    A new method for UV-irradiated degradation of nitrobenzene by titania photocatalysts was proposed, titania nanoparticles were coated on a quartz tube through the introduction of tetraethyl orthosilicate into the matrix. The dependence of nitrobenzene photodegradation on pH, temperature, concentration, and air feeding was discussed, and the physical properties such as the activation energy, entropy, enthalpy, adsorption constant, and rate constant were acquired by conducting the reactions in a variety of experimental conditions. The optimum efficiency of the photodegradation with the nitrobenzene residue as low as 8.8% was achieved according to the experimental conditions indicated. The photodegradation pathways were also investigated through HPLC, GC/MS, ion chromatography (IC), and chemical oxygen demand (COD) analyses

    ABSTRACT The International Organization for Standardization officially issued ISO 21930 and ISO 15686 standards in 2006, for quantitatively measuring the influence of buildings on environmental performance. SBTOOL is an international assessment tool promoted by the iiSBE, which can be employed to reflect the influence of the different phases of the life cycle of a building on climate, society and economy. Taiwan has been actively implementing the Sustainable Development Policy, and the Architecture and Building Research Institute of Ministry of The Interior has established the " Gr e e n B u i l d i n g E v a l u a t i o n a n d L a b e l l i n g S y s t e m" i n 1 9 9 9 t o p r o mo t e t h e s o -called Green Building. This research takes SBTOOL which is a prevailing sustainable building assessment tool adopted all over the world as the subject of research and carries out a comprehensive analysis on the development trend of international sustainable building.
