Humidity Range

The evaluation through a set of questionnaire and field measurement with the use of climatic devices was conducted in an old residential college building with the best practice of bioclimatic design strategies, particularly on the implementation of daylighting and natural ventilation. Initially, the implementation of these strategies has a significantly positive impact on the satisfaction level of the residents. Temperature and relative humidity range that is accepted as thermally comfortable by university students are 29-30°C and 72-77%, respectively. The comfort level was successfully maintained with a good adaptation of living behaviour including the activity in the room, garment dressed, usage of room opening and electronic devices. Unfortunately, further improvements on natural daylighting are still required based on the negative feedbacks given by the majority of respondents.

Post Occupancy Evaluation (POE) by using a set of questionnaire was conducted to assess the perception and comfort level required by residents in a college building with the best practice of bioclimatic design strategies. The survey was based on a five-point Likert scale, covering various performance criteria of the building (architectural elements, thermal comfort, indoor air quality, visual comfort, acoustic comfort and landscape features). The positions of the rooms should be highly considered in implementing the improvement measures for increasing the comfort level of the room when this aspect considerably influences the satisfaction and perception levels of respondents.Keywords: bioclimatic design, Likert scale, post- occupancy evaluation (POE), residential college building. eISSN 2398-4295 © 2018.

Dayasari residential college building was designed with the internal courtyard that allows for numerous implementations of bioclimatic design strategies, especially on daylighting. The field measurement was conducted at eight unoccupied student rooms, selected as samples to represent ten scenarios and orientations that concerned with the level of radiation and penetration of sunlight. This study reveals the contribution of the internal courtyard in the residential college which allows the daylight penetration at the corridor areas and interior of the rooms through the transom over the entrance door, up to ten hours daily. Different amounts of daylight were measured in specific room scenarios to suggest on the most comfortable indoor living space. The recorded mean value for indoor varied from 37 to 286 lux, while in the corridor area 192 to 3,848 lux. However, the use of the large overhangs over the windows, wall openings in the room and trees with large canopy in the landscape setting should critically justify when the adequacy of daylight was drastically reduced in certain rooms.

The paper presents a comparative study of the climate responsive design strategies and indoor thermal performance of three vernacular houses in Guanshan Township of eastern Taiwan by building survey and instrument measurements. These houses are all about 80 years old. They are of Chinese style, Japanese style, and a mixture of both styles. All three houses are popular building types in the region. Key findings include: (1) Space buffer, thermal insulation, ground exposure, and natural ventilation are the key elements of climate responsive design strategies. (2) The climate responsive design strategies of the three buildings, while using similar building material, are not the same. They are strongly associated with the buildings’ cultural roots as well as the buildings’ use patterns. (3) The Chinese-style house is a heat rejecter. It is comfortable in spring and summer. The mixed-style house is a heat keeper. It is comfortable in winter and spring. The Japanese-style house is well-ventilated and has equal thermal comfort level at around 50% in all seasons. It is uncommon that vernacular buildings from different cultural traditions coexist in the same region. This study provides detail appraisals of their respective sustainable design strategies in hot and humid climate.

ABSTRACT: This research sought to reduce uncomfortable conditions created by extremes of heat and dryness in order to achieve well balanced indoor and outdoor climate, through the application of passive design strategies in Conference Centre located in hot dry climate of Kano Nigeria. Passive design utilizes natural sources of heating and cooling breezes. It is achieved by appropriately orientating the building on its site and carefully designing the building envelope (roof, walls, windows and floor). External features such as fountain, soft landscaping and proper site planning improves micro climate which in turn helped in achieving good passive design. The methodology employed is case study and relevant information sourced from pertinent literature and the internet was taken into consideration. Research has shown that more than40% of energy consumption in any building is used for cooling and lighting in order to achieve comfort level. In the course of the research, the building was studied to evaluate the use of passive elements that relates to passive lighting and cooling which are the main source of energy consumption such as building envelop, natural lighting, natural ventilation, Site and external spaces, building form, building orientation, wall/window shading and existing of energy source on conference centre building. Research has shown that, the design parameters obtained from field survey are the principal factors responsible for any good passive design of most public building such as conference centre building.

AbstractTetragonal ($${\hbox{L1}}_{0}$$ L1 0 ) FeNi is a promising material for high-performance rare-earth-free permanent magnets. Pure tetragonal FeNi is very difficult to synthesize due to its low chemical order–disorder transition temperature ($$\approx {593}$$ ≈ 593  K), and thus one must consider alternative non-equilibrium processing routes and alloy design strategies that make the formation of tetragonal FeNi feasible. In this paper, we investigate by density functional theory as implemented in the exact muffin-tin orbitals method whether alloying FeNi with a suitable element can have a positive impact on the phase formation and ordering properties while largely maintaining its attractive intrinsic magnetic properties. We find that small amount of non-magnetic (Al and Ti) or magnetic (Cr and Co) elements increase the order–disorder transition temperature. Adding Mo to the Co-doped system further enhances the ordering temperature while the Curie temperature is decreased only by a few degrees. Our results show that alloying is a viable route to stabilizing the ordered tetragonal phase of FeNi.

This paper introduces the new concept of “eco-fusion” through an exploratory case study project. It suggests the importance of multi-scalar practice in the broader field of eco-urbanism. This study introduces eco-fusion as a multiplexed paradigm, which is then discussed in two different development models. This paper first highlights the position of “eco” in urbanism by providing a brief account of key terms and how they relate to one another. It then points out the associations between eco-fusion and sustainable urban development. Through an exploratory case study example in China, the practical factors of eco-development are assessed. The study aims to provide a set of intermediate development stages while maintaining each spatial level’s interface in their own defined and distinguished contexts. The key objective is to consider integrating the natural and built environments, which is considered the best practice of eco-development in urbanism. This study’s findings highlight integrated methods in eco-urbanism and suggest new directions for eco-planning/eco-design strategies.

The building that houses the Mirvac School of Sustainable Development at Bond University is the first educational building to achieve a six Green Star rating from the Green Building Council of Australia. It has won numerous awards since opening in August 2008 including being judged the RICS (Royal Institution of Chartered Surveyors) Sustainable Building of 2009. After more than two years in use a post-occupancy evaluation study was carried out to assess the performance of the building from the viewpoint of the users; both resident staff and transient students. Results for factors such as lighting, thermal comfort, noise and air quality. were compared to benchmarks established by the Usable Buildings Trust. The evaluation also assessed the occupants’ perceptions of the building’s impact on their own productivity. Users generally find the building provides a comfortable work environment although a number of areas of performance were noted as posing some concerns. These included intrusive noise in some parts of the building and some issues with glare in daylit teaching spaces. Such concerns were found to be in accord with the results of previous studies and they highlight some recurrent problems in “green” buildings designed to maximise the use of natural ventilation and natural light. These design challenges and how occupant satisfaction is to be measured and benchmarked are also discussed in the context of this comparative building study.

This study assessed the performance of 32 village unit co-operatives (KUD) in Yogyakarta Special Region during 2011 to 2012. The efficiency level of the KUD were evaluated by employing the data envelopment analysis and multiple regression analysis using panel data to determine the factors affecting efficiency level. Efficiency analysis was decomposed into three dimensions to explore possible sources of inefficiency. According to Marwa and Aziakpono (2016), the first dimension was technical efficiency, which explored the overall effectiveness of transforming the productive inputs into desired outputs compared to the data-driven frontier of best practice. The second dimension was pure technical efficiency, which captured managerial efficiency in the intermediation process. The third dimension was scale efficiency, which explored whether KUD were operating in an optimal scale of operation or not. The results found that the average scores are 64%, 92%, and 68% for technical, pure technical, and scale efficiency respectively in 2011, while in 2012 the average scores are 57%, 94%, and 60% for technical, pure technical, and scale efficiency. Factors having significantly positive impact on several measures of efficiency are incentive and dummy variables (agriculture inputs and hand tractor). Accounts receivable only has positive relationship to pure technical efficiency. On the other hand, rice milling unit and electricity services have negative impact with several measures of efficiency.

This paper presents the results of aerodynamical performance research focused on maintaining the thermal comfort and increasing the energy efficiency of a typical social housing unit located in a high-density urban area. Bioclimatic design strategies are used to develop a sustainable and economic technology in existing housing clusters in Mexico City. A full-scale prototype, built on campus facilities, was used to study the flow conditions around the design. All scaled prototypes implement similar criterion. Furthermore, a scaled prototype is evaluated within a low speed wind tunnel installation. Additionally, numerical simulations were performed at transient state based on previous physical measurements and historical local climatic conditions to determine preferable modifications.
