Sustainable development is the core requirement that will enable our generation to safeguard the ecological, economic and social future of the generations that follow us. The building and real estate industry has a significant role to play in achieving these objectives. SIS wishes to make a decisive contribution to driving the change in this sector towards more sustainability. SIS provides a neutral platform for the exchange of information and communication between all interested parties from the worlds of business and science, the political arena as well as the general public. Our institute reaches out to companies and private individuals, associations and public institutions alike.
