Similar awareness doesn’t yet exist for people looking to buy a new home, but do changes in the automotive industry hint at a different future in construction? A 2014 edition of Audi Magazine, the customer magazinestomer of Audi UK, carried an article about fuel performance and carbon dioxide emissions figures for cars. As well as describing how the tests are carried out, there was also an explanation of the usefulness of the results. It made for interesting reading, not least because of the openness with which it talked about how little relevance the test figures had for what would be achieved on the road. The other striking thing about the piece was how much resemblance its content bore to the construction industry. Controlled Conditions Tests must be “in strict adherence with European guidelines” and have to be done in laboratory conditions because the “infinite variations” in road conditions, weather and driving style would make it impossible to test one vehicle against another in the real world. The in-situ testing of construction is almost non-existent, with assessment being based around software, paperwork and the limited policing of translating design intent to site. Statements such as, “it is not practical to test every new car” brought to mind building regulations that allow acoustic or air pressure testing of a sample of dwelling types. In explaining how the figures are “for guidance only” - but that they allow for a comparison between models from one manufacturer or different manufacturers - it was impossible not to think of SAP and SBEM calculations being used to assess building compliance, and Energy Performance Certificates rating performance without accounting for occupant behaviour. Uncovering Truth Of course, not long after the article’s publication, the Volkswagen Group became engulfed in a scandal of its own making through the revelations that it cheated emissions tests. With hindsight, it’s easy to be sceptical about any apparent good intent in the magazine article because Audi is part of the VW Group. In truth, however, any car manufacturer could have written it, so the validity of comparisons between the automotive and construction industries isn’t diminished. If anything, the existence of an even bigger performance gap between a car’s lab results and road performance only serves to make the comparisons more relevant. The reality of building performance is that energy use is typically 30% higher once constructed than was predicted at design stage. That is far too big a discrepancy to be explained away by ‘infinite variations’ of occupant behaviour, or site location and weather conditions. Strength of Feeling Once the full extent of the VW scandal became clear, it was not uncommon to hear suggestions that the performance of buildings - and housing specifically - should be highlighted as a similar scandal in an effort to raise public awareness. How outraged were people really, though? In 2016, the VW Group became the number one car manufacturer in the world in terms of sales. 24 24

And because this is a magazine about insulation and construction, another question is: could a similar fate befall buildings that don’t deliver their designed performance? 25 25
