“…By changing steel frame to UPVS and timber frames, the carbon emission produced reduces by 50%, and their contribution on carbon emission of the construction phase of scenarios 2 and 3 are less than 0.5%. This proved that natural and local building materials are more sustainable and produce fewer carbon emissions than conventional and alternative materials [22].…”

This study evaluated the life cycle carbon emissions of the two most common affordable housing designs primarily used in South Africa. It examined the impact of conventional, alternative and green building materials on life cycle carbon emissions of five main building components: building envelope, internal walls, flooring, windows, and roof systems. The EDGE application modelling software was used to estimate the life cycle carbon emissions of the various building materials and the overall houses. The comparison between the resulting carbon emissions of the three scenarios proved that modifying the building materials from conventional to alternative and green materials is able to reduce ~55% and ~75% of carbon emission of the construction phase, respectively and overall ~10% of life cycle carbon emission of the house. The findings, however, indicated that a change in building material has a more significant impact on the carbon emission in the construction phase than the operational phase. The results, therefore, confirmed the critical role of material selection in affordable housing as the main contributor to the life cycle carbon emissions, given the absence of heating and cooling systems in these housing types. Finally, the finding led to the conclusion that a change in material used for affordable housing alters the method of construction for the proposed materials and consequently lowers the lifecycle carbon emissions produced by the construction industry and improves the sustainability of houses and the housing sector in general.

“…This terminology allowed Elkington to tailor the traditional sustainability 'model' more towards companies and organizations. This enabled them to measure their success not just by their financial indicators, but also by their social and environmental IOP Publishing doi:10.1088/1755-1315/1101/6/062018 3 performance and impact, thus allowing companies to communicate their ethical practices more transparently to key stakeholders [1].

This research examined the concept of industry 4.0 technologies (IT4) and identified the effects that they have on the environmental sustainability of commercial properties in South African. The extensive literature review revealed that IT4 used to reduce the energy consumption of commercial properties is not widely adopted in South Africa. This could be attributed to South Africa’s energy building regulation, SANS 204, which provides the minimum energy saving specifications for local building requirements. It was discovered that only green buildings implemented industry 4.0 energy-saving technologies to reduce their energy consumption above the SANS 204 standards. Furthermore, it was found that buildings waste large amounts of energy which can be prevented through the use of industry 4.0 energy-saving technologies. The researchers attempted to evaluate the impact of IT4 on the energy consumption of South African commercial properties through an overarching constructivist paradigm. The research was conducted using a multi-case study approach, utilising qualitative and quantitative data on green buildings which have IT4 installed. Descriptive statistics was used to analyse the quantitative data (energy consumption), while qualitative data was collected through semi-structured interviews for an in-depth analysis. The research findings revealed that IT4 could reduce a commercial building’s energy consumption by as much as 23%. The study also found that IT4 reduced a building’s carbon footprint and improved employee productivity. This paper would provide value to developers and landlords who have limited information regarding the factors around the implementation of IT4.

“…When considering "Price-to-income ratio" as an affordability indicator (see Section 2.6), Africa has the highest ratio (Supplementary Figure S1B), Asia is second, followed by America, Europe, and Oceania (Supplementary Figure S1C). (Sims and Fattah, 2016;Adamovic, 2023) However, careful selection and use of appropriate technologies and materials, and a reduction in transportation costs could contribute to overcoming these challenges (Weerasinghe and Ramachandra, 2020;Moghayedi et al, 2022). Due to their environmental and economic benefits, developed countries are reviving vernacular building materials and techniques, including earth.…”

As a response to rising housing prices and the high cost of materials in the building and construction industry, a rural prototype house (the Ecofordable House) was built with alternative technologies. The house is located in the western desert zone of Giza, Egypt, and features enhanced vernacular technologies with local materials. Interlocking compressed stabilized earth brick walls, partially reinforced, jack arch and funicular shell roofs, and date palm midribs were employed in an attempt to reduce the usage of steel, fired bricks, cement, and imported wood. The present research evaluates the house’s construction cost-effectiveness and affordability through detailed real-world data and comparisons of material quantities, labor, and costs with those of conventional methods. The “price-to-income ratio” is used as an indicator of affordability. According to the findings, walls cut costs by half, roofs by a quarter, and midribs by two-thirds; the alternatives combined saved 45%, and the house saved a quarter of the cost after adding common expenses. Moreover, less than one-third of steel, fired bricks, and cement were utilized. In the Egyptian context of government-built houses, the prototype would be affordable for most Egyptian income brackets while the conventional house was expensive for the lowest three. The findings provide empirical support for the economic advantages of enhanced vernacular technologies as alternatives and address residential affordability in similar contexts.
