Update history​

CYPESOUND

64-bit Version

As of the 2019.f version, CYPE programs (those downloaded from our website and those downloaded from the BIMserver.center platform) are compiled for 64-bit systems. The 64-bit compilation of CYPE software implies the use of the superior features of 64-bit processors and operating systems compared to those of 32 bits.

Please bear in mind that you must have a 64-bit operating system to be able to work with any 64-bit software.

In any case and as a temporary measure, the 2019.f version is available in 64 and 32 bits on the download area of our webpage. The programs that can be downloaded from the BIMserver.center platform are only available in 64 bits. If you have a 64-bit operating system, you can work with either the 64-bit and 32-bit version of our software, although we strongly recommend that you install the 64-bit CYPE software version.

You can see which operating system is installed on your computer by clicking on "Control panel > System".

Since 64-bit microprocessors began to be massively introduced into personal computers from 2003 and from the Windows XP version, Microsoft already offers the two versions of its operating systems (32 and 64 bits). We understand that almost all our users will have computers with 64-bit processors (x64) and 64-bit operating systems.

It could occur that a user may wish to work with a computer with a 64-bit processor but with a 32-bit operating system. It would be very strange if the computer had a 32-bit processor (x86 - computers over 15 years old). If any of these is your case, we advise you to talk to your hardware or software provider to update your situation as soon as possible. However, you can download the 32-bit version and work with CYPE programs that can be downloaded from our website until your situation is up-to-date.

Reading of electrogen groups of the “Open BIM Inmesol” application as sound sources

As of the 2019.a version, all CYPESOUND programs (CYPESOUND, CYPESOUND CTE, CYPESOUND NRA, CYPESOUND RRAE and CYPESOUND DRAPDE) and AcoubatBIM by CYPE are able to read electrogen groups from the BIM model and add them to the program as noise sources. During the import process, the application automatically calculates the values of parameters "r" (distance between the source and the closest enclosure of each affected area) and "D" (directivity factor of the machine) corresponding to each set, based on the position of the source and the geometry of the building.

These devices can be introduced in the BIM model using the new application: “Open BIM Inmesol”, which is available on the BIMserver.center platform.

Export project documents to the BIM model

The option to “Export” to IFC has been implemented in the “BIM model” group of the toolbar in all CYPESOUND programs (CYPESOUND, CYPESOUND CTE, CYPESOUND RRAE and CYPESOUND DRAPDE) and in AcoubatBIM by CYPE. This option allows users to integrate the justification reports of the project in the BIM project, in .pdf format. These reports can be viewed directly using the BIMserver.center platform and its mobile applications for Android and iOS.

Adjacent spaces in thermal and acoustic programs

When CYPE thermal and acoustic programs import an IFC file that does not contain information on adjacent spaces, they analyse the file and the layout of the spaces to detect what type of spaces are adjacent to them.

As of previous versions, these adjacent spaces were included automatically in the IFC files that are generated by IFC Builder (free CYPE application designed for the creation and maintenance of IFC building models), as this program generates them. Other CAD/BIM programs (such as Allplan®, Archicad®, Revit®...) do not export this information to IFC files, hence, if one of these programs was being used as the initial tool of the BIM model, the boundaries had to be defined by users in each specialised acoustic and thermal application.

With this important new feature of the 2018.j version, information on adjacent spaces is included in CYPE thermal and acoustic programs, regardless of which CAD/BIM program is used as the geometric modeller of the Open BIM project.

Below is a list displaying the thermal and acoustic programs CYPE has available that benefit from this new feature:

Import outdoor sound sources from the BIM model

Implemented in the 2018.g version of CYPESOUND was the functionality of reading and interpreting the indoor sound sources defined in an IFC file included in the BIM model. The same task has now been carried out for outdoor equipment such as the outdoor units of VRF, Multi-split and 1x1 Split systems. These devices can be introduced in the BIM model using the CYPETHERM HVAC air-conditioning installations design program.

During the import process, the application automatically calculates the values of the parameters r (distance between the source and the closest façade of each affected area) and D (directivity factor -Q- of the machine) corresponding to each equipment set, which depend on the position of the source and geometry of the building.

Edit outdoor equipment

The way in which equipment outside the analysed is defined has been improved. Now, instead of indicating the presence of the outdoor sound source in each affected space, a new section has been created in the “Model” tab in the tree diagram of the building, where users can introduce them once.

For each set of outdoor equipment, users must indicate its type, directivity factor (Q) and the spaces that are affected as well as the value of the distance of the closest façade to each space (r).

Import sound sources from the BIM model

As of the 2018.g version, CYPESOUND (in English), CYPESOUND CTE (in Spanish), CYPESOUND RRAE (in Portuguese) and CYPESOUND DRAPDE (in Italian) are capable of reading and interpreting correctly indoor sound sources that have been defined in the BIM model. This was already being carried out for terminal elements of air conditioning ducts such as grilles and diffusers.

The IFC entities that are recognised by the application, and can be exported to the BIM project by other Open BIM programs of CYPE, include:

  • Bathtubs and showers. These objects, together with the remaining sanitary equipment, can be introduced using the free BIM modeller, IFC Builder.
  • VRF, Multi-split and Split 1x1 systems. The same way grilles and diffusers can be introduced in CYPETHERM HVAC.
  • Terminal air conditioning duct elements (available as of the 2017.e version). This consists of grilles and diffusers. To insert these devices, the BIM program for design of air conditioning installations can be used: CYPETHERM HVAC.

During the import of the BIM model, the application automatically calculates the directivity factor (D) and the radius of the greatest sphere that can be inscribed in the space (r) for each source.

Sound sources can also be imported from the BIM model using this version of AcoubatBIM by CYPE.

Outdoor airborne noise on façades

As has been implemented in AcoubatBIM by CYPE, as of the 2018.f version of CYPESOUND and CYPESOUND NRA (France), users can force the limit value of the insulation against outdoor noise of a specific façade. If this option is selected, the program will check the level of insulation obtained for the façade with this new value instead of that indicated in the general parameters of the application.

Furthermore, in CYPESOUND NRA (France), an assistant is included to determine this limit based on “l’arrêté du 30 mai 1996 modifié en juillet 2013”.

Spectrum adaptation term

As has been implemented in AcoubatBIM by CYPE, as of the 2018.f version of CYPESOUND, users can tell the program to add the spectrum adaptation term C or Ctr (depending on the predominant type of noise) to the acoustic insulation index against outdoor airborne noise.

Reverberation time and equivalent acoustic absorption area depending on volume

As of the 2018.f, as has been done in AcoubatBIM by CYPE, a new formula has been added in CYPESOUND to limit the reverberation time and equivalent acoustic absorption area of a space depending on its volume.

Façade groups

The option “Group of façades” has been added to the “Design options” panel of CYPESOUND.

Using this option, users can configure the way in which the outdoor airborne noise insulation is to be verified. As well as the individual analysis of each façade that has been carried out up to now, it is now possible to combine all the façades and check the insulation of the complete envelope of each space. The program also allows for adjacent façades with the same orientation to be grouped and then determines the insulation of these combined elements. Finally, the possibility also exists to group façades depending on their type (façade, roof or overhang), and calculate each group of insulation.

General options

All the information regarding design options and acoustic index limits that are used have been grouped in the “General parameters” panel.

Thanks to this implementation, it is now possible to create diverse acoustic requirements, for example, based on different national codes, and save this information with the aim to use it later in other projects.
