PresentationOutline

Many energy standards, heat loss calculations, and whole building simulations still overlook thermal bridging, or use simplified building envelope details when calculating building heat transfer.  This often neglects significant contributions to heat loss, particularly at wall system connections.  As wall systems, thankfully, become better insulated under more stringent energy codes, the impact from thermal bridges represents a much larger percentage of the overall building energy loss.  Ignoring them will result in overestimating thermal performance and designers will miss the opportunity to mitigate problem details before it becomes impractical to do so.  In these situations, predicted energy performance often falls short of reality with few options for real improvements once construction is done.  The ASHRAE 1365 research on thermal bridging was completed nearly 15 years ago and provided a simple means for the industry to make more accurate thermal transmittance calculations for incorporation into whole building energy simulations. This presentation will look at where we have come from in addressing thermal bridges in building envelopes, how far we have made it along the path to thermal truth, and where we need to go as a building industry.  It will also include an example of how the powerful online version of the Thermal Bridging Guide can be used to get a far better prediction of building energy loss.
