Spray Polyurethane Foams in External Envelopes of Buildings presents, for the first time, a book focused on both the theoretical and practical design and applications of spray polyurethane foam (SPF) use. To review the moisture performance of SPF, this book focuses on the design of an assembly where moisture is kept from accumulating and causing deterioration (flow through approach). In this approach, Spray Polyurethane Foam presents two unique parts of theory and practice of various SPF products. FROM THE PREFACE Part 1 of this monograph analyzes SPF performance as the material (product). Being field fabricated, installation of SPF products must include a quality assurance program . . . Laboratory evaluation of foams and their coverings, quality management issues, and quantification of the technical support provided to the SPF contractor are also reviewed. Part 2 presents a systems approach to construction. Starting with principles of environmental control of buildings, different aspects of design and performance of roofing and wall systems are reviewed. Details and design recommendations . . . as well as case studies . . . are included.

With the improved efficiency of heating, cooling and lighting in buildings crucial to the low carbon targets of all current governments, Building Science: Concepts and Applications provides a timely and much-needed addition to the existing literature on architectural and environmental design education. Taking a logical and didactic approach, the author introduces the reader to the underlying concepts and principles of the thermal, lighting, and acoustic determinants of building design in four integrated sections. The first section explores the thermal building environment and the principles of thermal comfort, translating these principles into conceptual building design solutions. The author examines the heat flow characteristics of the building envelope and explains steady state design methods that form the basis of most building codes. He discusses the sun as a natural heat source and describes the principles of active and passive solar building design solutions. The second section introduces the scientific principles of light, color, and vision, stressing the importance of daylight in building design, presenting the Daylight Factor design concept and methodology, and discussing glare conditions and their avoidance. It also addresses artificial lighting, delving into the prominent role that electricity plays in the production of light by artificial means and comparing the efficacy and characteristics of the various commercially available light sources in terms of the energy to light conversion ratio, life span, available intensity range, color rendition properties, and cost. The third section deals with the various aspects of sound that impact the design of the built environment, discussing the nature of sound as a physical force that sets any medium through which it travels into vibration and laying the foundations for the treatment of sound as an important means of communication as well as a disruptive disturbance. The final section discusses the foundational concepts of ecological design as a basis for addressing sustainability issues in building design solutions. These issues include the embedded energy of construction materials, waste management, preservation of freshwater and management of graywater, adoption of passive solar principles, energy saving measures applicable to mechanical building services, and the end-of-lifecycle deconstruction and recycling of building materials and components. Covers the fundamental building science topics of heat, energy, light and sound Takes a logical and didactic approach, tracing the historical roots of building science Includes summaries of new technologies in solar energy and photovoltaic systems Features a section on the principles of sustainable architecture Website with answers to MC questions testing students' learning

Advanced Building Envelope Components: Comparative Experiments focuses on the latest research in innovative materials, systems and components, also providing a detailed technical explanation on what this breakthrough means for building exteriors and sustainability. Topics include a discussion of transparent envelope components, including intelligent kinetic skins, such as low-e coatings, high vs. low silver content in glass, solar control coatings, such as silver vs. niobium vs. tin, and more. In addition, opaque envelope components are also presented, including opaque dynamic facades, clay lining vs. plasterboard and nano clayed foams. - Includes real case studies that explore, in detail, the behavior of different envelopes - Presents laboratory tests on existing insulation (if any, through samples extracted on-site) to quantify actual performances - Provides the tools and methods for comparing, selecting and testing materials and components for designing effective building envelopes - Covers both transparent and opaque envelope components, as well as opaque dynamic facades

Master's Thesis from the year 2011 in the subject Art - Architecture / History of Construction, grade: none, University of Minnesota - Twin Cities (College of Design), language: English, abstract: Exterior envelopes for Passive Houses in very cold climates have not been developed, tested, and used as extensively as those in more mild climates such as central Europe. The purpose of this investigation was to push that development further by testing and comparing the performance of a variety of North American and Scandinavian envelope types that have been used in limited numbers for Passive Houses in those regions. A group of eight envelopes were selected and tested with a number of software analyses: Athena life cycle analysis, WUFI hygrothermal modeling, and THERM and EN ISO 6946 2-D U-value calculations for thermal bridging. Finally, the Passive House Planning Package (PHPP) was used to confirm that the envelopes met Passive House energy performance requirements in a very cold climate using a basic passive solar house design. Although significant variation was found in the performance of these eight envelope types, almost all of them were found capable of meeting the energy efficiency and thermal bridging requirements of the Passive House certification in a very cold climate, while maintaining moisture safety, durability, and significant life-cycle energy and carbon savings. These findings demonstrate that even in cold climates, a variety of envelope types can be used successfully for certified Passive Houses. Envelope types: 1) Advanced 2x6 framing24” on center with interior cross strapping and exterior insulation, insulated with mineral wool, 2) Advanced 2x6 framing24” on center, insulated with high-density spray polyurethane foam and exterior rigid foam, 3) Double 2x4 stud wall with studs 16” on center, insulated with blown cellulose, 4) I-joist (TJI) balloon framing 24” on center, insulated with blown fiberglass, 5) Insulated concrete form wall (ICF), using integral rigid EPS foam insulation, 6) Concrete block wall, insulated with exterior mineral wool, 7) Massivtre/Structural engineered panel (SEP), insulated with exterior rigid foam, and 8) Structural insulated panel (SIP), using integral EPS rigid foam insulation. For comparison, a base option was also studied: Standard 2x6 framing 16” on center with fiberglass batt insulation. See Appendix for diagrams of each envelope.
