EVALUATION OF NET ZERO ENERGY PRINCIPLES FOR THE DESIGN OF DE-CLAY BOUTIQUE HOTEL IN LAGOS, NIGERIA

Abstract

The dissertation titled “Application of Net Zero Energy Building Principles in the design of a boutique hotel in Lagos, Nigeria” intends to investigate the application of net zero energy building principles, in the hospitality sector in Lagos, Nigeria. With buildings contributing over 30% to global energy consumption and the hospitality sector’s rising energy demands, this study aims to provide a sustainable architectural response by integrating NZEB strategies into a context-sensitive hotel design. A mixed-methods approach was employed, combining case studies of local and international boutique hotels, expert interviews, structured questionnaires, and an extensive review of passive and active energy systems. Findings reveal that passive design strategies such as building orientation, natural ventilation, and daylight optimization can significantly reduce operational energy loads when tailored to local climatic conditions. Additionally, active systems like solar photovoltaic arrays, energy-efficient lighting and HVAC systems, smart systems, and water-saving technologies further enhance these. The design proposal for a boutique hotel in Eko Atlantic City applies these principles holistically, demonstrating the feasibility of achieving net-zero without compromising luxury, guest comfort, or aesthetic value. The study identifies key barriers to NZEB adoption in Nigeria, including high initial investment costs, limited technical expertise, and weak policy enforcement. It affirms that with the right blend of policy support, design innovation, and stakeholder engagement, NZEB-driven architecture can redefine energy resilience and environmental responsibility in the Nigerian hospitality sector. This research contributes to bridging the knowledge gap in sustainable hotel design in West Africa. It provides a replicable model for integrating net-zero energy strategies into commercial buildings in developing economies.
