26th May 2009: iSBEM_v3.4.a Patch02 release
Further to the announcement regarding the correction of a couple of issues through patch01 for the v3.4.a release, we continue receiving feedback from assessors, software developers and accreditation schemes and have identified and corrected another two issues. Although they are not critical within the England and Wales framework, we believe a prompt response making available a correction for these two issues will help to avoid future confusions and for some software developers it may be an opportunity to merge patch01 and patch02 releases.
We have released patch02 for v3.4.a. The patch corrects the following:
- EPCgen/BERgen xml problem. User recommendations were not written in the XML file. They were included in the EPCgen/BERgen input files what makes them accessible in future QA processed but in previous XML files they don't appear in the structured xml data.
- In certain systems, the EPCgen.net message file was written in the root of the C drive instead of in the interface/DSM specified path (third line of the 'ini' file). This is now corrected.
None of the modifications in this patch should affect the overall results.
Important Notice:
It has come to our attention that in the previous message regarding patch01 we missed informing the modification of the HVAC system inference rule for the heating generator seasonal efficiency parameter where instead of 1989 it has been decided that 1998 is the appropriate date to default a better efficiency for boilers. This used to be 1998 in earlier versions, it changed to 1989 in a recent version and after feedback from industry and assessors a final decision to revert back to 1998 has been made. The user help shows the reasoning behind this decision. An extra of the help reads: "For boiler systems installed from 1998 onwards, a default seasonal efficiency of 0.81 is suggested by the tool (based on Statutory Instrument 1994 No. 3083), and for boiler systems installed before this period, a conservative default seasonal efficiency of 0.65 is suggested. Please note that from around 1989, the boiler industry began producing boilers with efficiencies that would have complied with the above statutory instrument".
