12.1 ETTV NRB 1-1

This step gives a summary of the ETTV calculation and generates the associated report, showing a room-by-room and façade-by-façade breakdown of ETTV contributors. The value for the proposed as well as reference model are generated in this step, and the indicative value for RTTV is given, and should be considered in case the roof has skylights.
Example: A building has an ETTV of 38W/m2, and its air-conditioned spaces represent 80% of the total area, when non air-conditioned spaces represent 20% of the total area.
The second line of the report will give 12 points (number of points scored for this credit before pro-rating).
The first line of the report will give the number of points scored for this credit after pro-rating, in this case 12*80% = 9.6 points.
