Sustainable Built Environments Senior Capstone Project / LEED, Leadership in Energy & Environmental Design, assists our building industry to become more sustainable. This paper examines three case studies of existing buildings which have evolved to become LEED certified through the rating system of LEED: Operations and Maintenance. Understanding how older generation buildings may still rejuvenate and become sustainable will provide benefits for the people, planet, and profit. As with many things, there are some drawbacks when it comes to LEED certification such as their fees and universal approach for credits acquired.

Sustainable Built Environments Senior Capstone Project / In the United States, commercial rooftops are too often an afterthought, serving only to house HVAC systems and other utilitarian building components. Rooftops are the most underutilized valuable spaces in buildings. They comprise a great deal of real estate that could help boost a building’s energy efficiency, aesthetics, and even the wellness of occupants. Buildings are the leading contributors to energy consumption in the country, and implementing green roofs could significantly mitigate this energy use, so costly to society in so many ways. This proposal studies the benefits of implementing a green roof on the College of Architecture, Planning, and Landscape Architecture (CAPLA) in Tucson, Arizona. Extensive research was conducted on the implementation of a green roof in this hot arid region, as well as a survey among a pool of 50 occupants. The conclusions drawn: a green roof would be utilized by occupants, and would bring about benefits including cleaner air, an expanded roof lifespan, and reduced heat island effect. Conclusions also demonstrate that the cost of implementing a green roof might not be offset by energy savings alone, but when considering the benefits and costs to society, a green roof ultimately proves beneficial economically as well.

Sustainable Built Environments Senior Capstone Project / The southwest region of the United States is stressed for potable water and needs to positively utilize its current water resource. With the urban environment being mostly made up of concrete, it is now crucial to assess its development and application. The concrete used today is a mixture of cement, water and aggregates and is not permeable. The non-permeable property of common concrete prevents natural water absorption by the earth and greatly inhibits water to percolate back into the local water table. As concrete, has developed, porous concrete has been discovered. Porous concrete or pervious pavement is made in the same way that concrete is made with cement, aggregate, and water, but the aggregate used in porous concrete creates pores that allow water to pass through. By allowing water to pass through concrete, urban development will result in greater ground water recharge. As global warming intensifies weather patterns across the planet, Tucson, Arizona will experience heavier rainfall seasons. As the world’s climate changes, Tucson will experience heavier monsoon rain fall events. With heavier rain fall events urban flooding will become more of an issue. Grey infrastructure is needed to manage flooding caused by heavy rain fall. Porous concrete can be used as an effective way to manage storm water. This capstone has undertaken an extensive range of literature reviews to identify where porous concrete can be used for storm water harvesting. The literature reviews range from climate change to the benefits of storm water harvesting. Porous concrete allows storm water to infiltrate through it and back into the local aquifer and directs storm water into retention ponds for treatment and reuse. Porous concrete is a low impact development (LID) building material, which will turn urban development into Sustainable development. Porous concrete if used correctly for storm water harvesting can reduce potable water stress, reduce pollutants found in local waters, and reduce the strain on current storm drains. The required maintenance associated with porous concrete is minimal and not costly, therefore will be only briefly explained throughout this research. While porous concrete has a wide range of benefits ranging from water percolation to the reduction of the heat island effect, this paper will focus on its use as a means of storm water harvesting.

This narrative is retrospective and reflective as well as projective. The thesis of a PhD by publication does not inherently align with a principal proposition. The building, books, chapters and articles collected in this PhD have been shaped by interaction with varied professional, academic and cultural environments and milieus. Professional contexts that have triggered research questions and enriched research methodologies range from architectural practice to scholarly research and collaborative field research undertaken internationally; cultural milieus include Germany, Switzerland, the UK, and, recently, countries of the Global South. The work was not produced with a singular destination in sight; rather, it proceeds along a set of distinct, but interdependent vectors, through changes in direction, displaced vantage points, and transposition between corporeal, architectural and urban scales. This narrative juxtaposes, confronts and discusses the work collected in the portfolio, but does not seek to unify through imposing a singular thesis. The portfolio comprises of a building project, introductory essays to three edited books, three book chapters and nine journal articles, designed and built, written and published over a period of eighteen years from 1998 to 2016. The narrative reconstructs successive questions about diagrams that led to the building project, books, and articles, and the contexts which prompted the questions and frame the work. Rather than aligned to a linear narration, the work is presented along four parallel but interrelated paths of enquiry (Sections A, B, C, D) in which one output led to another, sometimes directly, at other times over detours and longer intervals. The work is introduced through four themes that cut across those paths. While framing and consolidating a retrospective view, the narrative of this PhD also exposes previously unrecognized resonances. New meaning arises from juxtaposition, grouping, contextualising and ordering of outputs and trajectories. In this sense, the retrospective view becomes prospective and projective.

This thesis describes the methods by which individuals and associations give meaning to the concept of profession within the English building industry in the late modern period. The hypothesis is that professional associations control occupations. Whilst this might be accepted in a wider literature, building professionals identify with a far bleaker, late modern, interpretation of profession. The literature portrays a 'backwards' industry without a determinant authority, characterised by fragmented and servile professional associations. The thesis utilises Burrage's (2006) four-goal-framework to structure its investigation through semi-structured interviews with professionals and their associations. This proposes that associations control admission and training, define and defend a jurisdiction, set up a system to govern their own members and seek to improve their corporate status. This work concludes that professionals and associations strategically engage with these issues. There are problems facing professions, but their demise is not one of them. Indeed, rather than be defensive, associations are enhancing their controlling systems. This involves a looser coupling between associations and their membership, which creates some fracturing to the construction of identity. However, the result is new forms of occupational provision, in alliance with both clients and the state, that establish clear dialogues for identity and very specific types of service that are well separated from external 'quacks'. Faced with an environment that is ostensibly deeply sceptical, associations are selective in how they defend and enhance both their status and control systems. This has led, for example, to a withdrawal from controlling entry in the face of government demands to widen participation, to be replaced with strong regulatory schemes for members. This creates standardisation and practical guarantees of competency, a powerful executive in a quasi-judicial regulatory role, and clear rules of behaviour and permanent training through CPD. The result is 'competent', 'safe', 'good' and 'ethical' occupational jurisdiction.

The aim of this research is to contribute to the concept of authenticity for the conservation of historic places. The focus of this work is a development of a set of criteria to assess authenticity in order to contribute towards the conservation of historic places in Western Europe.The purpose is to define a set of authenticity criteria. Firstly, this thesis describes the concern of the concept of authenticity in conservation of the built environment and, based on a review of relevant research and theories on how authenticity criteria fit in conservation in general and how it is important to define a set of authenticity criteria in order to conserve historic places in Western Europe. Based on this review of relevant research and theories, the researcher understood the need to define a set of authenticity criteria in order to facilitate the conservation of historic places in Western Europe. The set of criteria to assess authenticity in the conservation of historic places is based on the spirit of UNESCO criteria to test authenticity with the definitions of the criteria used by the USA Parks Service to evaluate integrity of the property in order to be listed. The initial set of criteria is composed of seven qualities as follows: Location, Settings, Design, Workmanship, Materials, Feelings and Association. Linked to the "state of the art " of Conservation of Historic Places in Western Europe, these criteria were applied to four case studies that showed the evidence in all of them, but strongly demonstrates that Location, Feelings and Association are not important criteria for Western Europe. However Function / Use is an important criteria for all Europe. According to the case studies' conclusions and the review of literature, the model of research created is based on five parameters which define the qualities to assess authenticity in conservation. Four of these parameters (Design, Materials, Workmanship and Settings) are based on USA Parks Service definitions.The fifth parameter (Function / Use) is based on the case studies' conclusions. With the support of a sounding board of experts, the author developed a conceptual model for checking the propositions. This model and the propositions were checked by the Delphi Process with a further group of twenty experts from Western Europe and through a continuous analysis of the data. The set of authenticity criteria established was sent to the Delphi panel of experts in Portugal, the UK and West European organisations involved in the conservation of the built heritage with statements in order to find an agreement on the evidence and definition of each criterion. This procedure was based on the assumption that the achievement of a consensus was possible. Consensus was, in fact, obtained about the criteria. The final criteria achieved highlight the emerging importance of function and use in historic places for the future. The final criteria are: Material Design Workmanship Function/Use Setting DEFINITIONS The physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form an historic property. Combination of elements that create the form, plan, space, structure, and style of a property. The physical evidence of the crafts of a particular culture or people during any given period in history or prehistory. The degree of continuity of original or significant uses in a property. The physical environment of a historic property. Due to the fact that the sounding board of experts and Delphi members were made up of people with different backgrounds, ranging from Academia, Architecture, Construction, Industry of Culture, NGOs (Non Governamental Organizations) and other built heritage organizations (UNESCO, ICCROM, ICOMOS, Europa Nostra and Council of Europe) the final set of criteria to assess authenticity for conservation of historic places in Western Europe has an holistic point of view.
