The Sufficiency Action Hub aims to demonstrate the necessity, feasibility, and social desirability of sufficiency measures in the building sector, fostering a shared understanding across decision-making levels. Its goal is to build a diverse community of stakeholders worldwide, from various sectors of the building value chain, to adapt sufficiency solutions to different contexts, recognizing disparities between the Global North and South. Launched by the French Institute for Building Performance and supported by key institutions like ADEME, the initiative seeks to address the environmental challenges posed by the building sector, which is responsible for 21% of global greenhouse gas emissions. The Action Hub highlights the urgent need for sufficiency measures, advocating for a systemic approach that integrates demand-side policies to reduce resource consumption, mitigate emissions, and ensure social equity. Through international collaboration and the adoption of the "Sufficiency First" principle, the initiative aims to reshape the future of the building sector within planetary boundaries. The Action Hub has recently published a report outlining the key findings of its ongoing work and initiatives.  

Since its launch at COP 26, the Breakthrough Agenda has become established as an annual collaborative process centred around the Conference of the Parties (COP) meetings of the United Nations Framework Convention on Climate Change (UNFCCC). It is currently supported by 59 countries representing over 80% of global GDP, and by over 100 initiatives working to enhance collaboration within major emitting sectors. Countries can endorse Breakthrough goals to make clean technologies and sustainable practices more affordable, accessible and attractive than their alternatives by 2030 in the power, road transport, hydrogen, steel, cement, buildings and agriculture sectors. This report covers six of the seven sectors, with agricultural covered in a separate report.

The Breakthrough Agenda establishes an annual cycle to track developments towards these goals, identify where further coordinated international action is urgently needed to accelerate progress and then galvanise public and private international action behind these specific priorities in order to make these transitions quicker, cheaper, and easier for all.

To initiate this cycle, world leaders tasked the IEA and the UN Climate Change High Level Champions to develop an annual Breakthrough Agenda report to provide an independent evidence base and expert recommendations for where stronger international collaboration is needed.

This document, the 2024 Breakthrough Agenda Report, is the third of these annual reports. It provides an assessment of progress against the recommendations made last year, updating recommendations for what more needs to be done.

This year's report includes the second edition of the Buildings Chapter, developed in collaboration with the GlobalABC. The chapter highlights progress in the built environment and calls on governments to strengthen collaboration, in five priority areas: standards & certification, demand creation,  finance & investment, research & deployment, capacity & skills– to accelerate decarbonisation and enhance resilience in buildings.

The 2024 Energy Performance of Buildings Directive (EPBD) recast introduces more stringent provisions for EPCs and establishes a framework for renovation passports as an additional voluntary tool to provide a clear roadmap for staged deep renovations. In accordance with Article 12 of the EPBD, Member States are required to put in place a renovation passport scheme by 29 May 2026 based on the common framework set out in Annex VIII of the EPBD.

The iBRoad2EPC project has developed a flexible, adaptable and modular model renovation passport that provides a set of solutions that can be immediately applied to the transposition and/or implementation of a number of EU policy instruments.

The present report includes a detailed analysis of how iBRoad2EPC can support and facilitate the implementation of each article of the EPBD and its requirements for the renovation passports as set in Annex VIII, as well as the Renovation Wave strategy, the Energy Efficiency Directive (EED) and the Renewable Energy Directive (RED). The analysis then informs concrete actions to maximise the uptake of iBRoad2EPC to achieve the EU’s decarbonisation goals.

The iBRoad2EPC EU roadmap thus provides guidance to policymakers on how to optimally prepare the ground for national roll out and maximise the use of iBRoad2EPC to accelerate deep renovation in the EU. It thereby provides recommendations for improving the implementation of related Directives or amending the regulatory framework to promote deep renovation, and how to best use iBRoad2EPC for this purpose.

Decarbonizing existing buildings is challenging but necessary to achieve climate goals. To accelerate progress, we need to make energy retrofits more accessible, affordable, and commonplace. A viable market for decarbonization and a streamlined retrofitting process can help make these efforts more equitable and cost-effective today.

The majority of US buildings that will exist in 2050 are already standing. Reducing climate pollution from leaky and inefficient existing buildings that run on fossil fuels is fundamental to any climate strategy. Yet the typical retrofitting process depends heavily on owners and is fraught with uncertainty. Conflicting guidance, high costs, fragmented financing, and administrative burdens are all significant hurdles that owners and service providers face impeding the widespread adoption of retrofitting solutions. There is an urgency to develop a robust market for building decarbonization to meet climate targets. Efforts to induce and support this shift should be focused on scalable solutions, favorable policies, and programmatic systems.

In recent years, RMI has focused on accelerating deep energy retrofits for affordable housing across Massachusetts to catalyze the growth of a viable regional market for building decarbonization by facilitating key “lighthouse projects.” These projects serve as exemplary models for eliminating on-site fossil fuels, maximizing efficiencies, reducing emissions, and enhancing comfort and health for low- and middle-income residents. This report outlines our progress in Massachusetts to date, synthesizing observations of the current market, including enabling factors for decarbonization such as extensive stakeholder engagement and knowledge-sharing platforms. We identify common challenges including difficulties with decarbonization assessments, financial barriers, and administrative burdens.

As a result of these direct project engagements, the report also distills lessons learned into suggested paradigm shifts to scale building decarbonization, such as adopting holistic building design approaches and integrating standardized frameworks. RMI proposes foundational and strategic actions to reinforce a landscape conducive to building retrofits that benefit low-income households and preserve a livable climate for future generations. By developing, refining, and sharing best practices, processes, and strategies across the industry, stakeholders can stimulate a thriving market for building decarbonization and drive progress toward a low-carbon future.

The new Finnish Construction Act includes obligations concerning sustainable construction that stress carbon reduction and longevity of buildings. The latter contains a new essential technical requirement concerning the lifecycle performance of a building. The lifecycle performance comprises durability, adaptability and reusability. Thus they also have impacts on the use value and economic value of buildings.

The basic condition for the management of lifecycle performance is that in construction projects precise and verifiable requirements can be set for lifecycle performance. This in turn requires that the lifecycle performance and indicators for them have been defined. The Ministry of the Environment started an expert process in 2022 that aims to further specify the concepts related to lifecycle performance and present a summary and development proposals for the evaluation, planning and guidelines concerning lifecycle performance.

This report presents some of the content produced in the expert process and proposes that, after having been further specified, lifecycle performance should be more systematically incorporated into the procurements and guidance of construction. The report lays the foundation for a systematic approach to lifecycle planning and gives recommendations for further development opportunities related to the topic.

Since 2015, the Healthy Homes Barometer has been tracking the state of European Union (EU) homes and shining a light on workplaces and educational institutions. The 2024 edition has been renamed as the Healthy Buildings Barometer (HBB) to reflect the fact it now extends to all major building types, giving us significant insights into all our buildings and their users’ health. The 2024 edition also includes a comprehensive framework for healthy buildings based on scientific research and illustrated through 12 case studies from across the EU. Policymakers at national and EU levels, as well as building sector stakeholders, can use this Healthy Buildings Barometer and its framework as a guide to achieving healthy and sustainable buildings across Europe.

This report discusses ways of enhancing government capacities to prevent, react and rebuild, thereby minimising the impact of natural disasters on infrastructure assets and operations. It identifies data, collaboration and technologies as drivers of resilience, and highlights financial resources, technical skills and regulatory frameworks as key enablers. The report presents seven actionable principles to ensure infrastructure resilience, drawing from global good practices and in-depth analysis of infrastructure projects in Colombia, Ghana, India, Indonesia, Japan, Mozambique and the United States.

The Global Status Report for Buildings and Construction (Buildings-GSR), a report published by the UN Environment Programme (UNEP) and the Global Alliance for Buildings and Construction (GlobalABC), provides an annual snapshot of the progress of the buildings and construction sector on a global scale. The Buildings-GSR reviews the status of policies, finance, technologies, and solutions to monitor whether the sector is aligned with the Paris Agreement goals. It also provides stakeholders with evidence to persuade policymakers and the overall buildings and construction community to take action.

As outlined in the latest edition, the buildings and construction sector contributes significantly to global climate change, accounting for about 21 per cent of global greenhouse gas emissions. In 2022, buildings were responsible for 34 per cent global energy demand and 37 per cent of energy and process-related carbon dioxide (CO2) emissions.

Policy progress is evident with more comprehensive climate action plans covering buildings and construction in Nationally Determined Contributions (NDCs). However, few align with net-zero operational emissions, and while over 81 countries have building energy codes, many are outdated.Investment in building decarbonisation exceeded US$285 billion in 2022 but is expected to decline in 2023, largely due to a less favourable investment environment due to rising costs. The necessary increase in investments falls short of the net-zero targets for new and existing buildings by 2030 and 2050, respectively.

The 2022 update of the Global Buildings Climate Tracker (GBCT) paints a concerning picture: the gap between the current state and the desired decarbonisation path is significant. To align with the 2030 milestone, an annual increase of ten decarbonisation points is now required, a substantial jump from the six points anticipated per year starting in 2015.

The GBCT shows a negative rebound since 2020 in the decarbonization of the buildings sector, with increased energy intensity and higher emissions. The gap between the actual climate performance of the sector and the necessary decarbonization pathway is widening. The lack of structural or systemic decarbonisation improvement in the building sector leaves its emissions reductions vulnerable to external factors.

To reach the goals of net-zero carbon emission buildings for new buildings by 2030 and existing buildings by 2050, stronger policies are needed to enhance energy efficiency and address carbon emissions from building materials and construction. National efforts are crucial, with countries forming coalitions to share best practices and promote low-carbon construction.

This year, the deep dive chapters are the following: Adaptation and resilient construction methods; Innovations in business cases (renovation and green building construction industry); and Nature-based solutions and biophilic design.

A welcome development in 2023 was the Buildings Breakthrough launched at COP28, to coordinate between countries to make clean technologies and sustainable solutions in the buildings and construction sector the most affordable, accessible, and attractive option in all regions by 2030.

Looking forward to 2024, the focus must be on tangible emission reductions, enhancing building performance, increasing renewable energy use and addressing housing and energy access disparities. Despite the complexities, strategic partnerships can facilitate the shift to an efficient, resilient and whole life net-zero carbon global building stock.

The report highlights the urgent global crisis of climate change, emphasizing its wide-ranging consequences on the environment, biodiversity, human health, and poverty. It particularly focuses on the vulnerability of the built environment to climate change impacts and stresses the need for immediate adaptation measures. Despite the clear benefits and urgent need for adaptation, there's a notable delay in embracing and implementing adaptation strategies across stakeholders within the buildings and construction sector, though the report demonstrates that each stakeholder already has tools and levers to contribute to the resilience of the built environment. The text then addresses various challenges hindering adaptation efforts, including reluctance to bear initial costs, a predominant focus on mitigation rather than adaptation, and the need for local-level initiatives and financial resources. It calls for collective action, emphasizing the shared responsibility of all stakeholders in addressing climate change adaptation and ensuring a sustainable future.

The Building Energy Codes Working Group has released their latest report on Resilience Issues in Building Energy Codes, led by the Australian Government.

The report, authored by Adam Hinge, MD of Sustainable Energy Partnerships and prepared for the International Energy Agency’s (IEA) Building Energy Codes Working Group (BECWG), which is part of the IEA Energy in Buildings and Communities Technical Collaboration Programme (IEA EBC), focuses on the application of building energy codes to improve the building stock’s ability to provide safe indoor thermal conditions and function during extreme events. It reviews the relationship of building energy codes to other building resilience policies and strategies, such as other building/life safety codes, community planning, zoning or other land use regulation to discourage rebuilding in areas most prone to climate disasters, and other resilience planning strategies. The report provides an overview of how different jurisdictions address resilience issues through building energy codes in countries that are part of the IEA EBC Building Energy Codes Working Group.
