| dc.description.abstract | In addressing the critical issue of global climate change and the necessity to reduce greenhouse gas emissions, this paper zeroes in on residential structures in the extremely cold plateau agricultural and pastoral areas. It delves into strategies, methodologies, and frameworks aimed at realizing zero carbon objectives. This research analyzes the unique climatic resources—characterized by low temperatures and high levels of solar radiation—of these areas, and evaluates architectural components that are critical for zero-carbon designs in such specialized residential settings. Moreover, it critiques the constraints of conventional methods utilized in abstracting architectural prototypes based on building forms. These traditional approaches are often insufficient in offering objective, quantitative insights for particular functional spatial layout patterns. To overcome these limitations, this work introduces a quantitative method employing artificial intelligence for tagging information and computer vision for recognizing images. This approach enables the extraction of architectural spatial layout archetypes that capture the essence of usage patterns and climate responsiveness of dwellings in these extremely cold plateau agricultural and pastoral areas. Utilizing these archetypes, the paper proceeds to perform sensitivity analysis on individual elements and engages in multi-faceted optimization studies concerning the design parameters of architectural spaces and the combinations of enclosure structure design parameters prevalent in residential structures of these high-altitude, cold areas. Findings indicate that rammed earth constructions excel in overall low carbon performance, stone constructions exhibit moderate low carbon efficiency, while prefabricated concrete structures lag behind. By conducting a comparative analysis of the distribution of various design parameters (spatial design parameters and enclosure structure design parameters) in the optimized strategy collection, this study outlines specific sets of strategies for zero or low carbon building designs. These findings offer concrete design insights and methodologies for local architects aiming to achieve low carbon emissions in the design stage.
The introduction section of the paper sets the background by highlighting the background and the importance of the research, acknowledging the demand and the hurdles in developing zero-carbon buildings, particularly under the challenging conditions of extremely cold plateau agricultural and pastoral areas. It also surveys the current state of zero-carbon building research and practice both domestically and internationally, and outlines the scope, objectives, and strategy of this study.
Chapter Two focuses on the analysis of climatic resources in the extremely cold plateau agricultural and pastoral areas, alongside the relevant elements of zero-carbon building design models. This includes a detailed analysis of the area's unique climate features and identifying the key factors that affect the design of zero-carbon buildings, including the direction buildings face, the ratio of windows to walls, and the height of the building floors.
Chapter Three proposes strategies for enhancing the spatial layout patterns of residential structures in the extremely cold plateau agricultural and pastoral areas. The study first analyzes existing residential building spatial layout prototypes, followed by the introduction of several strategies aimed at boosting the quality of the indoor thermal environment and energy efficiency, all the while being mindful of the extreme climatic conditions.
Chapter Four conducts in-depth studies on single elements of residential buildings extremely cold plateau agricultural and pastoral areas, examining how various design elements relate to the overall carbon emission of the buildings throughout their lifecycle. This chapter details the exploration of optimal technological approaches, the calculation of carbon emissions during different phases of a building's existence, the selection of the best optimization methods, and the formulation of strategic optimization content. Moreover, it analyzes the sensitivity of variables, the adjustment of optimization algorithm parameters, and the analysis of combined strategic optimization objectives, offering solutions for the design parameters for three types of construction materials: rammed earth, stone, and cement.
Chapter Five, building on the typical architectural spatial layout patterns provided in Chapter Three, undertakes a multi-faceted optimization analysis of crucial architectural design elements highlighted in Chapter Four. The primary focus is on minimizing the carbon emission intensity throughout the entire lifecycle of the buildings. This chapter also assesses the carbon reduction potential of the three construction material types and delves into the specifics of the design parameters in the optimized solutions. | |
