論文概要:This research investigates strategies to enhance the winter indoor environment of rural houses in Qingdao, China, through innovative applications of straw-filled bricks and sunrooms. Utilizing field surveys, experimental analyses, and numerical simulations, the study identifies significant challenges in the thermal performance, energy efficiency, and air quality of traditional coastal rural houses.

Key findings include the effectiveness of straw-filled hollow bricks as an environmentally sustainable solution to improve building envelope insulation. Comparative studies of various straw materials demonstrate notable reductions in heat transfer and energy loss. Additionally, the study explores the incorporation of sunrooms to utilize passive solar energy, providing cost-effective design strategies that enhance thermal comfort while minimizing heating energy consumption.

Through simulations using EnergyPlus software, the research evaluates the thermal and energy-saving impacts of envelope renovations and sunroom designs. Results highlight the potential for reduced heating loads, improved indoor temperatures, and better air quality. This study contributes to sustainable rural development by proposing actionable solutions to address the energy and environmental challenges of rural housing in cold coastal regions.

Keywords: rural housing, winter environment, straw-filled bricks, sunrooms, energy efficiency, thermal comfort.
