EC709 calculates the linear thermal transmittance of thermal bridges as a function of selected design parameters according to the procedures defined in the standards EN ISO 10211 and EN ISO 14683.
EC709 can be used either stand-alone or as an additional module fully integrated within EC700 Energy performance calculation software.
For each thermal bridge, EC709 provides the geometric model, the qualitative trend of the flow lines and isotherms, the possibility of choosing the structures involved in the thermal bridge for easier characterisation (functionality only present in the integrated version in EC700), and the linear thermal transmittance values.
EC709 supports the critical surface temperature check, to avoid surface condensation on the thermal bridge. This check can be performed varying both internal and external boundary conditions.
