This quick free EnergyPlus is directly related to the Quick Guide DesignBuilder published a few days ago. EnergyPlus is in fact the calculation engine DesignBuilder, but can also be used independently to manage px exchange or run simulations and thermal energy audits Advanced Building. Through EnergyPlus you full access to all the settings of the thermal model of a building as well as the detailed reports in output as the surface temperatures of the walls (not directly px exchange accessible in DesignBuilder).
The graphical interface of EnergyPlus is not very user-friendly. Input and output of the building is used to manage data tables that do not have automatic or graphic elements of simplification. To overcome this problem exist outside of graphical interfaces that facilitate the creation of the thermal model of the building and the inclusion of their characteristics. We are talking about DesignBuilder, Openstudio (plugin for Google SketchUp), px exchange Energy Plugged (plugin for Autocad) etc.
Overcome the problem of creation of the thermal model of the building, you can get in EnergyPlus and access all of the thermal characteristics of the building. You can edit and add input and output set in detailed reports, such as the surface temperature of the walls (not possible within DesignBuilder).

I offer technical advice on the rehabilitation of buildings, with particular attention to the building and cost-benefit analysis. px exchange
I would like to model an air unit that supplies air to the thermal zones. The plant must not necessarily carry out the function of space heating, but simply has to convey the fresh air in the served.
The only constraint px exchange exists, consists in the entry temperature px exchange of the environments. The input temperature of the air should be equal to the outdoor air temperature if this is> 18 C, while if the outside px exchange temperature is below 18 C by a resistance (electric coil) present on the Loop should raise the temperature of the flow air inlet and destined environments.
The circuit is organized according to the following chain: Exterior-> Heat recovery plate -> Resistance of any heating -> Input in the area-> Heat recovery plate -> Outside
I modeled the circuit with DesignBuilder but I'm working in Energy Plus. IDF's px exchange minimodello I'm talking to identify the rule of operation was used the object.

but from what I see from the output, known that the resistance will work, depending on the temperature of the outside air, but carries the input stream to 18 C required only during the coldest. Reading between the output variable temperature HEATING COIL AIR OUTLET NODE see that reach temperatures of 60 70 80 C, especially in summer. If I'm not mistaken, the operation desired by me should show that the temperature at that node should always be equal to the temperature
