Thesis (MBA)--Stellenbosch University, 2011. / The aim of this research study is to determine the cost gradient for Green Star SA-rated office
buildings in the Western Cape province of South Africa. Very little work has been done on this
subject, due to the fact that the „green‟ building movement is still in its infancy in South Africa. The
Green Building Council of South Africa (GBCSA) has developed a Green Star SA building rating
mechanism based on the Australian green star-rating system. This rating system provides the
building environment with an objective tool to evaluate how green a building actually is.
This report includes a review of international literature, supplemented by a case study of two
designed „green‟ buildings. The key objective was to determine if there is a cost premium to a
Green Star-rated office building in the Western Cape. The case study subjects were two office
buildings planned for an office development at Paardevlei, Somerset West in the Western Cape
province of South Africa.
The findings of this case study have confirmed first indications that South Africa, and specifically
the Western Cape, should be no different to the rest of the world and specifically the United States
and Australia when it comes to the first costs of constructing „green‟ buildings. The case study
showed that there should be no cost premium for a „green‟ building that conforms to the minimum
standard of 4 Star Green Star SA Office Version 1 and that a one to three per cent premium could
be expected for a 5 Star Green Star SA Office Version 1 rating.
It was found that the best way to calculate if a premium was paid for a „green‟ building is to
compare the cost per area of the final „green‟ product with the cost per area of the original budget.
Adding costs while adding „green‟ attributes proved to be an effective and convenient way of
arriving at a theoretical premium for a progressively „greener‟ building and thus calculating the cost
gradient for Green Star SA-rated office buildings.
The conclusion is that „green‟ attributes must be incorporated into the design at the earliest
possible stage and then managed in order to keep within the original budget with a clear goal of
which categories are to be targeted and what rating would like to be achieved, in order to achieve a
„green‟ building at no additional cost.
