Purpose The purpose of this paper is to determine the approximate window-to-wall ratio (WWR), window width-to-height ratio (WHR) and sill level for a room in Rasht–Gilan province and to present an optimal window in each of the WWR ranges providing the minimum energy consumption by integrating...

Purpose Sustaining the irrigated agriculture, while conserving the natural eco-system, are the two main objectives of sustainable water management (SWM) in irrigation. Achieving both the objectives simultaneously is a complex task in most developing countries. This requires a holistic approach...

Purpose This paper searches for integration methods proposed by different authors that assess the life cycle of a building using models of building information modeling (BIM) and it also compares and discusses them. Design/methodology/approach Systematic literature review (SLR) is selected as...

Purpose It is no surprise that garbage is not garbage for some. It is money. This is why garbage has been overestimated to a point that money allocated for waste-to-energy (WtE) projects feed individual pockets. Many countries have already adapted WtE as a successful solution for both energy and...

Purpose The purpose of this paper is to select a suitable procurement method for steel building construction in Sri Lanka following a systematic method which weigh, both procurement selection factors and existing procurement systems. Design/methodology/approach An abductive research stance is...

Purpose The built environment is well known for carbon emission and its impact especially as it pertains to existing buildings. This has culminated in an increasing need for a retrofit of such buildings. This study details the development of an artefact for improving the delivery of energy...

Purpose Road projects have been characterized by risk factors impacting project objectives. Thus, this paper focused on evaluating the effect of risk on cost and time performance of some selected road projects. Design/methodology/approach Using the theory of two-dimensional nature of risk, a...

Purpose This paper examines the use of intelligent technologies in buildings and whether the use of smart technologies impacts the circular economy performance of buildings in terms of energy and water consumption, their marginal cost and the management decision time and quality, for building...

Purpose Sustainability considerations are often treated as an add-on to building design, following ad-hoc processes for their implementation. The purpose of this study was to investigate, model and facilitate the early stages of building information modelling (BIM) enabled sustainable building...

Purpose As a response to the growing operational and disruptive threats to water distribution networks (WDNs), researchers have developed a vast array of methods for the reliability analysis of WDNs. In order to follow this growing number of methods, this paper reviews and documents in one place...
