Substantiating the Scope of Code: Eco-Niwas Samhita
Alliance for an Energy Efficient Economy

This report presents the findings of our study that analyses the residential building stock and the applicability criteria of ENS, as defined by Bureau of Energy Efficiency (BEE). The study carried out under the SHEETAL project is funded by CIFF. The report features the assessment of city jurisdiction area in ten million-plus cities across India covering the five climatic zones, conducted to gauge the housing trend dominating the urban landscape. The study highlights the predominant building typology of the identified sample plots, the area shares of each housing typology of the identified plots in the scope of ENS. The report also assesses the spans of ENS applicability based on the existing sampling of the residential building stock.

This report puts forth a suggestive mechanism in the document which may help ULBs, concerned city authorities to identify local factors and modify the scope of ENS accordingly and implement the code.

Model Government Zero Emissions Buildings Policy
New Buildings Institute

Released by New Buildings Institute, the Model Government Zero Emissions Buildings Policy provides plug-and-play policy language for jurisdictions considering taking a “lead by example” approach to building decarbonization. By using their own buildings to demonstrate how new technologies and operational procedures can both reduce energy and carbon emissions, governments can show the market what’s possible. They also demonstrate all the ways in which zero emissions buildings benefit owners, tenants and the general public—by lowering operating costs, reducing pollution and serving as comfortable, healthy places to work, live, learn and recreate.

Roadmap for Energy-Efficient Buildings and Construction in the Association of Southeast Asian Nations

The buildings sector plays a key role in decarbonising the global economy. In the Association of Southeast Asian Nations (ASEAN), buildings account for close to a quarter of the region’s total final energy consumption and energy-related CO2emissions. With continued economic development, urbanisation and population growth across the region, the International Energy Agency’s (IEA) analysis shows that both final energy consumption and CO2 emissions in buildings will continue to grow without ambitious policy actions. Improving the energy efficiency of building envelopes and systems, increasing renewable energy utilisation, phasing out the use of traditional biomass and switching to clean cooking and electricity, while enhancing energy access for vulnerable households across the region, can result in more than a 60% reduction in CO2 emissions from buildings by 2040 in relation to 2020, and provide many other benefits to households, society and governments. 


The Roadmap for Energy-Efficient Buildings and Construction in ASEAN focuses on the policy tools available for ASEAN Member States to drive energy efficiency improvements in the building sector to help meet growing needs for residential and non-residential floor space and energy services, while limiting the growth in energy demand and related emissions. It identifies key energy-efficient and low-carbon actions and activities that governments could consider for implementation by 2025, 2030 and beyond, moving towards net zero-carbon buildings.

Biomaterials Supporting the Transition to a Circular Built Environment in the Global South
Yale Center for Ecosystems in Architecture

Building construction materials represent 11% of global carbon emissions and 28% of the annual buildings related CO2 emissions, and yet, the demand for construction materials continues to grow, especially in the rapidly urbanizing Global South. Biomaterials offer a key opportunity for decarbonizing the buildings and construction sector, through transitioning from current linear, extractive, and toxic construction practices towards circular, bio-based, renewable materials and construction methods for a sustainable future. While this transition has the potential to drastically reduce both the need for natural resources and the carbon footprint of urban growth, policy intervention is required to enable the sustainable development of biomaterials, contributing to 10 of the 17 SDGs.

Yale Center for Ecosystems in Architecture (Yale CEA) and UNEP are launching a new report entitled “Biomaterials Supporting the Transition to a Circular Built Environment in the Global South”. The report explores the transformational socio-economic and environmental impacts that an accelerated transition to a bio-based, circular material economy could have, particularly for the Global South.

Decarbonising Buildings in Cities and Regions

Accounting for nearly 40% of global CO2 emissions and sometimes as much as 70% in large cities, buildings and construction are central to the low-carbon transition. Decarbonising buildings, especially the old stock, through energy efficiency improvements and renewable energy use, not only reduces carbon emissions, but also generates co-benefits in health, energy affordability and the labour market. Additionally, global mega-trends and the transition to a green recovery from COVID-19 provide impetus for stakeholders to take action. Cities and regions have a key role to play and can leverage prerogatives in regulation, public procurement and stakeholder engagement, while addressing multiple governance, capacity and funding gaps. To accelerate and scale up their action, cities and regions need to work with national governments to create an effective governance mechanism. Drawing on the findings of a dedicated survey of cities and regions of all sizes from both OECD and non-OECD countries, this report explains their significant role, explores sub-national policy measures, identifies key obstacles, and provides policy recommendations and a checklist for both national and subnational governments to drive the decarbonisation of buildings in cities and regions.

Compendium on GHG Emissions Baselines & Monitoring: Buildings sector Versions
UNFCCC secretariat

This volume on the building and construction sector provides an overview of the different sources of GHG emissions from the building and construction sector, as well as methodologies for quantifying these emissions to feed into the preparation and reporting of national GHG inventories. By better understanding the sources of emissions over the whole life cycle of buildings, it thus provides guidance on the most appropriate and effective mitigation strategies and policies for decarbonizing the building and construction sector based on national circumstances. We are optimistic that the guidance contained in this volume will be of some help to developing country Parties to make informed choices when setting building and construction sector emission reduction targets; implementing climate change mitigation actions and reporting on them in their national communications,biennial update reports and in future, biennial transparency reports.

Implementing the Paris Agreement and reducing greenhouse gas emissions throughout the life cycle of buildings: European public policies, tools and market initiatives

The built environment offers significant carbon mitigation potential: decisive policy action will not only address the ongoing climate emergency we are facing, but will also directly reduce energy costs and improve security of supply, and has the potential to create widespread business opportunities and significant numbers of new, local jobs. Based on this context, the study presented in this report was developed at the request of the Brazilian Ministry of Mines and Energy (MME) within the framework of the Specific Partnerships for Implementation of the Paris Agreement (SPIPA). This report discusses policies, tools and market initiatives aimed at reducing upfront emissions – that is, the embodied carbon associated with building construction, including the extraction and processing of materials.

EPBD Recast: New provisions need sharpening to hit climate targets

This policy briefing finds that the European Commission’s December 15th EPBD recast proposal does not yet reflect the crucial role the EPBD should play within the Fit for 55 Package and within the greater narrative of securing energy independence. While it is welcome that many provisions are either introduced or open for modification, they will not deliver on the Directive’s objectives if the ambition is not set at the right level, and if measures are not made more stringent and coherent.  Ultimately, the scope of the EPBD recast proposal is incomplete, as the updated 2050 vision for the building stock only considers the operational phase of emissions from buildings. The long-term vision is also unbalanced, with a focus on reducing operational greenhouse gas emissions mainly through a full switch to renewables, while the “energy efficiency first” principle is not reflected in the outlined provisions. With the legislative process starting, there is now an opportunity to ensure the final Directive is improved and fully aligned with the EU 2030 and 2050 climate and energy efficiency objectives.

Roadmap to climate-proof buildings and construction – How to embed whole-life carbon in the EPBD

Background: Climate change action is time critical. There is an immediate need to focus policy and market actions on emission reductions across the entire life cycle of buildings as these are very quickly using up the remaining carbon budget left before the tipping point of an irreversible climate crisis. This provides a compelling reason for policymakers to address all sources of carbon emissions from the buildings and construction sector, including both embodied and operational carbon – together referred to as “whole-life” carbon (WLC) emissions. Reducing embodied emissions is a global challenge that offers significant carbon reduction potential. Some countries in Europe (one of the leading regions addressing this challenge) have introduced policies to reduce whole-life carbon emissions from buildings and construction, with further national and EU-level initiatives expected in the near future. The ongoing review of key policy and legislative files provides a significant opportunity for the EU to begin consistently integrating WLC in the policy framework. About this roadmap: This roadmap for integrating WLC in the policy framework primarily focuses on the pending review of the Energy Performance of Buildings Directive (EPBD) but also makes links to the Energy Efficiency Directive (EED) and the Construction Products Regulation (CPR). The cornerstones of how to fully decarbonise the European Union’s building stock along its entire lifecycle must be laid now. Member States but also private actors need guidance and security to direct investments and set the framework to steer the required actions and trigger innovation. Considering the next revision is only planned by end of 2027, the time to get this right is now. BPIE's new roadmap sets out the necessary steps to introduce WLC considerations and align the provisions of the EPBD with climate-neutrality goals.
