Hi ,

I am writing to clarify if DSM calculation can be used for level 3 and 4 projects ,

I am aware that level 5 project should be carried on via DSM tool, however I have not come across any type information to prevent use of DSM tool for other project complexity level , the main purpose of using DSM for this complexity level of projects is to minimize building’s carbon and energy consumption status by using advance feature of DSM tool ( such as more realistic weather data; inclusion of shading bodies, evaluating results from vista variable etc..)

I assume this can simply be done by defining project complexity ( such as level 4) in the software so project will still be lodged in as level 4 but the calculation can still be performed by DSM )

I found the use and DSM and features attached this tool is more beneficial and in most of the case ,may result in fewer of compliance and better EPC rating , whereas the SBEM is more simplified and restrict most of the options that are allowed by DSM

I would be appreciated if you can advise me on this matter

Regards

Hi Blackeagle

Have a read of this (but make sure you read the whole thing because differing opinions crop up initially and a kind of consensus is eventually reached):

In short, yes you can use DSM for level 3 and 4 but with a few conditions.

1) If submitting using DSM, then the level 5 lodgement fee of £250 will apply even if the project is only level 3/4.
2) Even though the project is level 3/4 you need to set the project complexity to level 5 for displayed on the EPC so that CIBSE know to charge you the extra money If you are with some other accrediting body then this rule may differ somewhat.

Thank you Complex potential for taking time and responding to my enquiry

Yes you seem to be doing the right thing , I just want to add the following after receiving confirmation from CIBSE EPC accreditation , they also confirmed that you can lodge EPC using DSM calculation for level 3or4 projects as long as You are accredited to carry out level 3,4 and 5 assessment , so I guess if you can agree with the client by considering the cost implication , you can lodge it ( always level 5 regardless if the complexity is 4 or 3) via this route however those who are only accediated for level 3 and 4 , they can not use DSM and can not lodge it via this route, they will need to use SBEM

Once again, thank you for your cooperation
