Around the world, engineers, architects and policymakers have been exploring ways to deliver highly efficient buildings whose reduced energy demand is satisfied by clean, renewable energy. Building off of the broader concept of a green or sustainable building, the concept of the “net zero building” focuses on the energy dynamics and performance of the building. And as policymakers and leaders align toward the net zero concept, the focus on achieving deep energy efficiency has centered on integrated technologies as well as ways to connect buildings to the natural environment.

This research combines two parallel and complementary work packages.The first examines the relationship between technical building energy performance improvements relating to electricity and gas end uses (e.g.

The contribution of buildings to climate change has become widely acknowledged. On 3 December 2015, the United Nations Environment Programme (UNEP) held the first ‘buildings day’ at COP 21 (the UN Climate Change Conference) devoted to the decarbonization of the building stock. There are several forms of negative contributions that buildings make to climate change, but high on the list are embodied and operational energy demands, which largely depend on fossil fuels and result in greenhouse gas emissions.

Under Article 7(1) of the Directive, France must make annual savings of 1.5 % of energy sales to end consumers compared to the average for 2010-12. To obtain the volume of energy sales, own generation of energy and the renewable share of renewable heat energy were subtracted from the non-climate corrected end energy consumption.

In-home displays, dynamic pricing, and automated devices aim to reduce residential electricity use—overall and during peak hours. We present a meta-analysis of 32 studies of the impacts of these interventions, conducted in the US or Canada. We find that methodological problems are common in the design of these studies, leading to artificially inflated results relative to what one would expect if the interventions were implemented in the general population.

Improving residential energy efficiency is widely recognised as one of the best strategies for reducing energy demand, combating climate change, and increasing security of energy supply. However, progress has been slow to date due to a number of market and behavioural barriers that have not been adequately addressed by energy efficiency policies and programmes. This study is based on updated findings of the European Futures for Energy Efficiency Project that responds to the EU Horizon 2020 Work Programme 2014–2015 theme ‘Secure, clean and efficient energy’.

The building sector is not on track to lower total greenhouse gas emissions. Given that emissions from the sector represent nearly 40% of global energy-and process-related emissions, this represents a serious challenge to keeping global warming to 1.5oC. The Buildings sector must therefore decarbonize.To support this goal, this report focuses on policy drivers for decarbonisation, and the costs and benefits associated with their implementation.

A JRC workshop on split incentives organised in the framework of article 19(1)(a) of the Energy Efficiency Directive (Directive) has been organised in order to examine current solutions addressing split incentives in the building sector in Europe and beyond. The workshop focused on the social housing, private residential and commercial sectors. Practices from Italy, the Netherlands, the UK, Denmark, Sweden and the US were presented and a panel discussion between representatives from groups of landlords, tenants, social housing and ESCOs was held.

Residential buildings use approximately 20 percent of the total U.S. energy consumption, and single-family homes alone account for about 16 percent. Older homes are less energy efficient than newer ones, and, although many experts have identified upgrades and improvements that can yield significant energy savings at relatively low costs, it has proven to be difficult to spur most homeowners into making these investments.

The gap between actual carbon prices and those required to achieve ambitious climate change mitigation could be closed by enhancing the public acceptability of carbon pricing through appropriate use of the revenues raised. In this Perspective, we synthesize findings regarding the optimal use of carbon revenues from both traditional economic analyses and studies in behavioural and political science that are focused on public acceptability.

Belt and Road Initiative (BRI) countries are major energy producers and consumers in the world, and they have enormous potential for energy cooperation, energy saving, and CO2 emissions reduction due to their various resource endowments. However, little quantitative research has been conducted under the BRI in the same framework.

This paper analyses the field of innovation studies regarding barriers to low-carbon innovation and consequences for finance (investment and divestment) and contributes to a more holistic understanding of the underlying mechanisms. A combination of technological barriers combined with economic barriers, institutional and political barriers contribute to suboptimal low-carbon investment all along the innovation cycle. Policy makers need to take a systemic approach to enable the redirection of diverse private financial sources.

Municipal policies can reduce greenhouse gas emissions and help to mitigate climate change. It is often unclear why cities would adopt such policies, however, given that the benefits from climate mitigation will be felt globally, rather than exclusively locally. Studies have identified a rationale for urban mitigation and energy policies rooted in local co-benefits, such as improvements in local environmental quality or job creation. Here we explore the possibility of financial co-benefits: whether municipal climate policies lead to an enhanced creditworthiness.

Contemporary societies are facing a broad range of challenges, from pressures on human health and well-being to natural capital depletion, and the security of food, water and energy. These challenges are deeply intertwined with global processes, such as climate change and with local events such as natural disasters. The EU's research & innovation (R&I) policy is now seeking to address these challenges from a new perspective, with Nature-Based Solutions, and turn them into innovation opportunities that optimise the synergies between nature, society and the economy.

With the urgency of climate change, and billions spent globally on renewable energy (RE) support policies, it is crucial to understand which policies are effective. Substantial scholarly research on RE deployment policies has been carried out over the last two decades, resulting in inconclusive findings regarding the effectiveness of mobilizing private finance. Here, we take a novel perspective and review 96 empirical studies concerning the impact of policies on two key investor decision metrics: investment risk and investment return.

The built environment accounts for approximately forty percent of the total energy consumption in developed countries. Because buildings have a long life, the greatest opportunity for energy reduction in the built environment will come from energy conservation in the existing building stock. An overview of the policy challenges presented by the built environment, with an emphasis on existing facilities, is accompanied by a discussion of specific technologies that may have the potential to reduce energy use.

Standards, subsidies, and carbon taxes are among the measures often considered to reduce energy consumption and carbon dioxide (CO₂) emissions in the buildings sector. Using a modeling system developed by the U.S. Energy Information Administration, residential and commercial sector standards and subsidies were each modeled with and without a carbon tax to determine if a multipolicy approach would be redundant. A separate case examining a carbon tax was also completed for comparison.
