The energy efficiency of a building depends on building envelope performance. The results presented in this paper are the first of a long-term building envelope research project at the Alternative Village at the University of Manitoba in Winnipeg, Manitoba, Canada. Five test buildings were constructed using the following systems: two wood frames with fiberglass batt insulation and dense pack cellulose, one polyurethane structural insulated panels (PUR SIP), and two with the Stay in place PVC concrete form building system using 102mm and 204mm of concrete externally insulated with 102mm of expanded polystyrene foam. All of the buildings had a common foundation and roof system with a footprint of 23.8 m2. Blower door tests were conducted to determine air tightness. Each structure was heated with an electrical resistance heater and maintained at a constant internal temperature. The thermal gradient through the wall and power consumption were monitored. The study period discussed in this report represents the main heating season from October 2011 to April 2012 consisting of 209 days. Based on the power consumption, the PUR SIP consumed the least at 2498 kWh, while the 204 mm Stay in place PVC concrete form building used the most at 2898 kWh for the same time period. The thermal gradient through the cross section of the wood frame structures was compared through the cavity insulation and at the stud. It was found that the cellulose building provided better thermal resistance along the stud when compared to the fiberglass batt insulation.

This article presents the results of an investigation to obtain the constant effective thermal conductivities of intumescent coatings under the influence of different intumescent coating factors (type of intumescent coating, coating thickness, steel section factor, fire condition), based on the analysis of an extensive collection of fire test data. The constant effective thermal conductivity is not a fundamental property of the intumescent coating, but is a desired quantity for simplified practical fire resistance design. It is defined as the temperature-averaged value of the temperature-dependent effective thermal conductivity within the temperature range of interest for fire resistance design of steel structures. The results indicate that for each of the intumescent coating types examined, a consistent constant effective thermal conductivity exists. The constant effective thermal conductivity tends to increase with decreasing steel section factor and to decrease with increasing coating thickness. For intumescent coating–protected steel I-sections, incorporating the shadow effect gives more consistent values of constant thermal conductivity compared to those without accounting for the effect. The same constant effective thermal conductivity obtained from the ISO fire tests may be used for different fire conditions as long as the steel temperature is higher than 400 °C. The results of this research make it possible to develop a simple method to calculate temperatures of intumescent coating–protected steel sections under different fire conditions.

Steel Frame Structures

The problem of estimation of fire resistance of steel frame structures with intumescent coatings is considered. It implies that both physical properties of a covering (its thickness and structure) and mechanical properties of a metal structure change critically at heating. All above changes should be considered to maintain the standard values of fire resistance of a construction at calculation. Usually, known technical characteristics of fire resistance of intumescent coverings are used for estimation of fire resistance of steel structures with intumescent coverings. Importance of taking into account the influence of strength loss time at heating of a steel structure on calculation of fire resistance limit of system “intumescent fireproof coating steel structure” is shown in the article. On an example of calculation of heating time to the critical temperature of steel columns and beams protected by intumescent coating, it is shown that own heating time of steel structures before they lose strength makes 10 to 16 % from a settlement limit of fire resistance. This fact should be considered at the forecast of fire resistance of steel frame structures with intumescent coatings.

Abstract. In this study, controlled qualitative comparative experiments regarding the behavior of several insulation materials such as autoclaved aerated concrete, ignifugated wood panels, decorative insulation panel, expanded polystyrene and plasterboard to fire exposure have been assessed. Strong deformation has been observed after 5-20s of fire exposure, followed by advanced charring of the exposed area. In the case of polystyrene and ignifugated wood, intense and irritant aerosols occurred.
