DA DB-HE / 1 is renewed Calculation of envelope parameters in hole transmittance
As we can already recognize from the Technical Code portal, they show us the updating of the different documents that make up all the extensive regulations and guidelines aimed at improving the applicability of the Technical Building Code - CTE.
Let us remember that these documents, prepared by the Ministry, although they are not mandatory, make up, together with the articulated text of the Code, the applicable regulatory framework.
In this case, the supporting document DA DB-HE / 1 Calculation of characteristic parameters of the envelope that we believe is of interest to the professional community.
What has been updated the DA DB-HE / 1 Calculation of characteristic parameters of the envelope.
Since it is an important point, we designate the comparison with two images. In this case the changes produced are aboutShafts and skylights> Thermal transmittance of holes.
DA DB-HE / 1: The calculation of the transmittance of holes allows to take into account the influence of the contact elements between glass or panels and frames, following the formulation of UNE EN ISO 10077.
The designated document DA DB-HE / 1 - October 2013. Thermal transmittance of holes:
Access to the Old Document of October 2013 … HERE.
The designated document DA DB-HE / 1 - January 2015. Thermal transmittance of holes:
Access to the New Document of January 2015 … HERE.
Let us remember that it is of general interest to see the article Justification of the new DB HE of the CTE. Also from the official portal you can identify the necessary documentation … HERE.
