The energy consumption of residential buildings in Canada accounts for 17% of national energy use (Trudeau, 2005). Production homes represent a considerable portion of new housing. In an effort to reduce the national energy demand, the energy consumption of these homes must be addressed. Techniques, methods and materials to achieve reductions in residential energy use are readily available. The goal of this thesis is to show that it is possible to build a low-energy home for less total carrying cost than a home built to the 2006 Ontario Building Code. To show how this is possible, a range of cost-effective and practical-to-implement upgrades are identified, and quantitative projections of cost-savings and benefits gained by the homeowner are generated. The interest in, and demand for, greener less energy consumptive homes is increasing. As oil prices rise, climate changes, landfills become overburdened and water restrictions become more frequent, the public pushes harder for change. The residential housing sector has seen increased demand for energy efficient homes that incorporate green features, high efficiency appliances and mechanical systems. Increased environmental concern has put ‘Green’ in demand. This thesis reviews a variety of North American green rating systems and contrasts their energy performance requirements with those of the Ontario Building Code. The Ontario Building Code was considered the baseline. Although the R2000 program was originally developed nearly 30 years ago it has managed to maintain a standard of performance that has always exceeded the OBC. It has a wider range of requirements than either the building code or ENERGY STAR, but falls short of the LEED for homes program in terms of breadth of environmental concerns. The literature review shows that homes that use 75% less heating energy than a standard house could be built in the 1980s for a mere 5% construction cost premium. When care is taken to produce quality designs and specifications, and to ensure that details are properly finished, these types of homes can be built almost anywhere. Some of the most successful technology and strategies of the 80’s have found their way into mainstream Canadian houses. As a result, the average new Canadian home consumes less energy than its predecessors. The Ontario building code has some of the most stringent thermal insulation and energy performance requirements of all provincial codes in Canada. However, significantly more can be done to economically reduce house energy consumption. A parametric analysis of a representative urban house was performed. This analysis suggests that there is significant room for improvement in the minimum Ontario Building Code requirements, especially with regard to the insulation and air tightness specifications. In 2006 the OBC requirements for above grade wall insulation were increased from R17 to R19 whereas this investigation found that R34 could be justified financially. The fenestration requirements in the 2006 OBC require windows to attain at least R2.8, while this investigation shows that a further 25% increase to R3.5 will soon be financially sensible.

Three illustrative cases involving the electrodeposition of ultrathin metal films of varying reactivities onto noble-metal substrates were investigated: (i) Pd on Pt(111), a noble admetal on a noble-metal surface; (ii) Bi on Pd(111), a less noble admetal on a noble-metal surface; and (iii) Co on polycrystalline Pd and Pd(111), a reactive metal on a noble-metal surface. The interfacial electrochemistry of these prototypical systems was characterized using a combination of electrochemical methods (voltammetry and coulometry) and ultrahigh vacuum electron spectroscopies (Auger electron spectroscopy, AES; low energy electron diffraction, LEED; and X-ray photoelectron spectroscopy, XPS). Potential-controlled adsorption-desorption cycles of aqueous bromide exerted surface smoothening effects on ultrathin Pd films with defect sites (steps). This procedure, dubbed as electrochemical (EC) annealing, constituted a nonthermal analogue to conventional annealing. EC-annealed ultrathin Pd films exhibited long-range surface order and remained free of oxygen adspecies. Pdadatoms occupying step-sites were selectively dissolved and/or rearranged to assume equilibrium positions in a well-ordered (1x1) film. Electrodeposition of Co was found to be highly surface-structuresensitive. While virtually no Co electrodeposition transpired on a clean Pd(111) surface, Co was voltammetrically deposited on (i) a Pd(111) electrode roughened by oxidation-reduction cycles; and (ii) thermally annealed polycrystalline Pd, which is a composite of the (111) and (100) facets. Electrodeposition of Co was also observed to be kinetically hindered and slow potential scan rates (0.1 mV/s) were required. Well-defined ultrathin Bi films were potentiostatically electrodeposited onto Pd(111); a Stranski-Krastanov growth mode was indicated. The electrochemical reactivity of ultrathin Bi films was characterized using two surface probes: aqueous iodide and D-glucose. (i) Exposure of the prepared Bi adlayers (ΘBi 0.33) to aqueous iodide gave rise to (√3x√7) I-on-Bi superlattice. The same superlattice was obtained if Bi was electrodeposited onto Pd(111)(√3x√3)R30o-I. (ii) With respect to electrooxidation of D-glucose on Pd(111), the presence of Bi adlayers inhibited the by-product-induced "surface poisoning" of Pd(111) but reduced its electrocatalytic efficiency.

Sustainability is quickly becoming a “buzz word” in today’s environmentally conscious world from political leaders to building professionals to design experts to consumers as they rethink their impact on current healthy, efficient indoor/outdoor environments as well as long term benefits to future generations.This paper seeks to investigate ways to increase the structural engineer’s influence over the sustainability of the building industry by using integrated design teams. It explores current practices within the building industry, in particular the housing industry and the ways in which the integrated design team differs from most current practices. It strives to promote the positive impact an integrated design team with structural engineers on board from the onset has on the design process as far as time, cost, and environmental concerns are considered. This paper continues by establishing methods for measuring the success of an integrated design team,its effects on sustainability, and how the structural engineer was involved.The focus of this paper is the New Norris House class project: its background and the integrated design team’s process as it differs from the traditional design concept. The results of the project including the LEED and HERS rating and material efficiency and the impact of the structural engineer’s inputs from the onset will be discussed. The paper ends with a discussion on the differences between the educational and professional community and how integrated design teams are an efficient and cost effective way to achieve high levels of sustainability.

Aus der riesigen Vielfalt organischer Materialien sind gerade die Phthalocyanine dafür bekannt geworden, auf verschiedenen kristallinen Substraten geordnete Strukturen auszubilden. Außerdem dienen diese Moleküle als Modellsysteme für grundlegende Untersuchungen zur Einstellung elektronischer und struktureller Eigenschaften durch gezielten Einbau eines Metallatoms in den zentralen Hohlraum. Die Strukturen der Adsorptionsschichten von verschiedenen Metallphthalocyaninen, funktionalisierten Phthalocyaninen und Naphthalocyaninen auf der Basaldebene des Graphits werden verglichen, um die Adsorptionsstruktur der einzelnen Moleküle innerhalb der Adsorptionsschicht zu verstehen. Das erlaubt uns die Untersuchung der Molekül-Molekül- und Molekül-Substrat-Wechselwirkungen in Abhängigkeit von Molekularadsorption des zentralen Metallatoms, der Geometrie, einzelner funktionellen Gruppen oder ähnlichem am Molekül. Der Vergleich der Adsorptionsstrukturen von Phthalocyaninen wie PdPc und PtPc, welche d8-Metalle enthalten, dient dem Verständnis für den Effekt des Metallatoms, speziell bei großen Ordnungszahlen. Während beide Moleküle ähnliche Arten von Adsorptionsstrukturen ausbilden weist die PtPc-Adsorptionsschicht eine außergewöhnlich hohe thermische Stabilität auf. Das wurde auf die stark Molekül-Molekül-Wechselwirkung zurückgeführt, die durch die Metallatome in der Adsorptionsschicht vermittelt wird. Der Effekt langer molekularer ‚Flügel’ wird durch den Vergleich der Adsorptionsstrukturen ebener Naphthalocyanine mit denen von ebenen Metallphthalocyaninen demonstriert. Naphthalocyanine bilden viel lockerer gepackte Adsorptionsschichten als Phthalocyanine, was von der stärkeren sterischen Abstoßung zwischen den Wasserstoffatomen in benachbarten molekularen ‚Flügeln’ herrührt. Cyano-funktionalisierte metallfreie Phthalocyanine zeigen als Adsorptionsschicht eine poröse Netzwerkstruktur. Es konnte gezeigt werden, dass durch die Sondenspitze hervorgerufene Störungen dieser Struktur durch die elektrostatische Wechselwirkung zwischen den Molekülen in der Adsorptionsschicht bald weider ausheilen. Schließlich ist durch den Vergleich von Adsorptionsstrukturen ebener Naphthalocyanine und nichtebener Zinn-Naphthalocyanine auch der Geometrieeffekt untersucht worden. Abweichend von allen anderen untersuchten ebenen Molekülen haben Zinn-Naphthalocyanine eine Adsorptionstruktur, die der des Graphits ähnlich ist (hexagonal). Deshalb überwiegt in diesem Fall die Wechselwirkung zwischen Molekül und Substrat, und die Adsorptionsstruktur folgt der Geometrie des Graphitsubstates. Darüberhinaus sind mit der Tunnelspektroskopie in Abhängigkeit vom Abstand zwischen der Spitze und der Probe die elektronischen Eigenschaften der Molekül-Substrat-Grenzfläche für Naphthalocyanin und Zinn-Naphthalocyanin untersucht worden.

The U.S. Green Building Council (USGBC) is the developer of the Leadership in Energy and Environmental Design (LEED™) green building scoring system. On first inspection of LEED points, few address water efficiency. However, water management encompasses other points beyond the Water Efficiency (WE) category. In general, the industry is apt to take a somewhat compartmentalized approach to water management. The use of alternative water sources or the reuse of wastewater significantly complicates the water budget picture. A total water management systems approach, taking into consideration water from various sources, both inside and outside the building, should be implemented in order to devise a strategy for optimal reduction of potable water consumption and wastewater generation. Using the STELLA software to create an integrated building water management (IBWM) model provides stakeholders with a tool to evaluate potential water savings under dynamic conditions for a specific project site. Data collection for IBWM model calibration also shows that water consumption trends are unique to each project, and using LEED assumptions about water usage can overestimate or underestimate potential water savings.

The growing sustainable design movement in the United States focuses almost exclusively on the construction of new buildings, largely ignoring the existing and historic building stock that constitutes the majority of our built environment. Historic preservation, a discipline that deals exclusively with the existing building stock and puts an emphasis on long-term management of the built environment, would seem to be an ideal partner for the sustainable design movement as it begins to address existing buildings. The practice and goals of the two fields, however, are currently perceived to be in opposition to one another by the building community and the general public. This thesis argues that sustainable design and historic preservation represent two unique and distinctive building subcultures – distinct subsets of the larger building culture of which they are a part, and that the opposition between the two disciplines stems from not only their historically distinct discourses, but also from cultural and ideological conflicts between the two fields. Different languages, code typologies, cultural identities, and conflicting attitudes toward the use of technology in contemporary building practice all stand as barriers to a significant partnership between the two disciplines. This thesis explores the cultures of sustainable design and of historic preservation in order to provide a view for practitioners in both fields into the culture of the other, and ultimately proposes a path towards developing shared cultural understandings by placing a new emphasis in both fields on social sustainability. / text

Green buildings are increasingly in demand yet current green building practices often do not consider hazard mitigation. High-performance buildings that can withstand hazards, protect residents, and do not need to be rebuilt following a disaster are truly sustainable buildings. This report focuses on current hazard mitigation and disaster resilience standards for wildfires and earthquakes through an in-depth analysis of case studies and best practices for these hazards. The U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) framework is the ideal vehicle to incorporate hazard mitigation methods into official green building certification. Language for a new LEED Hazard Mitigation and Resilience credit area is established using guidelines for hazard mitigation for wildfires and earthquakes. / text

In drylands, it is essential to maximize the coupling of social and ecological systems in order to achieve sustainability, particularly in human dominated landscapes such as cities. The enhanced use of greenspace in cities in drylands provides unique opportunities to maximize the coupling of social and ecological systems. It maintains the functioning of ecological systems while involving civil society in the conservation of biodiversity and improving human wellbeing in urban settings. The provision and access to greenspace in cities is determined by neighborhood design. The access for the human use of greenspace can be enhanced through walkability, or the characteristics of the built environment that influence physical activity. Walkable neighborhoods that provide access to greenspace can be catalysts for activity and health and have the potential to increase the level of conservation support in urban residents. The purpose of this research is to look for wellbeing and conservation synergies between walkable neighborhoods and the enhanced use of greenspace. To accomplish this research, first we assess walkability in the built environment through an interdisciplinary literature review that integrates the findings on walkability from several research domains. We create a conceptual framework that organizes the neighborhood design elements that influence physical activity into nine walkability categories: connectivity, land-use, density, traffic safety, surveillance, parking, experience, greenspace, and community. We call this the Walkability Framework. This analysis allows us to identify gaps and strengths of walkability in the Leadership for Energy and Environmental Design for Neighborhood Development (LEED-ND) certification system. After a quantitative and qualitative analysis, we propose an enhanced version for walkability that we call LEED-NDW+ (walkability plus). The next step is to test if the Walkability Framework can be used as a model to measure the interactions between the built environment and physical activity. We accomplish this through the use of a questionnaire (N=486) that captures the perceptions, attitudes and behaviors of residents in Tucson, Arizona. Significant correlations between all the walkability categories and physical activity support the use of the framework as a model. We call this the Walkability Model. The final stage of this research uses the Walkability Model to evaluate walkability in four neighborhood design types in Tucson that include traditional development, suburban development, enclosed community, and cluster housing. We then look for wellbeing and conservation synergies between walkable neighborhoods and the enhanced use of greenspace. Results from this study suggest that neighborhoods with a high level of walkability have the potential to enhance the use of greenspace, which in turn provide important wellbeing and conservation synergies that can contribute to healthier communities and increase the support for conservation of biodiversity within and beyond cities. The enhanced use of greenspace maximizes the coupling of social and ecological systems in cities in drylands, which increases resilience in the face of climate change.

Redan 2008 satte EU upp klimatmål om att minska utsläppen och spara energi. Minska utsläppen av växthusgaser med 20 procent jämfört med 1990. Den totala energiförbrukningen ska minska med 20 procent jämfört med denprognostiserade trenden. 20 procent av den totala energiförbrukningen ska komma från förnyelsebara energikällor. Genom att då tillämpa en miljöcertifiering på byggnader är detta ett steg på vägen för att uppnå desatta målen. Med miljöcertifiering menas att byggnaden betygsätts med hänsyn till uppnåddmiljöpåverkan utifrån en tredjepartsgranskning. Utifrån ett certifieringssystem får en byggnad ettcertifikat som visar dess miljöprestanda.Det här examensarbetet har som syfte att ta fram ett förslag på miljöcertifieringssystem åtByggbolaget i Värmland med riktlinjer att det skall vara så enkelt och kostnadseffektivt sommöjligt, för att sedan tillämpa detta på Etapp 3 på Bryggudden i Karlstad. Detta med anledning avatt Byggbolaget i Värmland ser ett ökat behov på marknaden utav dessa kunskaper. Decertifieringssystem som ingår i urvalet är, EU GreenBuilding, Leed, Miljöbyggnad och Breeam SE.Utifrån litteraturstudien kunde slutsatsen dras att det certifieringssystem som var lämpligast atttillämpa på Etapp 3 på Bryggudden i Karlstad var Miljöbyggnad. Detta val grundade sig på attByggbolaget i Värmland efterfrågade ett enkelt och kostnadseffektivt miljöcertifieringssystem medrelevanta miljövärderingar. Den största svårigheten med att tillämpa Miljöbyggnad på Etapp 3 varatt byggnaden redan var färdigprojekterad när certifieringsprocessen inleddes, vilket begränsademöjligheten att styra teknik och systemval. En miljöcertifiering enligt Miljöbyggnad på Etapp 3skulle leda till byggnadsbetyget silver. / Back in 2008, the EU set climate targets to reduce emissions and save energy. Reduce greenhouse gas emissions by 20 percent compared to 1990. The total energy consumption will be reduced by 20 percent compared to the forecasted trend. 20 percent of the total energy consumption from renewable energy sources. By applying environmental certification of buildings, this is a step to achieve the set targets. Environmental certification means that the building is graded with respect to the achieved environmental impact based on a third-party review. Based on a certification, a building certification shows its environmental performance.This degree project aims to produce a proposal of environmental certification for Byggbolaget i Värmland based on the guidelines that it should be as simple and cost effective as possible, and then apply it to Etapp 3 on Bryggudden in Karlstad. This is to the fact that Byggbolaget i Värmland sees a growing need for these skills in the market. The certifications included in the sample is, EU GreenBuilding, the LEED, the Miljöbyggnad and the BREEAM SE.Based on the literature review it could be concluded that the certification appropriate to apply to Etapp 3 on Bryggudden in Karlstad was Miljöbyggnad. This choice was based on the request of Byggbolaget i Värmland of a simple and cost-effective environmental certification with the relevant environmental values. The main difficulty in applying the Miljöbyggnad on Etapp 3 was that the building was already fully planned when certification process began, which limited the ability to control technology and system selections. Environmental certification according to Miljöbyggnad on Etapp 3 would lead to construction grade silver.
