This study aims to reframe the common concept of post-disaster reconstruction “building back better”, especially in the context of post-disaster housing design.

An Aceh post-tsunami housing reconstruction project is used as a case study with qualitative methodology through in-depth interviews of selected respondents.

The study findings have shown that the term “building back better” is not a familiar term for housing recipients. Whichever different personal background post-disaster survivors come from, whether they are housewife, civil servant, fisherman, university student, businessman or a professional, none have ever heard this phrase. All found it hard to understand the term. This study argues that the “building back better” concept is good in policy but not working in practice. As a result, housing recipients not only were dissatisfied with their new houses but also found that the new housing configurations profoundly altered their traditional way of life. In light of these findings, the paper argues that the concept of “building back better” needs to be reframed to take account of the cultural individual and communal needs and wants of post-disaster survivors.

This study discusses only one aspect of post-disaster reconstruction that is the design of housing reconstruction.

Results from this study provide a practical contribution for reconstruction actors especially designers, architects and planners. It helps them to reconsider the common concepts they have used for post-disaster reconstruction processes particularly in designing housing reconstruction projects.

This study focuses on the question of how tsunami survivors in Aceh reacted to the design of their new post-tsunami houses and what they had done themselves to make their homes a better and nicer place to live within their own cultural needs. This study also sought to understand what motivated the opinions the respondents had about the design of housing reconstruction after the tsunami in Aceh generally. In addition, the study investigated whether survivors knew the phrase and the credo of “building back better” in a post-disaster context.

This paper aims to design an optimum vertical axis wind turbine (VAWT) and assess its techno-economic performance for wind energy harvesting at high-speed railway in Malaysia.

This project adopted AutoCAD and ANSYS modeling tools to design and optimize the blade of the turbine. The site selected has a railway of 30 km with six stops. The vertical turbines are placed 1 m apart from each other considering the optimum tip speed ratio. The power produced and net present value had been analyzed to evaluate its techno-economic viability.

Computational fluid dynamics (CFD) analysis of National Advisory Committee for Aeronautics (NACA) 0020 blade has been carried out. For a turbine with wind speed of 50 m/s and swept area of 8 m², the power generated is 245 kW. For eight trains that operate for 19 h/day with an interval of 30 min in nonpeak hours and 15 min in peak hours, total energy generated is 66 MWh/day. The average cost saved by the train stations is RM 16.7 mil/year with battery charging capacity of 12 h/day.

Wind energy harvesting is not commonly used in Malaysia due to its low wind speed ranging from 1.5 to 4.5 m/s. Conventional wind turbine requires a minimum cut-in wind speed of 11 m/s to overcome the inertia and starts generating power. Hence, this paper proposes an optimum design of VAWT to harvest an unconventional untapped wind sources from railway. The research finding complements the alternate energy harvesting technologies which can serve as reference for countries which experienced similar geographic constraints.
