[esp-r] Re: Has ESP-r finally been validated according to EN 15265 and EN 15255?

Hi Bjorn,

The quick answer is yes for the 15265, and partly for 15255.

Unfortunately, the only documentation that I am aware of for EN 15265 is at "Appendix E" of my PhD (http://strathprints.strath.ac.uk/7816/1/strathprints007816.pdf).
Do you need the documentation in a specific format or would what is inside Appendix E be enough for your purposes? I remember that we also wrote a report about that 6-7 years ago and it was formatted according to the guidelines of the Standard. However, the report never made it out to be published at ESRU's website at that time. Not sure if I still have it somewhere within my back-up files. 
As Jon mentioned the 15265 tests are also publicly available in several branches and you probably have them in your folders too (look inside the validation folder). 
I have just run Test 1 of 15265 with a generally recent version of ESP-r (6 months old) and I get exactly the same results as the ones produced 6-7 years ago and are reported in Appendix E. In other words, the results in Appendix E are probably the same as the ones you would get with the current version of ESP-r. Generating these results (for 15265) was automated at that time by pressing the validation button in Project Manager but that specific functionality for 15265 tests only was lost after a period of time, perhaps due to changes in other parts of ESP-r.

Regarding 15255, I am not aware of anyone who has managed to fully complete them and produce the relevant documents. Having said that, me and Paul Strachan did look at them in the past and we did come very close to completing them. 

Best regards,
Georgios

Hello

Has ESP-r finally been validated according to EN 15265 and EN 15255?
If yes, where do I find the documentation?

PS: Found some mails from Georgios and Gunter regarding this topic in the archive, se below, but did not find any documentation or confirmation regarding the validation.

Best regards,
Bjørn Jenssen

Dear Gunter,

I have worked on the ESP-r's modelling of the 15265 tests during the last month or so. I have completed the tests and it was necessary to develop specific code to deal with two parts of the specifications:
1) to impose global solar radiation on vertical west facing surfaces
2) to account for time shifting of all schedules (including heating and cooling setpoints) between summer and winter.

The code is only in my branch and it will probably be in the next official release of ESP-r.
However, to complete the tests I am puzzled with another point in the specifications and here is where I need your advice (or the advice of someone who is familiar with these specifications):

-I can not figure out the optical properties for ESP-r based on what I read in this Standard. There are two types of glazing (shaded double and just double) and the Standard defines transmittance, absorptance and reflectance of the window glazing components plus the g-value. However, it also says that all these solar parameters are considered as independet of the solar angle!!! I will have to use WIS or WINDOW5 to get the angular data for ESP-r but I am not sure how to interpret the specifications. Can you advise me on this (or
better: can you send me the angular data for these glazing systems)? These tests seem to be very sensitive on the type of optics used.

If I figure out the details on the optics I can make sure that the next version of ESP-r includes the required code for these tests and that ESRU will publish a report for your needs.

However, I am not aware if there is anybody working on the 15255 (the other Standard that you mention).

Regards,
Georgios
