Release notes

Release 2021-12-17

Proxy

  • The user gets full flexibility to define the building components by activating Proxy-data for the building to manually define the input
  • 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)
  • Primary energy number as indicator

  • ‘Energy performance’ as new key value and presentation in the report 
  • Possible to include heat recovery from waste water to pre-heat tap water
  • Average value of the schedule for ‘Usage’ and ‘Ventilation’ is presented to give a quick overview of the indata

  • New functionality for ‘Interior walls’ to include the heat capacity of interior walls in the calculation
  • New functionality ‘Compound material’  for calculating the material properties for a material with both thermal insulation and studs
  • Add ‘Solar panels’ in the calculation and use the solar power for electricity supply
  • Possibility to add ‘Outdoor air intakes’ on the fasades to provide the building with outdoor air and keep the underpressure at a reasonably low level in buildings with exhaust air ventilation
  • New keyword ‘Internal air pressure’
  • Activated result indicators are saved on the user
  • Added report content for material properties, constructions and building components

  • New step in the workflow ‘Compare’ – A comparison of the heat and electricity supply between building altertntives in a project is generated
  • Peak power heating and electricity is added as Key values

  • Use air-tight interior floors in the modeling of the building
  • The module Catalog with the possibility to define new catalogs to use in projects

  • To examine the result in Excel, it is now possible to export the result to text file

  • Schedule for usage and ventilation flows are included in the report seption
  • Possibility to adjust the value for heated floor area generated from the 3D model
  • Impact from thermal bridges are added to the calculation when including basement in the building
  • New heat pumps from Bosch, IVT and Nibe are added to the default catalog
  • Windows with constant solar shading are added to the default catalog

  • Windows can be added to the calculation both as share of facade (%) and area (m2)
  • Possible to use ‘Default time’ instead of weekday when generating schemes for usage and Ventilation

  • Generating schemes for usage and ventilation are greatly improved with respect to speed and ease of use
  • Choose from one day to another when generating schemes, and ‘Hour to/from’ is replaced with ‘Start time/End time’ (time)
  • How the schemes are varying over the year is shown under ‘Details’. Possible to view a certain week.
  • Tutorials of the workflow are accessible within the application

  • Snap interval 0.5m in ‘Edit floor plan’
  • Possibility to change the construction of separate building parts with ‘Change building parts’
  • Copy the scheme from supply air to exhaust air and vice versa
  • English version available

  • Add several air handling units with different properties and air flow schemes
  • Function ‘’Export to VIP-Energy’. The area of the buildings parts and their constructions are exported and can be opened in VIP-Energy
  • Climate files for 2018 and 2019 from Sveby/SMHI are available
  • ’Copy’ is added in the name of a construction when a copy is created in the catalog
  • Possible to create an alternative of a typology, usage template and ventilation system by using ‘Create alternative’- ‘Alternative’ will be added in the name of the new created building

  • Possibility to add a lowest exhaust air temperature for exhaust air heat pumps
  • Air flow unit l/s is added

  • Exhaust air temperature and room temperature are added as indicators and can now be included in diagrammes in the report
  • Include basement in the building
  • Connect a geothermal rock heat pump to heat recovery from the exhaust air instead of to a ground source collector

  • Share building with access to write with another user
  • How many hours the heat pump has been out of order due to high/low temperature is printed out

  • New section in the report: ‘Surrounding conditions’, ‘Building’, ‘Heat supply’, ‘Cooling’ and ‘Specification of energy supply’
  • New indicators in the categories ‘Electricity’ and ‘Process energy’
