Published: September 2019

Abstract
It has been well accepted that applying recycled aggregate concrete (RAC) into structural engineering is a sustainable method to solve the problem of construction and building waste (CDW) accumulation meanwhile to save natural resources exploitation. Precast RAC members in factories is beneficial to improve their qualities and will extend the RAC application. This study presents nonlinear damping behaviors of precast and cast-in-situ RAC frames after simulated earthquakes, as a reference of quality control of precast RAC members, and of damage detection under ambient vibration. The nonlinear damping of precast RAC slabs with different damage degrees was studied to validate the feasibility of applying the quadratic damping coefficient as a sensitive damage factor without any requirement of undamaged baseline. Meanwhile a comparative study on nonlinear damping behaviors of a precast and a cast-in-situ RAC frames was conducted. Results highlight a change of nonlinear damping mechanism for both precast and cast-in-situ RAC frames from a viscous damping into a nonlinear damping. The precast RAC frame had a comparatively larger quadratic damping coefficient before and after earthquake hitting, indicating it had more severe initial damage and damage developed more significantly compared with the cast-in-situ frame. A unified damage classification was proposed for both precast and cast-in-situ RAC frames based on quadratic damping coefficient and observation.

Abstract
The growing need to shift from a linear to a circular economy has inspired producers of building materials and systems to innovate their products to match the requirements of a future circular economy. Others have been developing modular systems in the past to simplify the building process and are now reconsidering these products for their potential in a circular economy. However, at this early stage on the road towards a circular economy, claims of circularity are often made too easily and many producers as well as architects and builders are still struggling with the practice of circular building. In this context and within an assignment for master students in architecture, three cavity walls, each 9m2 and composed with a different system for the inner and the outer wall, have been constructed and disassembled in order to test their potential for circularity. The extent of circularity has been critically analysed with an existing framework of evaluation criteria for design for change: three criteria on interface level (reversibility, simplicity, speed), three on component level (compatibility, durability, manageability) and three on composition level (independence, pace-layering, prefabrication). This analysis was complemented with an environmental assessment of the materials used and with interviews with contractors who have experience with these systems. In a final step, proposals for improvement of the products and systems have been made and tested on a mockup scale, in order to better fit a possible future circular economy.

Authors: Medgyasszay P 
Published: September 2019

Abstract
The paper examines a public building constructed of partially natural materials and two imagined buildings with the same geometry, using LCC and LCA methods, with self-developed software. The imagined buildings were designed using the building materials and building mechanical systems commonly used in Hungary which fulfil the relevant energetic requirements in 2010 and in 2019. As a sensitivity analysis the LCA performance of buildings was examined with residential building function. The paper introduces the environmental benefits that can be obtained with natural materials and with other tools in case of the examined building. Based on the results, design strategies can be phrase for environmentally conscious design of buildings with similar scale and function.
Linking construction timber carbon storage with land use and forestry management practices
Authors: Forster E J , Healey J R , Dymond C C , Newman G , Davies G , Styles D 
Published: September 2019

Abstract
Consequential life cycle assessment was applied to forestry systems to evaluate the environmental balance of expanding forestry onto marginal agricultural land to supply more timber for the built environment, accounting for land use effects and product substitution. Forestry expansion to supply timber buildings could mitigate UK greenhouse gas (GHG) emissions by 2.4 Gg CO2 eq. per ha of forest over 100 years, though net mitigation could be halved if beef production were displaced to Brazil. Forest thinning increases wood yields and percentage conversion of harvested wood to construction sawnwood, resulting in 5% greater net GHG mitigation compared with unthinned systems. Optimising the environmental sustainability of construction timber value chains in a circular, bio-based economy will require holistic accounting of land use (change), forestry management and complex flows of wood.

Abstract
European Directive (EU) 2018/844 amending Directives 2010/31/EU (EPBD) and 2012/27/EU (EED) aims at decarbonizing the European building stock. Energy efficiency measures and renewable energy use play an important role, especially regarding retrofit of existing buildings. Identification of retrofit opportunities and aggregation of projects to benefit from economy of scale are a precondition for the implementation of large-scale renovation projects. The ENERFUND project, funded by the HORIZON 2020 programme, provides data from Energy Performance Certificates according to EPBD publicly available in the form of a map and combines them with other geo-referenced data and general information to allow for the rating of deep renovation and carbon reduction opportunities. In this way, the tool assists in identifying retrofit opportunities and aggregation of projects for financing. It also assists in supply-side energy spatial planning, because it shows where energy consumption is likely to decrease due to economic renovation potentials. This contribution shows an overview of data available for thirteen European Member States. Data sources and differences regarding the type of data are explained, and challenges such as data quality issues and data protection concerns are discussed. It is demonstrated that the ENERFUND tool certainly assists in decarbonizing the European building stock, although some improvements are still necessary.
Energy transition and technical energy regulations in the building sector
Authors: Knoeri C , Schwarz M , Nakhle C 
Published: September 2019

Abstract
Energy demand from buildings accounts for about 31% of global final energy demand and 23% of global energy-related carbon emissions. Technical energy regulations or building energy codes - policies that set minimum requirements for energy in buildings – have proven effective and efficient in decarbonizing the building sector. However, despite their long history and success, policymakers increasingly recognise that TERs in their current design have reached a point of diminishing returns. This study evaluates five countries with innovative building energy codes – Denmark, France, England, Switzerland, and Sweden – through reviewing legal documents and conducting expert interviews with researchers, practitioners, and regulators. Our results highlight the implementation challenges of innovative building energy codes and we provide learnings in form of six design principles.
Towards conceptual understanding for the adoption of building environmental sustainability assessment methods in the UAE built environment

Published: September 2019

Abstract
The UAE is witnessing increased interest for sustainable development which poses challenges on the development processes for the large amount of built environment projects taking place in this emerging economy. While, great attention has been given to the development of tools and methods to measure and assess the performance of buildings to meet specific environmental sustainability targets, however, less is known about the effect of these assessment methods on the built environment development process itself. This paper addresses this gap through the investigation of the adoption of building environmental sustainability assessment methods for development projects in the UAE. Currently, there are two assessment methods in the UAE; Pearl Building Rating (PBR) and Al Sa’fat systems. Background study revealed that both systems: are developed in parallel to the development of building codes, adopt performance-based approach for assessment methods, and their adoption for development projects is basically mandatory. This paper draws from diffusion of innovations theory and growing literature in the adoption of similar assessment methods in projects, with the objective of proposing a conceptual framework that conceptualizes PBR and Al Sa’fat methods as innovations and the development projects as the social system for adoption, while focusing on the adoption process dynamics rather than the decision to adopt or not. The proposed framework captures specific conceptual themes, providing the foundation for further empirical investigation. As such, this paper contributes to the growing literature on the adoption of global energy assessment tools and specifically addresses the UAE’s sustainable development policy and regulation.

Published: September 2019

Abstract
Lack of safety awareness has caused many losses including accidents cost, insurance cost as well as indirect costs. Most of work accidents occurred due low perception of work safety. A measurement of safety climate for workers and head department should be considered to figure the condition of safety climate out. The assessment of safety climate is using Nordic Safety Climate Questionnaire (NOSACQ-50). The significance of differences in the safety climate between workers and head department is determined by Mann-Whitney test. The study was conducted on 100 worker samples spread across 10 production departments and 10 head departments in a furniture manufacture. The result shows that the safety climate level is quite low at the management safety justice, workers’ safety priority and risk non-acceptance dimensions. The safety climate of head departments shows a good enough result on the 4 dimensions and need an improvement on the 3 other dimensions. There are differences in perceptions between workers and head departments on commitment and competence of management, the management safety justice, workers’ safety priority and risk non-acceptance dimensions.

Abstract
Based on the preliminary study and interviews to the Grand Medica Hospital Tanjung Anom Medan there are several problems, including the frequent delays of drugs and an increase in the percentage of disability drugs supplied by suppliers. Where the supplier is a top priority exactly shows the highest percentage of disability in the delivery period. From these problems, it is necessary to select the medicinal supplier of Grand Medica General Hospital by evaluating the criteria and subcriteria in the supplier assessment and will produce the output of more than one supplier that has been in accordance with the criteria. The purpose of this study is to assist the Hospital for making the right supplier selection decisions. Supplier selection is a matter of Multi Criteria Decision Making (MCDM) because in the selection process is done by evaluating each supplier which is seen some common criterion in supplier selection to fulfill requirement of raw material. The method used in this study is the method of Gray Based Rough Set Theory, where this m ethod will involve some decision makers who are considered to have an important role in this hospital. Gray Based Rough Set Theory is a combination of fuzzy or gray methods and rough sets. The selection of suppliers by this method also considers the importance of the decision maker by assigning weight to each decision maker. By providing the upper and lower limits of each calculation, this method is considered capable of producing better decisions, with the output of more than one selected supplier. Where the RSU Grand Medica currently needs suppliers to supply medicines to meet medical supplies at the Hospital. Based on the calculation of the value of the Gray Values factor, the results obtained for each supplier, namely supplier 1 (0.26), supplier 2 (0.31), supplier 3 (0.60), supplier 4 (0.60), supplier 5 (0.39), and supplier 6 (0.34). By analyzing the value of Gray Values factor, obtained the order of choosing the chosen supplier based on the weight of the biggest is supplier 4 (0,60), supplier 3 (0.60), supplier 5 (0.39), supplier 6 (0.34), supplier 2 (0.31), and the last supplier 1 (0.26).
