It is becoming increasingly relevant that designs address sustainability requirements. The objectives of any sustainable design are: to reduce resource depletion of energy, water, and raw materials; prevent environmental degradation caused throughout the building lifecycle; provide a safe, comfortable and healthy living environment. Currently, the sustainability of a building is judged by standards codified in a rating system. (1) Although compliance with a sustainability rating system is not mandatory, increasingly, it is becoming a goal that many designers and authorities would like to achieve. However, there are impediments to the pervasive use of sustainable design rating systems. 1. Certification is expensive. ( 2 ) It is labor intensive, involving large volumes of data aggregation, information accounting and exchange, which, can be a deterrent to designers and the design process. 2. Ratings systems are periodically reviewed; as our understanding increase and technology improve, sustainability requirements on designs become more extensive and, sometimes, more stringent. (3) 3. Sustainable building design rating tools are not readily integrated into the design process whereby the design solution can be developed by different disciplines. 4. The design information model associated with a building may not contain the data (attributes) necessary to evaluate its design. 5. Information is disparate and distributed—requiring it to be supplemented, augmented from various sources, and managed for the different stages of a building design process In practice, designers tend to employ commercial (and reasonably stable) design tools, making it imperative to develop an approach that utilizes information readily and currently available in digital form in conjunction with rating system requirements. This research focuses on supporting sustainability assessment where designers need to evaluate the information in a design in order to fulfill sustainability metrics. The main research objective is an approach to integrating sustainability assessment with a design environment. This comprises: identifying informational requirements from rating systems; representing them in computable form; mapping them to information in a commercial design tool; and assessing the performance of a design. An overall framework for organizing, managing and representing sustainability information requirements is developed as the demonstrator. Case study of an actual project demonstrates the flow of information from a commercially available building information modeler and a sustainable building rating system. The process developed bridges sustainability assessment requirements with information from the model for preevaluation prior to submission for certification. Contributions include a technical implementation of sustainable design assessment for pre assessment through a process of identifying information availability, augmentation, representation and management focused on two credits (Reduce indoor water use and Minimum energy performance) over evolving rating standards, namely (LEED 2.1, LEED 2009 and LEED v4). These contributions are intended to enable designers, stakeholders, contractors and other professionals to communicate strategies and make informed decisions to achieve sustainability goals for a project from design through to operation. (1) Design choices are validated, by measuring design performance against criteria specified by the rating system. See Chapter 2: Research Background. (2) “Shame on you for perpetuating this myth that green design costs more even if integrated properly. LEED certification does, but green design need not.” (Kats, 2010) (3) “Sustainability is not static–it is iteratively changing, based on knowledge that connects science and design.” (Williams, 2007)

Leadership in Energy and Environmental Design (LEED) is one of the environmental assessment tools available to gauge buildings. This rating system is a voluntary system which does not include financial aspects in the evaluation framework. This poses a challenge for encouraging land development projects, since developers consider financial or economic return as a crucial factor before building a project. It becomes essential to know if market really accepts the economic worth of LEED ratings. This research attempted to find out relationship between economic worth of a land and parameters (measurements), which are essential to earn LEED sustainable rating for public transportation access. To find out this relationship and to recognize power of the LEED measurements to predict the appraised value of a land (dollars per square foot) various statistical models were used and predictive equations produced. The observational units were properties in Harris County, Texas that were unimproved and had zero improvement value. The dependent variable was unit value of the property measured in dollars per square foot. The independent variables were measurements that are required for a parcel to earn LEED sustainable site rating for public transportation access and the area of parcel. Data regarding appraised values and land area were acquired from the Harris County Appraisal District and transportation data was obtained from Houston- Galveston Area Council. Multiple regression analysis was used to analyze different models and to develop predictive equations. Findings suggest that LEED green building rating system influences the appraised value, dollars per square foot, of properties. It further implies that market considers the economic effect of the LEED rating system even if this assessment method does not explicitly include financial aspects in the evaluation framework. Findings of this research also suggest that a sustainable feature of a site is related to the economic worth of a related land development project. This will provide encouragement for new sustainable land development projects. This will provide an economic incentive to the owners and developers. Developers will get encouragement to select a site located closer to mass transit networks.

Environmental sustainability in regards to infrastructure and the built environment is a significant consideration for the Department of National Defence (DND). As the 2nd largest landowner in Canada, the DND is making great efforts to operate in a sustainable manner through the creation and implementation of sustainable building policies. Meeting the green/sustainable buildings requirements of the recent Federal Sustainable Development Strategy, and the 2006 DND Sustainable Development Strategy to achieve accreditation within generic green building systems, has proven to be extremely challenging given the mandate and the nature of Canadian Forces (CF) operations, both domestically and overseas. This line of research was conducted in order to identify the unique requirements and the sustainability factors/criteria that are applicable to the CF / DND and to investigate how to best align these requirements within the context of sustainable development strategies. Input data was obtained through an analysis of literature and relevant documents, as well as a series of interviews with individuals at all levels within the Federal Government. The result of this research undertaking was, in part, the creation of a Sustainable Development for DND based on a thorough, comprehensive and internationally-investigated factor selection process. These results illustrate the importance for the DND to consider implementing a department-specific sustainable building strategy; one that is more representative of the unique type of infrastructure DND owns and operates. The results of such an investigation can surely be used to assist with best practices and strategic policies within DND and to potentially influence policies at the Federal level of governance in this regard. The ultimate goal of this thesis was to establish the policy framework with a view for DND to develop and implement its own unique Sustainability Standard. / Thesis (Master, Environmental Studies) -- Queen's University, 2012-11-29 14:21:37.63

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2010. / Cataloged from PDF version of thesis. / Includes bibliographical references (p. 88-89). / Preservation of buildings is an important process for both cultural and environmental sustainability. Buildings are frequently demolished and rebuilt long before necessitated by structural or material deterioration, wasting both materials and energy. Preservation can be seen as the ultimate form of recycling; it allows existing buildings to be updated and retrofitted for continued use, optimizing the longevity of the structure while protecting its cultural significance. Currently, there is a lack of motivation and regulation for choosing preservation over new construction. The LEED guidelines give only a small number of points for building reuse, and frequently historic restrictions interfere with measures that would produce the same types of energy savings seen in new construction. This project will use several case studies, including the preservation of Pier A in New York City's Battery Park, as examples of contemporary restoration projects that have received or are anticipating LEED ratings. I will look at these projects in the context of current LEED guidelines and proposed future revisions to investigate how the LEED system addresses issues regarding preservation, and how they could be improved to encourage more sustainable renovation practices. / by Lori Ferriss. / M.Eng.

La conscientisation quant aux enjeux environnementaux n'a cessé de croître au cours des vingt dernières années. Dans le milieu de la construction, comme dans bien d'autres secteurs de nos sociétés, cette conscientisation a donné naissance depuis une dizaine d'années à un foisonnement de programmes volontaires pour les bâtiments. Ainsi, on assiste à l'édification d'un nombre croissant de bâtiments appelés « verts » ou encore « durables ». L'utilisation de ces qualificatifs semble faire l'objet d'une certaine confusion, plusieurs y ayant recours comme s'il s'agissait de synonymes. Le système d'évaluation LEED®, actuellement le programme volontaire en construction le plus influent dans le monde, ajoute à cette confusion conceptuelle dans sa version canadienne. Cette recherche examine le fonctionnement du système d'évaluation LEED Canada NC 1.0 en tant qu'outil de développement durable pour le secteur de la construction. Puisque ce mémoire se penche sur un phénomène relativement récent, nous avons privilégié l'étude de cas pour notre stratégie de recherche en ayant recours à l'observation participante et à l'analyse documentaire pour effectuer la cueillette de données. Comme cadre d'analyse, ce travail se structure autour des principes de construction durable de la norme ISO 15392. Si la littérature semble considérer le système LEED d'abord comme un programme de performance environnementale, notre recherche démontre que ce programme réussit à intégrer en partie les principes du développement durable pour le secteur de la construction. Aussi, les lacunes principales du programme dans le projet étudié se situent dans la faible prise en compte des acteurs touchés par un projet LEED, la transparence déficiente et une évaluation manquante quant aux phases d'utilisation et de fin de vie utile du bâtiment. Toutefois, nous sommes d'avis que le système LEED-NC constitue un outil en constante évolution. En ce sens, il nous apparaît un outil de développement durable en devenir. Il est en effet possible qu'une version du programme puisse, dans un futur proche, intégrer les aspects actuellement négligés du développement durable. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : développement durable, construction, éco-construction, bâtiments verts, bâtiments durables, LEED®.

Commercial office building occupants are a significant consumer of electricity, and they subsequently contribute a significant amount of greenhouse gases into the environment in the process. An opportunity exists to improve the energy efficiency in existing buildings, and the Energy Star certification program provides both tools to do so and an independent verification of a building's superior energy efficiency. However, only 16% of metro Atlanta's office space has achieved this certification. The intent of the research was to identify the current state of energy efficiency in buildings, and to identify potential obstacles to obtaining the Energy Star certification. Towards this goal, secondary research was conducted among prominent academic journals, as well as numerous professional and governmental organizations and publications. Primary research was conducted through an online survey of Facility Managers, Property Managers, and Building Engineers of Energy Star office buildings and comparable non-Energy Star office buildings in the metro Atlanta area. The survey was conducted mostly using closed-ended questions using a Likert scale so as to provide a basis for statistical analysis among responses, and open-ended questions were also included to identify the current state of energy efficiency practices. The research identified three areas which hold statistically significant differences between Energy Star and directly comparable buildings. An analysis also determined that building age does seem to play a role in the building representatives' responses. Four conclusions were found regarding characteristics of Energy Star buildings themselves. The research also identified five conclusions regarding the expected result when pursuing the Energy Star certification. These conclusions include the best method to achieve the Energy Star certification, the expected energy savings, the expected time spent to achieve the certification, the expected cost to achieve the certification, and the main reasons to recertify the building. Finally, this research highlights innovative practices in other states and cities, such as financial incentives and legislation which require commercial buildings to obtain a building rating. Such innovative practices are currently not employed in the Atlanta metro area, but would be beneficial to both the Atlanta area and individual buildings.

Higher education is an idyllically positioned organization from which meaningful dissemination of knowledge and interdisciplinary research is capable of actuating practices that resource consumption. Paradoxically, the construction, maintenance, and operations of the built environment, including the built campus environment, have contributed to the decline of raw resources and degradation of environmental processes. An opportunity exists to bridge the knowledge gap between the design and construction phase and the operations and maintenance phase of the green certified building life cycle, while examining the parts that contributed to the green-certification of the whole building. The purpose of this research was to 1.) identify green-building features and determine their frequency of implementation in new capital (NC) LEED-certified, campus buildings to effectuate operations and maintenance cost savings, indoor wellbeing, and environmental stewardship, and 2.) determine the relationships of greenbuilding feature usage across building, institutional, and LEED characteristics. The study used archival data to document the green efforts of each building with the study’s sample of 195 buildings on the campus of 107 universities and colleges, in the United States, between 2007 and 2017. The study’s findings indicated that the public institutions earned the LEED certification more often than private institutions and the sample was void of two-year community colleges. The sample was restricted for green-building features that (a) reduce economic cost, (b) improve indoor wellbeing, and (c) increase environmental stewardship. The results and implications are discussed. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
