PurposeVernacular architecture is an architectural style of buildings that were constructed by artisanal builders who lacked formal qualifications, used local materials and had a deep understanding of local climatic needs. This approach addressed climatic, energy, materials and construction issues in a low-cost way. Building interiors were often made comfortable by using passive internal climate regulation methods, which could be key to resolving some of the current issues of the modern world.Design/methodology/approachTamil Nadu is a land full of local architecture, with Konearirajapuram settlement a thriving specimen of its vernacular architecture, as one of the original Vathima villages (planned Brahmin villages). Here the authors present an appraisal of this settlement's native architecture with its various passive design elements. A questionnaire survey was also conducted among local residents, living in both vernacular and contemporary residential buildings, to understand the quality of indoor environmental comfort in the different building types (single courtyard, multiple courtyards and multiple story houses with courtyards).FindingsThe results of this study show that energy-efficient bioclimatic design strategies of traditional buildings can be analyzed with the help of climatic data and analysis tools such as Mahoney tables and Olgyay's bioclimatic chart. The study shows that vernacular design techniques and principles conserve more energy than modern buildings. The findings suggest that practical solutions for improving contemporary residential developments can be found in traditional architectural approaches and that these approaches should be incorporated in new developments to achieve energy efficiency and a sustainable future.Research limitations/implicationsA detailed survey and the user preferences are plotted in detail in this paper; similarly, Mahoney table and its requirements are analyzed with respect to context; and the results are elaborated and justified.Originality/valueThis study analyzes an entire settlement of Konearirajapuram with 300 units of vernacular residences high in comfort even at extreme climates. Assessment is carried in both qualitative case and quantitative case. Even though there are no previous studies analyzed to identify the effectiveness of the artisanal builders of bioclimatic architecture. Hence, this study brings out the solution for current energy problems from the traditional settings, because the traditional buildings requires no active systems for indoor comfort except a fan, which is negligible in terms of energy use.

The study presents the results of typological analysis and simulation modeling analysis of traditional courtyard residential houses in the cold semi-arid climate of Iran. The purpose of the research has been to analyze and evaluate traditional passive environmental strategies and their elements to provide implications for the design of sustainable residential buildings in contemporary time. Five existing traditional courtyard houses in the city of Tabriz, Iran, are used as case-studies to analyze the typology and the solar zoning conditions and to develop simulation models. The Ecotect simulation program is used to calculate the solar gains of the buildings and to analyze the effectiveness of the natural passive systems along with native design strategies in terms of potential solar gains of main and secondary living spaces. However, in the vernacular, not only the awareness of the climatic and topological considerations is important, but also the values, rituals, and beliefs that shape the design of the dwellings need to be considered. The research is based on the hypothesis that vernacular buildings (courtyard houses) of Iran have been environmentally sustainable structures. However, an important challenge of the study has been to avoid the technological bias and to consider the cultural and social aspects and embodiment of the studied houses, as well. The study also addresses the potential shortcomings that limit the reliability of Iranian vernacular architecture at present in order to arrive at a more holistic understanding of the sustainability of the vernacular architecture in the country.

Purpose The purpose of this paper is to develop a set of affordable retrofit packages that can be applied to existing residential buildings in hot-humid regions to improve occupants’ thermal comfort and reduce energy consumption. Design/methodology/approach A critical review of relevant literature to identify passive design strategies for improving thermal comfort and reducing energy consumption in hot-humid climates with focus on the building envelope was conducted in addition to a simulation study of an existing building typology in study area. Findings There is enormous potential to reduce energy costs and improve thermal comfort through building retrofit packages which is a recent concept in developing countries, such as Nigeria. Analysing the results of the retrofit interventions using building energy simulation helped in developing affordable retrofit packages which had optimum effect in improving indoor comfort temperature to the neutral temperature specified for hot humid Nigeria and further down to 3°C less than that of the reference building used. The use of passive design strategies to retrofit the building might help homeowners reduce their annual energy consumption by up to 46.3 per cent just by improving the indoor thermal comfort. Originality/value In addition to improving thermal comfort and reducing energy consumption, this research identified affordable retrofit packages and considered its cost implications especially to low-income earners who form a larger population of Lagos, Nigeria, as this was not considered by many previous researchers.

Proposed Model

Abstract Climate-resilient buildings in Palestine can play an important role in a more sustainable residential building sector. This paper aims at evaluating the effects of adopting architectural design strategies and material technologies from vernacular architecture to create a new climate-resilient building. The paper targets single houses as these represent the majority of residential buildings in suburban and rural areas, and are similar to the vernacular architecture in size and functionality. The EDSL Tas simulation tool was used to assess the thermal performance and energy savings in the proposed model compared with traditional houses and modern typical houses, in two different climatic zones. The proposed climate-resilient house has materials and design strategies derived from vernacular architecture, in addition to the use of thermal insulation. The results show that the proposed house is more climate-resilient compared to modern houses. In cold winter and hot summer climates, the proposed model presents a total annual heating and cooling energy consumption of 59% less than typical modern houses, and 5% more than old buildings. In hot arid summer and warm winter climates, the proposed house presents a total annual heating and cooling energy consumption of 58% less than a modern typical house and 8% more than the traditional house.

Coherent Body

Purpose – The purpose of this paper is to undertake a personal, historical, analytical and interpretive investigation of the evolution of the concept of authentic leadership in educational administration/leadership over a number of decades. Design/methodology/approach – The paper includes the author's reflections on his own journey on the topic as well as an analysis of the contributions of great researchers, theorists and writers since early in the twentieth century but, especially, since the early 1960s. Findings – While there is no coherent body of literature on the development of the concept of authentic leadership, there is a general discernible trend starting with a focus on self (know thyself, to thine own self be true); to considering and defining self in relationships; to accepting that there is a moral force behind notions of self-fulfillment; to recognising that authentic leaders operate in a real post-modern (perhaps post-post modern) world of pressures, paradoxes and ethical challenges. This is often a world of standards, assessment and accountability for performance outcomes. Originality/value – The paper draws on the author's own research journey and legacy on the topic as well as the contributions of “giants in the field” who have continually pushed the envelope when exploring the topic and closely interrelated topics.

Purpose – In the digital age, constant changes in libraries inform contemporary building design. An innovative library building design is a complicated process and can be viewed as a continuous process of the use of tacit and explicit knowledge and innovative tools and approaches. Knowledge management (KM) can bring about the much needed innovation, and transform tacit knowledge to explicit knowledge. For the design of a library to be successful, it is necessary to apply KM to library building design. The purpose of this paper is to look at key change impacts, to explore how to manage knowledge in building design and to identify key design principles. Design/methodology/approach – This paper looks at key change impacts, explores how to manage knowledge in library building design and pinpoints design principles. Findings – This paper finds that KM can be vital to library building design, and it can be used in all stages: to examine the internal and external environments, transform tacit knowledge to explicit knowledge by using portals, and analyze existing and future issues and trends. When effectively used, KM will result in innovative design strategies and also will reduce the time and costs of the building design and plan processes. The main principles of library building design are flexibility, accessibility, safety and security, applicability, adaptability, efficiency, and sustainability. Practical implications – This paper provides a useful overview of how to manage knowledge in library building design and design principles. Originality/value – The views, discussions, and suggestions will be of value to improve the effectiveness of library building design.

The Relationship

PurposeThe aim of this paper is to explore the relationship between vernacular architecture and Frei Otto's work, searching for shared principles and specific singularities, and testing whether lightness and sustainability can be identified as a common goal.Design/methodology/approachThe study is focused on tents and yurts, as archetypal examples of traditional architecture, and membrane structures and gridshells, as two types of light structures developed by Frei Otto. A comparative analysis of their behavior, form, elements, types, materials and strength has been carried out.FindingsThe survey carried out shows that Frei Otto's innovative tents and gridshells were not based on form imitation of vernacular architecture, but rather on a thorough understanding of physical form-generating processes, driving specific materials to optimal form, like his experiments with soap film models to generate tensioned minimal surfaces or his experiments with hanging chain net models to generate compressive antifunicular lattice shells.Originality/valueThis paper highlights how Frei Otto's endeavor to get the maximum with the minimum, to achieve a lot from a little, is also a key target of lightness and sustainability, and an essential feature of vernacular architecture.
