Impact of Structural Thermal Breaks on Heating Energy

A simple analysis for the early conceptual stage of the design. (The plan will be redrawn for every input update. For the numerical results click on 'Calculate').

Building Dimensions:

length = m

width = m

floor height = m

Percentage of Windows: %

Percentage of Balconies: %

Thermally Broken Balconies?(*):

Wall R-Value: m2K/W

Window U-Value: W/m2K

annual heat losses:

Heat losses through the wall: kWh %

Heat losses through the windows: kWh %

Heat losses through the balconies: kWh %

Total heat losses: kWh kWh/m2

Savings from the use of thermal breaks in balconies:
kWh
%
kWh/m2

(*) the following typical linear transmittance values may be used, if no project specific ones are available

Linear transmittance of conventional (unbroken) balconies = W/mK

Linear transmittance of thermally broken balconies = W/mK
