What is Regenerative Architecture?

The world of architecture is called upon to respond to climate emergency, considering that 40% of global carbon emissions comes from the built environment. In response to this challenge, sustainable architecture comes into play, but often, it stops only at the concept of ‘sustaining.’ Let’s explore now a more ambitious and forward-thinking approach: ‘regenerative architecture.’

To follow this type of architecture, managing environmental resources and creating spaces that support users’ well-being, it is necessary to use a tool for energy analysis. In this regard, at the end of the article, you can find a video showing how to best use these tools.

Regenerative design and city concepts

Regenerative landscape architecture: integrating ecosystems into design

Regenerative architecture, inspired by the principles of regeneration known in biology, represents a revolutionary approach in the field of sustainable construction. These principles, originally associated with the ability to renew tissues and ecosystems in living organisms, are adopted to shape the way we design, build, and live in built environments.

The integration of natural ecosystems within built spaces is not just an aesthetic option, but a fundamental principle that reflects the evolution of our cities and lifestyles.

Regenerative architecture aims to create a harmonious dialogue between the artificial elements of the building and the surrounding natural context, improving urban quality of life and promoting environmental sustainability.

Biological Foundations of Regeneration

Biology teaches us that regeneration is the renew, restore, or growing damaged tissues processes in organisms. This concept, applied in fields such as medicine and ecology, is now at the core of regenerative architecture. In other words, it’s about adopting a biological mentality in designing the spaces we live in.

Natural World Role

What sets regenerative architecture apart is its deep involvement with the natural world. It’s not just about designing buildings that respect the surrounding environment but actively integrating natural elements into the architecture itself. Trees, plants, watercourses and other natural features become integral parts of the design process, contributing to creating harmonious and sustainable spaces.

Forward-Thinking Approach

The essence of regenerative architecture lies in a forward-thinking approach. It’s not just about solving immediate problems but understanding and anticipating long-term dynamics between the built environment and nature. This requires designing beyond the mere functionality of buildings, considering how they can contribute to restoring and maintaining natural balances.

Restoration of Environmental Processes

Regenerative architecture goes beyond passive coexistence with the environment. Rather, it actively aims to restore natural environmental processes. This might include creating green spaces that promote biodiversity, sustainable water management, and adopting architectural solutions that reflect and support natural cycles.

Social and Economic Implications

This approach doesn’t only concern the environment. It also holds a significant social and economic implications. Regenerative architecture can contribute to creating communities more connected with nature. Improving the quality of life and simultaneously promoting a sustainable economy through innovative and environmentally respectful solutions.

Regenerative design in architecture: beyond sustainability

Regenerative architecture proposes an approach to architecture and urban design that goes beyond sustainability and the concept of NZEB buildings: its goal is not only to reduce the environmental impact of buildings and the communities that inhabit them but also to regenerate and enhance the surrounding environment.

A key aspect of regenerative landscape architecture is regenerative design, an innovative design methodology aimed at reactivating and renewing an environment through the creation of synergies between social needs and respect for the natural environment. This approach evolves from the principles of sustainable development, incorporating aspects such as environmental responsibility, social justice, and economic efficiency.

The theoretical foundations of this practice focus on the community level, emphasizing the generation and recycling of energy and materials through natural processes. John T. Lyle has suggested twelve key strategies for implementing regenerative projects, including using nature as a model and context, aggregation rather than isolation, achieving optimal balance, harmonizing technology with needs, and sustainable resource management.

These principles have become the basis for developing a methodological framework that includes parameters for assessing energy performance, regulations (such as EPBD and EMAS), certification standards (such as LEED, LCA, ICMQ), and concepts of bioclimatic design.

The long-term goal is to provide design guidelines for the harmonious co-evolution of systems in urban energy retrofit interventions. This translates into improvements in technological feasibility, performance, sustainability, and quality, aiming to recover urban identity and promote social inclusion and accessibility.

A critical aspect of applying regenerative design is the challenge of economic feasibility and uncertainty regarding the future performance of buildings. Despite numerous examples at the urban scale, implementation at the individual building level remains complex, especially in terms of self-sufficiency.

This approach contributes to social improvement through participatory engagement of users, emphasizing the relationship between aspirations, needs, and design outcomes, and strengthening the sense of belonging and identity.

In summary, regenerative design requires a shift in perspective, moving the focus from objects to relationships to ensure the stability of ecosystems based on biodiversity and the complexity of their networks. In this context, buildings become catalysts for positive change, functioning as living systems integrated into their habitat and promoting beneficial interactions between the built environment, the living world, and human beings.

Limiting vs. Reintegrating

Sustainable design focuses on responsible resources, seeking to limit their use and minimize their environmental impact. On the other hand, regenerative design, as mentioned, goes beyond, aspiring to actively reintegrate resources into the built environment. This aspiration represents a fundamental paradigm shift: not just limiting damage but actively contributing to environmental regeneration.

Architecture as an Extension of Place

In regenerative design, architecture ceases to be just an isolated structure and becomes an extension of the place it occupies. This implies a profound interaction with the specific site, considering not only the functional aspect of buildings. But also their relationship with the topography, flora, fauna and surrounding ecosystem. This involves creating ecological corridors, preserving natural habitats, or promoting green spaces that act as biodiversity sanctuaries. Architecture thus becomes a landscape organic element.

Regenerative architecture and design

Systemic Thinking in Architecture

Contemporary architecture is increasingly embracing systemic thinking as a fundamental pillar in designing regenerative environments. This paradigm, known as systemic thinking, radically transforms the perception of buildings. Conceiving them not as isolated entities but as interconnected nodes in a vast network of social, environmental and business relationships. Let’s see how systemic thinking translates into architecture, emphasizing the need for a holistic and integrated vision.

By integrating microclimate and soil dynamics into design, architects aim to create buildings that not only adapt to the surrounding environment but also actively contribute to its balance. This concept of a building as part of a natural system represents a step forward from traditional design. Systemic thinking requires a deep understanding of how a building interacts with the local microclimate. The form, orientation and buildings’ materials must be carefully studied to optimize natural resources use, such as sunlight and ventilation. This synergistic interaction not only improves the building’s energy efficiency but also contributes by creating a healthy and sustainable microenvironment.

In addition to considering the direct environmental impact of a building, it takes into account social and possibly the business connections it generates. This integrated perspective helps create buildings that are not only harmoniously fit into their physical context but also into the broader social and economic context. In systemic thinking sense, the architect assumes a systems thinker role, considering multiple variables and relationships involved in building design. This evolution of the professional role requires multidisciplinary skills and closer collaboration with professionals from related fields, such as environmental engineers and landscape architects.

How to apply the circular approach in architecture: models and diagrams

The key concepts of regenerative architecture can be expressed through diagrams and models that show the interconnection relationships between buildings and the surrounding space.

The circular approach of regenerative architecture, based on the reuse of existing buildings and spaces, particularly those that are unused, modifying their functions and thus creating new economic and social opportunities, can be well expressed through a closed-loop system.

Circular model of regenerative architecture

According to such a system, it is advisable to:

• redesign the existing, renewing construction processes, adapting existing spaces to new needs, without neglecting human, social, and economic development, with an integrated approach;
• reduce the demolition of construction materials, because waste management represents a key aspect in terms of environmental impact;
• reuse, based on the principle of selective demolition, through a “systematic disassembly” of the building in order to recover its components with the aim of putting them back into circulation.

Case study of regenerative architecture: from design to construction

To create regenerative buildings, it is not only necessary to reduce energy loads to limit waste and produce renewable energy naturally, but it is essential to consider the dwelling as if it were a living organism, which reacts to changes in the surrounding environment and regenerates its own resources.

This translates into a process that involves all phases of a building, from its conception to its realization and is based on principles such as:

• the reuse of rainwater and greywater for irrigation;
• the self-production of the energy necessary for the operation of appliances and the air conditioning system, utilizing renewable sources (sun, wind, geothermal heat);
• biomimicry, recalling and respecting the forms of the surrounding environment;
• the use of natural, sustainable, and low-impact materials.

In the perspective of developing new materials inspired by the principles of nature itself, Neri Oxman and her research group, The Mediated Matter, instead of continuing to produce non-biodegradable synthetic materials, create organic compounds that can be reabsorbed by nature without leaving a negative impact on the environment.

An example is the Aguahoja project, two pavilions that collect structures and objects made from shrimp shells, insect exoskeletons, and dead leaves, 3D printed by a robot, shaped by water, and colored with natural pigments.

The result is a matter-organism made of biopolymeric compounds, which captures carbon dioxide, enhances pollination, increases soil microorganisms, and provides nutrients.

Examples of regenerative architecture projects around the world

Among the examples of regenerative architecture projects are:

• the Permaculture Garden created by artist Toni P. Ledesma, in Quezon City, Philippines. This garden promotes sustainable agricultural practices, integrating natural systems to grow food, manage water, and reduce environmental impact;
• the Smog Free Tower in Rotterdam, designed by Daan Roosegaarde, is the world’s first “anti-smog vacuum cleaner.” Standing 7 meters tall, it uses patented positive ionization technology to clean 30,000 m³ of air per hour, providing clean air in public spaces;
• the Rio Manzanares in Madrid, an urban regeneration project that extends along the Manzanares River in Madrid, which has seen the creation of parks and public spaces along the river, aimed at improving access to the watercourse and promoting socialization and outdoor activities. The project incorporated ecological solutions, such as water treatment and the creation of natural habitats, transforming a degraded area along the river into a vibrant and sustainable public space.

The role of regenerative materials in architectural innovation

The heart of regenerative design is undoubtedly regenerative materials, which not only do not harm the environment but also manage to repair and improve it.

These materials are capable not only of reducing environmental impact but also of leaving a positive and tangible mark on nature.

Bio-based materials can indeed improve indoor air quality, regulate temperature, and even reduce the need for mechanical heating or cooling, thus contributing to more efficient energy management of buildings.

Among these materials, we recall photocatalytic cement, which absorbs CO₂ from the atmosphere, demonstrating that architecture can truly combat climate change.

In recent years, numerous companies have also been experimenting with materials such as fungi and algae.

Bioplastics derived from algae or mycelium, which is the vegetative part of fungi, can offer renewable alternatives, as well as biodegradable options, to traditional materials.

For example, mycelium acts as a natural network. It is a network of filaments through which nutrients and chemicals travel, connected in a symbiotic system, and when combined with materials such as hemp, linen, jute, etc., they give rise to natural compounds that are a green alternative to synthetic materials.

The Need for Regenerative Architecture

The concept of regenerative architecture, emerging in response to environmental challenges, represents a design typology that operates as a closed-loop system. From this perspective, buildings become self-sufficient in eliminating waste, gathering or utilizing resources as well as self-powering. While nature serves as the archetype for regenerative design, modern technology offers opportunities for its full implementation.

Passive design, fundamental in regenerative architecture, finds examples in the past, such as ancient buildings in the American Southwest. These demonstrate the possibility of ensuring comfort without HVAC use, employing passive design techniques like maximum southern exposure and strategic window placement for natural ventilation.

For a deeper connection with the environment, regenerative architecture integrates native flora both inside and outside buildings. Indigenous plants, adapted to the local climate, offer advantages such as survival without additional water and the promotion of native species presence, contributing to ecosystem balance. The use of native plants, even on rooftops as in green roofs, reduces CO2 levels and mitigates the “heat island” effect in urban areas.

Regenerative architecture looks to new technologies to ensure self-sustainability. It shapes up as a cutting-edge approach in designing living spaces. Its implementation not only meets contemporary sustainability needs but also charts a path towards buildings that, much like nature itself, actively participate in the regenerative cycle of the environment.

The necessity for regenerative architecture emphasizes the importance of collective commitment. Architects, urban planners and society as a whole must collaborate to create built environments. One that not only meet current needs but also positively contribute to our planet’s health and future generations.

What tool to use for regenerative architecture

To effectively apply the principles of regenerative architecture, professionals need tools capable of providing reliable analyses and realistic forecasts on the energy performance of buildings.

In this sense, dynamic simulation represents a fundamental step: unlike steady-state calculations, which provide only a partial view of the building’s behavior, dynamic calculations allow for detailed assessments of consumption, comfort, and impacts throughout the entire life cycle.

A 3D BIM modeling software with advanced dynamic simulation functions allows for the integration of dedicated object libraries, customizable setpoints and usage profiles, updated climatic data, and comprehensive reports with tables, graphs, and 3D views. This way, it is possible to compare alternative design scenarios and support decisions based on objective data, transforming the principles of regenerative architecture into concrete, measurable, and shareable results with clients and stakeholders.

Here you can see the video of the presentation of the BIM energy software.

FAQ on regenerative architecture

What is the difference between sustainable architecture and regenerative architecture?
