Abstract

The population of Lagos is on regular increase which is estimated to cross 30 million marks by 2030 according to
National population commission statistics. This would increase the demand for built environment meeting
sustainable Development goal 11 (Sustainable cities) in line with International Union of Architects (Uia) 2050 vision to
actualize Architectural projects that are Carbon-free and low energy thus leading to the choice of the Research
topic A sustainable mixed-use vertical with emphasis on minimising carbon emission and energy efficiency as a
means to having a built environment that contribute positively to climate change. This would be achieved by
adopting design strategies, use of energy efficient technologies and Hybrid renewable energy sources which
comprises of Hydro water generation using water body close to the site, solar energy generation and biofuel
sourced from biodigester installed in the septic tank. The Hybrid energy generation is expected to contribute to not
less than 70% of the energy need of the facility in addition to other design means, energy efficient technologies that
will enable the project to be low energy thereby emitting less carbon dioxide. The literature review further discussed
notable scholarly articles, publications, journals, Architectural research on the research topic revealing information
on strategies to low energy and minimising carbon emission in consideration of Leadership in Energy Environment
and Design (LEED) designs and materials standards, and recognised sustainable building materials. The research
methodology adopted in carrying out this research is case study research methodology and comparative research
analysis method because of their proven effectiveness in Architectural Research. the research contain design
analysis carried out on case studies, these case studies revealed that Mixed use vertical developments require
much energy and adopts nonrenewable energy means to meet their energy needs for optimum functionality,
thereby releasing much carbon dioxide into the environment. The carbon dioxide released into the atmosphere
results in ozone layer depletion by contributing negatively to climate change and human well-being. These
challenges were further taken into consideration in addressing the design challenges and were greatly considered
in arriving at a design solution to enhance the optimum function of this project design and ensuring it meets vision
2050 of International Union of Architect of an energy efficient and less carbon emitting building projects. This is also
in agreement with SDG 11 goal of sustainable cities and contributing positively to climate in addition to human well
being. The design project thus goes further to improving on the planet as a livable built environment while ensuring
that the project design gives high-performance leverage to its users and guaranteed return on investment to
investors.
