Assessing Juvenile Salmonid Passage Through Culverts: Field Research in Support of Protocol Development

Description: The primary goal of our research this spring/ summer was to refine techniques and examine scenarios under which a standardized protocol could be applied to assess juvenile coho salmon (O. kisutch) passage through road culverts. Field evaluations focused on capture-mark- recapture methods that allowed analysis of fish movement patterns, estimates of culvert passability, and potential identification of cues inducing these movements. At this stage, 0+ age coho salmon fry 30 mm to 65 mm long (fork … more

Closed Crawl Space Performance: Proof of Concept in the Production Builder Marketplace

Description: This overview is intended to be a very concise, limited summary of the key project activities discussed in the detailed report that follows. Due to the large scope of this project, the detailed report is broken into three individually titled sections. Each section repeats key background information, with the goal that the sections will eventually stand alone as complete reports on the major activities of the project. The information presented herein comes from ongoing research, so please note t… more

Building America Industrialized Housing Partnership (BAIHP)

Description: This final report summarizes the work conducted by the Building America Industrialized Housing Partnership (www.baihp.org) for the period 9/1/99-6/30/06. BAIHP is led by the Florida Solar Energy Center of the University of Central Florida and focuses on factory built housing. In partnership with over 50 factory and site builders, work was performed in two main areas--research and technical assistance. In the research area--through site visits in over 75 problem homes, we discovered the prime ca… more

Analysis of 2009 International Energy Conservation Code Requirements for Residential Buildings in Kansas City, Missouri

Description: The 2009 International Energy Conservation Code (IECC) contains several major improvements in energy efficiency over the 2006 IECC. The notable changes are: (1) Improved duct sealing verified by testing the duct system; (2) Increased duct insulation; (3) Improvement of window U-factors from 0.40 to 0.35; and (4) Efficient lighting requirements. An analysis of these changes resulted in estimated annual energy cost savings of about $145 a year for an average new house. Construction cost increases… more

Truss-Integrated Thermoformed Ductwork Final Technical Report

Description: This report summarizes a multi-year research effort to develop a leak-free duct system that can be readily installed within the thermal envelope. There are numerous efforts underway to improve duct system efficiency. Most of these involve modifications to current technology such as air sealing techniques like mastic and aeroseal, snap together duct connections, and greater levels of insulation. This project sought to make a more significant stride forward by introducing a duct system of a mater… more

Will Duct Tape and Plastic Really Work? Issues Related to Expedient Shelter-In-Place

Description: Expedient sheltering involves the use of common materials to enhance the safety of a room inside a building against the impacts of a chemical plume. The central premise behind taping and sealing with duct tape and plastic is to reduce airflow into a room. This paper reviews issues associated with the use of expedient sheltering materials and the effectiveness of this strategy. Expedient sheltering provides additional protection to people sheltering in place beyond that provided by the house and… more

Longevity of duct tape in residential air distribution systems: 1-D, 2-D, and 3-D joints

Description: The aging tests conducted so far showed that duct tape tends to degrade in its performance as the joint it is applied to requires a geometrical description of a higher number of space dimensions (1-D, 2-D, 3-D). One-dimensional joints are the easiest to seal with duct tape, and thus the least to experience failure. Two-dimensional joints, such as the flexible duct core-to-collar joints tested in this study, are less likely to fail than three-dimensional collar-to-plenum joints, as the shrinkage… more
