GENERAL
Demonstrate that fewer materials are used in the final building design than in a typical
building of the same type by achieving at least one of the following initiatives:
� At least 90% of the interior floor area does not include finishes (apart from
sealant);
� At least 90% of the ceiling area does not have any ceiling systems (exposed ceilings
only); or
� Use of dual function surfaces or materials such as:
o Building Integrated Photovoltaics (BIPV) replacing traditional building
envelope materials on at least 10% of the area of the building envelope
(including roof);
o Vegetated roofs on at least 50% of the area of roof. (Plant selection should
favor native and drought-resistant species. This section of the roof must
also be accessible to building users); or
o Vegetated walls on at least 10% of the area of all interior partitions (Plant
selection should favor native and drought-resistant species).
