global scenarios of urban density and its impacts on building energy use through 2050
Proceedings of the National Academy of Sciences of the United States of America, 2017Co-Authors: Burak Guneralp, Yuyu Zhou, Diana Urgevorsatz, Mukesh K GuptaAbstract:Although the scale of impending urbanization is well-acknowledged, we have a limited understanding of how urban forms will change and what their impact will be on building energy use. Using both top-down and bottom-up approaches and scenarios, we examine building energy use for heating and cooling. Globally, the energy use for heating and cooling by the middle of the century will be between 45 and 59 exajoules per year (corresponding to an increase of 7–40% since 2010). Most of this variability is due to the uncertainty in future urban densities of rapidly growing cities in Asia and particularly China. Dense urban development leads to less urban energy use overall. Waiting to retrofit the Existing Built Environment until markets are ready in about 5 years to widely deploy the most advanced renovation technologies leads to more savings in building energy use. Potential for savings in energy use is greatest in China when coupled with efficiency gains. Advanced efficiency makes the least difference compared with the business-as-usual scenario in South Asia and Sub-Saharan Africa but significantly contributes to energy savings in North America and Europe. Systemic efforts that focus on both urban form, of which urban density is an indicator, and energy-efficient technologies, but that also account for potential co-benefits and trade-offs with human well-being can contribute to both local and global sustainability. Particularly in growing cities in the developing world, such efforts can improve the well-being of billions of urban residents and contribute to mitigating climate change by reducing energy use in urban areas.

Environmental sustainability in practice a macro scale profile of tourist accommodation facilities in australia s coastal zone
Journal of Sustainable Tourism, 2008Co-Authors: Karen E Mcnamara, Chris GibsonAbstract:While methods have been developed to measure progress towards sustainability in a tourism setting, a shortage still exists of research that examines the integration of Environmental sustainability into the Existing Built Environment, particularly across a macro-scale. In an attempt to advance research in this area, this paper profiles the self-acknowledged implementation of Environmental initiatives by managers of tourist accommodation facilities along Australia's east coast. An original and empirical approach, based on quantitative surveys, was undertaken for 536 accommodation facilities located within one kilometre of the coastline. Broad trends were that larger accommodation facilities were more likely to be in close proximity to coastlines, yet were also more likely to have formal mechanisms to implement Environmental initiatives. Regional variation in implementation was apparent, and possible explanations included the role of local cultures and state regulation. Overall, however, results indicate poor uptake of Environmental initiatives. We conclude by arguing that such results are a consequence of barriers including the inheritance of older Built Environments and the poor communication to the managers of facilities of the benefits of implementing Environmental initiatives.

Efficient use of land to meet sustainable energy needs
Nature Climate Change, 2015Co-Authors: Rebecca R. Hernandez, Madison K. Hoffacker, Christopher B. FieldAbstract:An analysis shows that generation of solar power within the Existing Built Environment could easily meet California’s current energy demand. The deployment of renewable energy systems, such as solar energy, to achieve universal access to electricity, heat and transportation, and to mitigate climate change is arguably the most exigent challenge facing humans today^ 1 , 2 , 3 , 4 . However, the goal of rapidly developing solar energy systems is complicated by land and Environmental constraints, increasing uncertainty about the future of the global energy landscape^ 5 , 6 , 7 . Here, we test the hypothesis that land, energy and Environmental compatibility can be achieved with small- and utility-scale solar energy within Existing developed areas in the state of California (USA), a global solar energy hotspot. We found that the quantity of accessible energy potentially produced from photovoltaic (PV) and concentrating solar power (CSP) within the Built Environment (‘compatible’) exceeds current statewide demand. We identify additional sites beyond the Built Environment (‘potentially compatible’) that further augment this potential. Areas for small- and utility-scale solar energy development within the Built Environment comprise 11,000–15,000 and 6,000 TWh yr^−1 of PV and CSP generation-based potential, respectively, and could meet the state of California’s energy consumptive demand three to five times over. Solar energy within the Built Environment may be an overlooked opportunity for meeting sustainable energy needs in places with land and Environmental constraints.
