Affordable Cold Climate Infill Housing with Hybrid Insulation Approach, Wyandotte, Michigan (Fact Sheet).


Book Description

Even builders who are relatively new to energy-efficient construction can consistently reach a target whole house airtightness of 1.5 air changes per hour at 50 Pascals (ACH50) with high R-value enclosures that use a hybrid insulation approach. The City of Wyandotte, Michigan, started a construction program in 2010 to build affordable, energy-efficient homes on lots in existing neighborhoods. A goal of the program was to engage local builders in energy-efficient construction and be able to deliver the new houses for less than $100/ft2. By the end of 2012, approximately 25 new houses were built by five local builders under this program. To help builders consistently achieve the airtightness target, a local architect worked with researchers from Building Science Corporation, a U.S. Department of Energy Building America team, to develop a technology specification with several key pieces. A high R-value wall and roof assembly made use of 2?6 advanced framing and a hybrid insulation approach that included insulating sheathing to control thermal bridging and closed cell spray polyurethane foam insulation (ccSPF) for its airtightness and vapor control benefits. This approach allows the air barrier to be completed and tested before any finishing work occurs, ensuring that problems are spotted and corrected early in the construction process.

Climate Stabilization Targets


Book Description

Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Emissions reductions decisions made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia. According to Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia, important policy decisions can be informed by recent advances in climate science that quantify the relationships between increases in carbon dioxide and global warming, related climate changes, and resulting impacts, such as changes in streamflow, wildfires, crop productivity, extreme hot summers, and sea level rise. One way to inform these choices is to consider the projected climate changes and impacts that would occur if greenhouse gases in the atmosphere were stabilized at a particular concentration level. The book quantifies the outcomes of different stabilization targets for greenhouse gas concentrations using analyses and information drawn from the scientific literature. Although it does not recommend or justify any particular stabilization target, it does provide important scientific insights about the relationships among emissions, greenhouse gas concentrations, temperatures, and impacts. Climate Stabilization Targets emphasizes the importance of 21st century choices regarding long-term climate stabilization. It is a useful resource for scientists, educators and policy makers, among others.

Know Your Price


Book Description

The deliberate devaluation of Blacks and their communities has had very real, far-reaching, and negative economic and social effects. An enduring white supremacist myth claims brutal conditions in Black communities are mainly the result of Black people's collective choices and moral failings. “That's just how they are” or “there's really no excuse”: we've all heard those not so subtle digs. But there is nothing wrong with Black people that ending racism can't solve. We haven't known how much the country will gain by properly valuing homes and businesses, family structures, voters, and school districts in Black neighborhoods. And we need to know. Noted educator, journalist, and scholar Andre Perry takes readers on a tour of six Black-majority cities whose assets and strengths are undervalued. Perry begins in his hometown of Wilkinsburg, a small city east of Pittsburgh that, unlike its much larger neighbor, is struggling and failing to attract new jobs and industry. Bringing his own personal story of growing up in Black-majority Wilkinsburg, Perry also spotlights five others where he has deep connections: Detroit, Birmingham, New Orleans, Atlanta, and Washington, D.C. He provides an intimate look at the assets that should be of greater value to residents—and that can be if they demand it. Perry provides a new means of determining the value of Black communities. Rejecting policies shaped by flawed perspectives of the past and present, it gives fresh insights on the historical effects of racism and provides a new value paradigm to limit them in the future. Know Your Price demonstrates the worth of Black people's intrinsic personal strengths, real property, and traditional institutions. These assets are a means of empowerment and, as Perry argues in this provocative and very personal book, are what we need to know and understand to build Black prosperity.




Climate Change in the Great Lakes Region


Book Description

People living in the Great Lakes region are already feeling the effects of a changing climate. Shifts in seasonal temperatures and precipitation patterns could have dramatic impacts on the economy, ecology, and quality of life. In this illuminating and thorough volume, leading scholars address the challenge of preparing for climate change in the region, where decision makers from various sectors—government, agriculture, recreation, and tourism—must increasingly be aware of the need to incorporate climate change into their short- and long-term planning. The chapters in this revealing book, written by some of the foremost climate change scholars in North America, outline the major trends in the climate of the Great Lakes region, how humans might cope with the uncertainty of climate change impacts, and examples of on-the-ground projects that have addressed these issues.




International Perspectives on Gender and Higher Education


Book Description

Despite improved access to higher education for women, the distribution of women and men varies considerably between fields of study. The chapters in this edited collection explore the participation status of women in higher education across the varying socio-economic and sociological backgrounds observed in different countries and regions.
