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.

The review of policies being implemented in China, the EU, India and the US presented in this report has also identified some key challenges that we must address if we are going to realize the mitigation potential of the building sector. Chief among these is the need to improve our monitoring of the impact that our policies are having. Lack of measured and verifiable data on the influence of policies on building energy performance currently hampers our ability to assess and continuously improve their effectiveness.

This paper outlines the approach and the cost-effectiveness potential for designing and retrofitting residential buildings to be energy-efficient in Bahrain. The analysis is focused on residential buildings since these buildings consume over 48% of the total electricity used in Bahrain. The optimization analysis has the benefit to assess both at the individual building and the national building stock levels, the potential of the application of currently proven measures and technologies to improve the energy efficiency of the building sector in Bahrain.

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.

This study compares and contrasts Australian and global best practices in policy and regulation for the energy and carbon performance of the built environment. It examines the drivers and opportunities for, and barriers to, the adoption of best practices in Australia. Finally, and as a stimulus to debate, it proposes a potential set of optimal measures, at national, state/territory and local levels, along with an indicative pathway for their implementation.

Energy efficiency policies have the unique capacity to contribute to a more sustainable energy future at an economic net benefit even when co-benefits are not included in the evaluations. The purpose of this paper is to present quantitative and comparative information on the societal cost-effectiveness and the lifetime energy savings of all light eight building energy efficiency policy instruments.

The UN Sustainable Energy for All initiative aims to double the global rate of improvement in energy efficiency by 2030.i Efficient buildings are vital to achieving sustainable development because they align economic, social, and environmental objectives, creating triple bottom line benefits. However, the scale and pace of current actions around the world are insufficient to transform buildings into engines of the sustainable, energy efficient economy. This second-edition report reviews government policy options that can accelerate building energy efficiency improvements.

The Dutch Government stimulates the application of energy efficiency measures to reduce the energy requirements of buildings, which are responsible for about 20% of the Dutch CO2 emissions. For our assessment, we followed a qualitative approach, due to a lack of data. We reviewed the mix of policy instruments and used stakeholder surveys and interviews. We found that energy use is not very likely to decline fast enough to achieve the Dutch policy targets for 2020. For new buildings, the policy mix works well, but its contribution to the policy targets is limited.

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.

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.

Owing to the rapid urban growth of past decades, the refurbishment of buildings has become a central topic of city development. A key aspect of building renovations deals with energy saving, both for economic and environmental concerns. The present literature mainly focuses on technological solutions for buildings, and the related data are studied with descriptive statistics. Instead, this paper aims to evaluate the energy effectiveness of refurbishment interventions from a global sector viewpoint.

Nowadays, energy efficiency (EE) is presented as a reliable strategy towards sustainable development, but its application has not been developed equitably worldwide, since most EE policies have been implemented in industrialised nations, and developing countries are still in the process of improving their EE levels.

This Annual Report covers the second in a 15-year plan and shows that the NEPP has continued to progress well. Throughout 2017, measures across the work plan have advanced and many have achieved significant outcomes. There has also been wider progress in energy policy and jurisdictional measures which will contribute strongly to energy productivity and NEPP objectives. This document highlights key outcomes, their expected impacts and links to broader reforms.

The National Energy Productivity Plan (NEPP) is a package of measures to improve Australia’s energy productivity by 40% between 2015 and 2030. The NEPP is delivered jointly between the Australian Government and the state and territory governments. Energy Ministers recognised that improving energy productivity helps: businesses reduce their energy costs through innovation and modernising their infrastructure; households benefit through lower energy bills and increased home comfort; Australia reduce its greenhouse emissions.

Green building councils, and the rating tools they operate, exist largely to provide clear market signals to consumers, industry and the government on green building claims. The relationship between green building councils, the rating tools, and the market is built on trust with the market depending that the information provided by green building councils, and their rating tools, is accurate and unbiased.

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.
