Today’s lecture is about resource matters. Many buildings will produce a great amount of garbage after the completion of construction. Such garbage is actually equivalent to a waste of building resources. After this lecture, we will have a clear picture of the importance of building resources and come to know that new environmental materials will greatly change the construction industry and contribute to its growth.
Environment-friendly building materials have a wide range of usages and reliable qualities. In the meantime, it has achieved a high degree of unity in terms of its coordination with environmental survival mechanism. The environmental protection features of environmental building materials are manifested in four aspects: manufacturing, use, maintenance and recovery. Throughout the history of architecture development, concrete is the main building material in architectures, which is usually consumed in large quantities. Its performance has a vital role in the safety of a building. Environmental concrete, as the name suggests, refers to the re-use of used concrete wastes. Experiments show that, in the process of cement production, substituting limestone with reasonably calculated and processed used waste concrete will result in better cement performance. Apart from being used as the raw material for cement production, residual ingredients in the wake of grading and cleaning processes can also serve as part of “environmental regenerated concrete”. Environmental buildings must have innovations on thermal insulation layer. Moreover, adequate attentions should also be placed on their waterproofness, because water content tends to affect the environment as well as the performance of various materials.
Humans’ exploration for innovation in environmental building materials has never ceased, and this would inevitably change the development prospect of modern architecture. Hopefully, we can continue our exploration on the basis of existing research results, so that more high-quality, truly environment-friendly building materials can be applied to architecture, benefiting mankind and the environment.
Zero-energy test building in Tallinn, Estonia. Tallinn University of Technology.
The concept of a Net Zero Energy Building (NZEB), one which produces as much energy as it uses over the course of a year, recently has been evolving from research to reality. Currently, there are only a small number of highly efficient buildings that meet the criteria to be called "Net Zero". As a result of advances in construction technologies, renewable energy systems, and academic research, creating Net Zero Energy buildings is becoming more and more feasible.
One example of the new generation of zero energy office buildings is the 71-story Pearl River Tower, which opened in 2009, as the China National Tobacco Corporation headquarters. It uses both modest energy efficiency, and a big distributed renewable energy generation from both solar and wind. Designed by Skidmore Owings Merrill LLP in Guangzhou, China

The Newspaper House by Sumer Erek, a London-based Turkish-Cyprist artist.
The Newspaper House is a public art installation about "making public use of a public space using public waste. The installation forces us to look at our own waste, as individuals and collectively, through both the familiarity of the material and the sheer mass of it." People contributed their old newspapers for this exhibit. Organizations such as Metronet Rail and Project Freesheet also donated thousands of papers. A shell of a house was used to start out, and Sumer Erek built the house from the inside, using the shell as a mold

Superuse Studios' Villa Welpeloo in Rotterdam
Villa Welpeloo in Rotterdam is a villa for a couple of art and graphics lovers designed by the architects of Superuse Studios. The peculiarity of the project is its 60% use of recycled materials found within a radius of 15 km from the site.
