  • Simulation of Convective Heat Loss Through Mineral Wool in a Rainscreen Facade
    Simulation of Convective Heat Loss through Mineral Wool in a Rainscreen Facade M. Steven Doggett, Ph.D. and Robert F. Brunjes, AIA Built Environments, Inc., Stillwater, Minnesota, U.S.A. Abstract – This study applied Computational Fluid Dynamics (CFD) to determine the effects of wind- induced convection through mineral wool in a ventilated rainscreen system. Wind studies of a conceptual low-rise building subject to a wind speed of 6.7 m/s demonstrated dynamic airflows and rainscreen velocities ranging from 0.1 to over 3 m/s. Localized pressure fields near cladding support framing increased air velocities within the mineral wool by one to two orders of magnitude. These high pressure regions, together with increased surface flows at corner domains, represented the primary pathways governing convective heat loss. Simulated convection through mineral wool slabs showed that even high density materials are prone to increased heat transfer due to air permeability into the open pore volume. Vertical and horizontal flow regimes at 1 to 2 m/s increased heat transfer by 4 to 42% over the range of simulated mineral wool densities. Gaps between and behind insulation slabs further increased the convective effects, resulting in heat flux densities that were up to 62% higher than non-gapped, impermeable insulation. The results of this study support growing recognition that exterior mineral wool must be protected from the detriments of convective forces. Alternatively, adjustments in effective R- values should be made when using un-faced mineral wool slabs. 1.

  • Air Flow Control
    Understanding and Controlling Air Flow in Building Enclosures John Straube, Professor of Building Science, University of Waterloo, Waterloo, Canada [email protected] 1. Introduction It has long been recognised that the control of air flow is a crucial and intrinsic part of heat and moisture control in modern building enclosures [Wilson 1963, Garden 1965]. That this statement is true for all climates has been a more recently developed awareness [Lstiburek 1994]. A large fraction of a modern, well-insulated building's space conditioning energy load is due to uncontrolled air leakage. Wintertime condensation of water vapour in exfiltrating air (or summertime condensation of infiltrating air) within assemblies is one of the two major sources of moisture in the above-grade enclosure (driving rain being the other). Air flow through the enclosure can also carry, exhaust gases, odours, and sounds through enclosures as well as mould spores and off gassing generated within the enclosure. Uncontrolled air leakage through the enclosure is therefore often a major cause of performance (e.g. comfort, health, energy, durability, etc.) problems. Water vapour diffusion, while amenable to simple analysis, is often (but definitely not always) an insignificant source of moisture in modern building envelopes. Wintertime exfiltration condensation is, however, acknowledged as a common building performance problem in cold climates. Warm weather infiltration condensation is often a problem in warm and humid climates (e.g. the south-eastern States) and in some cases in cool climates, especially when air conditioning or cooling (e.g. arenas) is used. Therefore, there are three primary classes of reasons why the control of air flow is important to building performance: 1.
