Multi-Objective Optimization for Winter Heating Retrofit in Rural Houses of Cold Regions: A Case Study in the Wusu Area

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(9), P. 3760 - 3760

Published: April 28, 2024

In regions of China experiencing severe cold, the duration winter heating season significantly contributes to elevated energy consumption in rural dwellings. This study focuses on typical brick-and-concrete homes Wusu area. Utilizing Rhino–Grasshopper parametric modeling platform, it aims minimize heating-related carbon emissions and overall costs associated with retrofitting. The approach involves improving insulation properties building envelope reduce requirements. Additionally, incorporates solar photovoltaic systems atop homes, upon low-carbon, passive, energy-efficient design principles. By examining influence various factors housing consumption, research employs entropy weight method identify most effective solutions. goal is explore strategies for retrofitting dwellings areas faced harsh conditions, aligning objectives preferences Applied Sciences. simulation results reveal following: (1). comparison baseline scenario, 42.2% optimized solutions within Pareto frontier satisfy current standards 75% savings residential design. (2). lowest recorded thermal index buildings can reach 12.427 W/m2, at which point rate 79.5%. (3). Within identified by frontier, 80% exhibit initial investments that are lower than cost over lifecycle due reduced (dCg < 0), demonstrating economic feasibility proposed strategies.
