“…New Zealand is showing resilience in adopting innovations and technologies (PrefabNZ, 2013), and blockchain can positively impact the enhancement of supply chains, especially in the prefabrication industry. Blockchain's traceability function is important for supply chain partners since prefabricated construction struggles with multiple stakeholders and suppliers from local or international companies (Bell, 2009). This function also helps clients/customers with the ability to track the provenance of the materials used in their final products, improving their trust and perspective on the genuineness of resources (Casino et al, 2018).…”

Different industries are modernising their systems and introducing innovations to their management practices. However, the construction industry is recognised for its lack of technological systems on which the success of this sector is deemed to be heavily dependent. Previous studies have focused on enhancing the off-site construction supply chain. However, studies on the importance and utilisation of technology in this sub-sector are scarce, predominantly where the efficiency of off-site supply chain management is stalled as a consequence of the slow implementation of technology. Thus, this article employs an exploratory approach by providing insight into the applicability of blockchain technology in New Zealand’s off-site construction and demonstrates the benefits associated with the adoption of this technology. A literature review was used to identify stakeholders’ interrelationships in different stages of prefabrication projects. Then, a pilot interview from industry experts followed by a questionnaire survey was used to determine the involvement of stakeholders in different phases and the benefits that blockchain technology can bring to this industry. The results indicate that using blockchain as a secure information management system could improve the integration of prefabrication supply systems by producing a collaborative atmosphere amongst the organisations involved.

“…However, that same insula�on means that any systems integrated into the panel would need to be a�ached to the panel's exterior or risk poten�al reduced access for maintenance. The Industrialised Building System, or IBS, is a panelised construc�on system conceptualised by property developer Keith Clark, later developed by Architects Ivan Jariss and Roger Hay in the 1970s (Bell & Southcombe, 2012). Originally based on the American mobile home, and later refined and adapted to be�er fit a New Zealand market, the prefabricated wall, floor, and roof panels were created.…”

In 2020 New Zealand government stated that all government needs to show leadership to reduce its own emissions to demonstrate what is possible to other sectors in the New Zealand economy and agreed to establish the Carbon Neutral Government Programme (CNGP) that aims to make the government carbon neutral by 2025. The New Zealand Ministry of Education, is the second largest social property portfolio holder in New Zealand, consisting of over 33,000 classrooms spread over 2100 schools, of which a good proportion of the buildings were built in the 1950’s to 60s to thermal performance standards that are lower than the currently required levels. However many of these older buildings are solidly constructed. In response to the carbon neutral program, the Ministry of Education has commenced a carbon reduction program to upgrade its building stock. Many school buildings of this era are solidly built and rather than demolishing and replacing these classrooms, this thesis aims to develop an innovative kitset recladding solution for bringing these existing buildings to a high standard of environmental performance. All without compromising the carbon already embodied within the structure. The solution proposed is to integrate the existing technologies, prefabrication, and solar heating and ventilation systems, with a significant focus on providing low-cost heating and vastly improved ventilation capabilities to classrooms. For this research, the Nelson plan school block provides the basis for the concept to be developed acting to gauge the feasibility of such a system. The resulting design proposed is a panelised, modular, retrofit kitset system designed to facilitate off-site manufacturing, rapid installation, adaptability, and modularity. This includes the capacity for varying levels of architectural intervention within a single system. This research provides insights into how existing, established cladding systems can revitalise aging school infrastructure. All while improving the buildings by the way of low-cost heating and vastly improved ventilation capabilities for existing school buildings.

“…Offsite construction, or prefabrication, is widely praised for its potential to improve building quality and reduce construction time and cost, depending on whether economies of scale can be achieved (Burgess et al, 2013). Prefabrication is a construction process, not a product or aesthetic outcome (Bell, 2009). It is the construction of any part of a building undertaken in a location different from the final building site (Cunningham, 2011).…”

“…Prefabrication is crucial in improving the construction industry's efficiency and improving opportunities to reduce and minimise material wastage. Offsite NZ (previously Prefab NZ) indicated the potential for offsite construction to have "waste minimisation savings in the order of 2.5% of the traditional tender price" (PrefabNZ, 2014), with potentially up to 75% fewer materials used when undertaking modular construction (Bell, 2009). Panelised prefabrication is when individual walls, floors or roof parts are constructed offsite and delivered to a site to be assembled.…”

Growing demand for raw materials puts increasing pressure on the Earth’s natural resources and global supply chains. This poses a challenge both to procuring the necessary construction materials and to minimising adverse environmental effects during the process. Governments are increasingly legislating to address these issues. Regarding the construction industry, they are focusing on circular economy principles and the operational efficiencies of buildings. While these are viable solutions in the long term, in reality, industry practices and regulations are currently insufficient, and inefficiencies in our construction process are not being addressed with urgency. Designers and architects play a key role in determining the resource consumption of our built environment. Yet, few resources provide practical ways to minimise material use in the design process. This research aims to iteratively explore the possibilities in the design process for minimising excess material consumption and improving designers’ ability to make informed design decisions regarding material use. Firstly, three fundamental waste minimisation principles are selected and researched for further exploration; designing for materials optimisation, designing for offsite construction and designing to use standardised parts. Each principle is then investigated in a design iteration, focusing on how the design approach allows for material efficiencies, aiming to develop practical strategies for designers. The design iterations are undertaken at three scales, allowing them to build on the knowledge gained at each stage. A key outcome of this research is that designers need to increase engagement with the construction methodology they propose to use. If a construction methodology is known early, its limitations and constraints are more effectively implemented in the design. It is more challenging to reduce material waste by adjusting an already proposed design than using a framework to inform the process from the beginning.
