“…A projected increase in extreme heatwave events 46 , and a projected increase in the proportion of urbanites living in Australian capital cities 47 will make the Sydneysiders further vulnerable. The higher daytime temperature in Western Sydney can be alleviated by installing material/ systems retaining higher moisture content, including green roofs 48 , more vegetated surfaces, and by using the cool materials in the urban fabric 49 .…”

Urban overheating (UO) may interact with synoptic-scale weather conditions. The association between meteorological parameters and UO has already been a subject of considerable research, however, the impact of synoptic-scale weather conditions on UO magnitude, particularly in a coastal city that is also near the desert landmass (Sydney) has never been investigated before. The present research examines the influence of synoptic-scale weather conditions on UO magnitude in Sydney by utilizing the newly developed gridded weather typing classification (GWTC). The diurnal, and seasonal variations in suburban-urban temperature contrast (ΔT) in association with synoptic-scale weather conditions, and ΔT response to synoptic air-masses during extreme heat events are investigated in three zones of Sydney. Generally, an exacerbation in UO magnitude was reported at daytime over the years, whereas the nocturnal UO magnitude was alleviated over time. The humid warm (HW), and warm (W) air-masses were found primarily responsible for exacerbated daytime UO during extreme heat events and in all other seasons, raising the mean daily maximum ΔT to 8–10.5 °C in Western Sydney, and 5–6.5 °C in inner Sydney. The dry warm (DW), and W conditions were mainly responsible for urban cooling (UC) at nighttime, bringing down the mean daily minimum ΔT to − 7.5 to − 10 °C in Western Sydney, and − 6 to − 7.5 °C in inner Sydney. The appropriate mitigation technologies can be planned based on this study to alleviate the higher daytime temperatures in the Sydney suburbs.

“…Therefore, it is imperative for building designers to direct the principles of the building sector toward ecological dimensions/valuations for design and construction patterns. In this respect, energy consumption of buildings depends mainly on what is being designed, at the phase of construction, as well as at the lifetime of house occupants [17], where the common principals of bioclimatic architecture of the buildings are that of: architectural structure, location, plot-orientation, and the exterior profile of the surrounding area [18].…”

In recent decades, the steady increase of energy consumption from building construction and operations cause atmospheric pollution and significant financial burden, mainly due to the high costs imposed from energy production. This study examines ways under which modern designs of a building can be applied on construction and domestication while following conventional methods of construction, compared to a building that has been constructed and domesticated under bioclimatic architecture. Particularly, two buildings were investigated in terms of the energy consumption incurred, being built on the same seaside area and period of construction and at adjacent plots of the same distance from sea for ease of comparison. The first building (A1) was constructed under the principles of bioclimatic architecture, being also facilitated with green and smart technologies. The second building (A2) was constructed under conventional construction techniques. The energy efficiency of both buildings was calculated by the “TEE KENAK” software, while specific parameters were recorded. Energy classifications of both buildings were valued and a proposed scenario and interventions unveiled the energy classification upgrading from A2 to A1. Our analysis revealed, as also found in the literature, that during thermal energy oscillating conditions, corresponding relative humidity stresses were observed, indicating that the vapor pressure handling should be taken into account towards comfort. The preliminary incremental cost evaluation and comparison of A1 and A2 energy upgrading under the criterion of simple payback period were critically discussed.

“…Modular housing for use in disaster areas should be able to provide the energy required by residents by utilizing elemental technologies such as solar panels, even in areas where the supply infrastructure is not available. Many previous studies [17][18][19][20] have been conducted on net zero energy buildings and energy-independent buildings utilizing passive and active designs. Wind energy systems and PV panels are actively used for zero energy buildings and the energy savings achieved using active elements have been compared and analyzed.…”

An investigation was conducted into temporary modular housing for use in disaster areas to assess the feasibility of energy independence. Flexible modular units have been proposed as a temporary housing solution in disaster areas, as they can be deployed in combination with energy units across a wide range of environments. A dynamic energy simulation was used to examine the heating/cooling requirements and the potential photovoltaic power generation of such modular housing in an East Asian climate. This was used to assess the potential for energy independence. The building performance was analyzed based on measurements of airtightness, insulation performance, and thermal bridge phenomena taken from mock-up modular housing. According to the wall assembly method, it was confirmed that the airtightness performance was poor. Further investigations explored the possibility of reducing the annual heating/cooling loads by improving the airtightness, which would contribute to greater energy independence. In general, the specific housing needs of different victim groups can easily be satisfied through the application of different modular unit combinations.
