“…During the survey, many project managers indicated that the excess costs result mainly from the high cost of components, transportation and installation, a low turnover rate of formworks, immature technology and skills and the lack of advanced management. Generally, because of the longer initial development stage for prefabricated housing, the cost is higher than that of traditional housing, which contradicts the widespread belief that prefabricated construction reduces costs [12,13,20].…”

“…There are some barriers and challenges during the development such as slow project progress, high cost, poor quality, unreasonable design, and insufficient technology levels. Zhang et al (2014) compared the direct costs of a concrete wall panel between prefabricated housing and traditional housing, and found that the direct cost of prefabricated housing is larger than that of traditional housing, although prefabricated housing can reduce more labour costs [20]. Even in the USA, Arditi et al (2000) found that a precast concrete system did not achieve cost savings but believed that it would be more economical with the improvement of expertise and communication [21].…”

In recent years, prefabricated housing has become increasingly popular and widely promoted due to its potential to improve the construction environment, quality and productivity. To develop prefabricated housing and address housing challenges, the Chinese government is encouraging prefabricated public housing. Consequently, evaluating the environmental performance of prefabricated public housing to identify whether it is environmentally friendly and worthy of investment is urgently needed. This paper compares the costs and benefits of prefabricated public projects and traditional projects based on a questionnaire and field investigation. The paper introduces information from the collected questionnaires on the respondents and projects in Beijing; this information includes the prefabrication rate, technology application, barriers, and industrial performance. The paper also reports a cost-benefit analysis of the changing rates of construction costs and environmental benefits (energy consumption, water usage, construction waste, steel and concrete usage, dust and noise pollution) by using the ∆B/∆C ratio to show the efficiency of prefabricated housing. The results indicate that the ratio is 1.81, which exceeds 1; therefore, investment in prefabricated public housing is environmentally acceptable and efficient. This paper also discusses the efficiencies in different categories and structures with and without incentives. The results show that the costs are higher and the environmental benefits are efficient but not significant; thus, promoting prefabricated public housing is necessary.

“…There are many factors that increase the costs of PH. Some researchers have found that the costs of materials and machines increase most and that precast components cost most in the view of lifecycle cost analysis (Zhang et al, 2014a;Lu & Yuan, 2013). Other researchers found that technology, management, supply chain and design cost most and are the main reasons for cost increases in view of the internal and external environment (Monty & Barry, 2018).…”

“…However, the development of PH in China still lags behind that in developed countries and other areas owing to high initial costs, lack of incentive policies, etc. (Zhang et al, 2014a(Zhang et al, , 2014bCao et al, 2015a;Li, 2020). Wang et al (2018) found that assembly sequence plan-ning and technology can affect the quality, safety, schedule and costs of PH.…”

Prefabricated housing and cast-in-site housing are two alternatives for selection by developers and customers. The government, as the policy maker, creates incentive policies to encourage developers and customers to choose prefabricated housing. This paper aims to analyze the subsidy mechanism to theoretically confirm the subsidies’ scopes, amounts and end times through an evolutionary game model and simulation. In the game model, government subsidies affect the interactions between developers and customers in the decision-making process. The findings are as follows: 1) The developer housing subsidy can lower the housing price, while the customer housing subsidy can increase the price; 2) The government should first offer the developers a larger subsidy amount during the early development stage and then offer the customers a smaller subsidy amount later; 3) The government should determine the end time based on the proportion of developers and customers who choose prefabricated housing; 4) A higher prefabrication ratio may not always improve the development of prefabricated housing, and there is an optimal production scale that creates the best development situation. The empirical analysis shows that this model can help the government develop reasonable and optimal subsidy policies within the limit of budget to stimulate developers and customers.

“…The second and more common method is to buy a predesigned house; the clients select a dwelling from a catalogue or in a display village, which is then built at a fixed cost (Zhang et al 2014). Minor changes can be made to the new house including extra rooms, facade changes, colour changes, kitchen layout and so on, but the basis of the house remains the same (Johnson 2014).…”

This research provides an assessment tool that assists the selection process of sustainability in detached suburban housing. It investigates the implications of using different design and construction methods including architecturally designed houses, developer housing and prefabricated houses. The study simulates one example of the three types of houses that have been chosen to fulfil a real client brief on a real site on the Sunshine Coast, Queensland Australia. Criteria for sustainability assessment are formulated based on literature reviews, exemplar designs and similar research projects for which the houses can be adequately evaluated. This criterion covers aspects including energy use, materials and thermal performance. The data is collected using computer models and sustainability assessment software to compare and draw conclusions on the success of each house.Our study indicates that architecturally designed housing with prefabricated building techniques are a better alternative to generic developer style housing. Our research provides an insight into the implications of three key elements of sustainability including energy use, materials and thermal performance. Designers, builders, developers and home-buyers are given an insight into some options currently available on the housing market and how the choices made during early design stages can provide a more positive environmental impact.
