Based on an extensive literature review on passive building designs for tropical climates, seven energy-efficient building design principles for tropical climate areas were deduced.

Cities have been built on the benefits of density, proximity, and connectivity. However, the recent COVID-19 pandemic, along with continuously evolving communication technologies, has seen an increase in vacancies and underuse of urban buildings, challenging the agglomeration benefits of cities and our understanding of business-as-usual.

The emerging demand for sustainable development and the need for efficient use of resources across the built environment have stirred research efforts globally. The construction sector is often regarded as one of the major world consumers of resources, so many international establishments are trying to create a sustainable environment through adaptive reuse of existing building stocks, a concept which has been receiving momentous recognition by reason of its richly diversified applicability for circular economy.

Rapid urbanisation and climate change are two of the major challenges of our time. People living in cities' poorest areas are agents of change both in terms of climate mitigation and adaptation.

This new publication explores the intertwining nature of circular economy, urbanisation and poverty.  It looks at how existing approaches of circularity and the informal economy can be taken up and reinforced to find solutions to these challenges.

Building with natural materials has proven to be a sustainable approach in addressing the needs of affordable and healthy housing and improving living conditions in informal settlements in an era of ecological transition. In view of this, the use of bamboo as a building material is considered a promising practice. However, although many traditional building techniques incorporate the use of bamboo, its application in contemporary informal settlements is disputed.

The informal settlements in the Global South, mostly comprising of inadequate building solutions, are growing rapidly, therefore calling for more sustainable construction interventions and upgrading strategies. Within this context, this study considers that appropriate construction strategies are capable of engaging with the local economy, affected by endemic poverty, therefore contributing to the improvement of the settlement's socio-economic and physical conditions at once.

The objective of the research was to assess the roles of municipal building authorities and their potential to act when a rapid change is needed towards energy-efficient and sustainable building and refurbishment. Our premise was that local authorities will have an essential role in improving the awareness and commitment of stakeholders and in supporting them to understand potentials of sustainable building. However, this may require the development of current roles.

Technological progress has had negative effects as well as positive effects if it affects the life industry and the entire ecosystem significantly through the great consumption of natural resources, and here the construction sector in general and the health sector, in particular, have a role in this.

Because public entities exercise large-scale purchasing power in contracts for goods, services, and construction of infrastructure, policies prioritizing environmentally and socially responsible purchasing can drive markets in the direction of sustainability. In fact, public procurement accounts for an average of 12 percent of GDP in OECD countries, and up to 30 percent of GDP in many developing countries.

As the need to stem climate change gains in urgency virtually by the day, new environmentally sensitive practices and policies targeted at limiting the global average temperature increase to 1.5°C above pre-industrial levels are essential. This is particularly relevant in the manufacturing of cement – the key ingredient in concrete. The world is in the midst of an infrastructure and building boom as new economies emerge and developed economies expand.
