“…New material and designs such as photovoltaic glasses (Sdringola et al, 2014), double glazing with a circulating water chamber (Gil-Lopez and Gimenez-Molina, 2013) and combinations of sucrose and PMMA (Gutierrez and Zohdi, 2014) have a good effect on the thermal insulation of the building, which can save energy consumption of the building and thus reduce carbon emissions. In addition, some natural material such as sugar construction products (Gopinath et al, 2018) and natural insulation material (Sagbansua and Balo, 2017) and artificial material such as PEX (Asadi et al, 2016), transparent silica aerogel (Dowson et al, 2012) and Atactic polypropylene (Vaz and Sheffield, 2014) have a better green performance in the construction industry.…”

Purpose Addressing global warming challenge, carbon emissions reduction potential of the construction industry has received additional attentions. The decoupling of construction industry and carbon emissions through policies, technologies and model innovations is an effective way for reducing environmental pollution and achieve eco-urban target. The paper aims to discuss these issues. Design/methodology/approach Within the scope of green building carbon emissions (GB-CO2) research, a large number of scientific literature has been published in construction discipline over the past few decades. However, it seems that a systematic summary of strategies, techniques, models and scientific discussion of future direction of GB-CO2 is lacking. Therefore, this paper carries out data mining on authoritative journals, identified the key research topics, active research areas and further research trends through visualization studies. Findings This study contributes to the body of knowledge in GB-CO2 by critically reviewing and summarizing: professional high-quality journals have a greater influence in the scope of research, developed countries and developing countries are all very concerned about sustainable buildings, and the current hot topics of research focus on the application of the life cycle models, energy efficiency, environmental performance of concrete material, etc. Moreover, further research areas that could expand the knowledge of cross-national long-term carbon mechanisms, develop comprehensive life cycle carbon emissions assessment models, build technical standards and tests for the sustainable building material and systems, and exploit multi-objective decision models considering decarbonizing design and renewable energy. Originality/value This study is of value in systematic insight the state-of-the-art of GB-CO2 research in the more recent decade. A more vividly and effectively method is documented in extending the traditional bibliometric review to a deeper discussion. This study can also benefit construction practitioners by providing them a focused perspective of strategy and technologies innovations for emerging practices in green building projects.

“…Ozel studied the effect of the exterior surface solar absorptivity on the thermal characteristics and optimum insulation thickness [19]; conducted a cost analysis for the optimum thicknesses and assessed the environmental impact of different insulation materials [20]; carried out a thermal, economic and environmental analysis of insulated building walls in cold climates [21]; and studied the effect of the glazing area on the optimum insulation thickness for different wall orientations [22]. Sagbansua and Balo [23] studied the potential use of eco-efficient materials in buildings instead of conventional materials using the optimum insulation thickness method, considering both the ecological impact and the financial feasibility. In addition, in the Mediterranean environment, Annibaldi et al [24] studied the environmental and economic benefits of the optimum insulation thickness using a life cycle cost analysis of historic buildings in Italy, and Derradji et al [25] determined the energy savings due to glazing effects on the optimum insulation thickness in a classic home in Algeria.…”

Energy Renovation of Residential Buildings in Cold Mediterranean Zones Using Optimized Thermal Envelope Insulation Thicknesses: The Case of Spain

et al. 2020

The residential sector of the European Union consumes 27% of the final energy of the European Union, and approximately two-thirds of the existing dwellings in the European Union were built before 1980. For this reason, the European Union aims to transform the existing residential building stock into nearly zero-energy buildings by 2050 through energy renovation. The most effective method to achieve this goal is to increase the thermal insulation of opaque elements of the thermal envelope. This study aims to assess the energy, environmental and economic impacts of the energy renovation of the thermal envelopes that are typical of the existing multi-family buildings of the 26 provincial capitals in the cold climate zones of Spain. To achieve this goal, the insulation thickness to be added to the walls, roof and first floor framework is optimized by a life cycle cost analysis, and the existing building openings are replaced, thus minimizing both the total heating costs and the total heating and cooling costs. The study uses four thermal insulation materials for four different heating and cooling systems in 10 different models. The results obtained will be used to propose energy renovation solutions to achieve nearly zero-energy buildings both in Spain and in similar Mediterranean climate zones.

“…In most studies, this analysis is performed using the degree-time method (degree-day or degree-hour). This approach is a simple technique pertaining to the steady state [20,[36][37][38][39][40][41][42]. However, the degree-time method, in most cases, does not take into account the non-constant operation schedule (lighting, occupancy and equipment), the heat storage effect of walls and the characteristics of the heating and cooling system in the calculation of the heat transfer through the external wall [43].…”

To delay fossil energy depletion and implement the Paris Climate Change Accord, the South Korean government is attempting to reduce greenhouse gas emissions with the establishment of the 2030 Roadmap. The insulation performance of external walls is being continuously enhanced in the architectural domain. However, Korea’s policy and construction market focuses only on the heat resistance of buildings’ external walls to enhance the insulation performance, leading to an increased thickness of the insulation materials. In this study, the relationship between the surface reflectivity and insulation thickness of external walls was examined to formulate an effective insulation strategy for buildings in Korea. Office buildings of 12 regions in the Korean Peninsula were considered. The dynamic energy simulation program EnergyPlus was used to perform the heating and cooling load analyses. The present worth method was adopted to perform the economic analysis. The analysis of the cooling and heating loads indicated that a change occurred not only in terms of the latitude but also between the Eastern and Western regions. The energy consumption could be reduced by increasing the reflectivity in the Southern region and lowering the reflectivity in the Northern region, based on the total load. In addition, a higher latitude corresponded to a higher energy saving effect owing to the increased insulation thickness. In the case of Jeju Island and Busan, regions with a relatively large cooling load and small heating load, the total load is little affected by insulation thickness at high reflectivity. If the external skin was considered to have the optimal reflectivity, the regions for optimal insulation thickness could be divided into three categories: north, central and south.
