Objectives : Rainwater harvesting (RWH) is one of the most promising alternative water sources, since rainwater can easily be collected and used without significant treatment for non-potable purposes. However, the economical viability of these systems is not always assured. The objective of this study is to assess the potential water saving and financial performance of an RWH systems for a typical multifunctional building (with a rooftop area of 2,725 m2) in Guangzhou, China.Methods : The water saving and economic feasibility of the RWH system were examined using a yield after supply model for fourteen rainwater tank schemes (from 1 m3 to 30 m3).Results and Discussion : According to the simulation results, an annual potable water saving of 3,923.56 m3 can be achieved and a corresponding annual revenue of 11,496.04 CNY can be obtained from the RWH system. The economic viability expressed by benefit cost ratio is 1.50 and by payback periods are within 6.26 year, respectively. Sensitivity analysis indicates that the water price is the most important factor affecting the economic viability of an RWH systems. The widespread implementation of rainwater harvesting systems in the public buildings will not only lead to economic savings, but also go further to relive pressure on urban drainage systems and natural water body. Therefore, the actual benefits achieved by a RWH system will be greater than we predicted in current study.Conclusions : These results demonstrating that the application of RWH system is a very promising adaptation strategy for coping with the water crisis and climate change in urban areas of southern China.

In this study different water saving measures (structural and non-structural) were implemented in different urban buildings. A monitoring program of water consumption was carried out to verify and compare the effectiveness of high-efficiency plumbing fixtures and educational programs in different types of buildings (two residential houses, two Middle Schools and two Sport Centres) located in a drought experienced region (Sicily, Italy). In all cases, relevant water conservation percentages were achieved with prominent values in public buildings. The highest water conservation (up to 60%) was observed in two Middle Schools, where a large amount of water was wasted. Overall, the structural measures led to high water conservation, while the educational programs did not always improve the water saving effectiveness. These results highlight that in some urban areas the awareness of water conservation is not well established and large volumes of water are wasted, especially in public buildings, due to faulty plumbing fixtures. Governments and Environmental Agencies should promote with more effort water saving measures in order to support green building policy and global sustainability.

A set of more than 30 tetradrachmas from the second half of the 3rd century AD was discovered in Alexandria in Egypt, at the Kom el-Dikka site excavated by a Polish mission, in a zone of public buildings constructed in the 4th century AD. A row of lime kilns from the construction site of this complex stood on top of the ruins of an early Roman domestic quarter and, after they ceased to be used, were covered with earth and rubble, the latter partly from the destruction layer of these houses. Excavation of the kilns in 2008 and 2009 produced large quantities of 4th and 5th century pottery as well as pieces of marble revetment that had been fed to the kilns, and isolated late Roman coins. The tetradrachmas from two of the kilns (Fc and Fd), which were hoarded apparently in AD 293–295, seems to have preceded the destruction of the early Roman houses and may have been hidden in one of them.
