1. Introduction: The Imperative for Radical Innovation

The built environment is a significant contributor to global greenhouse gas emissions, resource consumption, and waste generation. According to the UN Environment Programme, buildings account for approximately 40% of global energy consumption and 36% of CO2 emissions [1]. Conventional approaches to sustainable building, while valuable, often result in incremental improvements that fall short of addressing the scale and urgency of the challenges. Radical innovation, characterized by its potential for disruptive change and significant impact, is essential to achieving deep decarbonization, resource efficiency, and enhanced resilience in the built environment.

Radical innovation can be defined as the introduction of products, processes, or business models that depart significantly from existing practices and have the potential to create new markets or transform existing ones [2]. In the context of the built environment, this could involve developing novel materials with significantly lower embodied carbon, adopting circular economy principles to minimize waste, or implementing smart building technologies that optimize energy performance in real-time. It also encompasses fundamental shifts in the way buildings are designed, constructed, financed, and operated, challenging traditional paradigms and fostering new collaborative models.

This report adopts a broad perspective on innovation, encompassing technological advancements, process improvements, and systemic changes. We argue that a holistic approach is necessary to unlock the full potential of innovation and create a truly sustainable built environment. The subsequent sections will delve into specific examples of radical innovations, analyze the barriers to adoption, and propose strategies to promote a more innovative and sustainable future for the built environment.

2. Disruptive Technologies: Materials Science and Beyond

Technological innovation is a crucial driver of progress in the built environment. Emerging technologies hold immense potential for revolutionizing building design, construction, and operation, leading to significant reductions in environmental impact and improvements in performance. Several key areas of technological innovation are highlighted below.

2.1. Advanced Building Materials

The embodied carbon of building materials represents a significant portion of the overall lifecycle carbon footprint of a building. Developing and adopting low-carbon and bio-based materials is therefore critical for achieving decarbonization goals. Examples of radical innovations in building materials include:

• Mass Timber Construction: Engineered wood products like cross-laminated timber (CLT) offer a sustainable alternative to concrete and steel in certain building applications. CLT is a renewable material that sequesters carbon dioxide from the atmosphere and has a lower embodied carbon footprint than traditional materials [3]. While there are concerns about sustainable forestry practices, managed forests are crucial for carbon sequestration. However, it is essential that CLT is sourced from sustainably managed forests.
• Bio-Based Materials: Materials derived from renewable biological sources, such as hempcrete, mycelium composites, and bamboo, offer a promising pathway to reducing embodied carbon and promoting circularity. Hempcrete, a mixture of hemp shives, lime, and water, is a carbon-negative building material with excellent insulation properties [4]. Mycelium composites, grown from fungal networks, can be used to create lightweight and biodegradable building components. The challenge with bio-based materials is in scaling up production to meet demand and ensuring durability and performance.
• Recycled and Upcycled Materials: Utilizing recycled and upcycled materials reduces waste and minimizes the environmental impact of resource extraction. Examples include using recycled plastics in concrete, repurposing shipping containers for building structures, and incorporating recycled aggregates in pavements. The widespread adoption of recycled and upcycled materials requires addressing concerns about quality, consistency, and regulatory barriers. Furthermore, ‘downcycling’ should be avoided wherever possible.
• Carbon Capture and Utilization (CCU) in Construction: Technologies that capture CO2 from industrial sources and utilize it in the production of building materials, such as concrete, offer a potential pathway to reducing the carbon footprint of construction. While still in its early stages of development, CCU has the potential to transform the concrete industry and other carbon-intensive sectors [5]. The scalability and long-term stability of carbon storage are crucial considerations for the widespread adoption of CCU technologies.

2.2. Smart Building Technologies

Smart building technologies leverage data analytics, automation, and connectivity to optimize building performance, enhance occupant comfort, and reduce energy consumption. Key innovations in this area include:

• Advanced Building Automation Systems (BAS): BAS integrate and control various building systems, such as HVAC, lighting, and security, to optimize energy performance and occupant comfort. Advanced BAS utilize machine learning algorithms to predict energy demand, adapt to changing conditions, and identify opportunities for energy savings [6].
• Internet of Things (IoT) Devices: IoT devices, such as sensors, actuators, and smart meters, collect data on building conditions and occupant behavior, providing valuable insights for optimizing building performance. IoT data can be used to personalize lighting and temperature settings, detect occupancy patterns, and identify maintenance needs.
• Digital Twins: A digital twin is a virtual representation of a physical building, capturing its design, construction, and operational data. Digital twins can be used to simulate building performance, identify potential problems, and optimize energy efficiency [7]. They can also facilitate predictive maintenance and improve building resilience.
• Artificial Intelligence (AI) in Building Management: AI can be used to automate building operations, predict energy consumption, and optimize building performance in real-time. AI-powered building management systems can learn from historical data, adapt to changing conditions, and identify opportunities for energy savings [8].

2.3. Additive Manufacturing (3D Printing)

Additive manufacturing, or 3D printing, offers a revolutionary approach to construction, enabling the creation of complex geometries, customized designs, and on-site production. 3D printing can reduce waste, minimize material transportation, and accelerate construction timelines [9]. While the technology is still in its early stages of adoption, it has the potential to transform the construction industry and enable the creation of more sustainable and resilient buildings.

3. Systemic Shifts: Circular Economy and Integrated Design

Beyond technological innovations, systemic shifts in the way buildings are designed, constructed, and operated are essential for achieving a truly sustainable built environment. Two key areas of systemic change are circular economy principles and integrated design processes.

3.1. Circular Economy in the Built Environment

The linear ‘take-make-dispose’ model of resource consumption is unsustainable in the long term. A circular economy aims to minimize waste and maximize resource utilization by closing the loop on material flows. In the built environment, this involves designing buildings for deconstruction and reuse, using recycled and upcycled materials, and implementing strategies to minimize waste during construction and demolition [10].

Key principles of a circular economy in the built environment include:

• Design for Disassembly (DfD): Designing buildings for easy disassembly and reuse of components at the end of their lifespan. This involves using modular construction techniques, reversible connections, and standardized components.
• Material Passporting: Creating a detailed inventory of the materials used in a building, including their composition, origin, and potential for reuse or recycling. Material passports facilitate the identification and recovery of valuable materials at the end of a building’s life.
• Waste Minimization: Implementing strategies to minimize waste during construction and demolition, such as using prefabrication techniques, optimizing material procurement, and segregating waste streams for recycling.
• Building as a Material Bank: Viewing buildings as temporary repositories of valuable materials that can be recovered and reused at the end of their lifespan. This requires a shift in mindset from demolition to deconstruction and a focus on material recovery and reuse.

3.2. Integrated Design Processes

Traditional building design processes often involve a fragmented approach, with architects, engineers, and contractors working in silos. Integrated design processes promote collaboration and communication among all stakeholders from the earliest stages of a project. This allows for a more holistic approach to building design, considering environmental, social, and economic factors. Integrated design processes can lead to more innovative and sustainable solutions [11].

Key elements of integrated design processes include:

• Early Collaboration: Engaging all stakeholders, including architects, engineers, contractors, and building owners, from the initial stages of a project.
• Shared Goals and Values: Establishing clear goals and values for the project, including sustainability targets and performance metrics.
• Iterative Design: Using an iterative design process, where ideas are tested and refined through feedback from all stakeholders.
• Life Cycle Assessment (LCA): Conducting a life cycle assessment to evaluate the environmental impacts of different design options and material choices.
• Building Information Modeling (BIM): Utilizing BIM to create a virtual model of the building, facilitating collaboration and communication among stakeholders.

4. Novel Approaches: Financing and Governance

Beyond technology and design, innovative approaches to financing and governance are essential for driving the adoption of sustainable building practices. This section explores two key areas: alternative financing models and innovative governance structures.

4.1. Alternative Financing Models

Traditional financing models often prioritize short-term profits over long-term sustainability. Alternative financing models can help to overcome this barrier by providing incentives for sustainable building practices. Examples of alternative financing models include:

• Green Bonds: Bonds issued to finance environmentally friendly projects, such as green buildings and renewable energy infrastructure. Green bonds provide investors with an opportunity to support sustainable development while earning a financial return [12].
• Energy Performance Contracting (EPC): A financing mechanism where a company guarantees energy savings for a building owner and receives a portion of the savings as payment. EPCs can help building owners to implement energy efficiency measures without upfront capital investment [13].
• Property Assessed Clean Energy (PACE) Financing: A financing mechanism that allows property owners to borrow money for energy efficiency improvements and repay the loan through their property taxes. PACE financing can make energy efficiency improvements more affordable for property owners.
• Crowdfunding: Raising capital from a large number of individuals through online platforms. Crowdfunding can be used to finance small-scale sustainable building projects and engage the community in the development process.

4.2. Innovative Governance Structures

Traditional governance structures can be slow to adapt to changing conditions and may not be well-suited to promoting sustainable building practices. Innovative governance structures can help to overcome these barriers by fostering collaboration, transparency, and accountability. Examples of innovative governance structures include:

• Public-Private Partnerships (PPPs): Collaborations between public and private sector entities to finance, design, construct, and operate infrastructure projects. PPPs can leverage private sector expertise and capital to deliver sustainable building projects more efficiently [14].
• Community Land Trusts (CLTs): Non-profit organizations that acquire land and hold it in trust for the benefit of the community. CLTs can be used to develop affordable and sustainable housing and promote community-led development.
• Cooperative Housing: Housing owned and managed by its residents. Cooperative housing can promote community engagement, affordability, and sustainability.
• Building Information Modeling (BIM) Mandates: Government policies that require the use of BIM on public sector building projects. BIM mandates can promote collaboration, transparency, and efficiency in the construction process.
