Book Description
Natural products like wool, leather or cotton are permeable to water vapor. Their complex fibrous structure makes it difficult to imitate this natural phenomenon by synthesis. This book discusses ways to obtain water vapor permeability by microporosity or through a hydrophilic structure. Various areas of application include the medical sector for implants and dialysis, the industrial sector for filtration or for processes requiring the slow release of substances, and the consumer sector for leather substitutes or performance textiles.

Book Description
Almost all homes, apartments, and commercial buildings will experience leaks, flooding, or other forms of excessive indoor dampness at some point. Not only is excessive dampness a health problem by itself, it also contributes to several other potentially problematic types of situations. Molds and other microbial agents favor damp indoor environments, and excess moisture may initiate the release of chemical emissions from damaged building materials and furnishings. This new book from the Institute of Medicine examines the health impact of exposures resulting from damp indoor environments and offers recommendations for public health interventions. Damp Indoor Spaces and Health covers a broad range of topics. The book not only examines the relationship between damp or moldy indoor environments and adverse health outcomes but also discusses how and where buildings get wet, how dampness influences microbial growth and chemical emissions, ways to prevent and remediate dampness, and elements of a public health response to the issues. A comprehensive literature review finds sufficient evidence of an association between damp indoor environments and some upper respiratory tract symptoms, coughing, wheezing, and asthma symptoms in sensitized persons. This important book will be of interest to a wide-ranging audience of science, health, engineering, and building professionals, government officials, and members of the public.

Book Description
The new threshold for green building is not just low energy, it's net-zero energy. In The New Net Zero, sustainable architect Bill Maclay charts the path for designers and builders interested in exploring green design's new-frontier net-zero-energy structures that produce as much energy as they consume and are carbon neutral. In a nation where traditional buildings use roughly 40 percent of the total fossil energy, the interest in net-zero building is growing enormously--among both designers interested in addressing climate change and consumers interested in energy efficiency and long-term savings. Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding. Designers and builders will find a wealth of state-of-the-art information on such considerations as air, water, and vapor barriers; embodied energy; residential and commercial net-zero standards; monitoring and commissioning; insulation options; costs; and more. The comprehensive overview is accompanied by several case studies, which include institutional buildings, commercial projects, and residences. Both new-building and renovation projects are covered in detail. The New Net Zero is geared toward professionals exploring net-zero design, but also suitable for nonprofessionals seeking ideas and strategies on net-zero options that are beautiful and renewably powered.

Book Description
Permeability is a normalized term that is calculated based on vapor flow, vapor drive, and saturation pressures. However, it does not take into account the total volume of water vapor that is actually transmitting across a wall assembly at a given temperature and relative humidity. It also does not take into account other factors, which may include chemical diffusion and moisture content concentration. This paper will present water vapor transmission data collected on a variety of air barrier membranes, both permeable and non-permeable, at different temperatures and relative humidity. These data show a variation in permeability as a function of temperature; however, this is not reflected in ASTM E96, Standard Test Methods for Water Vapor Transmission of Materials, Methods A and B, the standardized perm rating often used by professionals to design wall assemblies. Hygrothermal analysis tools primarily use a permeability input based on relative humidity and do not directly consider temperature outside of the general Schirmer equation. This paper will provide an initial look at the implications of this limitation based on the vapor drive data through the use of hygrothermal analysis and wall assembly testing. The aforementioned may have intriguing implications on how we assess materials selected for exterior wall assemblies in construction. These same implications potentially influence how the industry establishes performance metrics and how they may relate to a wall assembly's actual performance. This paper will serve to initiate a candid discussion on the subject matter.
