• Hevacomp to OpenBuildings - A complete guide for every user

    We are mindful that for a very long time Hevacomp was (and still is) central to the work of many design engineers. More so now than ever, as dependence on such design tools has increased to take advantage of the potential efficiencies and capabilities on offer.

    So, we can certainly understand that any change to something that became core to the working day of many, may seem a daunting prospect at first.

    This post is…

  • Hevacomp PartL and XML files

    A recent SBEM update as of the 18th September has resulted in Hevacomp PartL being unable to produce XML files.

    A grace window, where both existing and new versions of SBEM could be used by energy assessors, was provided for by BRE in every previous update. No such grace window has been provided on this occasion.

    This is very unfortunate as it has directly coincided with the transition of Hevacomp to OpenBuildings. Thus, as Hevacomp…

  • Hevacomp V8i Update 6 Hot Fix

    Note that update 6.1 has been released. With the update installed it is no longer necessary to apply this hotfix.

    It has come to our attention that Update 6 was released with a v5.3 EPC generator, rather than the v5.4 EPC generator. As v5.3 has been deprecated, the software can no longer lodge EPC's.

    A new upload of Update 6 will be made available w/c 12th March 2018 and we recommend downloading and applying the modified…
