A REVIEW OF AWARENESS LEVEL AND PRACTICES OF GREEN CONSTRUCTION

A REVIEW OF AWARENESS LEVEL AND PRACTICES OF GREEN CONSTRUCTION

​​​​​​​Background to study

Green or sustainable buildings are the way of the future and will become more popular in Nigeria during the next few decades. The desire for high-performance buildings is progressively becoming a trend in the Nigerian construction sector. The primary goals of sustainable construction operations are to minimise resource depletion of energy, water, and raw materials, as well as to prevent environmental degradation caused by buildings and infrastructure throughout their entire cycle (Nordic Research Institute, 2015). According to Nwokoro and Onukwube (2016), the implementation of an efficient waste management system, the use of renewable building materials, and the appropriate use of project design facilities will help Nigeria achieve biophysical sustainability. To achieve sustainable construction, the sector is expected to develop its building methods. Building construction has increased dramatically, accounting for nearly half of all greenhouse gas emissions and energy consumed, owing primarily to the energy used in the production and transportation of materials to building construction sites, as well as the energy used to operate these buildings (Adegbile, 2018). The built environment accounts for a significant portion of material and energy use, biodiversity loss, pollution, and trash creation (Afolabi, 2018). Designing for flexibility, durability, adaptability, and quality are critical considerations in achieving technical sustainability in building (Nwokoro, 2011). The construction sector contributes significantly to the bulk of environmental problems (Celik, 2013). Green design assures that no portion or component of the structure endangers the environment. This necessitates the use of natural construction materials containing organic molecules, such as wood, bricks, or other elements, rather than synthetics (Daramola, Adebayo & Alabi, 2016). Sustainable development is development that satisfies the requirements of the present without jeopardising future generations' ability to satisfy their own needs (United Nations, 1987). According to Nduka and Ogunsanmi's (2015) study on the Adoption of Green Building Practices in Construction Projects in Nigeria, professional organisations should train and educate their members on green principles to guarantee awareness and knowledge of the practise. Professionals must attend seminars, conferences, and training programmes to expand their understanding of green design, construction, methodologies, and procedures in order to maintain successful sustainable practise on projects. Green or sustainable design aims to minimise energy, operation and maintenance costs, reduce building-related sickness, boost productivity and comfort of building occupants, reduce waste and pollution, and increase building and component durability and adaptability. It is critical to include green concepts into building design, planning, and construction from the beginning. There is a need to lower the requirement for energy in buildings and raise knowledge about the effective use of available energy (Malina, 2013).

 

As a result, it is critical to support green construction and guarantee that it is integrated throughout the design stage of the project. Public awareness about green construction in Lagos is limited due to a lack of institutional structures promoting green buildings, a lack of adequate resources to promote green construction, little or no government incentives to promote green construction, limited professional capacity to integrate green building into construction, and little or no government encouragement to initiate green construction. This research is aimed at evaluating the factors restraining the practice of green construction in Lagos state.
