Significant Attention

Considering the rate of depletion of the available oil-based fuels, Renewable Energy Technologies are receiving significant attention in these years. It is, therefore, necessary to find alternatives to energy sources. This project focusses on one such alternative. A study is done on a vehicle suspension system and braking system. Suspension in vehicles produces linear vibrations due to the roughness on the roads. These vibrations are absorbed the shock absorbers and dissipated in the form of heat. In the case of a conventional braking system,a huge amount of heat is lost due to friction. This study proposes a design of a system where the heat lost in the suspension system is extracted, converted into a usable form of electrical energy and stored in batteries. This stored energy is further used in the operation of electromagnet powered brakes. Using the Regenerative Suspension System reduces the waste of energy in the shock absorbers and gives an alternative energy source and use of the Electromagnetic Braking System ensures frictionless braking. Thus, the overall consumption of energy is reduced by a notable amount.

The success of every construction projects largely depends on the level of commitment of the clients. This study examined the factors influencing the level of clients’ commitment to sustainable construction practices in Nigeria. A questionnaire survey was use to collect data from the public and private construction clients on the level of influence of 16 factors extracted from the literature. A total of 182 valid questionnaires were used for analysis. The result revealed that nine factors with weighted average (W) 0.8≤W≤1 have a high level of influence, whereas seven factors with 0.6≤W≤0.8 have a high-medium level of influence on the clients’ commitment. However, the five most influential factors were: client knowledge and awareness, Cost implication and mechanism of financial involvement, economic value and return on investment, end-user/client perception and preference, and health and safety implications. The result further revealed that there is significant difference on how these factors influence the level of commitment of sustainable construction practices of the public and private clients. The study suggested that the disparity was due to the differences in the level of knowledge, awareness, involvement and commitment of the public and private clients to sustainable construction concept. Hence, it is important to optimize the level of knowledge and awareness of the clients, about the cost, benefits/profits, and health and safety implications of sustainable construction practices so as to promote the level of client’s commitment to sustainable construction practices. It recommended for adequate client involvement throughout the sustainable construction life cycle and a sustained awareness campaign, championed by relevant government agencies and professional organizations through different public programs so as to increase the clients’ commitment and desirability to demand for more sustainable construction projects.
