The program is run by the non-profit US Green Building Council and includes a set of rating systems for everything from design to construction and operation to maintenance of homes, buildings, and neighborhoods. The numbers are similar in China and the Middle East.
Although BREEAM certification numbers may have grown marginally in those regions, it is still significantly behind the alternative. This has led some in the industry to criticize the program, as it tends to charge significantly higher fees than LEED for one-off assessments. Yet, before you think the two systems are the same, you should the know the converse relationship does not always apply.
The key philosophical difference between the two, according to the sustainability consultancy Inbuilt, is the process of certification itself. BRE then assess the report and issues the certificate if they feel it meets their requirements. LEED, on the other hand, doesn't collect the evidence, the design team does. Others are more cautious. The argument for two schemes So is the dynamic tension between two competing systems desirable?
Clearly, a one-size-fits-all assessment scheme would be difficult to achieve on a global basis. For example, water efficiency is a major issue in Dubai and Australia, but not in Scotland and nor in Wales. So different issues need to be ranked differently to match regional environment and regulations. The regional versions of both schemes flow from those antecedents. Gone are the Good, Very Good, and Excellent ratings, and in comes star ratings.
The weightings are changed so that water is the key issue, rather than energy as in the standard UK schemes. With BREEAM Bespoke, for example, the assessor can work with BRE to develop assessment criteria specially tailored to a building where it doesn't fit neatly into one of the existing schemes. LEED, however, has not been created with this level of adaptability and it is not run that way. There are also differences in the way LEED calculates credits.
They are generally linked to the US Dollar especially the energy credits , which means that if the exchange rate is unfavourable, then the building's rating could suffer.
A key change that may make LEED more exportable is the introduction of regional bonus credits. Search for:. Sources: Click to access breeamvsleed. Like this: Like Loading What is WELL? Leave a Reply Cancel reply Enter your comment here Fill in your details below or click an icon to log in:.
