چکیده
Abstract Buildings account for 36% of global final energy demand and are key to mitigating climate change. Assessing the evolution building stock its is critical support mitigation strategies. However, most studies lack granularity overlook heterogeneity in sector, limiting evaluation transformation scenarios. We develop residential scenarios along shared socio-economic pathways (SSPs) 1–3 assess stock, demand, CO 2 emissions space heating cooling with MESSAGEix-Buildings, a modelling framework soft-linked an integrated assessment framework. MESSAGEix-Buildings combines bottom-up turnover, discrete choice efficiency decisions, accounts geographical contexts, socio-economics, buildings characteristics. Global projected decrease between 34.4 (SSP3) 52.5% (SSP1) by 2050 under improvements electrification. Space starkly rises developing countries, increasing globally 58.2 85.2% 2050. Scenarios substantially differ uptake efficient new construction renovations, generally higher single-family homes, patterns across income levels locations, south driven medium- high-income urban households. This study contributes advancement sector knowledge be assessed integration other sources context change sustainable development.

This study presents a dynamical systems model for long-term scenarios of demand in the aviation sector and resultant emissions of CO2 and NOx. We analyze the dynamics of demand growth for aviation, particularly in the emerging markets of developing nations. A model for subsonic aviation emissions is presented that reflects the consequences of industry forecasts for improvement in aviation fuel ...
متن کاملEffects of Southern Wall Angle on Heating Performance and Energy Consumption of Residential Buildings in Yazd
The southern wall plays an important role on heating perfrmance and energy consumption of residential buildings. This study investigates the effects of southern wall angle, glass area and external canopy on heating perfrmance and energy consumption of a typical residential building in Yazd. Using causality method and thermal simulation by DesignBuilder simulator, we examined energy consumption ...
