Abuja, Nijerya'daki çok aileli konutlarda bina zarfı malzemeleri ve yalıtımının enerji kullanımı, termal konfor ve maliyet üzerindeki etkisinin değerlendirilmesi

Global climate crisis has highlighted the pressing need for sustainable development, putting it at the centre of international discussion. The Paris Agreement serves as revolutionary international legal framework designed to power global efforts at combating climate change, setting global temperature targets increase to no more than 1.50C to 20 C less than pre-industrial levels. In order to keep up with this target, global emissions must be reduced by nearly 43% by 2030 and net-zero by 2050. Inarguably, two-third of total energy consumption and greenhouse gas emissions occur in building sector. Nigeria's energy demand far outweighs the supply with poorly designed buildings causing environmental degradation on one hand and economic hardship on the other, the nation's high reliance on non-renewable energy sources, frequent blackouts and rising demand for cooling provides opportunities for Alternative solutions. Net-zero Energy Buildings are one of the few ways to decarbonize an industry which is more energy-consuming than any other as they produce as much clean renewable energy as they demand annually. This research aims to create a simulation model that compares and analyses the energy performance of an Improved building envelope through material selection and insulation, to a conventional building envelope with respect to energy demand/consumption, thermal comfort and cost. by investigating the energy use pattern of buildings in Abuja and passive design strategies to reduce such energy use through envelope optimization. This study integrated qualitative and quantitative analytical approaches by comprehensive review of relevant literature and contextual data and the employment of a simulation-based approach using DesignBuilders EnergyPlus simulation engine to provide analysis on the energy performance two models. The Improved model show significant annual energy savings of up to 32.7%, average operative temperatures fell into acceptable ranges for thermal comfort, and annual CO₂ emissions decreased by as much as over 8 metric-tons.
