Building America Case Study


Book Description

Over one million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with four PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost-effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing, and measures that improve equipment efficiency. ARIES documented implementation in 18 housing units. Reductions in average air leakage were 16 percent and duct leakage reductions averaged 23 percent. Total source energy consumption savings due to implemented measures was estimated at 3-10 percent based on BEopt modeling with a simple payback of 1.6 to 2.5 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

Whole-House Solutions for Existing Homes


Book Description

The Philadelphia Housing Authority worked with the U.S. Department of Energy's Building America Program to integrate energy-efficiency measures into the refurbishment process that each unit normally goes through between occupancies.




An Urban Politics of Climate Change


Book Description

The confluence of global climate change, growing levels of energy consumption and rapid urbanization has led the international policy community to regard urban responses to climate change as ‘an urgent agenda’ (World Bank 2010). The contribution of cities to rising levels of greenhouse gas emissions coupled with concerns about the vulnerability of urban places and communities to the impacts of climate change have led to a relatively recent and rapidly proliferating interest amongst both academic and policy communities in how cities might be able to respond to mitigation and adaptation. Attention has focused on the potential for municipal authorities to develop policy and plans that can address these twin issues, and the challenges of capacity, resource and politics that have been encountered. While this literature has captured some of the essential means through which the urban response to climate change is being forged, is that it has failed to take account of the multiple sites and spaces of climate change response that are emerging in cities ‘off-plan’. An Urban Politics of Climate Change provides the first account of urban responses to climate change that moves beyond the boundary of municipal institutions to critically examine the governing of climate change in the city as a matter of both public and private authority, and to engage with the ways in which this is bound up with the politics and practices of urban infrastructure. The book draws on cases from multiple cities in both developed and emerging economies to providing new insight into the potential and limitations of urban responses to climate change, as well as new conceptual direction for our understanding of the politics of environmental governance.




Integral Sustainable Design


Book Description

This book offers practical and theoretical tools for more effective sustainable design solutions and for communicating sustainable design ideas to today's diverse stakeholders. It uses Integral Theory to make sense of the many competing ideas in this area and offers a powerful conceptual framework for sustainable designers through the four main perspectives of: Behaviours, Systems, Experiences and Cultures. It also uses human developmental theory to reframe sustainable design across four levels of complexity present in society: the Traditional, Modern, Postmodern, and Integral waves. Profuse with illustrations and examples, the book offers many conceptual tools including: - Twelve Principles of Integral Sustainable Design - Sixteen Prospects of Sustainable Design - Six Perceptual Shifts for Ecological Design Thinking - Five Levels of Sustainable Design Aesthetics - Ten Injunctions for Designing Connections to Nature




Microsensing Networks for Sustainable Cities


Book Description

This book explores the microsensing technologies and systems now available to monitor the quality of air and water within the urban environment and examines their role in the creation of sustainable cities against the background of the challenges posed by rapid urbanization. The opening section addresses the theoretical and conceptual background of microsensing networks. The coverage includes detailed description of microsensors, supported by design-specific equations, and clear explanation of the ways in which devices that harvest energy from ambient sources can detect and quantify pollution. The practical application of such systems in addressing environmental impacts within cities and in sustainable urban planning is then discussed with the aid of case studies in developing countries. The book will be of interest to all who wish to understand the benefits of microsensing networks in promoting sustainable cities through better delivery of information on health hazards and improved provision of data to environmental agencies and regulatory bodies in order to assist in monitoring, decision-making, and regulatory enforcement.
