Features

• Download Reports in PDF format
• Improved ‘Show / Hide Vertices and Distances’ in the 3D – Visulatization (With an right mouse click). Select vertices to show the distance between them.

Bugfixes

• Drain water heat recovery is now automatically set as addtional dhw device.
• Improved Sketch Up import with higher error tolerance. windows which where not on the same plane as the wall are now cut out of the wall and no longer overlap.
• updated confusing error messages (e.g. if a assemlby include no layer).

05.08.2025

Features

• Add ‘Show / Hide Vertices and Distances’ in the 3D – Visulatization (with an right mouse click). Select vertices to show the distance between them. (In development)

Bugfixes

• shown U-values and Thermal resistance were not converted correctly to IP-Units in the user interace.
• The check for the lowest design flow temperature was decreased for hydronic heating.
• Fixed an issue with inhomogenous Assemlies within imported *.mpw projects. The setting of subdivisions was different.
• Fixed the utilisation factor for Laundry Dryer in combination with an simplified domestic hot water calculation.

7.07.2025

• fixed and with internal loads – the ‘inside conditioned space’ box did not remain checked

25.06.2025

• Hot water piping uses Design flow temperature only from optional in conditioned space input in the general tab
• Design flow temperature is checked to be within 105°F and 180°F (fixed an error for negative dhw heat losses due to lower flow temperature than interior air temperature)
• added user setting pannel e.g. for global SI-IP unit setting
• removed hvac device coverage for mechanical ventialation (it is set via the selected rooms)
• added input validation for system-to-zone coverage (fix an error for zero heating/cooling source energy). A system must be asigned to a zone, if a device is defined.
• small correction calculating the thermal resistance for inhomgenous assemblies
• shown U-value and thermal resistance for assemelies is now converted to IP-unit
• fixed renewable energy set the ph case loading an mwp (fixed regarding the renewable energy)
• updated phius window database to point to the correct shgc value (center-of-glass, not whole window)
• (internal) improved calculation methodology
• (internal) error logging
• (internal) prepared language translation

08.04.2025

• fixed some input issues for new METr porjects (not imported), including:
  • assing a material to an assembly
  • transparent compoment total solar transmittance
• check before deleting assinged compoments
• (internal) improved calculation dependencies
• (internal) error logging

26.03.2025

• Fixed an bug for assigned ventilation units for ducts and ventilated rooms for ventilation units.
• Added daily swing temperature in the monthly climate data
• Fixed source energy target calcualtion
• Corrected IP units in the passive verification report

26.03.2025

• Add version number
• Add default wind speed (9.8 mph) in climate data and ground thermal conductivity (1.1556 Btu/hr ft)
• Fixed some input boxes losing focus if sending project for results
• Fixed an error don’t let assign assemblies to components (because of same ID’s)
• Fixed SI/IP convertion for PH case floor area in user interface, was not affecting the calculation
• Fixed an error assign material for exchange material in inhomogenious assemblies due to differnt horizonal and vertical subdivisions in different layers.
• Fixed user interface for water storage. Used for dhw or space heating is moved to the device input form
• Fixed an error not showing near climate data if latitude and longitude was an input in the climate data form and not an input on the climate map.
• System device usage coverage is now regarding all systems
• upload also *mwp files
