Aikaisemmat versiot
Alla lista aikaisempien ESBO versioiden tärkeimpiin uusiin ominaisuuksiin.
Uutta versiossa 2.2
Spectral properties of glass panes and shading materials
Spectral calculation is introduced for glazing and integrated sunshades. This means that the properties of the whole glazing/sunshade system are calculated for each wavelength interval. Spectral calculations give higher accuracy than non-spectral. For modern glazing and shading materials, non-spectral calculations can give significant errors (> 10%) and viable system combinations may be missed. Spectral data can be uploaded by manufacturers at any time and is automatically synchronized with user databases.
Overheating calculation
Overheating calculation is a new simulation type to automatically find the worst day for rooms that have no or limited mechanical cooling.
Enthalpy wheel heat exchanger
An air handling unit with a new rotary heat exchanger model, based on prEN 16798-5-1, is introduced. It has three options with different types of coatings:
|
New types of integrated shading
Three new types of typical shading devices can now easily be selected for the window; Micro lamellas (shading dependent on two angles), Venetian blinds between panes and Screens between panes. Access to manufacturer data for shading materials has been enabled.
New model for heat from occupants
Thermal comfort is calculated in ESBO according to ISO 7730. In ESBO 2.1 and earlier, the heat loss from a person that is too cold (PMV < 0) was larger than the specified metabolism. In ESBO 2.2, the clothing level is adjusted instead so that the PMV value becomes close to zero, which means that the total heat losses always become equal to the metabolism. This change only applies to the calculation of occupant heat. The calculation of PMV/PPD is not affected.
External shading1
It is now possible to also add and edit horizontal shades in Building 3D and shading.
Exhaust air heat pump
An exhaust air heat pump is now available in ESBO. It is quick and easy to set up a heat pump with liquid-coupled exhaust air heat recovery and storage tank. Sizing of flow rate and heat pump is supported.
Heat exchanger cooling recovery
Cool recovering in air handling unit can be turned off to show how much power and possible energy this function is saving.

New cooling load calculation
A new cooling load calculation algorithm with automatic detection of “the worst day of the year” has been implemented, using monthly extreme weather data from the ASHRAE Fundamentals 2013 database. For modern buildings with low transmission losses, room cooling loads may peak in February or March, not during the summer as could be expected. The new method will detect this automatically. It will also automatically save peak design days for each zone and air handling unit as well as for the primary cooling system.
Results
Results of multiple simulations are now saved with the project file, and a new report for each simulation type has been added. In the paid version of ESBO two new result tabs can be opened; Summary and Details. The Summary tab includes summary tables for the rooms, air handling units and the building. For cooling load calculations, a summary of individual peak cases is presented. The Details tab features new ways of presenting multiple diagrams together, and it uses snapping crosshairs for easy reading.
Manufacturer data
Manufacturer data for room units and solar protection devices are now available directly in ESBO.
Batch runs and comparative report1
All open ESBO cases can now be run with a single mouse click. The results from all these simulations are shown in one comparative report.
Fan-coil model
A new dedicated fan-coil model is available that has more appropriate parameters and that is numerically more efficient. By setting the fan-power to zero, this model can also be used as an “ideal unit” that connects to the hydronic system.
Compressed binary file format
The default option is now to save the entire ESBO project in one single binary file. This makes it easier to copy ESBO projects and to incorporate them in file handling systems.
