Making Modern Knowledge of Traditional Carpentry in China and Japan: Myth, Reality and Transmission

Carpentry skills were among the most important elements of building practice in premodern China and Japan, and traditional carpentry skills continue in use in both countries to the present day. Although their importance has been greatly marginalised in building practice, in both countries some master carpenters have gained public recognition. This paper compares the modernisation of traditional building knowledge in China and Japan, and the fate of carpentry knowledge as the building industry and the formal discipline of architecture evolved. It distinguishes three phases in this historical trajectory: the period during the introduction of Western architecture as a discipline, when traditional knowledge was rejected or used selectively in the construction of national histories of building; the period when modern technology took over the main building industry and traditional craftsmen had to confront the realities of new technologies of production; and the period, still unfolding today, where heritage movements are promoting the recuperation and development of traditional craft knowledge. For each country, the paper traces how the nation’s history of building was selectively fashioned into an orthodox narrative; explores the content of key early technical works (for China, the official handbook Yingzao fashi [Building standards] and the craftsman’s manual Lu Ban jing [Carpenters’ Canon], and for Japan kikujutsu [literally, “compass and ruler techniques”] books); and shows how a talented master carpenter succeeded in creating a niche for himself within the contemporary heritage culture. It concludes that differences in the cultural respect accorded to carpentry knowledge in the two countries are rooted in the contrasting status of craftsmen in the premodern era.

Development of Mangrove Ecotourism in Bandar Bakau Dumai Based on Disaster Mitigation

Natural disasters that occur in the city of Dumai such as degradation of mangrove forests, coastal abrasion and tidal flooding can be mitigated by maintaining the existence of mangrove forests. Mangrove forests have important benefits on the coast of the city of Dumai, so they need to be protected together. One of the efforts to maintain the existence of mangroves can be through the use of mitigation-based mangrove ecotourism, especially in the Bandar Bakau area of Dumai City. The data collection technique in this study used a quadratic transect and added secondary data from the relevant agencies. Based on the results of the study found 9 types of mangroves that have a role as mitigation in ecotourism locations and there are biota supporting tourism, namely 13 species of birds, 7 species of reptiles and 16 species of molluscs. To maintain the sustainability of the ecotourism area of Bandar Bakau, several disaster mitigations have been carried out for retaining cliffs (revetment), reforestation of mangroves, construction of facilities that adapt to the environment, coastal education, and outreach to the community. In addition, it is very potential to develop several other forms of mitigation such as: beach nourishment, breakwater or construction of embankments to minimize abrasion, as well as construction of diversion canals and tidal flood control gates, strengthening regulations. legislation, making land use policies, policies on flood and wave resistant building standards, policies on exploration and community economic activities, promoting local cultural wisdom of maritime communities.

A CASTLE IN A STATE OF LONG-TERM RUIN AND MEASURES AIMED AT ITS PRESERVATION

In the article, the definitions “castle in a state of long-term ruin” and “architectural revitalization” are given. A list of measures aimed at preserving architectural monuments from the standpoint of their application on castles in a state of long-term ruin is considered. The definitions characterizing permissible activities on architectural monuments specified in the Law of Ukraine “On the Protection of Cultural Heritage” and restoration State Building Standards, however, in theory and practice, much more concepts are used, since the regulated terms do not cover the entire range of possibilities for the preservation and development of architectural monuments. In their works, M. Bevz, A. Rybchynskyi, O. Plamenytska, P. Molski highlight measures for the preservation of architectural monuments. Analyzing the history of the founding of defensive castles, their further restructuring and decline, we form a definition: a castle in a state of long-term ruin is a castle, as a result of destruction during a siege or loss of its defensive functions in the 16th-17th centuries was abandoned without acquiring new owners fell and came to the state of ruin that we can observe today. Looking at conservation measures using the example of castles in a state of long-term ruin, we state the following positions: The conservation method is the main point for keeping castles in a state of long-term ruin. The restoration can only be applied fragmentarily, since a holistic restoration is akin to restoration, which is an unacceptable step, given the lack of sufficient information about the original appearance of the structure. Museumification is excellent, as a method of bringing a castle in ruins to a state suitable for an excursion visit, as well as designation, as a subspecies of museumification, accompanied by both information stands and tracing of foundations reveals the planning structure of the monument. Revitalization measures aimed at revitalizing the degraded space, and renovations, which give an authentic building a touch of novelty and emphasize the period of intervention in the monument are also important. In general, the idea of preserving the castle in a state of long-term ruin should be based on three main positions such as conservation, fragmentary restoration and revitalization, that is, preserving the authentic component and returning life to the object.

THE LEED-COMMERCIAL INTERIORS (V4) PROJECTS IN CALIFORNIA

ABSTRACT This study analyzed the Leadership in Energy and Environmental Design for Commercial Interior Certified, Silver, and Gold projects version 4.0 (LEED-CIv4) in California for the period 2015‒2020. Nonparametric tests were used to assess category and credit achievement, i.e., the difference between possible and achieved points and the correlation between associated credits. The results show that most of the credits in the location and transportation category and the indoor environmental quality categories had a high level of achievement, a few credits in the energy and atmosphere and materials and resources categories had a high level of achievement, and all of the credits in the water efficiency category had a low level of achievement. Some associated credits, such as surrounding density and quality transit, had a high level of achievement and a positive correlation, whereas other associated credits, such as life-cycle impact reduction and environmental product declarations, had a low level of achievement and a positive correlation. If LEED-CIv4 credits meet the requirements of the California Green Building Standards Code 2016 (CGBSC 2016), then these credits typically have a medium/high level of achievement. If LEED-CIv4 credits exceed the requirements of CGBSC 2016, then these credits have a low level of achievement. Therefore, to improve the next version of LEED-CI, it is necessary to improve the local green codes.

LEED-CI V3 AND V4 GOLD PROJECTS FOR OFFICE SPACES: THE DIFFERENCE BETWEEN SHANGHAI AND CALIFORNIA

ABSTRACT The Leadership in Energy and Environmental Design (LEED) rating system is currently progressing from version 3 (V3) to 4 (V4) with the aim of reducing environmental damage in the global construction sector. The LEED Commercial Interiors (LEED-CI) subsystem is widely used for office spaces, particularly in Shanghai and California. Comparing Shanghai and California in terms of LEED-CI projects can shed light on the ability of the LEED-CI subsystem to adapt to local green building standards and local environmental conditions. The aim of this study was to assess the difference between V3 and V4 LEED-CI Gold office projects using a comparison between Shanghai and California. The US Green Building Council and the Green Building Information Gateway databases were used to source LEED-CI V3 and V4 Gold office projects. The natural logarithm of the odds ratio and Fisher’s exact 2 × 2 tests with a mid p-value were used to evaluate the binary data, while the Cliff’s δ and exact Wilcoxon–Mann–Whitney tests were used to evaluate the ordinal data. The results show no difference between Shanghai and California in terms of LEED-CI V3 Gold office projects in the five main LEED-CI categories. The shift from V3 to V4 LEED-CI Gold office projects is increasing the difference between Shanghai and California in terms of the following LEED-CI categories: location and transportation, water efficiency, energy and atmosphere, and materials and resources. Therefore, as compared to V3, V4 for LEED-CI Gold office projects demonstrated greater adaptability to local green building standards and environmental conditions.

Housing Challenges in Nigeria

One of the policy goals of sustainable development is the delivery of adequate housing for Countries in the global south. This is because in many countries of the global south housing is delivered more through private mechanisms, consequently this poses challenges to adequate housing delivery for most countries of the global south and the Nigeria populace. Some of the challenges faced in providing decent and adequate housing for the people include problems of unskilled workmen, unachievable westernized building standards, housing finance, high level of urbanization, poor policy programmes, and contravention of building standards in addition to poor building materials. This chapter explores housing challenges in Nigeria. In this chapter problems of housing in Nigeria will be explored; the trajectory of the history of national housing delivery and housing policies will be presented. Also, various challenges bedeviling adequate housing delivery in Nigeria is explored and explains how the quality and quantity of housing delivered in Nigeria has affected by these challenges.

An overview of room acoustics requirements in North American, nonresidential, building standards

In the United States and elsewhere in North America, acoustics requirements for nonresidential buildings in Federal acts, codes, official standards and unofficial guidelines and rating systems tend to be voluntary, grass-roots and bottom-up instead of being mandatory, top-down or governmentally mandated. This relates to the governmental viewpoint that noise is merely a nuisance, not a health risk as viewed in other parts of the world. Existing requirements associated with noise control - whether they are related to environmental/community noise, transmission of transportation noise through the building envelope or occupant noise through the interior construction assemblies or minimizing noise from building services - are more prevalent in these standards. Requirements for good room acoustics related to sound absorption, speech intelligibility and distraction-free and comfortable interiors that promote human health and well-being are appearing in more standards and being updated to have more stringent values. Much improvement is still needed in older standards that do not have regular revision cycles and open, public, review periods. An overview of the types of room acoustics metrics used, their evolving values, advantages/disadvantages and the research behind them will be provided. Recommendations for future advancements will be offered.

ANALISIS STRUKTUR GEDUNG IRNA (INSTALASI RAWAT INAP) RUMAH SAKIT UMUM PASAMAN BARAT MENGGUNAKAN SNI BETON BERTULANG 2847:2019 DAN SNI GEMPA 1726:2019

Indonesia continues to follow the development of building standards in the world which are dynamically changing for the better and safer, both in loading regulations, planning for concrete structures, steel structures, and planning for earthquake resistance. The latest planning standard methods reviewed in this study are SNI-03-1726-2019, SNI-03-2847-2019 and RSNI-03-1727-2020 replacing SNI-03-1726-2012, SNI-03-1727-2013, and SNI-03-2847-2013. The basic difference in SNI-03-1726:2012 compared to SNI-03-1726:2019 is in the coefficients of Fa and Fv, namely the coefficient of soil sites for a long earthquake period of 1 second and in SNI-03-2847:2019 which refers to ACI 318M-14 Building Code Requirements for Structural Concrete. The results of this study found that this change in the modeling of the West Pasaman Regional General Hospital met the requirements for the SNI-03-1726-2019 earthquake design and the SNI-03-2847-2019 reinforced concrete design.

Death in worship places: Evaluating the roles of religious organisations and state governments in reducing the risks of religious disaster

The numbers of accidents and disasters resulting in injury and death of the faithful in religious buildings in many parts of the world are on the increase in recent years. Interestingly, the citizens of the countries where most of the cases are reported are overtly religious and manifest their religiosity by attending religious activities in religious buildings. This, therefore, heightens the impact of a disaster, such as where there is a religious building collapse or a stampede. The attendant social, legal and economic effects of such disasters on religious organisations, religious faithful and society thus necessitate the study. This article critically examines the roles of religious organisations and state governments in reducing the risks of avoidable disasters in religious buildings. It evaluates the reports of two instances of church building collapses in Nigeria as case studies. This article observes that many religious organisations do not have effective risk and safety policies to reduce their exposure to religious disasters. It also observes that the state is ineffective in enforcing building standards. It argues that religious organisations and the state owe a legal duty to protect the lives and guarantee the safety of the faithful against the tragedy that may occur in worship places, and where this duty is breached, and a victim suffers harm, a right to damages will accrue. It concludes that although a religious organisation may not be able to stop all such disasters, having an effective disaster risk policy can assist in reducing the occurrence of avoidable mishaps in religious buildings.

QUALITY MANAGEMENT OF CUTTING TOOLS ON HEAVY MACHINES

The work is devoted to improving the efficiency of cutting tools on heavy machines by developing a quality management system for its operation, determining rational operating regulations and developing general machine-building standards for cutting. The developed model of the tool operation control system for the first time allowed to systematically consider the structure and relationships of all components of the process. The qualimetric approach to the tool operation process made it possible to develop methods for quantitative assessment of the process quality and substantiate the structure of the preparatory information subsystem.
