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.
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.
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.
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.
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.
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.
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".
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:
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.
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.
As of version 2024.b, it is possible to combine air-air conditioning systems in the same building. The following exceptions remain:
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.
The EnergyPlus calculation models used to simulate the air handling units in air-air conditioning systems have been changed. In the previous version (2024.a), this transformation began with the air handling unit of the constant air flow system. In version 2024.b, this change has been completed by also transforming the air handling units of the variable-flow and dual-duct air-air conditioning systems.
In previous versions, a "template" type model available in the calculation engine was used, which presented configuration and combination restrictions with other systems in the same job. With the change of model in version 2024.a and 2024.b, these restrictions have been removed. In addition, the definition interface of these systems has been organised into tabs to make it clearer.
As of version 2024.b, applications with the "Element selection tool" (this tool was implemented in version 2021.e) have the ability to move the selected model components with the arrow keys on the keyboard. The elements shall be moved on the work plane of the active view in the direction of the arrow key. Whenever the arrow is pressed, the distance that is displaced is constant, so zooming will make it larger or smaller.
