This report applies network analysis to examine the interdependencies between 75 policy and finance instruments, as well as 22 barriers, to support the transition to net zero carbon buildings. Such a network analysis approach allows us to move beyond case studies to explore potential high-impact pathways for cities to support a low-carbon transition for the building sector effectively.

Developing a systemic representation of the building sector allows us to answer the following questions:

  • Which barriers should we prioritize to ensure systemic transformation of the building sector?
  • Which instruments should we roll out, and in what sequence?
  • What pathways can cities follow to transition to a fully decarbonized building sector?

This report offers initial findings on the general challenges and mechanisms behind the transition towards a net zero carbon buildings sector, helping shed light on concrete pathways cities can implement to decarbonize the building sector.

Zero Carbon Building Accelerator Project

The Türkiye Building Sector Decarbonization Roadmap was meticulously developed through a transparent, participatory process within the framework of the Zero Carbon Building Accelerator (ZCBA) project, which was implemented in Colombia and Türkiye between 2021-2023. The roadmap aims to guide the building and construction industry by offering comprehensive, pioneering, and sustainable solutions to achieve the goal of combating climate change. The roadmap has been structured to reflect Türkiye’s carbon emission reduction targets and has the goal of reducing emissions throughout the entire lifecycle of buildings. It aims to transform the building industry by increasing energy efficiency, transitioning to renewable energy sources, and promoting environmentally friendly building materials and construction methods. Additionally, it includes strategies to increase the climate resilience of the building sector.

The Extended Summary provides an overview of significant information in the Roadmap.

Passive House Accelerator

The fall 2023 issue of Passive House Accelerator explores how the benefits of Passive House construction can turn buildings into islands of tranquility.

Case studies in this issue include an affordable apartment building in the Bronx, a warehouse in the Hudson Valley, a prefabricated classroom on a Spanish beach, and the world's first Passive House certified hospital in Germany.

This issue examines how the benefits of Passive House construction—particularly improved indoor air quality and protection from external noise pollution—can positively affect occupant health in addition to decarbonizing the built environment. This issue also highlights how the principles of Passive House design and construction can be applied to any building typology and in any climate.

How does the large-scale application of biobased construction materials impact our forests? Are we not shifting the burden to another planetary boundary if we focus on the reduction of carbon emissions?

This report from Metabolic is a first step in a longer-term exploration to create clarity on these important issues.

This report delves into the current environmental impact of the construction sector in the EU27+UK; the potential scenarios to reduce the impact of the sector by applying timber alternatives to carbon-intensive materials; the implications that this increased demand for timber has on European forests, and what systemic barriers need to be taken into consideration during the planning and development processes.

This report is part of a three-part series led by CCFLA to promote an understanding of financing barriers to net zero carbon buildingsThis paper particularly focuses on Nigeria and assesses the current use of financial and policy instruments, and identifies how national, state, and local policy and regulatory frameworks can be improved to drive private and public investment in this sector. This report evaluates the current use of financial and policy instruments to identify ways to strengthen national, state, and municipal policy and regulatory frameworks to encourage private and public investment in this area.

The policy environment in Nigeria for net zero-carbon buildings is fragmented. While there is no overarching strategy or policy on net zero-carbon buildings, several relevant elements can be found in a variety of legislation.

While the 2017 National Building Energy Efficiency Code (BEEC) establishes minimum efficiency requirements for new structures, the 2021 National Climate Change Policy gives policy guidelines on building energy efficiency retrofitting.

ELA published today a report concerning information provision, enforcement, social security coordination and cooperation between Member States in relation to posting of workers in the construction sector. The study, which findings are presented in the report, was conducted between October 2022 and May 2023.

The study shows that the most prevalent violations and abusive practices include the establishment of letterbox companies, non-compliance with working conditions, bogus self-employment, fraudulent PD A1 (Portable Document A1) usage and fraudulent posting of third country nationals. Labour inspectorates can inspect and sanction these violations and abusive practices, but they often lack sufficient financial and staff resources, and experience difficulties in identifying some factual elements in such posting contexts (e.g. place of registration of undertakings, number of contracts performed, whether or not the posted workers return to or are expected to resume working in the sending Member State) to properly carry out their inspection activities. Furthermore, imposition of sanctions and their effective implementation can be difficult in a cross-border situation.

The report identified several measures that could prevent non-compliance with the rules. These include the provision of social ID cards to posted workers, subcontracting chain liability schemes to make it possible to identify the actors in those chains, limitations on subcontracting and specific public procurement rules.

Bauhaus Earth is collaborating with the Toni Piëch Foundation to develop the multi-series knowledge collection 'Building for the Future'. Developed as a modular system, the collection will provide visually appealing and easily digestible information to introduce people to the idea of a regenerative built environment. It will provide an overview of key developments, concepts, and options for action. The first series, 'Setting the Frame', highlights critical facts and figures about the built environment as a major contributor to the climate crisis. It also highlights the vision of a regenerative built environment and presents practical ideas and approaches. The second series will focus specifically on the scale of regenerative buildings, highlighting the use of bio-based materials and how to extend the life cycle of building materials and components, as well as the importance of sufficiency strategies.

The Cooling Web is a guidance document and a compilation of case studies that bring out a range of cooling solutions that are diverse and comprehensive and do not rely on conventional energy-guzzling practices. This involves measures to enhance microclimate, thoughtful designs for building envelopes, judicious selection of material, and context-specific cooling approaches.

India is witnessing rising frequency and intensity of heat waves. This is making our cities sear and pushing the built environment community to rethink how to plan and design buildings and cities. This momentum is strongly linked with the India Cooling Action Plan 2019 and its very important goal of thermal comfort for all. The Union government and a few state governments are taking strides to achieve this goal by developing thermal comfort standards and action plans, adopting energy conservation building codes, and other initiatives like cool roof programmes. However, the degree of success lies in the scaled-up implementation of cooling strategies.

The 10 case studies in the volume 1 carefully selected from across the country—with five deep dives—highlight how thermal comfort can be achieved by a combination of passive and active cooling measures. This approach reduces cooling energy demand tremendously and addresses cooling equity. These solutions blend traditional wisdom on passive design with modern techniques and provide optimized solutions so that energy consumption is minimized. These solutions are also a guide toward achieving a rational and climate-appropriate cooling ecosystem that not only ensures resource efficiency but also maintains thermal comfort for building occupants.

The Digital Construction Material Passport (DCMP) is a groundbreaking tool designed to enhance transparency and sustainability in the construction industry. Much like food products require detailed ingredient information, construction materials also deserve comprehensive data to support informed decision-making.

A material passport serves as a declaration of a construction product's essential information, such as its composition, production chemistry, and potential for sustainable construction. This passport is supplied by the manufacturer and accompanies the product through the supply chain. Material passports contain data on chemical content, resource potential, and the product's operational and environmental impact. While some environmental indicators are found in Environmental Product Declarations (EPDs), material passports cover other vital information for construction processes.

Material passports and building passports are related but distinct concepts. Material passports provide product-specific data, while building passports include project-specific information like renovations. Material passports are a prerequisite for building passports.

The DCMP is an open-source free communication format for safely communicating detailed information about construction products, i.e. an electronic material passport specifically for construction products. It can contain information about ingredients, chemistry used in production and the products ability to be part of circular/sustainable construction as well as future resource flows. The data format is based on XML and is free to implement by anyone. To encourage its usage there is also a free editor available to create, read, and update files in this format.
