Parametric skinning of complex-graphs: an airborne textile structure test-case

The research project presented in this paper aims to extend the repertoire of architectural design and construction. To achieve this purpose, research-through-design methods are used to match a commonly desired target geometry with a realistic and efficient materialisation strategy. The proposed approach has been tested through construction of practical prototypes that eventuated in a full-scale…

Learning from the past to build tomorrow: an overview of previous prefabrication schemes Milad

The world population growth can potentially lead to a shortage of appropriate houses in many countries. It can also increase the cost of land, which will directly affect the price of houses. Given the advantages of prefabrication, this method has the potential to provide numbers of high-quality houses in a short time. However, despite many…

Prefabrication: New Zealand manufacturers of prefabricated buildings and components 2017

The New Zealand population is growing fast. In 2017 it was 4,776,500 and has a 90% probability of increasing to 5.30–7.88 million by 2068. This raises the need for more houses that can be built easily, cheaply and fast and be aligned with the contemporary needs of the growing population. This paper focuses on prefabrication…

Creating a smarter building system: Design of a prefabricated envelope system for cross laminated timber

Cross- Laminated Timber (CLT) is a contemporary engineered panelised wood product and its use in construction globally is growing due to various benefits. The aim of this research is to design, develop and create a prefabricated envelope system for mass timber construction using CLT. The research capitalises on customisable building panels as they can be…

Circular economy construction: lessons from applied experimentation

The Circular Economy (CE) poses an immense challenge to the construction sector. For the first time in the history of modern construction key stakeholders are required to consider the end-of-life pathway for building components and materials. CE principles essentially necessitate that any material is productive and without the potential to contaminate in all stages of…

Unconventional approach to housing design and construction practice in Indonesia and its challenges

Globally urban housing is moving toward a vertical high-density typology. Addressing the high-density issue in Bandung City, the local government aims to improve the sprawling unplanned-settlement by redesign the area and provide medium to high-rise development in place of sprawled landed housing. A case study of Walk-up apartment project in Tamansari, Bandung is discussed in…

Life cycle analysis of cross laminated timber in buildings: a review

Greenhouse gas (GHG) emissions have increased for the last three consecutive years in Australia, and this directly threatens our ability to meet our 2030 GHG emission reduction target under the Paris Agreement. Despite progress in reducing building-related GHG emissions, little focus has been placed on the indirect GHG emissions associated with building material manufacture, and…

Investigating design and construction opportunities for Medium Density Housing on hillsides using concrete pre-fabrication

Medium Density Housing (MDH) is one of the strategies to address problems within New Zealand’s housing situation, namely the shortage of affordable urban housing. Land shortage and/or increasing land cost, overall low productivity and high production cost in the construction sector have been identified among the main drivers of this situation. This paper addresses MDH…

Study on the thermal and visual performance due to highly reflective façade in Singapore

This study preliminarily investigates the impact of highly reflective building façade material on the thermal and visual performance of surrounding buildings in the tropics. A 9-story commercial building with curved stainless-steel façade was observed and indicated as the source of reflective glare. Field measurement was conducted on nearby a 4-story school building which is directly…

Enhancing students’ experience in real-time data collection and utilisation: A cloud-based post-occupancy evaluation app

This paper presents the process of developing and testing a cloud-based post-occupancy evaluation (POE) app to enhance students’ experience in real-time data collection and utilisation. A pilot POE study was developed and conducted as part of student class activities in a lecture theatre during an undergraduate course. Three parameters on perceived indoor conditions – temperature,…

Is new housing a health hazard?

The National Construction Code has been regularly enhanced since 2002 with an effort to reduce greenhouse gas emissions. Many aging, and very young Australians spend most of their time within their homes. Coincidently, in Australia, asthma is the leading cause of disease in children aged 0 – 14 years, accounting for 17.9% of the total…

Impact of facade design on indoor air temperature and thermal comfort in residential buildings

This study aims to investigate the impact of building façade design on indoor air temperature and thermal comfort in naturally ventilated residential buildings in tropical climate. Firstly, field experiment was carried out in residential buildings in Singapore. In each unit, indoor air temperature, relative humidity and wind speed were measured continuously for one week. The…

Longitudinal field study of thermal comfort in a low energy mixed-mode building

It is commonly assumed that high levels of occupant comfort and energy efficiency are mutually exclusive. To challenge this misconception and to demonstrate that it is possible to maintain comfort without increasing energy use, a case study was carried out in an exemplary low energy building in Australia. This study was performed under the umbrella…

Measuring the Daylight Performance of Classrooms: Can a One Point Sensor Measurement Predict the Daylight Distribution within a Space?

The New Zealand Ministry of Education (MoE) has begun measuring the light, temperature, noise and CO2 level of 21 selected schools using a single sensor. This sensor is being developed as a method for routine measurement in order to understand the performance of New Zealand’s school buildings. This study used a Climate Based Daylight Modelling…

The influence of demographic and locational factors on occupants’ perception scores for their buildings

The authors and their collaborators have surveyed the 4,662 occupants of 57 medium sized commercial and institutional buildings around the world. All were surveyed using the BUS Methodology’s standard two-page questionnaire. The overall aim of these surveys was to assess the occupants’ perceptions of a range of factors related to their performance. The objective of…

The impact of IEQ factors on people on the autism spectrum

This study is an exploratory investigation into whether differences in sensory processing impact the way people on the autism spectrum perceive the built environment, focusing on the effects of individual indoor environment quality (IEQ) factors. Adults on the autism spectrum (n=83) and neurotypical control adults (n=134) participated in an anonymous online survey and were asked…

A Pilot Study on Users’ IEQ Perceptions in a Residential Aged Care Facility in Melbourne

The aged population in Australia is expanding rapidly. To cater for the Australia’s ageing population, there is a significant increase in demand for aged care facilities over the coming decades. The indoor environmental quality (IEQ) affects users’ physical health and psychological wellbeing. However, systematic research on the relationship between users’ perceptions and IEQ of aged…

Building with timber across Australian climatic contexts: an hygrothermal analysis

This paper aims to improve understanding of timber-based envelope hygrothermal performance in relation to five different Australian climate regions, ranging from subtropical hot and humid to cool temperate and including all of the country’s major cities. A standard apartment unit is used as a case study to analyse the hygrothermal performance (expressed as thermal resistance,…

Development of a model of adaptive thermal comfort and preference for housing in Australia

In Australia, the primary mandatory building performance assessment method for new homes indirectly references the ASHRAE 55 Standard adaptive thermal comfort model, which has not been extensively tested or validated for houses in this country. Emerging evidence suggests that while an adaptive model of thermal comfort is likely to be most appropriate for specification and…
