Eco-friendly & sustainable solutions for conflict affected areas: A case from red corridor region

Contemporary designs have been tried and tested for a part of India where they outreached through development firms, but it does not/or it’s difficult to make such designs acceptable in areas that are conflict prone and require certain essential interventions. This paper provides alternative solution for building architectural design, selection of materials and suitable construction methods for buildings which are required in running of soft programmes by government agencies in areas that are affected by left wing extremism. In these regions the government has been trying to focus on soft programs like education, health, hygiene, nutrition, and civil supplies. In such regions it becomes difficult to establish concrete buildings and structures for the government, due to unrest prevailing in these areas, one of the reasons for this is that these regions are rich in forest cover and mineral deposits. Therefore, it becomes necessary to provide sustainable solutions with actual understanding of ground realities prevailing in these remote areas which can help to fulfil the purpose of welfare schemes. Through this paper eco-friendly and sustainable solutions for existing infrastructure required for soft programs in Narayanpur district of Chhattisgarh affected by Left Wing extremism have been explored using parameters given in LEED green building rating system. To observe prevailing ground realities ethnographic observations have been used as a methodology to express the importance of meeting the consumer needs in less resource intensive ways. These sustainable solutions could be used by stakeholders to reach out to the similar communities and help in enhancing the integrated approach adopted by the government.

Performance gaps of sustainability features in green award-winning university buildings

Sustainability certifications like BREEAM, LEED, and China's sustainable green building award certification scheme encourage installation of technologies that save mains water and grid electricity. Among these are rainwater harvesting systems, ultralow water use appliances, photovoltaic panel systems, and intelligent building management systems. In reviewing the performance of two award-winning university buildings over respective periods of sixteen and four years, we found that such systems delivered only 28–71% of their potential resource savings. These performance gaps arose from various technical and social issues (pump failures, tank leakages, poor alignment of demand and supply with limited storage, low photovoltaic panel efficiency, poor user acceptance, etc.), but the consequences were exacerbated by inadequate asset management that resulted in long system downtimes, in some cases for 2–5 years. Repair, maintenance, and upgrading expenses then combined with lower than anticipated water and electricity bill savings that ultimately meant that, for the most part, there was no prospect of earning a return on capital expenditures. Continuous monitoring of building water consumption by an external service provider was the most effective resource and cost saving solution in this study, as it required no capital expenditure, and revealed a 1640 l/h leakage, without putting high demands on the building management. In contrast, little value was obtained from 25 water-related sensors installed as part of a “building-as-a-lab” project because of inadequate post hand-over support. Robust post-commissioning operation should become a key criterion for sustainable building innovation, and this should be reflected in green awards and rating systems.

Using the new ASHRAE 189.1 Standard for the Design of High-Performance Green Buildings—Acoustical Control Section

The 2017 ASHRAE 189.1 Standard for the Design of High-Performance Green Buildings includes a complete rewrite of the acoustical control section. This section of the standard provides both performance and prescriptive paths to acoustical compliance and permits either acoustic commissioning or visual inspections to ensure the materials and assemblies are built to optimize acoustical performance. We will outline the importance of this new standard and review the basic parameters of the acoustical performance requirements, and how this standard can be used for your projects. This session will discuss the basis for this updated section and how you can use this standard to help guide your clients, and satisfy the LEED v4 for BD + C. The 189.1/IgCC aligns well with LEED, WELL, and other green building and improves on the LEED certification standard, so basic compliance will often garner the acoustic performance points.The 2017 ASHRAE 189.1 Standard for the Design of High-Performance Green Buildings includes a complete rewrite of the acoustical control section.

COMPARISON OF BUILDINGS IN ANCIENT TIMES WITH MODERN GREEN BUILDING PRACTICES

Since the focus on sustainable development in 1980s, there has been an increased awareness for well-defined green building standards worldwide. Before the advent of much of the modern green construction standards and practices, ancient European buildings had implemented many features that would be considered green today. Ancient European construction used vernacular architectural, which incorporated climate responsive designs and solar architecture. In some instances, ancient building practices have been used to improve modern building materials, such as brick and concrete. These aspects of green buildings in ancient Europe can provide ample opportunity for research today. The goal of this paper is to analyze building designs, materials, and methods used in ancient Europe and compare these practices to current green building guidelines. The scope of this paper includes examining preexisting literature on building practices in Europe before 1800AD and analyzing two case study buildings in light of LEED green building guidelines. Finally, a comparison matrix of green building features, in ancient European buildings and in modern LEED buildings, is developed. It is hoped that such comparison will provide an insight into the relevance of ancient building attributes in modern green building practices.

Properties of Pervious Concrete Aiming for LEED Green Building Rating System Credits

Pervious concrete is a special type of concrete with high porosity. The use of pervious concrete may achieve many potential LEED green building rating system credits. The objective of this paper is to investigate the appropriate mix proportion which provides the high LEED points and also the good mechanical properties. Nine mix proportions based on possible LEED points were examined. The replacement of cement by fly ash (20% - 60%) and coarse aggregate by recycled aggregate (20% - 100%) were used. Properties of pervious concrete relating to LEED credits and design values such as permeability, void content, compressive strength and splitting tensile strength were evaluated. It was found that the proposed pervious concrete can achieve the stormwater design-quantity control, recycled content and recycled materials credits. According to the results, the mix proportions which cement was replaced by 40% and 60% of fly ash archived the highest LEED credit points and also provided the sufficient mechanical properties. Therefore, these mix proportions are recommended for green construction.

Improving Occupant’s Satisfaction and Productivity in Sustainable Building Design

Indoor environmental quality in green buildings is generally assumed as superior to conventional buildings.The reason of this assumption stems from prerequisites in indoor enviromental quality credits in LEED, BREEAM and other green building certificates.But there is a need for a look from the viewpoint of green building occupants. Quality in lighting, air, acoustics,thermal environment and other environmental aspects must be in accordance with competences for green building certification,furthermore they must be in accordance with occupant expectations. Green buildings must provide a productive workplace for it’s occupants but it’s not possible without occupants satisfaction and comfort. This paper presents the findings of the literature research about occupant satisfaction,health and productivity in green buildings-particularly in offices and the survey results which is administered in a LEED EBOM certified office building in Istanbul. Two questionnaires are carried out within the context of the study; one is before and the other is after the building gets the LEED certification. The study shows that having a LEED certificate doesn’t guarantee the maximum employee satisfaction Analysis of the research findings indicate that, green buildings must be designed ,renovated and operated considering not only energy and material regulations but also indoor environmental issues that the occupants could face.

Applicability and Implementation of U.S. Green Building Council Rating System (LEED) in Egypt (A Longitudinal study for Egyptian LEED Certified Buildings)

According to the USGBC projects’ directory, there are only Six LEED Certified projects and 17 registered projects in Egypt. This implies the limited number of LEED projects in Egypt. That's why most of the empirical studies conducted about LEED Rating System were performed on other markets than the Egyptian one; Accordingly This paper is the result of a longitudinal study that was performed on Three Egyptian LEED Certified projects as a part of a master thesis research that was submitted to Cairo University in 2013 by the first author where the second and the third author were the main supervisors. The objective of this study was to investigate the implementation of the LEED Rating system credits in Egypt through a comparative analysis of Three Egyptian LEED Certified projects.The results of this study included a classification for the most achieved and targeted credits within the Egyptian market. This study may also contribute to a better understanding of the concept of implementing LEED green building rating system in Egypt and may suggest some recommendations for future studies.

설계초기단계에 적용 가능한 초고층건축물의 패시브디자인 계획요소에 관한 연구

High-rise buildings may have problems of negative effects on the environment through excessive energy consumption and CO2 emission. Therefore, the purpose of this study is to establish the passive design elements that can be applied in the initial architectural design phase and to analyze them through some specific high-rise building examples that had acquired LEED green building certification. The findings of this study are as follows; The cooling and lighting are major factors for energy consumption for high-rise buildings. The major factors for reducing the energy consumption in the early design stage are Daylight, Solar heat, Curtain wall facade design, and Solar shades in terms of solar radiation, and Renewable Solar energy, Design for wind load, Natural Ventilation, and Renewable wind energy in terms of air flow. It is necessary to select appropriate strategies for the passive design according to divers climate characteristics. From the twelve buildings of green building certification, applications of passive design method are characterized according to the climatic zones, mass orientations, floor plans, forms and facade design elements.

Examining Contemporary Issues for Green Buildings from Contractors’ Perspectives

Sustainable planning and design is a mass movement for changes in the construction industry. Among many other green building rating systems, the USGBC's LEED has been gaining momentum throughout the years since its advent. With sustainable design and construction, people could live in a more environmentally friendly world which would ensure that our future generations to come would have the necessary resources to live their lives comfortably and thrive. To implement the LEED process, construction contractors need to modify and enhance the way they have historically planned and executed design and construction work. With the rising change in the way a building is built to satisfy the LEED green building intents and requirements, there comes added fears and negative perceptions due to the lack of knowledge from the contractors’ perspectives. Thus, this paper presents a comprehensive analysis of 40 surveys collected from the contractors with previous experience in green building projects. The main issues include increased time demand, fear of change, increased equipment costs, fear of auditing of construction documents and many more. By examining the main issues contractors revealed with the green building delivery method, this study will serve as a platform in which future researchers may continue and expand on the issues and/or concerns in order to make the green building delivery method more acceptable to the general contractors and subcontractors.

Predicting Appraised Value of Parcels of Harris County, Texas Using LEED Criteria for Public Transportation Access

The objective of this study is to determine if the appraised unit value ($/sf) of unimproved land parcels in Houston, Texas could be predicted by a regression equation containing a group of independent variables that represent LEED transportation access criteria and the area of a land parcel. The independent variables, number of bus stops, number of rail stops and parcel area, were all found to contribute significantly to the independent variable, appraised unit value of a parcel. The observational unit was properties in Houston, Texas that were unimproved (had zero improvement value). Findings suggest that the acceptance criteria for the LEED green building rating system regarding public transportation access have a significant influence on the appraised value in dollars per square foot of the subject properties. Based on the sample median lot size of 5,300 square feet, the predicted lot value increases dramatically in proportion to the number of qualifying light rail stations and decreases marginally in proportion to the number of qualifying bus stops. Since the regression model and each independent variable were all significant at p<0.05 and the adjusted R-square was near 0.50, the study objective was deemed to have been answered in the affirmative.

The Importance of the Appearance Image and Cognition of Green Building

When global climate change becoming a problem that is getting worse nowadays, Green Buildings have become one of the major solutions to maintaining a sustainable environment. Because most of the public interpret the messages sent by their environment through visual appearance and images, This study aims to analyze the appearance effects of U.S. LEED and Taiwan EEWH Green Building rating systems by conducting surveys on the publics cognition of green building appearances and green building rating systems, and analyzing the relationship between green building appearance and environmental cognition. The results indicate that building appearance is a key judgment reference for identifying green buildings. However, there has been no significant relationships found between green building rating system and green building appearances so far, which may cause confusion as to the publics cognition and image of green buildings. Therefore, it is recommended that building's appearance image should be included in future revisions of the green building rating systems.

미국 내 LEED 그린빌딩의 지속가능한 업무공간 사례 연구 - 실내 평가요소 중 재료 및 자원을 중심으로 -

(Background)In modern industrial society, the design industry failed to observe the law of nature, destructing it. Regardless its intention, the design industry destructed the environment so that it can't maintain the future life because of waste and disaster. For the purpose, it is important to adopt the technology to reuse the waste resource generated by building or minimize the damage to environment for the resource that can't be recycled. (Methods)On the assumption that the material and resource can be an alternative plan for the design that can make environment be sustained, the study analyzed materials and resources out of superior office space of USA, which were selected by LEED Green Building Rating System. (Results)The analysis result revealed that all cases reused main structural part of existing building and indoor and various materials were reused or recycled. Especially, the materials without or with low amount of VOCs and formaldehyde were used. In order to reduce construction waste, the finish of existing building was exposed as it was, 50% of reused materials were used or disassemblable materials were used. When regional materials are used, there is an advantage to reduce transportation cost and recycle the materials rapidly. Lastly, the environment-friendly certified by FSC was used in all cases. (Conclusion)After all, the material is one of the space design strategies sensitive to environment so it is important to select good material. Harmless, environment-friendly materials applied to sustainable office space contribute to the creation of healthy environment. In addition, the use of recycled materials and reused materials to minimize waste is also essential factor for creating sustainable space.
