The energy system is a vital infrastructure which can be vulnerable to climate variability and change (CV&C) impacts. Understanding the impacts can prevent disruption and inform policy decision making. This study applied a scoping review in a systematic manner following the Joanna Briggs Institute guidelines to identify consistent patterns of CV&C impacts on the energy system, map and locate research gaps in the literature. A total of 176 studies were identified as eligible for inclusion in the review.

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 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.

The EU and Australia have instituted significant new public policies to promote energy efficiency in the “built environment.” Many of these public policies were motivated by the same concerns that led to the pioneering voluntary initiatives of Green Building Councils (especially the LEED design certification program) and the U.S. Department of Energy’s ENERGY STAR system for buildings. However, policy initiatives on both continents are relatively new, have been recently modified, and are yet to be finalized.

Due to the growing concerns about global climate change and energy dependence, many countries have introduced regulations targeting the energy efficiency of the residential sector. However, whether these policies have been effective in reducing the total residential consumption of energy is still unclear. In this paper, we analyze the impact of residential energy efficiency policies on household energy consumption across Europe for the period 1980–2016.

Building energy code change in Australia, and many other developed nations, is subject to standardised economic tests, with a net present value calculation at the heart of the economic analysis. Although many nations have introduced minimum energy efficiency standards for residential and commercial buildings, increases in stringency have been hindered by limitations to the range of private and societal impacts typically incorporated in regulatory impact assessments.

Buildings are the largest energy consuming sector in the world. Accounting for over one-third of total final energy consumption, they are an equally important source of carbon dioxide (CO2) emissions. Achieving significant energy and emissions reduction in the buildings sector is a challenging but achievable policy goal. Transition to Sustainable Buildings presents detailed scenarios and strategies to 2050 and demonstrates how to reach deep energy and emissions reduction through a combination of best available technologies and intelligent public policy.

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.

Climate change and global warming as the main human societies’ threats are fundamentally associated with energy consumption and GHG emissions. The residential sector, representing 27% and 17% of global energy consumption and CO2 emissions, respectively, has a considerable role to mitigate global climate change. Ten countries, including China, the US, India, Russia, Japan, Germany, South Korea, Canada, Iran, and the UK, account for two-thirds of global CO2 emissions.

Decarbonisation Futures provides a guide for Australian government and business decision makers on priority technologies, deployment pathways and benchmarks for achieving net zero emissions. Decarbonisation Futures shows Australia can still play its part in meeting the Paris Climate Agreement goal of limiting global temperature rise to well below 2 degrees Celsius and as close as possible to 1.5 degrees. This report identifies the priority technologies and actions for achieving net zero emissions across all sectors of the Australian economy.

We evaluate the effect of a change in the energy code applied to buildings using residential billing data on electricity and natural gas, combined with data on observable characteristics of each residence. The study is based on comparisons between residences constructed just before and after an increase in the stringency of Florida's energy code in 2002. We find that the code change is associated with a decrease in the consumption of electricity by 4% and natural gas by 6%. We estimate average social and private payback periods that range between 3.5 and 6.4 years.

This paper contrasts two perspectives on energy efficient home renovations from applied behavioural research on energy efficiency and from sociological research on homes and domestic life. Applied behavioural research characterises drivers and barriers to cost-effective renovations, and identifies personal and contextual influences on homeowners’ renovation decisions. Research findings inform policies to promote energy efficiency by removing barriers or strengthening decision influences.

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 report is the first report of the ‘Energy Savings 2030’-project which seeks to help the Coalition for Energy Savings to produce a robust and timely input to the 2030 policy discussion. It brings together and summarises recent empirical evidence on costs and benefits of energy efficiency measures. The evidence gap in terms of reliable ex-post data is well known. In the majority of cases results from ex-ante modelling studies inform the debate. The research carried out for this report confirms the persistent gap in publicly available ex-post evaluations of energy efficiency programmes.

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.

Globally, building energy regulation has been an effective policy instrument for reducing energy use and carbon emissions. In Australia, the majority of regions address building performance through the National Construction Code. However, in 2004 the New South Wales government introduced a planning instrument called the ‘Building Sustainability Index’, known as BASIX. Until now there has been limited investigation of this sustainability index approach compared with addressing issues individually through building standards.

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.

A practical decision support pack to aid policy makers and experts in developing countries. The objective of the Sustainable Building Policies in Developing Countries (SPoD) project is to enable authorities at national and local levels to analyse existing policies affecting the building sector, and to identify packages of policy instruments for sustainable buildings, which can be adapted to fit local conditions.

The European construction industry, like many others, is confronted by an economy that isundergoing a highly significant change, shaped by megatrends such as greater urbanisation,disruptive new technologies and digitalisation, globalised value chains and sustainability.At the same time, the European economy faces the profound challenge of meeting theambitious climate mitigation goal set out in the Paris Agreement of keeping average globalwarming to well below 2˚C.
