Оne day workshop for thermal bridge calculations for low energy buildings and Passive Houses.
A thermal bridge, also called a cold bridge, is a fundamental of heat transfer where a penetration of the insulation layer by a highly conductive or non-insulating material takes place in the separation between the interior and exterior building enclosure. Thermal bridging occurs wherever assembly components with high U-values relative to surrounding materials span from the inside to the outside of a building assembly.
The thermal bridges can result in:
- accelerated heat loss through that area
- localized cold spots on the interior of a wall that may cause a risk of condensation
A building that is thermal bridge free heeds less energy for heating, it is more economical, and it is healthier for its occupants.
THERM is a free software program provided by Lawrence Berkeley National Laboratory that analyzes two-dimensional heat transfer through building assemblies.
The participants of the course will learn how to calculate thermal bridges using THERM and Excel for use in the Passive House Design Package. Using this program they can verify the influence of the thermal bridges and how they can optimize them.
During the one day workshop the participants will be able to make a simulation for an old building, identify the thermal bridges, and calculate them. They will be able to optimize these details and develop thermal bridge free details and calculations, suitable for Passive Houses.
