Release notes

Renovation:

  • Choose to specify detailed energy prices per month for heating and electricity in the Compare step

Renovation:

  • Input for CO2 impact from the building’s energy use is enabled in the Compare-step

  • Select several building objects and merge them into one building in Model from map

Both Evaluation and Renovation

  • Define area/length/volume as a matematical expression
  • Possibility to automatically subtract the window area from exterior wall area to ease the input when defining the building components

Standard

  • New step in the workflow, Standard, to compare the calculation result to the permitted levels in the Swedish Boverket’s building resultations (BBR)  (primary energy number EP_pet, average U_value, installed electric input for heating)
