Carbon dioxide (CO2) emissions are a serious hazard to human life and the ecosystem. This is the reason that many measures have been put in place by the International Energy Agency (IEA) to reduce the anthropogenic-derived CO2 concentration in the atmosphere. Today, the potential of renewable energy sources has led to an increased interest in investment in carbon capture and storage technologies worldwide. The aim of this paper is to investigate state-of-the-art carbon capture and storage (CCS) technologies and their derivations for the identification of effective methods during the implementation of evidence-based energy policies. To this extent, this study reviews the current methods in three concepts: post-combustion; pre-combustion; and oxy-fuel combustion processes. The objective of this study is to explore the knowledge gap in recent carbon capture methods and provide a comparison between the most influential methods with high potential to aid in carbon capture. The study presents the importance of using all available technologies during the post-combustion process. To accomplish this, an ontological approach was adopted to analyze the feasibility of the CCS technologies available on the market. The study findings demonstrate that priority should be given to the applicability of certain methods for both industrial and domestic applications. On the contrary, the study also suggests that using the post-combustion method has the greatest potential, whereas other studies recommend the efficiency of the oxy-fuel process. Furthermore, the study findings also highlight the importance of using life cycle assessment (LCA) methods for the implementation of carbon capture technologies in buildings. This study contributes to the energy policy design related to carbon capture technologies in buildings. [ABSTRACT FROM AUTHOR]

- Abstract
End-of-life tires are a common and hazardous type of waste. According to estimates, over 2 billion tires are produced each year, and all of these tires will eventually be discarded as waste. Landfilling waste tires is strictly prohibited by the regulations of the European Union and the Environmental Protection Agency; they should be retreated and reused in an alternative scenario. As a waste-to-energy technology, pyrolysis can emerge as a useful technique to thermally degrade waste tires and produce useful byproducts in the form of liquid, gas, and char. The derived products can be filtered and used in further industries as biofuel substances. Pyrolytic oil has a high calorific value of 35–45 MJ/kg and can be used as an alternative to diesel to fuel specific vehicles. However, the environmental footprint of the technology has been widely neglected when using waste tires as feedstock. Made from synthetic and natural rubbers, tires contain a high amount of sulfur and styrene, which can cause toxic emissions and negatively affect the environmental sustainability of pyrolysis. This concept paper aims to elaborate the parameters of an operating rotary kiln reactor by reviewing previous life cycle assessment studies and applying the methodology to an industrial-scale pyrolysis plant in Northern Cyprus. Results found a maximum production yield of 45.6% oil at an optimal temperature of 500 °C. Influential parameters such as temperature, residence time, and heating rate are reviewed based on their overall contribution to the production yield and the environment. The outcome of this paper emphasizes the need in the literature to apply environmental analyses to industrial and commercial-scale reactors to test the sustainability of using pyrolysis as a tire waste management strategy. In addition, complex engineering concepts and tasks in waste recycling will be discussed in a broad and accessible manner, with the implications and future work discussed. [ABSTRACT FROM AUTHOR]

- Abstract
To maximize profits without sacrificing quality, the concept of sustainable construction must be adopted across a project's whole lifespan. Although adopting the idea of passive design in developing countries is incomplete, these studies have focused on the reasons for doing so. In contrast, there is limited evidence to completely analyze the influence of integrating passive design on the project sustainable success (PSS) of projects throughout their existence. This study focuses on the hurdles to passive design adoption in Pakistani building projects. It evaluates the impact of overcoming passive design (PD) adoption barriers on project sustainability success (PSS) during the duration of the project. Therefore, a more comprehensive literature assessment is required for conceptual model construction. Using a survey assessment instrument, Structural Equation Modeling (SEM) was constructed (i.e., a questionnaire). A total of 156 construction experts in Pakistan provided information. The result of the model demonstrated that the elimination of PD implementation obstacles had a moderate to high impact on PSS throughout the building structure's lifetime. These results provide the foundation for legislation in a number of Asian nations about the efficient completion of projects via the removal of obstacles for the use of passive design. Similarly, the adoption of passive design will increase the success of the construction project. [ABSTRACT FROM AUTHOR]

- Abstract
Passive design strategies can reduce heating and cooling demands with integration of more efficient building systems as well as the potential to integrate modular off-site construction technology and its technical systems to offset overall energy consumption. This study evaluates the energy performance of the nationally representative post-war social housing estate in the southeastern Mediterranean island of Cyprus where the weather is subtropical (Csa) and partly semi-arid (Bsh). This study employed a mixed methods research design approach which was based on a thorough field study that consisted of a questionnaire survey conducted with residents of the social housing estate in the hottest summer month of August, to explore the occupants' thermal sensation votes (TSVs), their habitual adaptive behaviour, and home energy performance concurrently. On-site environmental monitoring was performed, and in-situ measurements of each occupied space were recorded to identify 'neutral' adaptive thermal comfort. The selected representative high-rise residential development was modelled using Integrated Environmental Solutions' Virtual Environment (IES-VE) software, where extensive dynamic thermal simulations have been produced to assess existing energy performance and energy effectiveness of retrofitting strategies. The results demonstrated that a moderate–strong relationship was found between orientation and reasons for thermal discomfort (χ
2 = 49,327, p < 0.001, Cramer's V = 0.405). Individual levels of thermal comfort were not limited to household socio-demographic characteristics, however; environmental factors were also determinants in the development of adaptive thermal-comfort theory. Furthermore, the occupants' TSVs indicated that in a southeastern Mediterranean climate, 28.5 °C is considered a neutral temperature, and the upper limit of the indoor-air thermal-comfort range is 31.5 °C.

Problems on mass housing estates are currently a topic for research on energy and policy interventions in Cyprus. Modernist urban detached/semi-detached and suburban row houses often have insufficient green areas and lack consideration of the climatic features of the building site where the neighbourhoods are designed without concern for urban planning laws and regulations. These purpose-built residential building stock models represent 30% of the existing building stock. This research primarily investigates the potential of particular design interventions in detached two-storey houses in a Mediterranean climate in order to reduce the need for fossil fuel to heat and cool the houses. The aim of this study is to develop and test feasible retrofit strategies aimed at optimising the energy performance of the existing residential buildings. To accomplish this, the study first examines the energy performance of a building before and after the retrofitting phases as base case scenario models. The Autodesk Revit 2017 plug-in Green Building Studio energy performance analysis software was used for simulation of the adapted energy-efficient retrofit measures. This study also outlines the results from the prototype analysis to demonstrate the difference between a retrofitted building and the existing state of a building in their respective energy use impacts.

Highlights • To ensure systematic analysis of the key aims and objectives, this research adopts an 'explanatory research design'. • The study focuses on a 'case study' approach in order to carry out analysis of the most representative housing typology in Famagusta, Cyprus. • The possible sustainable green urbanism features and architectural measures in the scope of local land use policy requirements were evaluated. The feasible scenarios were devised by adding the topographical characteristics of selected case study locations of all designed maps were undertaken. Abstract Problems in mass housing estates in Famagusta, Cyprus, have been an issue for research on urban planning and policy interventions for many years. Neighbourhoods were designed featuring modernist residential tower blocks and suburban row houses with insufficient green areas and no consideration of either the climatic features of the built site or of urban planning, regulations or law. This study discusses ongoing, uncontrolled construction trying to change the contemporary urban environment, based on the features of housing and urbanism. It investigates whether the natural landscape and extensions to topography have played decisive roles in the construction of mass housing estate developments and uses of the rural periphery of the city. The study develops a base case of urban transformation models representing the morphological characteristics of buildings from three distinct construction eras (the 1970s, 1990s and 2010s). The information collected is enriched and verified by a site survey. Through three case studies, the types of buildings in each era are analysed and evaluated in relation to a number of environmental factors, including an analysis of the different context layers, to ascertain the existing strength of the urban block development configurations as well as to evaluate their shortcomings under the threat of urban sprawl. The findings not only provide ground research for developing urban retrofit scenarios but also employ sustainable planning tools based on those urban processes. [ABSTRACT FROM AUTHOR]

- Abstract
This research project is undertaken in the Turkish Republic of Northern Cyprus (T.R.N.C.). The objective of the research is to investigate the occupants' behaviour and role in the refurbishment activity by exploring how and why occupants decide to change building systems and how to understand why and how occupants consider using energy-efficient measurements. The housing estates are chosen from 16 different projects in four different regions of the T.R.N.C. that include urban and suburban areas. The study is conducted through semi-structured interviews to identify occupants' behaviour as it is associated with refurbishment activity. This paper presents the results of semi-structured interviews with 70 homeowners in a selected group of 16 housing estates in four different parts of the T.R.N.C. Alongside the construction process and its impact on the environment, the results point out the need for control mechanisms in the housing sector to promote and support the adoption of retrofit strategies and to minimise non-controlled refurbishment activities. The results demonstrate that European Union Energy Efficiency directives need not only inform households about technological improvements that can be installed in their residential properties, but should also strongly encourage and incentivise them to use them efficiently. Furthermore, the occupants' energy consumption behaviour and the applicable policy interventions will make the difference between implementing policy which in fact delivers on its aims for energy efficiency and sustainability.

RETROFITTING ,ARCHITECTURE & energy conservation - Abstract
This research project was undertaken in the Turkish Republic of Northern Cyprus (T.R.N.C). The objective of the research is to investigate the occupants’ behaviour and role in the refurbishment activity; to explore how and why occupants decide to change building components and to understand why and how occupants consider using energy-efficient materials. The study is conducted through semi-structured interviews to identify occupants’ behaviour as it is associated with refurbishment activity. This research paper presents the results of semi-structured interviews with 70 homeowners in a selected group of 16 housing estates in four different regions of the T.R.N.C. The expected solutions should be effective, environmentally acceptable and feasible given the type of housing projects under review, with due regard for their location, the climatic conditions within which they were undertaken, the socio-economic standing of the house owners and their attitudes, local resources and legislative constraints. Furthermore, the study goes on to insist on the practical and long-term economic benefits of refurbishment under the proper conditions and why this should be fully understood by the householders.
