Abstract The concept of green buildings has recently arisen in order to contribute to solving some environmental, energy and economic issues. To meet the green building requirements, this paper describes an integrated design approach to improve the energy and water efficiency of the mid-rise residential buildings in Jordan using the eQUEST energy simulation tool. The results show that savings of 77.9% in the annual requirements of electricity, 65.0% in the requirements of diesel oil and 19.5% in the indoor water consumption can be achieved. Finally, the Jordanian green building model had achieved 44 points in the Leadership in Energy and Environmental Design green building rating system and will have the ‘Certified’ classification.

The Mediterranean Basin

Leadership in Energy and Environmental Design (LEED) has five basic categories: Sustainable sites (SS), Water Efficiency (WE), Energy and Atmosphere (EA), Materials and Resources (MR), and Indoor Environmental Quality (EQ). Additionally, in LEED 2009, the U.S. Green Building Council (USGBC) introduced regional priority (RP) points to adapt LEED to the local conditions of foreign countries. However, the appropriateness of the RP points stated for the Mediterranean basin has not yet been evaluated. Thus, we studied the similarities and differences in performances of LEED 2009 Commercial Interiors (CI) and LEED 2009 Core and Shell Development (C&S) Gold certified projects in Turkey, Spain, and Italy. We revealed that the categories without RP points, SS, MR, and EQ, performed similarly in all three countries, thereby signaling the correctness of CI and C&S applications in the Mediterranean basin. However, the categories with RP points, WE and EA, performed differently. It can be suggested that the following RP points would be beneficial for all three countries: (i) in the MR category, RP points that initiate decreases in virgin construction material; (ii) in the WE category, RP points that encourage water saving; and (iii) in the EA category, RP points that encourage using renewable energies.

PurposeThe demand for potable water increases with population growth, given its role in sustaining life. As part of a wider approach to ensuring sustainable provision, this has prompted a number of carefully formulated water efficiency improvement plans for buildings, one of the highest water-consuming sectors. This paper presents a detailed analysis of water efficiency potential for a multi-storey commercial complex and an office building in central Malaysia.Design/methodology/approachIn this study, a detailed analysis of the water use and efficiency of the water fittings was carried out. Important data such as historical water use and details of water fittings were acquired during a field survey. A series of water flow rate tests were conducted at the selected buildings and each of the water systems was analysed separately, using the criteria of water efficiency stipulated by a locally applied green building tool. A comparison of water consumption before and after the improvement plan was then made.FindingsFindings from the field surveys indicate that only some of the water fittings were certified with recognised efficiency ratings, which suggests a good opportunity for improvement. The proposed replacement of more-efficient fittings could potentially improve the obtainable green credit points by at least 10 from a maximum of 15. A cost–benefit analysis for a water fitting replacement scheme shows that the estimated payback period is less lengthy for the larger commercial building due to the higher potential savings.Practical implicationsStrategies for improvements in water efficiency for existing non-residential buildings are provided in this paper. The same water consumption analysis procedure can be used by maintenance engineers and other practitioners in building assessments where water efficiency and sustainability in building operation are of concern.Originality/valueThis case study responds to the need for efficient use of freshwater and provides insight into the water efficiency opportunities for commercial buildings. The potential cost savings for replacements of inefficient water fittings have been analysed using a green building tool as a guide. This has not been extensively analysed in previous studies.

Abstract Currently, climate change and wellbeing provoke buildings to have higher sustainable performance. So, the condition expects that buildings can tackle those issues that benefit and less impact the environment and its occupants. This particular target needs integrated design approach that the role of the iterative process is necessary. The study focuses on the process of facade design for the buildings that are targeted to have sustainable performance. So, the design of the building facades shall be in accordance with the green building standard issued by GBC Indonesia, Greenship NB Version 1.2. The optimization of facade design was conducted based on three parameters: OTTV, daylight, and outside view. The minimum requirements for each parameter are 35 Watts/sqm for maximum OTTV, 30% for a minimum active area covered by daylight, and 75% for a minimum active area with an outside view. One of the aims of this study is to give a depiction of how to conduct a design process by using an iterative way. In addition, it is to identify the critical keys in enabling the building to the requirements.

Green buildings have been gaining in popularity over the past few years in Jordan. This is attributed to environmental and financial reasons directly related to energy consumption and cost. Energy sector in Jordan faces two main challenges which are the fast growing of energy demand and the scarcity of resources to fulfill this demand. Green buildings can save energy by designing them as near Zero Energy Buildings, where they produce amount of energy almost equal the amount of energy they consume. In special cases green buildings can be designed as Net zero energy buildings, where they produce as much energy as they consume. Jordan government encourage people to adopt net zero green buildings by issuing the Renewable Energy and Energy Efficiency Law No. 13 of 2012, that allows selling excessive electricity to electricity companies. Despite these benefits of green buildings, they are not yet the norm in the building sector in Jordan. This can be attributed to the high construction cost of green building compared to traditional one. However, this may not be true if the whole life cycle cost of the building is considered, in which the cost not only include design and construction but also operation and maintenance as well. This paper aims to provide real life cycle cost analysis for a typical residential building in Jordan, and to search different effective building strategies and design scenarios that will lead to a successful near Zero Energy Building. The search will apply main green building strategies recommended for Jordan climatic zone. The outcome of this study is a list of best economically feasible design solutions and system selections that result in near Zero Energy Building in Jordan for residential buildings.

Residential Sector

Existing buildings are the massive percentage of the building stock, and therefore, are the key to improving efficiency; buildings account for an enormous share of the climate change crisis, and approximately 40% of the world total energy consumption (McArthur & Jofeh, 2015). The Egyptian stock of buildings includes about 12 million buildings. 60% of these buildings are residential. The final electricity consumption of the residential buildings in 2010 was 51370 GWh and increased in 2014 to reach 62441 GWh. Thus the share of total energy consumption was 18.8% in 2010 and increased to reach 21.55% in 2014 ("Technology Roadmap - Energy efficient building envelopes.", 2013). Therefore, the residential sector plays an important role in the mitigation of energy consumption crisis, which is expected to increase. The research field and initiatives in Egypt on the green buildings and green buildings retrofits are rare and, if existing, are weakly applied. Unlike in developed countries, there is a large research on building retrofits, e.g., the Residential Property Assessed Clean Energy (R-PACE) program and the weatherization assistance program (WAP) of the department of energy (DOE). Both are examples of the incentives to green building initiatives globally. This paper discusses the challenge of greening the existing residential buildings in Egypt by demonstrating an analysis of the motives and the barriers to applying green measures in the Egyptian market. The research methodology comprises the analytical-comparative method. In the analytical part; the paper identifies the current situation of the residential sector energy consumption in Egypt, and the benefits of greening existing buildings for tenants, investors, and owners. In the comparative part, the current situation of Egypt's Green Market Business Case is compared with the international one, discussing the challenge of greening the residential buildings. The paper summarizes the opportunities to improve the building energy efficiency, incentives, and policies that are developed to address significant financial and technical awareness to building efficiency. These policies will help enable critical market actors to make decisions to promote energy efficiency in existing buildings.

The number of green buildings has increased to address the global environmental crisis. However, green buildings face risks resulting from new materials and methods. In addition, these buildings are expected to perform at higher levels than traditional ones. The objectives of this study are to identify the possible risk factors for architects developing green building projects in South Korea and to assess risk mitigation measures. To attain this goal, fourteen risk factors and twelve mitigation measures were identified from a comprehensive literature review. A questionnaire survey was administered to architects practicing green building design. Findings revealed the ‘adoption of new technology and processes’ was the largest difference between green and traditional building projects. This study identified ‘financial risk,’ ‘design changes,’ and ‘client’s goal uncertainty’ as the top three risk factors in green building design. Additionally, the survey proposed the four most effective risk mitigation measures for green building projects: (1) ‘contract indicating each party’s roles, liabilities and limitations clearly’; (2) ‘utilizing integrated design process’; (3) ‘understanding client’s goal in green building projects’; and (4) ‘improving communication and coordination among stakeholders.’ There are a few studies focusing on the architects’ perceived risk concerning green building projects; however, this study expands the knowledge and fills the literature gap. Additionally, this study provides a comprehensive understanding of critical risks and mitigation measures that can benefit South Korea’s green building design practice through better risk management.

Sustainable practices in the built environment are becoming a more common phenomona as market penetration of green buildings grow. Despite the reported benefits of green buildings, barriers to sustainability still exist. To motivate wider adoption of sustainable built environments, this research studies public policy and its impacts. The study aims to understand the links between public policy, construction playmakers' (e.g., organizations', institutions', business owners', and developers') motivation to build green, and growth of sustainable built environments in the United States. As a step forward in this direction, this paper focuses on the case of Michigan and explores construction playmakers' motivations to build and/or occupy sustainable buildings and how effective current public policy in Michigan is at addressing these motivations. There is little research on the links among legislation, construction playmakers' motivation to build green, and the growth of sustainable built environment in the United States. This article's findings show that: 1) green building costs are still the most frequently-reported barrier to green building, 2) property developers are significantly less likely to utilize green building practices than other construction playmakers, 3) single-family residential buildings were the least likely building type to receive green certifications, and 4) construction playmakers report low levels of green policy awareness and use despite the presence of relevant public policies. These findings will provide direction for policy makers and advocates in creating policy that will effectively promote green building construction.

Nowadays, the concept of green building is no longer an alternative but a necessity. The acceptance of a building as “green” depends on having a certificate. LEED is one of the widely used green building certification systems in Turkey. The main objective of this study is to find out whether there were statistically significant differences between the credit achievements of 105 newly constructed and certified buildings in Turkey, which were certified according to four different levels, and to determine which of these credit achievements are weak. For this purpose, Kruskal-Wallis and Mann-Whitney U tests were performed and the findings were interpreted. Findings revealed that the highest level of achievement of these buildings was in sustainable sites, water efficiency, innovation in design, and regional priority credits, while the lowest level of achievement was in energy and atmosphere, materials and resources, and indoor environmental quality credits. Analyses revealed that the achievements in the energy and atmosphere, materials and resources, and indoor environmental quality credits of green buildings are relatively low when compared to the ones in other credits. There may be several reasons behind these low levels of achievement such as poor green culture, high investment cost of necessary systems, absence of reusable, recycled, and renewable materials. If these problems, most of which are peculiar to developing countries, can be overcome, higher certification levels can be achieved.
