“…These results highlight the low importance of timber in KRI constructions and therefore the possibility of using them to increase the number of timber buildings. Notice that this is in accordance with Espinoza et al [61] and Mallo and Espinoza [62]. These studies on the use of EWPs in United States showed that participants thought that, in general, the level of awareness about EWPs among developers, construction managers, engineers, architects, and construction managers is low.…”

The use of timber in the building industry has expanded in many countries over the last 20 years due mainly to its light weight, low adverse impact to the environment, and fair mechanical properties. Despite the development of the construction industry in the Kurdistan Region in Iraq (KRI) in recent years, timber product utilization is still very limited. Therefore, the purpose of this study was to investigate the feasibility of further utilizing timber-based products in the building industry in semi-arid regions using the KRI as a case study. A review of timber product utilization in the region was conducted first and the general properties of timber products were followed. Based on this, a survey focusing on the current situation and suitability of localized grown timber products was carried out to study the feasibility. This article concludes that the use of timber-based products in the KRI presents different barriers, with the availability in the market and technicality of construction with the material being the strongest ones. The article recommends that it is imperative to further research how to promote timber’s utilization in the KRI to be in line with sustainable development.

“…Furthermore, farmers are not allowed to cultivate any form of hemp in Ghana, as this is a criminal offence and can result in a 10-years prison sentence even for small amounts (Seeds, 2020). A recent study stresses the potential use of vernacular building materials like timber, bamboo and laterite to deliver green buildings, especially in Ghana (Agyekum et al, 2020). Despite the abundance of the literature on sustainability and enormous advocation for the use of such sustainable materials as better alternatives for reducing the adverse effects caused by the production and use of conventional materials in Ghana (Agyekum et al, 2020), there is a lack of studies about the potential use of hemp as a sustainable building material.…”

PurposeThe increased awareness of global environmental threats like climate change has created an upsurge of interest in low embodied carbon building materials for green building delivery. Though the literature advocates for the use of hemp-based building materials, there is no evidence of studies to explore its potential use in Ghana. Therefore, this study explores the potential factors that limit the adoption of hemp as an alternative sustainable material for green building delivery in Ghana.Design/methodology/approachA structured questionnaire was used to solicit the views of built environment professionals operating in construction, consulting and developer firms. The questions were developed through a comparative review of the related literature and complemented with a pilot review. Data were analysed via descriptive and inferential statistics.FindingsOn the average, the majority of the respondents showed a moderate level of awareness of hemp and its related uses in the construction industry. Also, certain key factors like the perceived association of hemp with marijuana, lack of expertise in the production of hemp-related building materials, farmers not getting the needed clearance for the cultivation of hemp, lack of legislation by the government in the legalisation of hemp and the inadequate knowledge of consumers on the benefits of hemp-based building materials were identified as potential limitations to the adoption of hemp as an alternative sustainable material for green building delivery.Originality/valueThe findings from this study provide insights into a less investigated area in sub-Saharan Africa and further provide new and additional information to the current state-of-the-art on the potential for the use of hemp in the building construction sector.

The concept of green architecture, also known as "sustainable development" or "green building," is the theory, science, and style of buildings designed and built based on environmentally friendly principles. Green architecture seeks to minimize the number of resources used in the construction, operation, and management of the building and limit the damage caused to the environment by spreading, pollution, and waste of building components. New water and materials are used to design, build, operate and conserve building energy and generate large amounts of waste that negatively affect health and the environment. To limit these effects and design environmentally sound and resource-efficient buildings, the concept of "green building systems" needs to be introduced, clarified and understood, and practiced. One of the solutions is to use green building methods in the construction industry in today's world. Demand for sustainability as a definitive solution to all environmental challenges Inspired by this research to emphasize the priority of increasing sustainable environmental productivity to reduce carbon emissions to discuss and demonstrate sustainable buildings in Iran (new and existing) and Presenting the principles of energy audit used in them and their performance toward standards. Meanwhile, Iran is ranked as one of the good countries in building growth and green energy in the Middle East and other countries, according to the US Green Building Council's ranking of energy consumption, renewable energy, and recycled materials in 2015-2016.
