While BRE made Part L 2013 SBEM data available in December 2013, this was largely for testing purposes and for software developers of SBEM interfaces such as Hevacomp. As the actual switchover date to the 2013 regulations is not until April 2014 we do not have an estimated delivery date for the relevant updates to Hevacomp as of yet. At the moment we do not know how the changes to SBEM will affect the formatting of the relevant SBEM input files and the Hevacomp code will need to be updated to incorporate these changes.
Please refer to the following website for further information: http://www.2013ncm.bre.co.uk/
At this point if you are looking to assess the impact of the new regulations then you will need to use BRE's iSBEM tool. You can download this at: http://www.2013ncm.bre.co.uk/download.jsp
It is now 1st April 2014, and the new 2013 Part L regs come into effect in 5 days on 6th April 2014.
When will the update for the new part L be available? No updates are currently shown in the support area.
While the new 2013 Reg's will indeed be coming into effect on the 6th, there is a change-over period of 1 month in which both 2013 and 2006 calculations can be used. Please see the following from The Dept. for Communities and Local Government:
"EPCs for existing non-domestic buildings that are lodged on or after 6 April 2014 should be prepared using SBEM 5.2.b. There will however be a transitional period of one month from April 6 2014 when it will be permissible to use SBEM version 4.1.e for EPC lodgements."
Meanwhile, our developers are continuing to work on the update to incorporate SBEM 5.2.b into Hevacomp. Should you need to run any Part L calculations or submit any EPC's before its release, then please use SBEM 4.1.e.

Stuart,
I am in exactly the same position as you and many others who use Hevacomp and expect the software to maintain pace with current regulation.
I'm not sure what the problem is at Bentley but given the lack of urgency and attention given to Hevacomp since they acquired the software i suspect that it is being phased out.
I am extremely frustrated having invested in software, training and certification with software that i am left with out of date software that can't be used for current projects, no confirmed date as to when an update will be issued and repeated brush off from the technical staff as if it's not their problem.
My firm is so fed up that we are looking to change software completely. The other major HVAC software providers all seem to have released Part L 2013 updates well before April.
Please note: The change over period has been increased by a further month. Information available in the stickied article, above.

Duncan,
Now the period has been extended by another month should we assume Bentley plan to delay releasing the updated Hevacomp software?
Assuming that the new extension period isn't due to BRE finding an issue with the SBEM calculation engine which might result in ourselves having to address code changes, our intention is to release the update as soon as we are able.
The one month extension only appears to apply to production of EPC's, not to Part L compliance for buildings in the design stage.
I can still only iterate that it would be prudent to keep an eye on the stickied forum post. As soon as I have any information it will be posted there.
5th June 2014 is in 3 days. The sticky article for L2 has not been updated, so I assume the update will be released.
StuartO - We do not have a release date at this time. I appreciate your frustration in this regard and we at support will endeavour to communicate any information on this matter as soon as it is made available to us.
Shane,
I'm sure you'll understand if I state I find your response commercially unacceptable.
As a business we pay substantial annual fee's for the use of design software, which we expect to be regularly updated to incorporate amendments made to the industry regulations.
With no update to part L 2013, the software is in effect not suitable for our use moving forward. We cannot be left in a position where compliance with the regulations cannot be achieved due to our software provider not implementing the required software update.
"We do not have a release date at this time" is not sufficient. We require a date when the update will be available. We would also require some form of redress against the fee's we are paying to enable us to produce the SBEM calculations via a 3rd party.
Less than 15 hours to go before the grace period ends and Bentley still cannot tell us when the software will be released! I have been lodging EPCs with the new version of SBEM using another software vendor's product since 21st May so it has nothing to do with the actual SBEM engine!
I do, however, have Hevacomp Part L projects waiting to be upgraded to Part L 2013 and some of my clients are getting understandably nervous about the uncertainty of what effect the changes will have on their designs. I have of course told them that there's nothing I can do until the software is released but they can't understand why Bentley have not provided a date. I have stated that it should be released by the latest Friday 6th June but now I'm not so sure.
Can anyone at Bentley confirm that the software will be available by tommorow?
