American Society of Heating, Refrigerating, and Air-Conditioning Engineers. ISBN 1-883413-98-2. (This manual by ASHRAE discusses the design of cooling equipment to include dehumidification performance. Design analysis includes peak outdoor air dew point performance as well as peak outdoor temperature analysis.) Lstiburek, Joseph. Understanding Retarders. ASHRAE Journal. August 2004. (This ASHRAE Journal article covers the underlying principles of vapor retarders in buildings.) Lstiburek, Joseph 2004. Understanding Vapor Barriers. ASHRAE Journal 46:40 (This ASHRAE article describes water vapor dynamics in wall sections and provides a flow-chart method of selecting materials for the inside and outside of cavity walls with appropriate water vapor permeability for specific climates. Assemblies can be designed without using computer simulation.) Henderson, H., Shirey, D., Raustad, R. Understanding the Dehumidification Performance of Air Conditioning Equipment at Part-Load Conditions. Presented at the CIBSE/ASHRAE Conference, Edinburgh, Scotland 1-24-26 September 2003. (This technical paper presents analysis and data on the degradation of dehumidification performance of air conditioning equipment during partial-load conditions. Controls and systems that contribute to this problem are discussed.) MOIST (MOIST is a hygrothermal modeling program available as a free download from the National Institute of Science and Technology [http://www.nist.gov/el/highperformance_ buildings/performance/moist.cfm]. Accessed November 6, 2013. The calculation kernel in MOIST is not as complex as HygIRC or WUFI, but it is significantly better than simplified steady state dew point-temperature profile calculations. It provides a thermal network analysis, includes solar radiation gains (but not rainwater or plumbing leaks), capillary migration and partial-pressure-driven vapor migration. Like WUFI and HygIRC, MOIST does not model airflow effects.) HygIRC (A hygrothermal modeler from the Institute for Research in Construction in Canada [http://archive.nrc-cnrc.gc.ca/ eng/projects/irc/hygirc.html]. Accessed November 6, 2013. HygIRC is a modeler that is actively supported by the IRC. Like WUFI and MOIST, HygIRC assumes no air flow through the assembly.) National Asphalt Pavement Association. Online. Internet. Available at http://www.asphaltpavement.org/. (The National Asphalt Pavement Association is a trade association that provides technical, educational, and marketing materials and information to its members and that supplies technical information concerning paving materials.) International Code Council (ICC). 2003 ICC International Building Code. (Chapter 18 provides code requirements for soils and foundations including requirements for excavation, grading and fill around foundations. Section 1203.3.1 contains requirements for ventilated crawl spaces.) National Institute of Building Sciences (NIBS). Building Envelope Design Guide (Whole Building Design Guide). Online. Internet. Available at http://www.wbdg.org/design/envelope. php. Accessed November 6, 2013. (Under guidance from the Federal Envelope Advisory Committee, the NIBS developed this comprehensive guide for exterior envelope design and construction for institutional/ office buildings. Sample specifications and sections are included.) International Code Council. 2003 ICC International Plumbing Code. (Chapter 11 provides code requirements for storm drainage, including roof drainage requirements. Sections 312.2 to 312.5 specify a gravity test of the drain and vent side of plumbing systems.) International Code Council (ICC). International Energy Conservation Code (IECC). (The IECC addresses energy efficiency in homes and buildings.) Odom, J.D. and DuBose, G.H. Mold and Moisture Prevention. National Council of Architectural Registration Boards. Washington, DC, 2005. (This manual is the 17th monograph in NCARB's Professional Development Program. It contains substantial narrative describing moisture and mold problems in buildings and specific design and construction considerations for enclosures and HVAC systems as they relate to moisture and mold problems.) Kanare, H. Concrete Floors and Moisture, Portland Cement Association, Skokie, Illinois, cat. no. EB119, 156 pp., 2005. Lstiburek, Joseph 2006. Understanding Attic Ventilation. ASHRAE Journal 48: 36. (This ASHRAE Journal article covers the underlying principles of attic ventilation in buildings.) Rose, William. Water in Buildings: An Architect's Guide to Moisture and Mold. John Wiley & Sons, 2005. ISBN: 0471468509 (This is not a design guide, but rather a deeper look at water and its behavior in regard to building materials, assemblies and whole buildings. Illustrated with specific examples, it explains the how and why of moisture control.) Lstiburek, Joseph 2006. Understanding Basements. ASHRAE Journal 48: 24 (This article identifies moisture control problems often observed in basements and solutions to such problems.) Lstiburek, Joseph 2006. Understanding Drain Planes. ASHRAE Journal 48: 30 (This ASHRAE Journal article covers the underlying principles of rainwater control in buildings, focusing on the use of weather-resistant materials that provide shingled drainage beneath siding materials.) 65
