I'm currently looking for an existing industrial/commercial building to install impermeable render on insulation to fulfill the requirements of an exemplar building as suggested by the UKGBC. I believe our technology can produce 100% Breeam industrial points no problem.
Quoting the UKGBC "........ It should be emphasised that, although the BREEAM rating scale is based on a percentage score, it is not practically possible to achieve 100%. No buildings have yet scored more than 85% which we believe is close to a ceiling level of performance. Beyond this point credits gained in one area may make credits in another area more difficult to achieve. For example, an increased performance in the Health and Wellbeing section often makes it harder to achieve credits in the Energy section; refurbishing a building rather than building a new one could gain more credits in Land Use and Ecology and the Materials sections but this too could make Energy credits more difficult to achieve........"
I'm currently looking for a building designer who wants to make a name for himself/herself and a blue chip company with a building we can clad with RoofKrete and produce the first 100% Breeam industrial point building in the world. The reason being the two following points:
1. The well being section would not clash with the energy section because of the overall performance of an airtight super insulated envelope with MVHR.
I think you are greatly misunderstanding the basis of the BREEAM rating system and why it is so difficult to achieve a very high percentage.
Some of the points are contradictory in that if you score well on some you will find it very difficult to score highly on another. For example points are given for being near to transport facilities but then you are likely to lose points in an urban location through not being able to have natural ventilation.
A green roof will not get you many (if any) points.
BREEAM is a very broad assessment and I dont think you will get anywhere near 100%, its just too difficult not to mention expensive. For one you will probably score nil on the ecology section if its an existing building thats your 100% gone already.
Dare I suggest you talk to an assessor who will put you in the picture. The GBC are absolutely correct and even roofcrete wont change that. Sorry.
