Information

Version 0.1.0, December 11th, 2011

This is the first version integrated in the IDEAS tool and made available for the public.

Version 0.2.0, January 26th, 2015

Major changes compared to v0.1 are:

• *.TMY3 is used as default climate file and its reader is adopted from the LBNL Buildings library.
• The IDEAS/Buildings/. package is updated so that the building components only require a single connector to be connected with the zone.
• All hydronic components in IDEAS/Fluid/. are defined and updated based on the IEA EBC Annex60 models.

Version 0.3.0, September, 2016

Major changes compared to v0.2 are:

• Added code for checking conservation of energy
• Added options for linear / non-linear radiative heat exchange and convection for exterior and interior faces of walls and floors/ceilings. Respective correlations have been changed.
• Overall improvements resulting in more efficient code and less warnings.
• The emissivity of window coatings must now be specified as a property of the solid (glass sheet) and not as a property of the gas between the glass sheets. This is only relevant if you create your own glazing.
• Merged Annex 60 library up to commit d7749e3
• Expanded unit tests
• More correct implementation of Koschenz's model for TABS. Also added the option for discretising TABS sections.
• Added new building shade components.
• Removed inefficient code that would lead to numerical Jacobians in grid.
• Added new AC and DC electrical models.

Version 1.0.0, January 12, 2017

Major changes compared to v0.3 are:

• IDEAS 1.0 is based on Annex 60 version 1.0.
• The IDEAS packages have been restructured to be more in line with the Annex 60 package structure.
  IDEAS.Constants has been replaced by IDEAS.Types
  The SimInfoManager has been moved to IDEAS.BoundaryConditions
  Interfaces such as HeatingSystem and BaseCircuits have been moved to IDEAS.Templates
• Setting up new Construction records has been simplifiedParameter values of nLay and nGain are now inferred from the other parameters.
• Optional parameter incLastLay has been added to Construction recordsUsers may use this to double-check if InternalWalls are connected as intended.
• The way how internal gains may be connected to surfaces has been changed.
• Convection and thermal radiation equations have been tuned to be more accurate and faster.
• Added an option to the zone model for evaluating thermal comfort.
• Added an option to the zone model for computing the sensible and latent heat gains from occupants.
• The zone air model is now replaceable such that custom models may be created.
• A zone template has been added that allows to add a rectangular zone, including 4 walls, 4 optional windows, a floor and a ceiling.
• Some variables have been renamedA conversion script is provided for converting the user's models to accomodate these changes.
  TStar has been renamed into TRad in the zone model.
  flowPort_Out and flowPort_In have been renamed in the zone model, heating system, ventilaiton system and structure models.
  Some Annex 60 models were renamed.
• Added example model of a terraced house in IDEAS.Examples.PPD12
• Added twin house validation models in IDEAS.Examples.TwinHouse
• Added solar irradiation model for window frames.
• Added optional thermal bridge model for windows.
• Extended implementation of building shade model.
• Fixed bug in view factor implementation.
• Updated documentation for many models in IDEAS.Buildings
• Added thermostatic valve model: IDEAS.Fluid.Actuators.Valves.TwoWayTRV
• Removed insulationType and insulationThickness parametersThese should now be defined in the Construction records.
• Harmonised implementation of Perez solar irradiation model with Annex 60 implementation.
• Cleaned up implementation of BESTEST models.
• Added new, specialised window types.
• Added options for model linearisation.
