The Relationship

<p>Following the 2010 and 2011 Canterbury earthquakes, earthquake strengthening is one of the biggest issues facing heritage buildings in New Zealand. This process is mainly affecting commercial and public buildings; residential buildings are generally exempt from earthquake-prone building policies. However, some homeowners are choosing to do what is often perceived to be an expensive and time-consuming process. This research explores whether there is a heritage relationship between the homeowner and their house that motivates conservation work, such as earthquake strengthening. The central question for this research is: “What makes a heritage house a home? Is “home” a motivation for owners to earthquake strengthen their building? a case study of Dunedin”.  The relationship between homeowners and the heritage of their homes and domestic conservations practices has been underexamined in heritage studies in New Zealand. The current dissertation addresses this problem and contributes to the literature of Museum and Heritage Studies. The theoretical framework employed in this research draws on the field of Critical Heritage Studies in order to explore the relationship between ‘top-down’ and ‘bottom-up heritage’, the notion of ‘peoples-based’ heritage, the value of intangible heritage and a cycle of care. This research utilised qualitative research methods, involving the interviewing three heritage homeowners and two heritage professionals. These provided detailed findings about homeowners’ perceptions of their houses and the interaction between heritage practitioners and homeowners. The southern city of Dunedin was the case study which framed this research, because it has a rich collection of heritage buildings and a council which has been proactive in encouraging earthquake strengthening.  It was found that the heritage homeowner’s relationship with their home played a role in conservation how decisions are undertaken and that there is a lack of outreach from heritage authorities to heritage homeowners. This research provides information about the nature of the interaction between top-down and bottom-up heritage, and how this relationship can lead to positive heritage outcomes. Recommendations include developing open channels of communication between officials and homeowners, increased acknowledgement of the homeowner’s role in the conservation practice, and the establishment of a concept of Domestic Heritage to assist within the development of a cycle of care by heritage homeowners.</p>

Point Of Interest

Urban building energy modeling (UBEM) is arousing interest in building energy modeling, which requires a large building dataset as an input. Building use is a critical parameter to infer archetype buildings for UBEM. This paper presented a case study to determine building use for city-scale buildings by integrating the Geographic Information System (GIS) based point-of-interest (POI) and community boundary datasets. A total of 68,966 building footprints, 281,767 POI data, and 3367 community boundaries were collected for Changsha, China. The primary building use was determined when a building was inside a community boundary (i.e., hospital or residential boundary) or the building contained POI data with main attributes (i.e., hotel or office building). Clustering analysis was used to divide buildings into sub-types for better energy performance evaluation. The method successfully identified building uses for 47,428 buildings among 68,966 building footprints, including 34,401 residential buildings, 1039 office buildings, 141 shopping malls, and 932 hotels. A validation process was carried out for 7895 buildings in the downtown area, which showed an overall accuracy rate of 86%. A UBEM case study for 243 office buildings in the downtown area was developed with the information identified from the POI and community boundary datasets. The proposed building use determination method can be easily applied to other cities. We will integrate the historical aerial imagery to determine the year of construction for a large scale of buildings in the future.

Abstract The translation policy model by González Núñez (2013, 475) comprises three elements, namely “translation management”, “translation practices”, and “translation beliefs”. While the first two elements of this model are straightforward and easy to study in top-down approaches, translation beliefs can relate both to policymakers and policy receivers. However, the distinction has not been clearly made in this model and the element of translation beliefs has been chiefly treated in the literature as though it comes from the top levels of policymaking, hence overlooking the bottom-up aspects of it (see González Núñez 2014, 2016; Li et al. 2017). In order to improve this model, the present paper draws on the audience reception theory (Hall 1973), and shows that the current translation policy model requires a fourth element that I would call ‘translation reception’. The paper draws on the findings of a reception-oriented case study on translation policies in provincial broadcasting in Iran. This study argues that a more inclusive model of translation policy should not only include the authority-level elements of translation management, translation practices, and translation beliefs, but also the element of translation reception on the part of policy receivers. This way, I hope, the end users’ involvement in and contribution to the translation policy network will not be overlooked in subsequent research.

Purpose This study aims to explore the principles and practices for managing records with the lens of functional analysis and knowledge management by using a case study that focuses on the experience of implementing records management at a public high school in Hong Kong. Design/methodology/approach A single case study is chosen as the research method for this paper. A series of qualitative interviews and documentary analysis were used to collect and triangulate the qualitative data. Findings The results show that the case school adopted a hybrid top-down and bottom-up approach to record management, facilitate decision-making and manage knowledge. The school adopted the taxonomy provided by the quality assurance framework as the functional classification in a digital archive in the records management system. Practical implications This study provides a set of taxonomy and a hybrid top-down and bottom-up approach to schools for ensuring that accurate information of all school activities is kept and can facilitate an effective and evidence-based, decision-making process. Social implications Identifying taxonomy and management practices for effective documentation in public schools can support planning, assist with organising the continuity of improvement plans and increase reporting and accountability to society. Originality/value This study offers a taxonomy and management approach to the literature of records management and the practices for promoting and improving records management in school.

A Priority

The energy performance of an existing building is the amount of energy consumed to meet various needs associated with the standardized use of a building and is reflected in one or more indicators known as Building Energy Performance Indicators (EnPIs). These indicators are distributed amongst six main factors influencing energy consumption: climate, building envelope, building services and energy systems, building operation and maintenance, occupants' activities and behaviour, and indoor environmental quality. Any improvement made to either the existing structure or the physical and operational upgrade of a building system that enhances energy performance is considered an energy efficiency retrofit. The main goal of this research is to support the implementation of multifamily residential building energy retrofits through expert knowledge consensus on EnPIs for energy efficiency retrofit planning. The research methodology consists of a comprehensive literature review which has identified 35 EnPIs for assessing performance of existing residential buildings, followed by a ranking questionnaire survey of experts in the built-environment to arrive at a priority listing of indicators based on mean rank. This was followed by concordance analysis and measure of standard deviation. A total of 280 experts were contacted globally for the survey, and 106 completed responses were received resulting in a 37.85% response rate. The respondents were divided into two groups for analysis: academician/researchers and industry practitioners. The primary outcome of the research is a priority listing of EnPIs based on the quantitative data from the knowledge-base of experts from these two groups. It is the outcome of their perceptions of retrofitting factors and corresponding indicators. A retrofit strategy consists of five phases for retrofitting planning in which the second phase comprises an energy audit and performance assessment and diagnostics. This research substantiates the performance assessment process through the identification of EnPIs.

New Applications

A practitioner’s approach to integrate databases and evolve them so as to support new database applications is presented. The approach consists of a joint bottom-up and top-down methodology; the bottom-up approach is taken to integrate existing database using standard schema integration techniques (B-Schema), the top-down approach is used to develop a database schema for the new applications (T-Schema). The T-Schema uses a joint functional-data analysis. The B-schema is evolved by comparing it with the generated T-schema. This facilitates an evolutionary approach to integrate existing databases to support new applications as and when needed. The mutual completeness check of the T-Schema against B-Schema derive the schema modification steps to be performed on B-Schema to meet the requirements of the new database applications. A case study is presented to illustrate the methodology.

Purpose The purpose of this paper is to analyze energy performance of the multi-storey buildings built in the city of Tlemcen between 1872 and 2016. Design/methodology/approach A diagnosis based on a bottom-up methodology, using statistical techniques and engineering, has been developed and applied. To do this, demand condition analysis was conducted using a data collection survey on a sample of 100 case studies. Physical characteristics of the buildings have been determined through the archetype by period. This serves to define the strengths and weaknesses of buildings as energy consumers. Findings The obtained results showed that dwellings built between 1872 and 1920 offer better energy performance with a consumption index close to 130kWh/m2/year and this compared to the five periods considered. For dwellings built between 1974 and 1989, energy consumption is higher with an index approaching 300kWh/m2/year, thus qualifying the buildings of this period as energy intensive. Originality/value A database is established to collect physical information on the existing housing stock and thus allow their classification vis-à-vis of the energy label. This study is part of a research project aimed at evaluating and determining optimal measures for energy rehabilitation of multi-family buildings in Tlemcen. Thermal rehabilitation solutions are proposed using thermal simulations, in the following studies, to improve thermal performance of existing buildings. This study constitutes the first step of a roadmap applicable to other cities constituting climatic zones in Algeria. This helps to enrich the Algerian thermal regulation in thermal rehabilitation of existing residential buildings and conception of new ones, in urban areas with a similar climate.
