Survey-Based Analysis of Water Consumption Law in High-Rise Public Buildings and Water-Saving Performance of Pressure-Reducing Measures

Facing the contradiction of water scarcity and water wastage in most cities of China, this study aims at probing into the factors influencing water-use efficiency and assessing water-saving potential by adopting pressure control measures based on field survey conducted in 23 high-rise buildings in Suqian, China and laboratory tests. Results showed that per capita water consumption (PCWC) exceeding water consumption norms is common in these buildings. The hourly water consumption variation law is quite different among different types of buildings. These differences should be considered in designing building water supply systems to lower water and energy consumption. On the basis of correlation analysis, the order of factors influencing the PCWC follows average tap water pressure, percapita building area, and building age, suggesting pressure management in high-rise buildings is a key water-saving measure. Field tests of outflow characteristics under different water pressures indicated that over-pressure outflow (OPO) is a common cause of water wastage in buildings, however, no branch pipe pressure control measures were found in all the surveyed buildings. Laboratory tests showed that branch pipe pressure-reducing measures can lower water consumption and improve the comfortability of use as well. Therefore, in addition to applying high efficiency water-saving devices, we strongly recommend that branch pipe pressure-reducing measures should be strictly implemented in designing new building water supply systems and reconstruction of existing old building water supply systems, thereby, promoting water, energy saving and development of green building.

Post-occupancy Evaluation for Ceremonial and Public Buildings： A Case Study of Amman City Hall, Jordan

POE （post-occupancy evaluation） of buildings is one of the most important mechanisms which ensures that ceremonial and public building performance including its facilities is sustained. POE studies concerned with efficiency of building performance after using and implementing with the end-user. It provides feedback on the current status of the building and proposes solutions to existing problems in addition to guidelines and design criteria for the best solutions in the future. Despite precedent research which have been undertaken in the context of building performance, aspects of evaluating building performance have not been specified and used widely in Jordan. At the commencement of this research, the concept of POE is still new in Jordan, and the local building practitioners are still unfamiliar with this approach for the evaluation of a building performance in Amman. Accordingly, there is a need to undertake this kind of research in Jordan to identify the main guidelines of POE to be applied effectively in ceremonial and public buildings. This study therefore applies POE of indoor environment of the public buildings by exploring the guidelines that can constitute a successful and effective framework for the public buildings in Amman. This was achieved using the learnt lessons from Amman City Hall building which was used as a case study and reflecting them on these where needed. Analytical and descriptive approach basis was applied, adopting a mixed method approach （qualitative and quantitative method） by using observation tool and a questionnaire survey with occupants. Context-derived data and statistics analyzed together were used to explore the guidelines of POE to be applied effectively in public buildings. A field visit and observation tool was adopted for gathering information leading to the findings and recommendations. A questionnaire was also used to extrapolate core findings of this research. This research provides a significant contribution of POE result towards improving indoor environment to ceremonial and public buildings in Jordan.

Public Building Supervisors＇ Assessment of Site Progress Record Keeping Practices in Abuja, Nigeria

The importance of good site progress records in quality assurance; tracking project progress; preparing, analyzing and resolving claims; and placing responsibilities in the event of dispute in building contracts is widely recognized. This study engaged Public Building Supervisors in the assessment of site progress record keeping practices in Abuja. A simple structured questionnaire （which mainly assessed the nature and importance of records kept, reasons for keeping them; level of satisfaction with the current approach, challenges and practical ways of improving the practice） was administrated to a hundred of the supervisors, out of which seventy one was properly completed and returned. The results show that all five site progress documents （minutes of progress meetings, day-work sheets, photographs, weekly site records and personal site diaries） found in literature, are in use in Abuja, and have at least a high importance rating （i.e., relative importance index, 0.6 〈 RII 〈 0.8）. Prominent among the reasons for keeping the records are： control of ongoing work （R11 = 0.83） data for estimating future works and terms of contract requirement （each with RII = 0.823）. Though the present record keeping practices were largely assessed satisfactory, 95% of the Supervisors still yearned for improvement. The challenges to the current practice are consistent with those identified in literature and are： continuity consistency, legibility and accountability; in descending order of frequency of occurrence. Computerization, regular inspection of progress documents by assigned supervisors and in-house training of site staff are recommended for improving the record keeping practices.

A Case Study of VäxjöMunicipality’s Actions to Increase the Construction of Wooden Multi-family Buildings

Sweden has a housing shortage,which the Swedish authorities expect to continue until 2025.Producers of wooden multi-family houses have a relatively small market share in comparison to traditional building materials.The limited capability to fulfil the increased building demand also restricts the possibilities for development towards innovation,bio-economy and sustainability.The municipalities in Sweden have responsible for planning of the building development in their region based on their projected requirements and strategies.Combining this with a desire to develop sustainable building solutions based on wood increases the complexity.Currently,public building developments are achieved through the public procurement act or the land allocation activity,dependent on their development strategy.This normally involves the development of local strategies regarding,e.g.design,material choice and geographical development.By identifying market drivers enables improved market entry activities related to public building initiatives using wood-based solutions.Hence,by improving transparency in the land allocation activity generate enhanced possibilities for the companies to respond successfully to the requests submitted by the municipalities.This knowledge is used to better understand the required strategic development for the companies,the government and the municipalities to increase the use of sustainable building materials in Swedish multi-family housing projects.

Open Building as a Design Approach for Adaptability in Chinese Public Housing

Surveys on public housing in Northern China indicated that the common aim of Chinese public housing, which is to provide affordable housing, had been mostly satisfied. However, more than one fourth (29.9%) of the public housing units that were investigated were structurally modified by their occupiers for different layouts. This situation indicated that a fixed plan could not fulfill housing occupiers’ various requirements on spacing layout, and critical awareness had been shown that the adaptability of the public housing units was always ignored. Open Building is well organized and implemented in the field of residential area to increase adaptability and sustainability of dwellings. This paper reviewed the development of residential Open Building and attempted to reveal solutions for the design of adaptability in Chinese public housing. Based on the dwelling unit types, dwelling spaces, living modes and demographic conditions of the public housing units were investigated;and concerning the actual carried out adaptations in the public housing units, this research explored two levels of design and control methods: prototyping unit for possible layouts and flexible partitions for space-function reconfiguration. By adding design values of adaptability in public housing, key aspects showing?the potentials and challenges for the design of public housing were summarized for future reference.
