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.

It is clear that city must be part of the solution if an urbanizing world is to grapple successfully with ecological challenges such as energy depletion and climate change. A system dynamics model was developed in this study using STELLA platform to model the energy consumption and CO2 emission trends for the City of Beijing over 2005–2030. Results show that the total energy demand in Beijing is predicted to reach 114.30 million tonnes coal equivalent (Mtce) by 2030, while that value in 2005 is 55.99 Mtce, which is 1.04 times higher than the level in 2005.

This paper reviews the empirical literature that provides a correlation between the different barriers to energy efficiency and consumer behavior related to two domains. It evaluates behavior related to energy curtailment, which represents routine, repetitive effort to decrease consumption on a day-to-day basis. It also considers behavior related to investments, which are one time actions such as purchasing new energy efficiency technologies. The paper also reviews the existing literature that assesses the effect of policies on energy use and investment in energy efficiency technologies.

This project, “International Review of Residential Building Energy Efficiency Rating Schemes”, is the fifth project in a series of work conducted through the Building Energy Efficiency Task Group (BEET), under the International Partnership for Energy Efficiency Cooperation (IPEEC). This project report presents key governance and administrative considerations in the design of energy efficiency rating schemes, available information on the cost-effectiveness and market impact of rating schemes, barriers to uptake of schemes and lessons learned from the implementation of schemes.

The main aim of this report is to contribute to the exchange of good practices and to support EU MS by providing potential ideas for the elaboration of long-term renovation plans. The report compiles renovation requirements as well as financial instruments, support programmes and market mechanisms for building renovation in a number of countries and regions. While the main focus of the report is on selected EU MS, a few global examples are also presented.

A Global Survey of Building Energy Efficiency Policies in Cities is a resource for city officials around the world as they design new policies for building energy efficiency, or review existing ones. The research should help close the evidence gap regarding city-level activity in building energy efficiency. As such, it is designed to be accessible to those working in the field in general, including researchers.

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’.

In 2009, the European Union adopted high-level goals for renewable energy, energy efficiency, and greenhouse gas reductions with targets set toward the year 2020. This was followed in 2012 by adoption of the Energy Efficiency Directive (EED) (2012/27/EU), which included as a major component a requirement for Member States to create Energy Efficiency Obligations Schemes (EEOSs) on energy companies or equivalent alternative measures, and those provisions have now been in effect for three years.

The building sector is considered as the biggest single contributor to world energy consumption and greenhouse gas emissions. Therefore, a good understanding of the nature and structure of energy use in buildings is crucial for establishing the adequate future energy and climate change policies. Availability of the updated data is becoming increasingly important in order to allow a rigorous analysis. In this paper, recent data on the world energy consumption in both residential and commercial buildings are reported.

Global warming and environment problems caused by the excessive emission of greenhouse gases (GHGs), along with rapid economic development has attracted the attention of many countries and regions of the world. Reducing GHG emissions is essential to mitigate the threat of global warming. Household carbon (dioxide) emissions have been recognized as one of the most important contributors to climate change, with a significant impact on both the local and global environment, and various policy instruments have been implemented by governments to bring about the reduction.

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.

Following the 1960s environmental movement and the energy crisis in the 70s, evidence spurred research on renewable energy and energy efficiency practices. As a result, the green building (GB) movement emerged in the 90s to promote buildings which are designed to reduce the consumption of energy, electricity, water, materials, natural resources as well as improve environmental performance and human health over the whole lifecycle. With a prime goal of improving energy efficiency, GB has gained recognition in national and international energy policies.

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.
