The laboratory and/or field sites used for this work are not certified rating test facilities. The conditions and methods under which products were characterized for this work differ from standard rating conditions, as described. Because the methods and conditions differ, the reported results are not comparable to rated product performance and should only be used to estimate performance under the measured conditions. v Contents List of Figures .

The authors also recognize Michael Baechler, Manager of the Building America program at PNNL. This work would not be possible without the inspiring dedication of time and effort from Samuel Taylor and the members of the Joint Committee on Building Science Education. The authors would also like to express deep appreciation to the many participants not mentioned by name who helped with the development of the Guidelines for Building Science Education.

In 2002, the weather in the Andes changed, generating temperatures as low as -16 degrees Fahrenheit (-26 degrees Celsius), creating major heating deficits in the majority of the adobe houses. "Totora" (Schoenoplectus Tatora), an aquatic plant that grows in Lake Titicaca at 12,500 ft (3,810 meters) above sea level, available in most rural areas in Puno, is sold as an inexpensive mattress. Samples of woven mats of Totora were exported from Peru and tested in a laboratory at the University of Minnesota following the ASTM Standard C1155 to find its R-value. The results indicate that the Totora 'mattress' has an R-value that is approximately eight times higher than adobe of the same thick...

The standard is expressed as a definition of a water separation plane followed by a set of three requirements. The requirements are applicable to the envelope components on the interior and exterior sides of the water separation plane and on the interior side only when the exterior side components are structurally and biotically inert. The standard is discussed using experimental data to illustrate salient features. Application examples for an above-grade wall system and a commercial roof system are presented and their hygrothermal performance evaluated in terms of the universal standard requirements.

The configuration of the structures was based on the most recent surveys conducted by U.S. Census Bureau and National Association of Home Builders. The designs reflected the local building codes valid in pertinent areas, including building envelope design. Alternative steel framing was designed such that the thermal properties matched the ones for the wood frame.

A sample easement consistent with the requirements of Iowa's solar access easement law is included. This methodology minimizes the restrictions on the burdened lot while affording excellent protection for the lot with the solar system. It provides the owner of the burdened lot with
