Assessor Question:
At the moment, we are modelling windows as 1 window code per window. For example, the window below we would model this as 1 whole awning window and adjust the openabilities accordingly.
We feel that it may actually be more accurate to model this window in 3 parts; 2 openable awning windows and 1 fixed panel. We'd like to model this way for all windows/doors.
Before making this change to our modelling protocols though I just wanted to double-check that we are okay to start modelling windows this way?TechLink Response:
- The data entry protocol for windows allows for configurations like this to be included as a single window unit.
- This is deemed to achieve an effective level of accuracy while involving time efficiency in the data entry process.
- Openability percentage should be adjusted appropriately.
- The more fine grained accuracy will however be achieved by entering the three separate portions but will attract additional processing time.
- That is only the case if performance data matching is available for all the individual sections.
- Fixed and openable portions often have considerably different SHGC values due to the relative frame fraction figures.
