Edge management

The 2017.e version of CYPETHERM LOADS and CYPEHERM EPlus has improved edge management. As of the 2017.e version, users can choose the code with which edges are to be analysed, so they can be detected as being thermal bridges (ISO 14683, ISO 14683- Italy, HE1 2006, HE1 2013, RT2005/2012 and REH).

This improvement has also been included in CYPETHERM RT2012 (France) and CYPETHERM RTExistant (France).

Integration of the lighting design results carried out in CYPELUX in Open BIM workflow

As of the 2017.b version, CYPETHERM EPlus and CYPETHERM LOADS allow users to import, using an IFC file, the results of the lighting analysis carried out in CYPELUX. This way, the programs can import the calculated installed lighting power in each precinct. Furthermore, users will be able to personalise this data in each precinct (only data in the type of precinct was available in previous versions).

Generation of linear thermal bridges

CYPETHERM HE Plus, CYPETHERM LOADS and CYPETHERM EPlus analyse linear thermal bridges to calculate the corresponding transmittance values, depending on the properties of the adopted construction solutions.

This analysis is carried out taking into account the specifications to be applied depending on the code that has been selected to calculate the thermal transmittance in linear thermal bridges.

BIM models contain the geometric description of the building, whereas technical information has to be introduced using specific programs.

Therefore, to detect linear thermal bridges, the program must carry out a two-stage analysis. During the first stage, ‘Edges’ are imported as purely geometric entities, obtained from the intersection of two different construction elements. The second stage consists of the ‘Linear thermal bridge analysis’ which obtains the linear thermal bridges and their corresponding transmittance values based on the edges, and depending on the properties of the adopted construction solutions and the description of the building from the thermal analysis point of view (zone distribution, space description, etc.).

Open BIM workflow in CYPETHERM programs

The specialised tools: CYPETHERM HE Plus, CYPETHERM LOADS, CYPETHERM HVAC and CYPETHERM EPlus, allow users to import geometric models in IFC4 format and export and import information related with the analysis and design of the building services of the building, which is obtained using the tools. This way the BIM model of the project is updated and the Open BIM workflow is closed.

The four CYPETHERM tools allow users to automatically generate a new job by importing a BIM file with geometric information. Furthermore, each tool can import any additional IFC files generated by the remaining specialised CYPETHERM programs which may contain useful information for its design when the job is created or at any time during the design process of the job.

As the work is not carried out exclusively with one IFC file containing geometric information of the project, but with a group of IFC files containing the geometric, analysis and design information of the project, each BIM project must be generated in an individual directory to have all the information in a single place and for programs to only read the corresponding IFC files.

One of the many benefits of the Open BIM workflow can be seen, for example, in CYPETHERM LOADS and CYPETHERM HVAC. From CYPETHERM LOADS all the information of the thermal loads of the precincts can be exported to IFC format, once the project has been analysed. CYPETHERM HVAC requires the information of the thermal loads of the building to design the air conditioning systems. This information can be introduced by users or can be imported from the BIM project, if the data has been exported from CYPETHERM LOADS.

Open BIM workflow: Consolidation

The group of programs integrated in the Open BIM workflow carried out the export and import of geometrical models in IFC4 format.

As of this version, as well as importing and exporting geometrical models in IFC4 format, the information regarding the analysis and design of building services, obtained using specialized programs (design programs) of CYPETHERM Suite, is also exported and imported. This way the BIM model of the project is updated and the Open BIM workflow is closed.

CYPETHERM Suite design programs allow users to automatically generate a new project by importing a BIM file with geometric information (BIM Project Starter). Now, additional IFC files containing useful information, and generated by the remaining specialized programs of CYPETHERM Suite, can be imported when the project is created or at any other stage (Update Specialized Models). As users do not only work with one IFC file containing geometric information but with a group of files containing the geometric, analysis and design information of a project, each BIM project must be generated in an independent directory to have all the information in a single location, and for the programs to only read the corresponding IFC files.

One of the many benefits of Open BIM workflow can be seen, for example with CYPETHERM LOADS and CYPETHERM HVAC.

Users can export from CYPETHERM LOADS, once the project has been analysed, all the information regarding the thermal loads of the precincts, in IFC format using the “Export” option.

CYPETHERM HVAC requires the thermal load information of the building to be able to carry out the analysis and design of air conditioning systems. This information can be introduced by users or can be imported from the BIM project, if the data has been exported from CYPETHERM LOADS.

Export from CYPECAD MEP

As of the 2015.f version, CYPECAD MEP allows users to export jobs to CYPETHERM ASHRAE LOADS from the Air conditioning tab, as has been indicated in the new features of CYPECAD MEP.

Tables, graphs and charts for each job element

As of the 2015.e version, CYPETHERM ASHRAE LOADS has broadened its immediate result output to offer a better understanding of the calculations that have been carried out and provide the analysis of the effects each component of the job has on the final result of the thermal loads.

To do so, the program provides tables, graphs and charts for each element of the job and are updated when components are added or properties are modified, without having to print out the report of the results, allowing user to carry out a direct and immediate analysis.

The tables, graphs and charst that are visible for each job element are grouped in a drop-down menu called “Results analysis”. This menu also contains the “Overview calculation” option, which, when selected, provides the detailed calculations for each component and the parameters that have been considered. This way, a justification report of the heating and cooling thermal load calculation process is obtained.

Report improvements

The reports have been improved and different graphs have been included to offer a global view of the results.

Report configuration

The 2015.d version of the program includes a helpful tool to configure the results report, which allows, amongst other things, to include the different sections that are available as well as select the type of load of each precinct to be included, even the specific moment for the cooling thermal loads.

Availability in other languages

In the 2015.b version, the program, CYPETHERM LOADS was implemented. This application was conceived to analyse the thermal loads of buildings in accordance with the Radiant Time Series Method (RTSM) proposed by ASHRAE.

The first version of CYPETHERM LOADS was only available in Spanish and in English. Now, with the 2015.d version, the program is also available in Catalan, French, Italian and Portuguese. Furthermore, the name of the program has changed to CYPETHERM ASHRAE LOADS for all languages.

Change of program name

As of the 2015.d version, the program is called CYPETHERM ASHRAE LOADS, becoming a part of the CYPETHERM program group of CYPE.
