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 Whitepaper: The neglected demand side of the green equation, published by Danfoss during COP27, highlights:

  • Without urgent action, energy demand will grow significantly, getting us off track to meet global climate goals. Instead, according to IEA a collective push for energy efficiency can deliver one-third of the total emissions reductions needed to reach net zero.
  • Cooling is a global blind spot in climate change mitigation. As economies grow and adapt to a warmer climate, especially in the Global South, demand for cooling will make the second-largest contribution to the overall rise in global electricity demand over the coming decades.
  • Energy efficiency is an enabler of electrification. To grow the role of electricity in the energy mix it is a fundamental, yet overlooked, fact that we need to reduce energy demand first. An early analysis found that for every dollar spent on energy efficiency, we can avoid spending more than 2 dollars on energy supply.
  • Most of the global reductions in carbon emissions through 2030 needed for net zero come from technologies readily available today. This paper presents concrete policy measures to increase energy efficiency across sectors.

Global challenges are pushing cities to their breaking point. With cities expected to house 68 per cent of the world’s population by 2050, warming twice as fast as the global average, and disproportionately affected by extreme weather, we need to use every tool at our disposal to ensure a low-carbon, livable, resilient, and equitable urban future. One frequently overlooked tool with great potential is urban nature — cities’ forests, parks, street trees, green stormwater infrastructure, and bodies of water.

Building operations in India account for about a third of its energy use. Approximately another 10 percent of the country’s energy is used in the production of building material and construction of new buildings. In the absence of peremptory energy-efficiency improvements and policy measures, the buildings sector is estimated to consume over three times more energy by 2050 than what is consumed today. Notably, there is no energy transformation without a buildings sector transformation.

This report equips policymakers, building material manufacturers, building developers, end-users, and NGOs with technologies, policies, and market initiatives that can drive forward transformative solutions for the buildings sector. The solutions highlighted here are a result of decades of global research and collaboration with interdisciplinary thought leaders.

The State of Climate Action 2022 provides a comprehensive assessment of the global gap in climate action across the world’s highest-emitting systems (power, buildings, industry, transport, forests and land, food and agriculture, technological carbon removal, and finance), highlighting where recent progress made in reducing GHG emissions, scaling up carbon removal, and increasing climate finance must accelerate over the next decade to keep the Paris Agreement’s goal to limit warming to 1.5°C within reach.

Africa Climate Week 2022 was held 29 August to 2 September in Gabon. ACW 2022 engages and empowers stakeholders to drive climate action across countries, communities and economies. Turning Libreville, Gabon, into Africa's climate capitol for a week, ACW 2022 brought together more than 2,300 stakeholders for five days of discussion in more than 200 sessions, with many more joining through virtual participation. An ACW 2022 Output Report provides a record of engagement that can guide implementation of the Paris Agreement in Africa.

Here is the output on the Session 6 of the Track 1 (Striving for 1.5 Degrees) – Sustainable Buildings for Climate-Proof Cities

To meet the SDGs and Paris Agreement Goals, we need to accelerate decarbonization and transformation of the built environment with a whole life-cycle approach that addresses embodied and operational carbon.

  • Sustainable building materials and construction practices offer a key opportunity to move to circular, low-carbon, renewable materials and construction methods
  • Need effective strategies and policies that drive concrete actions and the uptake of sustainable building materials globally, especially in Africa
  • Policies and strategies are critical, designers and architects also play an important role to make sustainable building materials affordable and also desirable
  • Building and construction sector value chain is highly fragmented. To achieve global transformation of built environment, radical stakeholder collaboration by all is needed

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.

The Tracking Report on Buildings published by the International Energy Agency in September 2022 indicates that the buildings sector is "not on track"

In 2021 the operation of buildings accounted for 30% of global final energy consumption and 27% of total energy sector emissions (8% being direct emissions in buildings and 19% indirect emissions from the production of electricity and heat used in buildings). Both energy consumption and emissions rebounded to above 2019 values, following the drop in 2020 from Covid-19 restrictions.

Minimum performance standards and building energy codes are increasing in both scope and stringency, and the use of more efficient and renewable energy technology in buildings is accelerating while the power sector continues to decarbonise. Yet, the buildings sector needs more rapid change to get on track with the Net Zero Emissions by 2050 Scenario. This next decade is crucial to implement the necessary measures, in particular for all new buildings and 20% of the existing building stock to be zero-carbon-ready as soon as 2030.

We’ve reached the point where the real estate industry knows it needs to decarbonize and is ready to act. The climate risks – both physical and transition – are higher than ever. Stakeholder demand from investors and occupants continues to rise. More and more governments are passing regulations around reporting and performance across the globe. No longer is it too expensive for real estate to act on climate change: now, the price of inaction is too high. Real estate cannot afford a portfolio of stranded assets that are unable to meet increasingly high public, private, and consumer expectations for carbon and energy. Climate mitigation is material to real estate operations; real estate has a fiduciary responsibility to decarbonize. State of Green: Greenprint Performance Report, Volume 13 presents the data and analytics behind ULI Greenprint’s decarbonization progress.

In 2021, the collective Greenprint community – covering 74 companies and 15,000 properties in 31 countries – reported:

  • Carbon emissions: 4.4% reduction
  • Energy use: 0.0% reduction
  • Water use: 17.8% reduction
  • Waste diversion: 9.2% reduction

Commercial buildings generate about 16 percent of energy-related CO2 emissions in the United States and about half of the total emissions from the building sector. Furthermore, direct fossil fuel combustion in commercial buildings alone accounts for 5 percent of total energy-related CO2 emissions in the country.

Given that most commercial properties are large — over 80 percent of commercial floor space in the United States is in buildings larger than 10,000 square feet — and are more likely to be owned as part of a portfolio, there is an enormous opportunity to replicate and scale solutions for commercial electrification and ultimately to have an outsized impact in the building sector’s transition toward a clean, carbon-free future.

This report analyzes the technical, economic, and environmental implications of retrofitting fossil-gas-fired space heating and domestic hot water systems in a prototypical 50,000 square foot office building. We compared a range of system decarbonization scenarios to a conventional gas-fired system replacement including heat pump water heaters, heat pump rooftop units, energy recovery ventilation, peak heating demand management, and on-site solar photovoltaics.
