RETURN BRIEF Program Outline

Project Overview:

This project aims to build accommodations for 20 agriculture students at the University of Sydney's Narrabri campus. The capacity will comprise 12 twin shared rooms, shared kitchens, and other entertainment areas such as a gym and a common area for celebrations. The project will aim to meet Sustainable Development Goals 3, 9, 11, and 12 by addressing issues related to flooding, temperature change, grassfire, wind load, architectural waste, and loose soil on the site.

Key Deliverables:

• Accommodations for 20 students

• 12 twin shared rooms with arch roofs

• Shared kitchens and entertainment areas

• Sustainable materials and practices include armed earth construction, cardboard tube structure frame, straw bale insulation, solar panels, and rainwater harvesting.

Design Considerations:

To address the abovementioned concerns, the accommodations will be constructed using rammed earth construction, with cardboard tubes serving as the structural frame and straw bale insulation. Furthermore, the rooms will have arch roofs, providing resistance against wind load and grassfires. Finally, the project will incorporate sustainable materials and practices such as solar panels and rainwater harvesting in addition to the structural elements.

Rammed Earth Construction:

Rammed earth construction is a sustainable construction method that uses the earth as the primary construction material. The earth is stabilized with a reinforcing material such as straw, fibres, or cement. This technique is an effective method for addressing the loose soil on site. The form also provides thermal mass and excellent insulation properties, making it an ideal choice for the accommodation project in Narrabri.

Cardboard Tubes and Straw Bale Insulation:

Using cardboard tubes as the structural frame and straw bale as insulation will help reduce the project's carbon footprint. Cardboard tubes are lightweight, durable, and easy to transport. Straw bale insulation has excellent insulation properties and is a renewable resource. These materials are also cost-effective, which will help to keep the project within budget.

Arch Roofs:

The use of arch roofs in the accommodation project will provide resistance against wind load and grassfires. The arch shape is structurally strong and offers excellent stability. The form also allows for maximum natural light and ventilation, which will help to reduce the need for artificial lighting and cooling.

PART 2 Site information

SITE LOCALITY

Scale 1:10000

The site, The University of Sydney Plant Breeding Institute, is located inside the Narrabri Shire local government area in the North West Slopes, New South Wales. It is close to the Namoi River and the mountain valley region. It is located at the intersection of the Kamilaroi Highway and the Newell Highway.

Site 3 is chosen mainly because the area is not seriously affected by pesticide and highway noises

The Sydney Institute of Agriculture brings together agricultural research from the Sydney campus and demonstrate the theories here to contribute to the agriculture and food sectors.

During our site visit, we experience the hot and dry climate, learnt more about the soil conditions at site and and observed some of the repercussions of house damage caused by the soil. We also learned more about the lifestyle of the researchers and students that reside there, and we learned that their needs of entertainment equipments. We also learnt the watertank can be erected above or below ground, as well as solar panels that can be installed on roof or detached as solar trailer.

Temperature Range

Radiation Range

Narrabri experiences a semi-arid climate, characterized by hot summers and mild winters. Narrabri can experience significant temperature changes within a single day, particularly during certain seasons. These daily temperature fluctuations are often more noticeable in the transitional seasons of spring and autumn.

During summer, temperatures in Narrabri can soar to high levels, frequently reaching 30 to 40 degrees Celsius. The hot and dry conditions are characteristic of the semi-arid climate in the region. Winter brings milder temperatures, with average daytime highs ranging from 15 to 20 degrees Celsius.

Narrabri experiences moderate wind speeds throughout the year, with occasional gusty conditions. These gusty winds can be intermittent and can significantly affect the perceived temperature and overall comfort outdoors.

Year: 2004

Location: Paris, France

This special location enables the architects to properly control the construction of the new building while allowing the museum visitors to have a peek at the design process.

Precedent 2: Miao miao Nursery School

Name: Paper Nursery School

Year: 2014

Location: Ya'an City, Sichuan, China

Within a floor plan size of 6 meters by 21 meters, two classrooms were organized facing each other divided by a central corridor. A trussed roof composed of paper tubes and steel L-angles made it possible to create a column free interior space.

Wall construction: A wall is prefabricated and then fulled up to the selected place.

Foundation: A concrete base is casted on site with tubes pre casting in.

Truss Joints

Original truss design that helps create a structure for the hay bale to be fixed to. The part is premanufactured and molded in shape before arriving on the site. Original truss design that fixes itself to the cardbard rolls on the outer rim allowing perpendicular cardboard rolls to be attached creating a solid roof structure.

Angled Joints

Original design that fixes carboard tubes at right angles. It is a simple design that is made from two flat piecs that is easy to manufacture and assemble on site.

A borrowed design that contains many components. It is designed to fix parts at certain angles. The components are premanufactured at factory and require assembly on site.

Original design that acts as the base of the vertical pole structure. Further it is premanufactured in facture and is shaped as such for easy assembly on site.

WATER COLLECTION

Our initial idea is to build some reciprocal structure to support the rainwater-collecting membrane. The reciprocal structure refers to a structural system that utilizes the mutual support and interdependence of its components to create a stable and efficient load-bearing structure. It is a construction technique where each component relies on the support of adjacent elements, creating a reciprocal relationship among the structural members. We generate the forms in grasshopper and applied in rhino model.

After our final presentation we realized that it is hard to be applied on roof and there’s lots of difficulties to construct it, so we decided to build some timber shelter instead.

The butterfly roof's unique shape and configuration allow for an effective drainage system that efficiently handles rainwater runoff. The two sloping roof surfaces converge at a central valley or low point, ensuring proper water channelling towards designated drainage outlets.

The butterfly roof's drainage system contributes to sustainable water management practices. The system also aids in minimizing runoff and the associated pollution, as the roof acts as a natural filter, removing sediments and contaminants before the water reaches the drainage outlets.
