Core Viewpoint - The promotion of energy conservation and carbon reduction in rural buildings is crucial for achieving China's carbon peak and carbon neutrality goals, with significant potential for energy savings in rural residential buildings [1][6]. Group 1: Energy Consumption and Emissions - In 2022, energy consumption from building operations reached 1.19 billion tons of standard coal, accounting for 22% of national energy consumption, while carbon emissions were 2.31 billion tons of CO₂, representing 21.7% of national energy-related carbon emissions [1]. - Rural residential buildings contribute to 21% of the total energy consumption and carbon emissions from buildings, highlighting the need for targeted energy-saving measures in this sector [6]. Group 2: Importance of Low-Energy Buildings - The "Accelerating Energy Conservation and Carbon Reduction Work Plan for the Building Sector" aims for an increase of over 20 million square meters in new ultra-low energy and near-zero energy buildings by 2025 compared to 2023 [3]. - Ultra-low energy buildings are defined as having energy consumption levels reduced by over 50% compared to existing standards, while near-zero energy buildings achieve reductions of 60% to 75% [4]. Group 3: Challenges and Opportunities in Rural Areas - The transition to ultra-low energy and near-zero energy rural homes is essential for promoting green development and enhancing the low-carbon level of rural buildings [6]. - Key challenges include poor thermal performance of building envelopes, low efficiency of energy systems, and insufficient utilization of renewable energy in rural areas [7]. Group 4: Technological and Industrial Development - The development of high-performance building envelopes, photovoltaic systems, and energy-efficient technologies is expected to drive the growth of the building energy conservation industry [7]. - Promoting green building materials in rural areas can support the construction of modern, energy-efficient homes and accelerate the high-quality development of the green building materials industry [7]. Group 5: Policy and Financial Support - Strengthening policy guidance and financial support is necessary to facilitate the construction of green low-carbon rural homes, including subsidies and low-interest loans [11][12]. - Establishing a legal framework and third-party certification systems for ultra-low energy and near-zero energy buildings is crucial for ensuring consistent standards and promoting widespread adoption [9][10].
