Calculation of gtot in the presence of certificates

N.B: The procedures explained in the articles in this manual are possible only if you intall KIT CE 3.8, click on "Online updates" to install it

Job order that includes only Shutters

• Select the shutter in the job order and open the General Data Type panel.

• Select the File:KeyData5.png button to open the "Type Data in the Job Order" panel and the File:KeyCE.png button to access the normative data panel

• Match the EN 14501 standard
• Enter under Solar reflectance', the certificate of the shutter previously uploaded in the Certification archive

N.B: The color chosen in the type should correspond to the certificate for Solar Reflectance, in this way the program links the color of the type to the value of the certificate

• Enter under 'Solar transmittance, the property of the shutter stated in the certificate.

N.B: These properties indicate how much solar energy is transmitted through the product under consideration. With a shutter with adjustable slats we can associate a solar transmittance opaque when the closed slats do not allow solar energy to pass through; in the case where there is passage of solar energy then we speak of translucence. If the Solar transmittance is given in the certificate it can be uploaded to the Certification archive and matched in the appropriate field, if the figure matches the normative data Opaque, Medium translucent, Very translucent, we can use the latter.

NOTE:
To record Solar Transmittance and Solar Reflectance in the Certification Archive, follow the procedure described on the How to upload certificates related to Solar Reflectance and Solar Transmittance page.

• After recording the Solar transmittance' we re-enter the General Data Type panel and select the File:Shade Key.png ; the Shading type panel will open.

Within this framework we can define:

• the Obscuring position

• the Type of matching glass using the glass specified in UNI EN 14501, recorded in the list.

N.B: If the field Type of matched glass is not filled in by choosing from the matched menu, the fields Ug (Thermal transmittance of glass mounted on existing window frame) and g (Solar factor of glass mounted on existing window frame) will be activated where, if known, it will be possible to specify the glass data

Job that includes Shutters and Fixtures

• Select the other type in the job order, in this case a window, to open the General data type panel and select the File:Obscuring key.png button; the Obscuring type panel will open:

In the field Matched Shutter, flush the shutter from the order types, to associate the shutter with the window and facilitate the matched glass calculation. File:Tipologiaoscurante3.png
