Carbon-Neutral Design Strategies for Net-Zero Energy Buildings: A Comparative Study of Different Design Approaches in Eti-Osa Local Government Area, Lagos, Nigeria

Several cities have set carbon neutrality targets. This paper aims to assess various approaches for a progressive city to achieve carbon neutrality in building design, construction and occupancy. The study explores various carbon-neutral design strategies and its effectiveness applicable to net-zero energy buildings. Provide recommendations for implementing sustainable design practices in Lagos, Nigeria. The research outlines the carbon neutrality design strategies using credible sources, concepts and existing case studies. The findings reveal that most carbon neutrality strategies are achievable and that its widespread adoption in Lagos will enhance its sustainability target. The incorporation of passive design strategies, including natural ventilation, shading devices, and insulation, with active systems, such as energy-efficient lighting and HVAC systems. Notably, there are a few incentives for the adoption of smart systems by some financial institutions and this a step towards better implementation of carbon neutral design strategies. Implementing such with governmental incentives would substantially enhance control over its carbon neutrality efforts. Consequently, it is suggested that cities striving for carbon neutrality should consciously encourage and advance the passive and active design strategies in achieving carbon- neutral buildings in Nigeria, irrespective of design constraints, as a fundamental strategy for achieving their goals.
