On a test building having a floor area of 100 m² and a test room with a floor area changing from 10 to 50 m², the effect of the size of windows and Trombe walls on heating, cooling, and total energy needs of the room have been analysed by the help of the computer program named "SUNCODE". Computer simulations are carried out and optimum values for energy demand are obtained and tables are prepared.

Naturally ventilated Double Skin Facades (DSF) are increasingly being employed in an attempt to minimise overall building energy consumption, primarily in temperate climates. As a direct result of higher humidity, little information is available that justifies the use of these DSF’s in hot and humid climates. This parametric study, which is based on a previous work on potential for reducing cooling loads through architectural design and mixed-mode systems for medium and high-rise office buildings, explores the potential for reducing cooling loads through facade and glass types for high-rise office buildings in a subtropical climatic region. Different glass types and a double skin facade including various opening modes form the control variables. TAS Building Simulator module of TAS Building Design software is the tool of the study.

The model is capable of numerous geometrical configurations for a single balcony situated in the centre of a street canyon. The geometry of the balcony and the street can be altered for width, length and height. The surface absorption properties of the balcony and street surfaces can be configured for numerous scenarios. The model was used to calculate for three different geometrical and acoustic absorption characteristics for a balcony. The calculated results are presented in this paper.

This paper reports a computational fluid dynamics study to investigate the effect of building wall arrangements on the amount of wind-induced ventilation through a refuge floor which is located at the building mid-height. The refuge floor analyzed has a large service core at its centre and is surrounded by exterior building walls, which are arranged in nine configurations that represent varying degrees of opening to wind flow. Results of computed flow patterns show that the wind-induced natural ventilation rate of a refuge floor varies significantly depending on the number of enclosing external walls and the incidence wind angle. A refuge floor, having only one side open, results in the worst natural ventilation and is not recommended.

Entwistle states, ‘What we learn depends on how we learn, and why we have to learn it. ’ Therefore, there is a need to address the accumulating evidence that highlights the effects of learning environments on the quality of student learning when considering colour education. It is necessary to embrace the contextual demands while ensuring that the student knowledge of colour and the joy of discovering its characteristics in practice are enhanced. Institutional policy is forcing educators to re-evaluate traditional studio’s effectiveness and the intensive 'hands-on ' interactive approach that is embedded in such an approach. As curriculum development involves not only theory and project work, the classroom culture and physical environment also need to be addressed. The increase in student numbers impacting the number of academic staff/student ratio, availability of teaching support as well as i...

The study is unique owing to its high-altitude site (2465 m) in a remote area, harsh climate (with almost no data available), and functional restrictions of astronomical facilities. The design is thermally evaluated through different modes of application of insulation, materials, types of glazing, window/wall ratios, Trombe walls, winter night insulation, summer ventilation and shading. 1.

In order to ascertain the impact of colour on how we interpret the world in day to day situations, the current study records participant responses to achromatic scenes of the built environment prior to viewing the same scene in colour. A number of environments were photographed in colour or copied from design books; and copies of the images saved as both colour and black/grey/white. An overview of the study will be introduced by firstly providing examples of studies which have linked colour to meaning and emotions. For example, yellow is said to be connected to happiness1; or red evokes feelings of anger2 or passion. A link between colour and the way we understand and/or feel is established however, there is a further need for knowledge of col...

Vernacular Vietnamese housing uses natural systems to create a built environment that integrates well with nature. The vernacular combines site-sensitive, passive solar design, natural materials and appropriate structure to achieve harmony among nature, humans and the built environment. Unfortunately, these unique features have not been applied in contemporary Vietnamese architecture, which displays energy-intensive materials and built forms. This research is analysing how environmentally-responsive elements of vernacular architecture could be applied to modern sustainable housing in Vietnam. Elements of many types of vernacular architecture throughout the country are reviewed as precedents for future building planning and design. The paper also looks at culturally and ecologically appropriate legislative and v...

Instead design and designing are integrated with a designer’s personal philosophy, understandings and attributes, relationships with others, and the nature of the project. The project to be described in this paper explores how context can mould the experience of designing at a personal and collective level, and thereby, influence the resultant outcome. The project’s focus offered the potential to monitor how students respond to the design process in a multidisciplinary environment. The findings indicate that students and staff were enthusiastic about the opportunity to participate in a community service project and that student engagement was influenced by their expectations, individual personalities, and group dynamics. It was also demonstrated that these influences were facilitated by the learning environment and impacted on the design process. . The...

The analyzed parameters for mass-housing are spacing between the buildings, the dimensions and materials of the buildings, the geometry and its orientations, the size of windows and its orientation. Within the framework of the study, it also aimed at supplying a "guide" to the city parameters and designers. The "guide", containing samples of differant configurations of the settlement, may provide them alternatives so that they can make comparison within the samples and their designs. Each sample representing a change in a parameter gives the designer an idea how such parameters affect the heating energy demand. A mass-housing district at Ankara, capital of Turkey, is selected for the case study due to its large number of mass-housing applications and easy data collection.

A balcony constructed to a special acoustic design due to its elevation above an 8 lane motorway is selected for detailed measurements. The as-constructed balcony design includes solid parapets, side walls, ceiling shields and highly absorptive material placed on the ceiling. Road traffic noise measurements are conducted spatially using a five channel acoustic analyzer, where four microphones are located at various positions within the balcony space and one microphone placed outside the parapet at a reference position. Spatial distributions in both vertical and horizontal planes are measured. A theoretical model and prediction configuration is presented that assesses the acoustic performance of the balcony under existing traffic flow conditions. The prediction model implements a combined direct path, specular reflection path and diffuse reflection path utilizing image source and ra...

Two small groups of third year design students have been given projects focussing on incorporation of daylighting to architectural design in studios having different design themes. In association with the curriculum, the themes were Digital Tools and Sustainability. Although both studios had the topic of daylighting, the aim and methodology used were different. Digital Tool studio’s aim was to teach how to design daylighting by using a digital tool, where as, Sustainability studio aimed at using scale modelling as a tool to learn about daylighting and integrating it into design. Positive results for providing student learning success within the University context were the students’ chance to learn and practice some new skills –using a new tool for designing; integration of the tutors’ extensive research expertise to their teaching practice; and...
