This issue of Danfoss's white papers presents a roadmap for decarbonizing cities. Cities account for two-thirds of global energy consumption and more than 70% of annual global carbon emissions. With more than half of the world’s population living in cities today – a number expected to increase to almost 70% in 2050 – we will not reach the goals of the Paris Agreement without a deep decarbonization of cities.

About 90% of homes in the Netherlands depending on natural gas for heating, the Netherlands has made a commitment to phase out natural gas by 2050. To achieve the goal, the Netherlands has rolled out a natural gas-free pilot programme in 66 neighbourhoods. These neighbourhood pilot projects enabled municipalities to learn what it takes to start energy transition.

Based on a city survey carried out across 26 local governments, key findings from this report call on national and local governments joining up their efforts to take place-based measures.

This paper is the first case study applying the policy framework presented in the OECD report Decarbonising Buildings in Cities and Regions published in March 2022. The present case study provides a deep dive into the Netherlands’ experience to demonstrate the potential of cities and regions to advance the decarbonisation of buildings.

This briefing by the European Environment Agency explores the nexus between climate change adaptation and mitigation, and the health and social justice aspects of cooling Europe’s buildings. It focuses specifically on residential buildings. The briefing is based on a literature review by Ramboll commissioned by the EEA, discussions held with members of the European Environment Information and Observation Network (Eionet), input from individual experts and information from other EEA publications.

The CARE (Carbon Avoided: Retrofit Estimator) Tool is used for estimating and comparing the embodied, operating, and avoided carbon impacts and benefits of reusing and upgrading existing buildings or replacing them with new construction. The CARE Tool allows users to compare the total carbon impacts of renovating an existing building vs. replacing it with a new one.

The CARE Tool is an Architecture 2030 Project. 

This report - Sri Lanka Roadmap for Sustainable Housing and Construction 2020 – 2050 - presents the findings of the Sustainable Building Construction Country Assessment for Sri Lanka (SBC-CA) and a Roadmap for Sustainable Housing and Construction and achieving NDCs in the construction industry in Sri Lanka. It examines the current status, and potential opportunities and challenges for adopting Sustainable Building Construction (SBC) practices and policies. The Country Assessment and the Roadmap are structured on the approach laid out by the ‘Global Alliance for Building Construction (GlobalABC) Roadmap for Buildings and Construction 2020-2050, where 8 Action Areas have been identified for the transition towards sustainability in the Construction Sector: Urban planning, New Buildings, Existing Buildings, Building Operations, Appliances and Systems, Materials, Resilience, and Clean Energy.

The Global Status Report for Buildings and Construction (Buildings-GSR) is a flagship publication of the UNEP-hosted Global Alliance for Buildings and Construction (GlobalABC). The Buildings-GSR provides an annual snapshot of the progress of the buildings and construction sector on a global scale and 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.

What is new in the 2022 Buildings-GSR? 

• Buildings and construction: disruptions and challenges facing the buildings sector in 2022 
• Global Building Carbon Tracker: Are we on track towards the Paris Agreement Goals?
• Updates on building codes and building decarbonisation in Nationally Determined Contributions (NDCs)
• Status of investment in building energy efficiency
• Deep dive on:
  • Africa (regional focus)
  • Building materials (topical focus)

The 2022 Buildings-GSR finds that 

• Despite a substantial increase in investment and success at a global level lowering the energy intensity of buildings, the sector’s total energy consumption and CO2 emissions increased in 2021 above pre-pandemic levels. Buildings energy demand increased by around 4% from 2020 to 135 EJ – the largest increase in the last 10 years. CO2 emissions from buildings operations have reached an all-time high of around 10 GtCO2, around a 5% increase from 2020 and 2% higher than the previous peak in 2019. 
• The buildings and construction sector is not on track to achieve decarbonization by 2050. And the gap between the actual climate performance of the sector and the decarbonization pathway is widening.
• Global energy price volatility and rising interest rates are likely to hamper investment in building decarbonization by governments, households, and businesses.

Effective energy efficiency policy is more important than ever for mitigating carbon emissions and improving energy access globally. Policymakers and researchers can take advantage of Mepsy, CLASP’s free policy analysis tool, to make data-driven decisions about managing the top energy-consuming appliances, now including lighting and considerations for varying compliance levels. This webinar, held on 16 March 2022, informed participants of two major additions to Mepsy’s toolkit: lighting and compliance. In addition, CLASP demonstrated how to use Mepsy to perform custom analyses and multiple tier policy analyses, in response to high demand for the feature.

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.

Les marchés de la climatisation ont connu au cours des dernières années une croissance soutenue qui a conduit à une progression constante des taux d’équipement. Pour les ménages, l’enquête réalisée à l’été 2020 a constaté un taux d’équipement de 25%. Dans le secteur tertiaire, toutes activités confondues, la proportion de surfaces climatisées est évaluée à 40 %, avec de fortes variations entre les différents secteurs.
Cet essor de la climatisation s’accompagne de la montée de la problématique de son impact environnemental. En effet, les équipements de climatisation agissent sur le climat au travers de leurs consommations énergétiques et via les émissions de GES des fluides frigorigènes chargés dans les équipements.
Les évolutions technologiques permettent d’envisager une amélioration du bilan environnemental des équipements et systèmes de climatisation. Mais la prise de conscience des utilisateurs, les conduisant à privilégier un usage raisonné des systèmes, constitue indéniablement une priorité pour les prochaines années. Augmenter la température d’ambiance dans un local climatisé, limiter l’usage de la climatisation aux périodes de fortes chaleurs et adopter les «bons gestes» conduisent immédiatement à des réductions très importantes des consommations énergétiques associées à ces systèmes.
