- Description: Abstract : This research examines the potential impact of domestic anaerobic digester (AD) systems adopted in Bangladesh and similar developing countries. Cattle dung and poultry litter feed stocks were specifically investigated, because these were freely available and plentiful to people living within agricultural areas of rural Bangladesh. Data was collected to ascertain whether these two representative AD facility types provide tangible social, economic and environmental impact that benefits homeowners. Primary quantitative and qualitative data was obtained by field data collection, and meeting with expert groups and stakeholders. Empirical analysis conducted revealed that variations were found in the biomass feedstocks available on different sites but also differences were apparent in terms of the operations and maintenance (O and M) systems of the biogas plants operated. The biogas and methane yield variation was also measured, and variations were found in the cattle dung and poultry litter AD yield capacity. Overall, 64% of feedstock was utilised, 91% of biogas plants remain underfed and energy yield efficiency was 57% from cattle smallholdings’ AD and 28% from poultry farms’ AD. These results showed that small scale AD can offer a significant impact upon rural lifestyles through augmented economics, improved social activities, relationship building with neighbours and improved lifestyle achieved via time savings accrued. These results could help rural entrepreneurs, AD equipment providers and government institutions to develop a road map to implement future AD installation on a much wider geographical scale.

- Description: Abstract: Selection of suitable building material options are being influenced by various stakeholders in the construction industry, The process of selecting these material options can be very complex, being influenced and determined by numerous preconditions, decisions, and considerations. It should however, be noted that stakeholders are legally responsible for the project and their importance can be reflected by the various ways they influence the adoption of innovation strategy. Therefore, this research attempts to identify the possible factors that influence the selection of building materials for housing projects from the perspective of stakeholders in the Ghanaian construction industry. 47 possible factors influencing the selection of building materials for housing projects were identified through literature review. Interviews were carried out prior to the questionnaire survey to examine the relevance of the identified factors in the Ghanaian context. The interviews were conducted amongst eight purposively selected top architectural and structural engineering firms operating in Ghana. Questionnaires were also distributed to a sample of 150 stakeholders in the Ghanaian construction industry, out of which a total of 138 were returned and then analysed using Statistical Package for Social Sciences (SPSS). Relative Importance Index was used to rank the selected factors according to their order of importance. The ten most important building materials selection factors identified in this study are: strength, durability, initial cost, appearance (aesthetic value), water resistance, owner's/user's choice, availability of materials, resistance to decay, heat resistance, and fire resistance. The research concluded that stakeholders in the construction industry should consider all the important factors identified in this study when selecting building materials for housing project in Ghana.

- Description: Abstract: Emphasis on the importance of innovation within the construction industry to a larger extent has received an increased call. The need for the construction industry to facilitate technological innovations in order to maintain a competitive edge in the market lower Construction cost, improve quality, maximize productivity and meet the infrastructure need of the economy has been further emphasized. Realization of this increased importance of innovation will be nullified if the barriers to implementation of innovation are not understudied with provisions of stringent measures to mitigate the barriers to innovation. This exploratory paper analyses the barriers to implementation of construction innovation in the construction industry and likewise proposes measures of reducing the barriers to construction innovation. The research methodology includes extensive literature review supported with and random interviews. In all thirty (30) contractors, clients and construction association professionals were contacted via structured interviews to ascertain the existence and severity of the barriers. Findings from the study revealed that some of the barriers to construction innovation include: industry barriers, organizational barriers, legislative and regulatory barriers amongst others. It is recommended that effective collaboration within the construction sector and its stakeholders should be fostered in order to facilitate construction innovation as evidenced from other industries. Moreover, the formulation and cooperation of governmental and institutional policies which does not suppress construction companies must be established.
