Version history for SENIB

Here you can read a little about what's new and what has been improved in the different versions of SENIB.



SENIB gets its present structure

  • SENIB gets support for fully backward compatible updates in the future and you are now notified automatically if there is an update available when you open any “1NewHouse.ods” file. It is then also possible to update SENIB without visiting this web page.
  • SENIB is now available in English and Swedish and has the possibility to be translated into other languages by using a “language” file.
  • SENIB is tested compatible with the most common operating systems – Windows, Mac OS X and Linux.



Many small improvements

About 50 improvements but none of them critical.



Two new big functions added and a few smaller ones

  • Free outdoor temperature statistics
    Free automatic download of outdoor temperature statistics from many places in Sweden. This plugin is only available in Swedish. Contact us for more information about how to activate it.
  • 1-pipe systems
    SENIB can now with several different calculation methods be used to get pre-setting values for radiator valves in hydronic 1-pipe heating systems.

Faster execution of macros for many functions.

Visual improvements, mainly for Mac OS X.

Fixed bugs
Many non-important and one critical bug fixed. The critical bug concerned import of measurements from PDF files when the operating system is set to use a comma as a thousand separator. (Standard in the US.) E.g. 45,67 meters was imported as 4567 meters.



New functions

  • Support for PDF-XChange Editor
    If you in previous versions of SENIB wanted to measure blueprints in PDF-files then you had to use the program PDF-XChange Viewer. Now it's possible to use the successor PDF-XChange Editor which is free as well.
    You can read more about the PDF programs here.
  • Heating unit only used in summer
    Now it's possible in the sheet "Info" in the file 1NewHouse.ods to specify that the primary heating unit is only used during the summer, e.g. heating of hot tap water.

Improved usability

Comments added with help texts and more cells can warn for errors. E.g. now cells become red in the sheet "AptAdj" if values in cells exceeds the maximum opening value of the valve.

Fixed bugs
A few less important bugs fixed and one more serious. In the file 1NewHouse.ods, sheet "Other", cell G64 the wrong size of the pump was calculated if several identical houses is connected to the same central heating room and that was specified in cell L5 in sheet "Size", at the same time as the user has chosen to not specify the measurements of all apartments in every house by choosing "No" in cell H7 in the sheet "Apt".



Improved usability
Some comments added to better explain which type of data is required in certain cells.

Data for new radiator valves
There are now more valve types to choose from when calculating preset values for radiator valves in hydronic heating systems.

Fixed bugs
Some minor errors and one script error fixed. The script error occurred when performing calculations of energy use during a measurement period in the sheet "EnergyUse" in the file 1NewHouse.ods. This script error occurred only on Windows 10 after the major Redstone 5 operating system update was installed.



Updated support for outdoor temperature statistics
Now a lot more different formats of outdoor temperature statistics are supported when importing from local computer files.

Fixed bugs
Some minor errors and one larger error fixed that created problems when copying rows in some of the sheets in 1NewHouse.ods. The error only happened sometimes and only on Windows 10 after Windows 10 had been updated to version 1903.



Fixed bug
Fixed a bug that in certain cases could make it impossible to update to version 1.207 with the file 2UpdateSENIB.ods.



Fixed bugs
Fixed a couple of bugs that were introduced in version 1.207 of SENIB, that had to do with downloading of Swedish outdoor temperature statistics from SMHI.



Added support for import of measurement i CSV-files
It is now possible to import measurements from blue prints in UTF-8 CSV-format.

Fixed bugs
A small amount of less important bugs fixed.



Fixed bug
It is now possible to manually enter degree days and heating days after temperature statistics has been imported, if you are not satisfied with the imported statistics. Version 1.211 of the included file 1NewHouse.ods is required for it to work.



Fixed bugs
A bug was discovered that degree days was not exactly calculated correctly if you imported outdoor temperature statistics for a house located at the southern hemisphere and you also specified that you wanted to use more than one heating unit. This has now been fixed, as well as a bug that made a too big floor area to be entered into SENIB, under certain circumstances, if you imported CSV-files with measurements of a house.



Three major new features added

  • Cooling of the house
    Calculations for required energy need for cooling of the house can now be made.
  • Free outdoor temperature statistics from NASA
    Is used for example to obtain the number of HDD (Heating Degree Days) and CDD (Cooling Degree days). Imported automatically, if necessary, to SENIB directly from NASA's servers for any location in the world.
  • Pipe dimensions
    SENIB can now make calculations of which pipe dimensions are needed so that the head loss do not become too large in the heating system.

Several minor new features and improvements added, for example:

  • You can specify an alternative LOT (Lowest Outdoor Temperature) for the calculation of the radiator sizes.
  • You can specify that you don't want to heat the house during the winter.
  • Import of temperature statistics from possible.
  • Improved calculation of the supply temperature that different heating units need to be able to handle.
  • Improved calculation of the curve for the control unit when LOT is specified to be warmer than -2 degrees C.
  • It should now be possible to use SENIB with any decimal and thousand separator setting in the operating system and OpenOffice. Previously, a warning message was displayed if you had incorrect settings.



A new sheet, ZipPdf, in the file 1NewHouse.ods
The new sheet has two new features.
  • It is now easier to share a project with others by zipping all associated SENIB files from one project into a zip file and send it by email. Only the files used in that particular project are packed into the zip file.
  • You can also create a report in pdf format from the same sheet. In the report, you can get a comparison between different possible energy investments.
After version 1.500 was released, problems were discovered with downloading outdoor temperature statistics from NASA due to that NASA's servers use the https protocol. A lot of time has been spent making SENIB compatible with LibreOffice, which has full support for https pages. LibreOffice which is the currently recommended version is also for certain things much faster than OpenOffice. Unfortunately, old project files created with SENIB 1.500 or earlier are not compatible with LibreOffice 7.



Fixed bugs
A few fixed bugs when SENIB used with LibreOffice on Mac OS X.



Minor adjustments and spelling corrections
Adjustments mainly to make SENIB look better with LibreOffice.



Update mainly for SENIBportable.exe

The most important function of this update is to inform that you should update SENIBportable.exe if you are running the portable version of SENIB on Windows. Before LibreOffice was included in SENIBportable.exe but we have discovered that numbers such as 10.5 is sometimes rounded to 10 instead of 11 in the 7.1.x versions of LibreOffice which can give error messages in the form of red cells in SENIB. This issue does not persist in LibreOffice which is now included with SENIBportable.exe.

Other improvements are also made in this update that make it well worth updating SENIB anyway.



Update for newer versions of LibreOffice

This is primarily an update with an work around for a bug in newer versions of LibreOffice.

Some other minor adjustments to SENIB have also been made.



One new feature and some other minor updates

If you use the sheet ZipPdf in 1NewHouse.ods, you can now easily create charts of different energy consumption and operating costs for different types of configurations of a house.

Updates for statistics from NASA that gets a new layout on the NASA website.

Several other minor bug fixes.
