CYPESOUND

Font size

The "Font size" option has been added to the general configuration menu of the applications. This tool allows users to increase or decrease the basic size of the font used in the user interface of the programs. Thanks to this implementation, the accessibility of the applications has been improved while also ensuring the correct visibility of the content on devices with different screen resolutions.

To enter a "Basic size" the "Set custom font size" option must be checked. The size users can enter is the application's basic font size. Any other font sizes that may exist in the program's interface will be automatically modified proportionally according to the change in the basic size.

It is important to note that, as this is a common parameter, its modification will affect all installed CYPE tools.

CYPESOUND is downloadable from BIMserver.center

As of version 2023.c, the following acoustic analysis applications can be downloaded from the BIMserver.center store and are no longer included in the classic CYPE software package:

  • CYPESOUND
    Design and verification of the sound insulation against airborne noise and impact noise, sound immission and reverberation level. It can be used internationally and installed in Catalan, Spanish, English, French, Italian and Portuguese.

  • CYPESOUND NRA
    Application of French acoustic regulations for residential houses, hotels and education buildings.

  • CYPESOUND DRAPDE
    Application of the Italian acoustic regulations in D.P.C.M. 5/12/1997.

These versions of CYPESOUND are added to CYPESOUND CTE (Spanish regulations) and CYPESOUND RRAE (Portuguese regulations) which are already available on this platform.

General improvements

Version 2021.g of CYPE’s programs is a closing version of the 2021 version.

As well as the new features and improvements expressly indicated in each version of CYPE software, process optimisation involving internal updates for all our programs is normally included. In each revision, all programs are systematically checked and changes are made to improve their performance, therefore, we recommend that our users (in this case those of v.2021) always update their version to the latest one, regardless of the country for which they are using CYPE software or the language in which it is installed.

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.
