Abstract: The lecture deals with some aspects on sustainability of the new buildings and of strengthened structures.
Buildings and infrastructure generate one third of the total CO2 emissions. In this respect, the construction industry can make a significant contribution by going consuming planning methods. The first part of the presentation is devoted to the correlation: CO2 emission – energy saving – environment preservation. The second part is dealing with the energy incorporated in main building materials and with the importance of thermal insulation, air tightness and thermal mass of the building envelope. For the strengthened structures, the calculated components of sustainability like total cost of rehabilitated solution, energy used with raw materials and consolidation time are presented in the third part of the present lecture.

Brief Biography of the Speaker: Prof. Corneliu BOB, graduated at the University "Politehnica" of Timisoara – Romania in 1961 and Ph.D. Civil Engineering in 1971 at the same University. In 1990 he became professor of R.C. Structures and Ph.D. – Scientific Coordinator at the Civil Engineering Faculty in Timisoara. From 1996 till 2004 he was the Head of the National Building Research Institute – Timisoara Branch. Professor Bob has also been very active in the Romanian Associations for Civil Engineering: National Association Engineering for Structural Analysis, Bucharest, Romanian Concrete Commission, Romanian Academy – Material Science. Member of IABSE since 1992, Prof. Bob became the member in Permanent Committee, Working Commission WC-8 and Structural Engineering Document Editorial Board.
In the last two years he has been involved, with good results, in the WSEAS activities.
Prof. Bob has had many and major contributions in the field of Structural Engineering:
(i). He participated as designer at more than 70 structures projects. In the last 15 years his attentions was paid to the design of the RC prefabricated structures: 25 structures have been projected and built up with more than 100000 m2 built surface. An important contribution of Prof. Bob in this field was in a patent concerning the "RC prefabricated structures with rigid nodes".
(ii). A very important field of work was paid to evaluation and rehabilitation of existing buildings. He participated at 75 projects of maintenance and rehabilitation of some important structures affected by seismic actions, gas explosions as well as time environmental factors. A very notable contribution is the "Model of reinforcement corrosion in RC Structures.
(iii). Prof. Bob C. has published 21 books and 250 papers in Journals and Proceedings of National and International Meetings. The field of interest of works is: rehabilitation of structures, analysis and design of structures, durability of buildings, new special concrete types.
Prof. Corneliu BOB played an important role in development of assessing of existing structures and in design of new buildings and he has devoted great energy in promoting the role of students and young engineers as designers and researchers.
