Shortcuts for all applications

CYPE apps have keyboard shortcuts common to all programs. In versions before 2024.e, each program displayed the keyboard shortcuts for each app via the "Search and activation of commands and options" in the top left-hand corner of the programs.

As of version 2024.e, the "Shortcuts for all applications" tab has been implemented in the dialogue box displayed when selecting this option and it shows all the keyboard shortcuts common to CYPE apps.

Exporting the calculated values of the indoor air temperatures of the zones to a CSV file

As a result of the simulation, a new file with .csv extension is produced which contains the calculated values of the indoor air temperatures of the zones and the outdoor air temperature, for each hour of the year. These numerical values coincide with those represented graphically in the complementary "Internal comfort" report.

The new temperature results file is available in the _dat directory next to the file containing the job:
… \ […]_dat\Energyplus\Project_cons.res\Zone air temperatures.csv

New assistants for entering energy conversion factors and site data

In the "Energy Sources" option, in the "Energy conversion factors" section, assistants have been added to load the national values for Spain, Portugal, Poland and Slovenia. Furthermore, users can import and export the values defined in this section in order to reuse them in other projects.

New calculation report for the reduction factor

Within the "Complementary reports", we have added the "Calculation of the reduction factor (b)" report, which contains the methodology and detailed results from the calculation of the heat transfer to the unconditioned spaces of the building in accordance with EN ISO 13789:2017.

The results provided in this new report are used in the calculation of the heat transfer coefficient of the building envelope report.

New descriptive report of the thermal envelope in the simulated model and limit transmittance checks

The results output of the program has been enhanced with the new "Building envelope" report, available in the toolbar of the "Analysis" tab. This new report, which can be accessed without having to analyse the model, provides the results of the transmission heat transfer coefficient calculated according to EN ISO 13789:2017 and the air permeability of the thermal envelope. A breakdown by elements is provided and the thermal transmittance (U) value of each element is compared with the limit value set by the user.

The limit transmittance values for each type of building element can be set in the "Building" tab, under "General parameters", where the new "Thermal envelope" section appears. By activating the "Boundary conditions of the thermal envelope" checkbox, the program will check the limit transmittance of the building elements both in the "Check" button of the model and in the new "Building envelope" report.

Also, in the "Air permeability of the building envelope" section, users can now define a "Limit value of the air change rate with a differential pressure of 50 Pa", which will also be checked in the new report.

Display floor view templates in the 3D view

For 3D views defined within applications with a 3D working environment, the "Show selected templates in each floor view" option has been added. When activated, the templates visible in each of the floor views will be displayed in the 3D view in the dimension corresponding to these views.

Managing the visibility of templates in the view configuration window

As of version 2024.c, applications with a 3D working environment can manage the visibility of templates from the view configuration panel. For this purpose, the "DXF-DWG templates" tab has been added, where a list of all the templates imported into the project is displayed together with a checkbox to indicate which ones should be shown in the view.

Installation modes (professional, campus, evaluation, temporary license)

All CYPE programs can be installed in their different versions (Professional Version, Evaluation Version, Campus Version, Temporary License). In previous versions, users could only choose the type of version to be installed from the classic CYPE menu.

As of version 2024.a, the selection of version types has been implemented in all CYPE programs on the BIMserver.center platform.

As of version 2024.d, this selection can be made during the installation of all CYPE programs, regardless of where they are downloaded.

Specific power for fans

As of version 2024.b, the energy consumption of fans included in air conditioning systems is defined by their specific power, i.e. their energy consumption per unit of air flow rate. This value is standard in the documents for these appliances and replaces the previous parameters of "Total pressure rise" and "Total efficiency". The program calculates these parameters, which are the input for the calculation engine, on the basis of the new "Specific power".

Heat recovery unit with an automatic bypass damper

A new automatic control of the heat recovery unit bypass damper has been included, which allows outside air to pass through when it is convenient to reduce cooling demands.

In previous versions, the bypass damper of the heat recovery unit was activated if the outside air temperature was within the limits selected by the user. In this new version, the damper will be activated automatically whenever the following conditions are met:

  1. The outside temperature is higher than the "Minimum outside temperature".
  2. The indoor air temperature is higher than the "Maximum indoor temperature".
  3. The outside temperature is lower than the inside temperature.

As of version 2024.b, the control of the heat recovery bypass damper is included in the calculation of the building's energy demand, which will lead to a reduction of the calculated cooling demands in buildings with air conditioning systems or ventilation systems that include this unit.

Direct expansion heating coil in the variable air flow air handling unit

In the air handling unit of the variable airflow system, under "Heating" users can now choose the Direct expansion Heating coil. This way, it is possible to simulate a compact rooftop unit with a variable airflow system and with both cooling and heating provided by the compressor.

Removal of restrictions on the combination of air conditioning systems

As of version 2024.b, it is possible to combine air-air conditioning systems in the same building. The following exceptions remain:

  • No more than one constant performance unit can be defined in the same zone.
  • No more than one terminal unit with a ventilation function can be defined in the same zone.
  • Combinations of air conditioning terminal units associated with different systems in the same zone are not permitted.

In previous versions, when defining air-air-conditioning systems in the building, there were restrictions that prevented placing more than one terminal unit of any type in the same zone or using more than one water-air conditioning system. As a consequence of the improved models for air-air conditioning systems (also implemented in version 2024.b), these restrictions have been removed.
