Resilient and Sustainable Housing Models against Climate Change: A Review

Sustainable Housing

Introduction

As the world grapples with the accelerating impacts of climate change, the role of housing has never been more critical. More than half of the global population now resides in urban areas, and this trend is expected to continue. These cities face enormous challenges, including climate change, economic instability, and social inequality. Housing, as the basic physical and social unit of a city, sits at the frontline of these challenges.

The review paper titled “Resilient and Sustainable Housing Models against Climate Change: A Review” (Sustainability 2023) provides a timely and comprehensive analysis of how housing models can integrate both resilience and sustainability to address climate threats. The study fills a significant gap in existing literature, which has largely treated resilience and sustainability as separate concepts in housing, by identifying and comparing concrete models that embody both principles.

The Growing Need for Resilient and Sustainable Housing

The paper begins by grounding the discussion in the fundamental human right to adequate housing, as enshrined in the Universal Declaration of Human Rights and the International Covenant on Economic, Social and Cultural Rights. Adequate housing is not just about shelter; it implies security of tenure, availability of services, affordability, habitability, and a safe location. However, climate change is seriously undermining these aspects. In 2022 alone, 32.6 million people were internally displaced due to climate-related threats such as storms and floods. Developing countries, particularly in Latin America and the Caribbean the most urbanized developing region in the world are disproportionately affected due to high socioeconomic inequality, informal settlements, and insecure land tenure.

The review highlights that housing contributes to climate change through every phase of its lifecycle: construction, use, and demolition. These processes consume land, water, energy, and raw materials while emitting greenhouse gases. Conversely, poorly designed housing exacerbates occupant vulnerability to extreme weather. Therefore, the paper argues for a shift from viewing housing as a static structure to seeing it as a dynamic component of urban systems that must adapt and transform.

This is where the concepts of urban resilience and sustainability converge. Urban resilience is defined as the measurable capacity of an urban system to maintain continuity through shocks (e.g., floods, hurricanes) and stresses (e.g., heatwaves, sea-level rise), while adapting positively and transforming toward sustainability. Sustainability in this context applies to planning, development, and construction processes that drive the protection and efficient use of natural resources, reducing environmental impacts.

Methodology: A Systematic Literature Review

To identify housing models that meet both criteria, the authors conducted a qualitative systematic literature review of scientific papers, international frameworks, and gray literature published since 2015 the year the 2030 Agenda and Sustainable Development Goals (SDG 11, which calls for inclusive, safe, resilient, and sustainable cities) were adopted. Using search engines like Scielo and Google Scholar with keywords in Spanish and English, the researchers initially identified 135 documents. After applying quality, relevance, and non-duplication criteria, they narrowed this down to 75 core academic papers, books, and international frameworks.

The review employed qualitative content analysis based on six conceptual categories: Energy, Water and Sanitization, Built Form, Resources Management, Location, and Comfort. From these categories, the authors distilled key characteristics for resilient and sustainable housing, including continuous access to energy and water, energy and water efficiency, application of building codes, use of eco-friendly or reused materials, safe land, material life cycle considerations, and adaptability. Notably, the study found that while many papers focus on resilient or sustainable cities, very few studies address both resilience and sustainability specifically in housing. This gap reinforces the value of this review.

Resilient Housing Models: Three Case Studies

The review identifies three notable resilient housing models designed primarily for Caribbean countries and Puerto Rico, regions highly exposed to hurricanes, strong winds, and floods. These models emerged from initiatives like the Resilient Homes Challenge and local architecture competitions.

  1. Resilient House Antu (Caribbean Countries, 43 m²): This model was designed based on lessons learned from Hurricanes Irma and Maria. It uses common, low-maintenance materials (wood, river stones, concrete) and costs approximately USD 9,962. While it did not incorporate energy or water efficiency measures, its resilience lies in its location on safe land and its design tailored to local capacities and terrain realities. The emphasis is on robustness and repairability using locally available skills and materials.

  2. Spirited Bamboo (Caribbean Countries, 50 m²): The winner of the Resilient Homes Challenge, this model incorporates both resilience and passive sustainability features. It uses bamboo and concrete pillars, resisting earthquakes and strong hurricane winds. It integrates solar energy for electricity, passive cooling via a double-roof system, shade, insulation, and cross-ventilation. For water, it includes rainwater harvesting for irrigation or UV-filtered drinking water. Construction cost was even lower: USD 8,107. This model demonstrates that resilience and basic sustainability can be combined at a low cost.

  3. Resilient Link House (Puerto Rico, 50 m²): This award-winning model (XVI Biennial of Architecture, Green Home of the Year) respects local building codes and addresses hurricanes, strong winds, and floods. It features a portable 1.5 kW solar power plant with battery storage, a 200-gallon rainwater cistern that works by gravity (even during power outages), and an underground greywater system. Materials include masonry and concrete panels with structural insulation. It represents a more technologically advanced resilient home.

Across these resilient housing models, several common characteristics emerge: (1) location on safe land is non-negotiable; (2) concrete is a common, durable material for structural integrity; (3) alternative water and energy sources (rainwater harvesting, solar) are prioritized; and (4) low maintenance and local construction capabilities are key considerations.

Sustainable Housing Models: Four Certified Case Studies

In contrast, the sustainable housing models reviewed are larger, higher-cost, and certified by organizations like LEED, Passive House, or Australia’s “Your Home” guide. These models focus heavily on energy efficiency, water conservation, indoor environmental quality, and material life cycles.

  1. Harmony House (Australia, 194 m²): This home produces its own electricity via a 14 kW photovoltaic system and uses passive solar design (thermal mass, cross-ventilation, strategic windows). It stores 27,000 liters of rainwater to meet all water needs, and treats domestic wastewater with a worm farm septic system chemical-free and low-maintenance. Fiber cement cladding with self-cleaning silica coating reduces maintenance.

  2. Caloundra (Australia, 150 m²): This model uses low-emissivity glass windows/doors, a 1.5 kW solar system, and energy-efficient appliances. A 5,000-liter rainwater tank supplies bathrooms, laundry, and gardens. It prioritizes low-VOC paints, thermally efficient materials, and recycled/recyclable content, aiming for disassembly at end-of-life.

  3. The Owen Residence (USA, 800 m²): A LEED Platinum-certified home and Project of the Year, it operates grid-neutral with 42 solar panels, Energy Star appliances, and returns surplus energy. It uses eight rain barrels, drought-tolerant landscaping, and a fully permeable lot to manage stormwater. Recycled and locally sourced materials are heavily used.

  4. Sapphire Passive House (Australia, 238 m²): This is the first Certified Passive House in Australia to meet the highest bushfire risk rating (BAL-FZ). It is 90% more energy efficient, using only 1.66 kW/day, supplied by a 5 kW solar system with 10 kW battery storage. A 22,000-liter rainwater tank serves all internal fittings except the kitchen tap. It also received Healthy House Australia certification.

The sustainable housing models share these features: (1) certification by a recognized body (LEED, Passive House, etc.); (2) design tailored to local climate and bushfire/flood zones; (3) extreme energy and water efficiency; (4) use of local, recycled, and low-VOC materials; and (5) attention to occupant health and comfort.

Comparative Discussion: Resilience vs. Sustainability in Practice

The discussion section synthesizes findings to highlight synergies and trade-offs. Both resilient and sustainable models prioritize location on safe land, durable materials, and continuous access to water and energy. Concrete appears in all resilient models for its durability, while sustainable models use a wider variety of certified or recycled materials.

Key differences emerge in scope and drivers. Resilient models are often post-disaster responses, smaller, lower-cost, and focused on survival and rapid recovery. They may not include energy efficiency measures (e.g., Antu House) but do include alternative supply. Sustainable models are proactive, larger, higher-investment, and focus on long-term operational efficiency, emissions reduction, and occupant well-being. However, the review notes that the most advanced models like Spirited Bamboo and Sapphire Passive House bridge both paradigms by combining solar, rainwater, passive design, and extreme weather resistance.

The paper identifies significant barriers to widespread adoption of resilient and sustainable housing. These include:

Despite these barriers, the authors argue that investing in both resilience and sustainability is not an option but a necessity. Doing so strengthens the principles of adequate housing under international law and directly supports the Sustainable Development Goals (especially SDG 11), the Paris Agreement climate objectives, and the New Urban Agenda.

Conclusion and Key Takeaways

In conclusion, this review successfully identifies and characterizes three resilient housing models and four sustainable housing models that respond to climate change. The main characteristics for achieving both goals include:

The study is particularly valuable because it moves beyond abstract definitions to concrete, costed examples. For policymakers, urban planners, and architects in developing countries, these models provide a starting point for designing housing that can withstand climate shocks while reducing environmental footprints. The authors recommend expanding similar studies to infrastructure and technology development. They also encourage professionals from social, economic, and political sciences to pursue complementary research on the enabling conditions for scaling such models.

Ultimately, resilient and sustainable housing against climate change is not merely a technical specification; it is a paradigm shift. It requires moving from siloed approaches to integrated design, from short-term costs to life-cycle value, and from housing as a commodity to housing as a human right that safeguards well-being in an uncertain climate future. This review provides a robust evidence base to guide that transition.
