Surface Filter

On the Tree View, click on the '+' symbol for the Output Filters folder, and then select one of the pre-defined filters or click on one that you have created yourself. On the screen you will now be able to tick various options and decide upon what sort of information that you want to be able to see when you view the results. The options have been grouped into three different areas. You can see results for the building, which will give you the total loads over all zones and will cover variables such as diffuse radiation, cloud cover, and external temperature. You can also filter the results by zones, and by surfaces. This topic will now describe the options from which you can select with respect to the SURFACE FILTER.

 

This section contains surface parameters. When viewing graphs based on surface parameters, the Output Selection must contain surfaces and the correct surface output specification for the required parameters.

 

Internal Temperature

The temperature of the near side of the selected surface. This value is displayed in degrees centigrade.

 

External Temperature

The temperature of the far side of the selected surface. This value is displayed in degrees centigrade.

 

Internal Solar Gain

The amount of solar gain absorbed by the near side of the selected surface. Displayed in Watts.

 

External Solar Gain

The amount of solar gain absorbed by the far side of the selected surface. Displayed in Watts.

 

Aperture Flow In

The amount of air flowing in through the selected aperture. Displayed in kilograms per second.

 

Aperture Flow Out

The amount of air flowing out through the selected aperture. Displayed in kilograms per second.

 

Internal Condensation

The amount of condensation on the near side of the selected surface. This value is displayed in grams per square metre.

 

Interstitial Condensation

The amount of condensation within the construction of the selected surface. This value is displayed in grams per square metre.

 

External Condensation

The amount of condensation on the far side of the selected surface. This value is displayed in grams per square metre.

 

Internal Conduction

The amount of heat transfer through the fabric of the construction. If the value is positive, the heat is being transferred to the near side of the surface. If it is negative, it is being transferred away. This value is displayed in Watts.

 

External Conduction

The amount of heat transfer through the fabric of the construction. If the value is positive, the heat is being transferred to the far side of the surface. If it is negative, it is being transferred away. This value is displayed in Watts.

 

Aperture Opening

The area of the opening as a percentage of the total surface area.

 

Internal Long Wave

The amount of long wave radiation absorbed by the near side of the surface minus the amount of long wave radiation radiated by the surface. This value is displayed in Watts.

 

External Long Wave

The amount of long wave radiation absorbed by the far side of the surface minus the amount of long wave radiation radiated by the surface. This value is displayed in Watts.

 

Internal Convection

The amount of energy transferred between the internal air and the near side of the surface. If it is positive, the air is heating the surface. if its negative the surface is heating the air. The value is displayed in Watts.

 

External Convection

The amount of energy transferred between the external air and the far side of the surface. If it is positive, the air is heating the surface. if it is negative the surface is heating the air. The value is displayed in Watts.
