CIBSE AWARDS | ENTRY DATA FULLER DISCLOSURE CIBSE pioneered the disclosure of building performance data in its awards, giving the industry a unique opportunity to compare and share. Julie Godefroy analyses figures from the 2022 entries and reveals how the process will be refined to provide even more valuable data in the 2023 Building Performance Awards CIBSEs 2022 Building Performance Champion, the Library and Study Centre at St Johns College, Oxford University L ast year, following a review of past award submissions, CIBSE introduced new data entry forms for its 2022 awards. The aim was to offer more clarity for applicants on the essential information needed, and to provide a clearer and fairer basis on which judges could assess the entries. The changes were also intended to make the awards of more value to the industry, as the building performance data can more easily contribute to the CIBSE energy database (if the entrants agree). We have reviewed this years awards to identify any improvements that could be made to the entry forms. We wanted to assess the quality of the data and identify any trends in building performance among the entries. Quality of data Last years changes introduced a quantitative data entry form, alongside the usual more qualitative and descriptive form. The data was grouped in three categories: essential; recommended, but not essential; and optional. Essential is basic information on the project, approach to in-use evaluation and disclosure, and the simplest level of information about the buildings energy use and supply systems. For projects only connected to the gas and electricity grids, this tab was enough to obtain the total energy use, but not if onsite systems were present. Recommended, but not essential is the contribution from onsite energy generation systems. In the review, this section was filled in by all entrants. Optional is information such as air permeability, the project delivery process for example, whether Soft Landings was followed, or energy performance modelling carried out breakdown into energy uses, and peak demand. All entrants completed at least some of this section, with many filling in the majority. The review of 2022 entries shows that the large majority went far beyond providing only the essential information. The new forms have also removed a lot of the ambiguity in past submissions for example, whether the declared energy use included that from onsite systems; what type of floor-area measurement was being used; and the time period covered by the data and whether it represented normal occupancy. All of these could lead to significant uncertainty when trying to get a picture of data quality and the buildings performance. The quality of data received from the majority of entries is encouraging, particularly given the effect of the pandemic on access to data and resources available. For this years awards, the following changes will, therefore, be introduced. There will be only two categories of data entries essential and optional. Most of the information previously recommended Air permeability is to become essential; this recognises its importance as a key performance parameter 16 June 2022 www.cibsejournal.com CIBSE June 22 pp16-17 BPA awards data.indd 16 27/05/2022 15:40
