Each of the above environmental sections consists of a differing number of assessment issues and BREEAM credits (as described elsewhere and defined in detail in the technical sections of this scheme document).
In order to provide weightings that are adapted for local conditions, the weightings are reviewed for the first project that registers for assessment in a country or region. These weightings are then set as appropriate for that project and all other projects thereafter in that country or region for the life of the current BREEAM International version. The development of these weightings is based on robust and independent information forwarded from 'local experts' who have an understanding of local conditions. This may be a member of the design team if they can demonstrate sufficient knowledge of the environmental conditions of the region or country, or another individual or organisation with the relevant expertise.
The required information is compiled by the BREEAM Assessor using the 'BREEAM International Weightings' form (available from the BREEAM Assessor Extranet). It is the assessor's responsibility to correctly complete the 'Environmental Weightings' and submit the form to BRE Global, who use the information to develop appropriate weightings for that country or region.
The weightings are tailored based on the ten technical categories, with categories being considered 'Global' or 'Local'. Global categories are those defined as having a universal impact, independent of the local context. Local categories are those defined as being variable locally, due to social, environmental, political or economic factors. BRE Global will take account of these factors when determining the relative importance of the technical sections.
In the case of the Hea 07 Hazards and the Flood Risk criteria within Pol 03 Flood risk management and reducing surface water run-off, these issues are separately weighted from the remainder of their respective technical sections. BRE Global considers the Heath & Wellbeing and Pollution sections to be predominantly 'Global' categories; however, given the local importance of addressing natural hazards (including flood risk) these issues are 'Local'.
As well as having an impact on the weightings attributed to BREEAM sections and assessment issues (see Adaptation of weightings for local conditions above), the culture, economy, climate and work practices can also affect the development of criteria and the method of assessing certain BREEAM issues.
One example involves the opportunity for rainwater recycling in BREEAM issue .Wat 01 Water consumption. In this instance the higher performance benchmarks vary according to amount of precipitation available. The assessor can determine the precipitation zone in which the building is located using the map inFigure 4 (and other information below) and consequently use this climatic zone to establish the appropriate water consumption benchmark for a building in that location.
The map below highlights the Earth's climates zones according to the Köppen-Geiger climate classification method. They are defined according to maximum and minimum temperature ranges, as well as the total and seasonal distribution of precipitation.
For the purposes of BREEAM, the climatic zones (refer to Figure 3 ) are defined as:
For the purposes of .Wat 01 Water consumption, the precipitation zones (refer to Figure 4 ) are defined as:
