Forensic Investigation Of Building Failure – The Harbour Cay Condominium Disaster, John Airis
Forensic Investigation Of Building Failure – The Harbour Cay Condominium Disaster, John Airis
Publications and Research
When a building suffers collapse, the U.S. Occupational Safety and Health Administration (OSHA) is tasked with conducting an investigation into the cause. Often OSHA will request technical assistance from the National Institute for Standards and Technology to assist in the forensic technical aspects determining a most probable cause. This forensic effort entails many actions. The Harbour Cay Condominium disaster occurred on March 28, 1981 in Cocoa Beach, Florida. It was a total collapse of a five story reinforced concrete structure during the last stage of roof construction, resulting in 11 deaths and 24 injuries. The investigation report revealed structural design …
Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang
Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang
Publications and Research
The current methods for the prediction of the heat flow through building entrance doors have been used for years while involved with a certain degree of uncertainty. This paper describes an experimental method that accurately quantified such heat flow. The experiment monitored local environmental parameters in a college building on a cold winter day. The results of the experiment demonstrated that the experimental method is viable to accurately estimate the heat flow throughout the entrance doors and the presence of a vestibule moderated heat losses from the conditioned area. The results will be used for validating the existing methods.
Competence Of A Spray Passive Down-Draft Evaporative Cooling (Pdec) System For Space Cooling, Daeho Kang, Richard K. Strand
Competence Of A Spray Passive Down-Draft Evaporative Cooling (Pdec) System For Space Cooling, Daeho Kang, Richard K. Strand
Publications and Research
A spray PDEC system has been relatively less considered than other passive cooling strategies as one of the viable low-energy solutions in the cooling of buildings while having a great potential in energy savings. This study is intended to evaluate the capability of a spray PDEC system for space cooling. It comprises four simulation scenarios to see the system response and influence of indoor thermal environment when a spray PDEC system is adopted as a primary cooling system in two different climates. The simulation results show that a spray PDEC system causes a substantial variation in the indoor thermal environment …
Analysis Of The System Response Of A Spray Passive Downdraft Evaporative Cooling System, Daeho Kang, Richard K. Strand
Analysis Of The System Response Of A Spray Passive Downdraft Evaporative Cooling System, Daeho Kang, Richard K. Strand
Publications and Research
A spray Passive Downdraft Evaporative Cooling (PDEC) system achieves great savings for space cooling and improves indoor environmental quality by supplying a large amount of fresh outdoor air. As previous studies heavily focused on the energy saving capability of a spray PDEC system due to lack of methods for a detailed analysis, the influence of cool humid supply air from a spray PDEC system in a space in buildings has not been comprehensively studied. This study is intended to evaluate the competence of a spray PDEC system as a primary cooling system in typical spaces in a primary school building …
