive energy-saving strategies to create a holistic approach for rural construction.
4. Development of the RBU Prototype: A functional prototype for rural residences is developed based on field data. The design includes adaptable plans that cater to various functional needs, with vertical and horizontal tunnel spaces incorporated for energy efficiency. The prototype allows flexibility in form and functionality.
5. Design Menu for Rural Residences: A "design menu" is created using topological principles, offering various options for rural houses by considering cavity spaces, composite exterior walls, and the impact of topography. This menu helps adapt the RBU prototype to different requirements.
6. Case Study 1: Integrated Optimization in Anji County: A typical house in Anji County undergoes thermal performance simulation and field measurements before and after renovation based on the proposed model. Results confirm significant improvements in thermal comfort, demonstrating the effectiveness of the approach.
7. Case Study 2: Tubular Houses in Deqing County: Another case study focuses on traditional tubular houses in Deqing County. Through field measurements, modeling, and energy simulations across winter and summer, the study evaluates the impact of different renovations. Results again show clear improvements in thermal comfort, validating the proposed model.

This study provides a robust framework for integrating passive energy-saving technologies into rural construction, offering practical solutions for energy efficiency and improved living conditions in rural China. The findings serve as a reference for similar contexts worldwide.
