Building air leakage databases in energy conservation policies: analysis of selected initiatives in 4 European countries and the USA

January 2, 2013
Author(s)
Wanyu Chan, Francois R. Carrie, Jiri Novak, Andres Litvak, Fabrice Richieri, Oliver Solche, Wei Pan, Steven Emmerich
We collected information on existing envelope air leakage databases from countries that are involved in the AIVC-TightVent project "Development and applications of building air leakage databases". This document summarizes the information from five

An Assessment of Methods for Determining Wind Loads

January 1, 2013
Author(s)
Emil Simiu, Chris Letchford, Nicholas Isyumov, Arindam Chowdhury, DongHun Yeo
The purpose of this work is to present an assessment of methods for determining wind loads on buildings and other structures that warrant comment, correction or improvement. The assessment is intended to serve as a resource as a new version of the American

Smoldering in Flexible Polyurethane Foams: the Effect of Foam Morphology

December 18, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D. Davis, Jeffrey W. Gilman, Li Piin Sung, Douglas M. Fox, Shivani N. Mehta
Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion. Flexible polyurethane foams (PUF) are prone to smoldering due to their high air permeability, low density and high specific surface

Multi-zone Modeling of Size- Resolved Outdoor Ultrafine Particle Entry into a Test House

December 11, 2012
Author(s)
Dong H. Rim, Andrew K. Persily, Lance L. Wallace, William S. Dols, Steven J. Emmerich
Airborne particle transport into buildings is important for human exposure to particles and associated health effects. The present study investigated the entry of size-resolved outdoor ultrafine particles into a test building under three different

Social Disorder, Accidents, and Municipal Wildfires

December 1, 2012
Author(s)
Douglas S. Thomas, David T. Butry, Jeffrey P. Prestemon
Societal safeguards, established by those who have shared perceptions in the importance of safety and taking preventative measures, reduce the incidence of accidents that harm people and damage property. These safeguards prevent or discourage community

Energy Price Indices and Discount Factors for Life-Cycle Cost Analysis - 2012

November 26, 2012
Author(s)
Amy S. Rushing, Joshua D. Kneifel, Barbara C. Lippiatt
This is the 2012 edition of energy price indices and discount factors for performing life-cycle cost analyses of energy and water conservation and renewable energy projects in federal facilities. It will be effective from April 1, 2012 to March 31, 2013

Modeling of Reinforced Concrete Assemblies under a Column Removal Scenario

November 8, 2012
Author(s)
Yihai Bao, Hai S. Lew, Sashi K. Kunnath
This paper presents a computational investigation of two reinforced concrete beam-column assemblies, each comprising three columns and two beams, subjected to monotonically increasing vertical displacement of the unsupported center column simulating a

Indoor Air Quality Analyses of Commercial Reference Buildings

November 1, 2012
Author(s)
Lisa C. Ng, Amy Musser, Andrew K. Persily, Steven J. Emmerich
Sixteen commercial reference buildings were created in the multizone airflow and contaminant transport program CONTAM in order to support airflow and indoor air quality (IAQ) analyses, which are not possible using the existing EnergyPlus input files for

Factors Influencing the Smoldering Performance of Polyurethane Foam

September 26, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D. Davis, Jeffrey W. Gilman, Shivani N. Mehta
The objective of this study was to evaluate whether polyurethane foam (PUF) could be produced as a standard reference material for ultimate use in a standard test intended to ensure the smoldering performance of commercially available upholstered furniture

Evacuation of People with Disabilities on Stairs

September 18, 2012
Author(s)
Erica D. Kuligowski, Bryan Hoskins, Richard D. Peacock, Emily A. Wiess
The time that it takes a population to reach safety when descending a stairwell during building evacuations is typically described by measureable engineering variables. These engineering variables include stairwell geometry, speed, density, and pre

More Thoughts on Defaults

September 18, 2012
Author(s)
Steve M. Gwynne, Erica D. Kuligowski, Michael Spearpoint
In this paper, the use of default values in egress models is explored and specific values are proposed to combat issues of model misuse. The authors suggest that defaults should represent the most credibly conservative estimates available for core egress

Annex 47 Extended Project Summary

September 17, 2012
Author(s)
Natascha S. Milesi-Ferretti, Daniel Choiniere
In 2006, researchers from 22 organizations in ten countries began a joint effort to enable the cost-effective commissioning of existing and future buildings to improve the buildings’ operating performance. The commissioning techniques developed through

This report summarizes part of the work of IEA-ECBCS Annex 47 Cost-Effective Commissioning of Existing and Low Energy Buildings. It is based on the research findings from the participating countries. The publication is an official Annex report. Report 1,

Commissioning Cost-Benefit and Persistence of Savings: A Report on Cost-Effective Commissioning of Existing and Low Energy Buildings

September 17, 2012
Author(s)
Hannah Friedman, Marti Frank, David Claridge, Kristin Heinemeier, Kim Crossman, Eliot Crowe, Cory Toole, Natascha S. Milesi-Ferretti, Daniel Choniere
Commissioning of new and existing buildings has been shown to reduce energy usage and can also produce non-energy related benefits such as improved occupant comfort. When compared with other initiatives such as installation of high efficiency equipment or
