Building Location: Calgary Chicago Cincinnati Edmonton Minneapolis Montreal New York City Ottawa Seattle Toronto Vancouver

Building Dimensions:

• length =
  m


• width =
  m


• floor height =
  m

Percentage of Windows: %

Percentage of Balconies: %

Thermally Broken Balconies?(*): Yes No

Wall R-Value: m2K/W

Window U-Value: W/m2K

Calculate 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
