Dataset for: Lifecycle Carbon and Energy-Flow Assessment of Aerogel Glazing and Biogenic Insulation Pathways for Building Envelope Decarbonization Across Climate Zones

DescriptionThis dataset provides the core numerical results and lifecycle inventory (LCI) parameters for a parametric lifecycle assessment (LCA) and energy-flow analysis of aerogel glazing systems (AGS) and biogenic insulation materials. The study evaluates the carbon reduction potential of these advanced envelope components across six distinct climate zones (temperate, cold, subtropical, arid, tropical, and polar)
Key Data Components:
Lifecycle Carbon Profiles: A stage-by-stage breakdown (A1–C4) of cradle-to-grave emissions for double-glazed (DGS), triple-glazed (TGS), and commercial aerogel glazing systems (CAGS).Multi-Climate Operational Data: Annual heating/cooling loads and operational carbon intensities based on Typical Meteorological Year (TMY) climate files for cities including Shanghai, Anchorage, Singapore, Phoenix, and Paris.Fabrication Pathway Analysis: A comparative evaluation of embodied carbon for five aerogel production routes, ranging from commercial-scale supercritical drying to lab-scale synthesis.Material Benchmarking: Comparative carbon and thermal data for fiberglass, cellulose, foam board (XPS/EPS), and aerogel insulation at equivalent thermal resistance ($R = 3.0\text{ m}^2\text{K/W}$).Methodology: The assessment strictly conforms to ISO 14040 and ISO 14044 standards. Operational carbon was modeled using a validated MATLAB R2023a dynamic simulation scheme. Embodied carbon data were derived from the Inventory of Carbon and Energy (ICE) v3.0 database and peer-reviewed Environmental Product Declarations (EPDs)
Research Findings: The data confirms that the aerogel fabrication route is the primary determinant of lifecycle viability. Commercial AGS can achieve a net carbon reduction of up to $-142.5\text{ kg CO}_2\text{/m}^2$ over a 25-year service life in temperate climates, compared to $+608.0\text{ kg CO}_2\text{/m}^2$ for standard double-glazing.
