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.

Abstract Green concepts are important things to apply on buildings. The application of the green concept on mixed-use buildings must consider several criteria, one of which is the comfort aspect. The density of commercial buildings in Medan City causes a reduction in green open space, and even many buildings do not comply with the minimum green open space requirements on their buildings, which can support the development of this city to reduce environmental temperatures. The aim of this study is to analyze the green concept that can be applied to mixed-use buildings in urban areas. A mixed-use building design with the application of green building principles is the right choice to reduce the effects of climate. The green building concept can help reduce excess heat radiation inside and outside the building. The method used is qualitative with data collection techniques through observation. The analysis was carried out descriptively to obtain a mixed-use building model with the green building concept. The results show that land use efficiency, energy conservation, materials and water conservation can be applied to provide comfortable on buildings.

Building Characteristics

Urbanization promotes the development of human civilization but brings great challenges, such as air pollution, lack of water resources, and environmental damage, to the natural environment. Water conservation effectively alleviates the lack of water resources. Existing studies mostly focus on water conservation behavior in urban areas and overlook rural areas. This study takes rural residents in Chengdu as the research object and selects four villages to conduct empirical research and fill this research gap. A total of 165 valid questionnaires are collected after face-to-face interviews. First, descriptive analysis is used to analyze the current situation of rural residents’ water conservation behavior. Second, exploratory factor analysis and the binary logistic regression model are used to explore the relationship between building characteristics, water conservation attitudes, and water conservation behavior. The results show that (1) the rural residents’ water conservation attitude plays an important role in water conservation behavior; “environmental values” is the most significant factor, followed by “saving money and joint participation;” (2) rural building characteristics such as layout of the kitchen and shower facilities significantly affect the water conservation behavior of rural residents. Based on the analysis, several suggestions are made for building a new water-saving rural area in Chengdu, such as strengthening the publicity and education of water-saving behavior and subsidizing water-saving facilities. This research provides a theoretical basis for local government departments to formulate relevant policies and serves as a valuable reference for the protection of water resources in other rural areas.

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.

Abstract Yongding River is one of the five major river systems in Beijing. It is located to the west of Beijing. It has influenced culture along its basin. The river supports both rural and urban areas. Furthermore, it influences economic development, water conservation, and the natural environment. However, during the past few decades, due to the combined effect of increasing population and economic activities, a series of changes have led to problems such as the reduction in water volume and the exposure of the riverbed. In this study, remote sensing images were used to derive land cover maps and compare spatiotemporal changes during the past 40 years. As a result, the following data were found: forest changed least; cropland area increased to a large extent; bareland area was reduced by a maximum of 63%; surface water area in the study area was lower from 1989 to 1999 because of the excessive use of water in human activities, but it increased by 92% from 2010 to 2018 as awareness about protecting the environment arose; there was a small increase in the built-up area, but this was more planned. These results reveal that water conservancy construction, agroforestry activities, and increasing urbanization have a great impact on the surrounding environment of the Yongding River (Beijing section). This study discusses in detail how the current situation can be attributed to of human activities, policies, economic development, and ecological conservation Furthermore, it suggests improvement by strengthening the governance of the riverbed and the riverside. These results and discussion can be a reference and provide decision support for the management of southwest Beijing or similar river basins in peri-urban areas.

Social and behavioral research is crucial for securing environmental sustainability and improving human living environments. Although the majority of people now live in urban areas, we have limited empirical evidence of the anticipated behavioral response to climate change. Using empirical data on daily household residential water use and temperature, our research examines the implications of future climate conditions on water conservation behavior in 501 households within the Portland (OR) metropolitan region. We ask whether and how much change in ambient temperatures impact residential household water use, while controlling for taxlot characteristics. Based on our results, we develop a spatially explicit description about the changes in future water use for the study region using a downscaled future climate scenario. The results suggest that behavioral responses are mediated by an interaction of household structural attributes, and magnitude and temporal variability of weather parameters. These findings have implications for the way natural resource managers and planning bureaus prepare for and adapt to future consequences of climate change.
