Various policies targeting at building energy efficiency have been promulgated by the Chinese government in the past decade. However, few studies evaluate if China is on the right path to meet its energy goals through these policies by providing an assessment of their effect in reducing energy consumption in residential buildings or the feasibility of such policies to catalyze these reductions.

Australia’s current national emissions reduction target is to reduce emissions to 26-28 per cent below 2005 levels by 2030. As a signatory to the Paris Agreement, Australia has committed to the goal of reducing global emissions to net zero emissions and to five yearly reviews of the national target starting from 2020, with the requirement that new pledges be higher than the previous pledge and reflect the highest possible level of ambition.

Buildings can balance the grid through proactive energy demand management and can play a leading role in transforming the EU energy market, shifting from centralised, fossil-fuel-based systems towards a decentralised, renewable, interconnected and variable system. Many actors agree that buildings have a role in shaping the Energy Market Design Initiative.

In February 2015 the principle of ‘Efficiency First’  (E1st) was formally endorsed by the European Commission within the framework of the Energy Union.

This paper outlines and critically ‘maps’ existing roadmaps relevant to transitions to a low or zero carbon built environment in Australia. A roadmap describes the measures required to achieve goals and/or map future innovation opportunities. The three questions addressed by a comprehensive roadmap are: Where do we want to go?, Where are we now?, and How can we get there? The review identified 13 roadmaps/plans that have been produced by: peak industry bodies (Australian Institute of Refrigeration Air Conditioning and Heating); academic research groups (e.g.

This document contains the highlights from the high-level roundtable organised in the framework of the RenoValue project. The event took place at the European Parliament, in Brussels, Belgium, on 26 January 2016, providing the opportunity to discuss how policy makers can strengthen the role of property valuers as drivers of the market transition towards sustainable buildings.

For building owners, the renovation process can be a hassle, shaped by the ambiguity of the measures to implement. Uncertainty is one of the reasons why the renovation rate continues to linger around 1% and private investments remain limited. Achieving the full market potential of renovation calls for a paradigm shift, where a more service-oriented supply-side together with a deeper awareness on the demand-side play key roles. The BetterHome case study shows how innovative business models can drive energy renovations across Europe.

This report is an update from a similar document published in 2013. In 2018, evidence gathered by the International Energy Agency has identified six critical factors to guide policy makers in realising potential savings in both new and existing buildings through the modernisation of building energy codes.

The “Clean Energy for All Europeans” package confirms the pivotal role of the EU building stock in meeting EU 2030 climate and energy targets. In fact, the projected decarbonisation of the EU energy system is mainly based on the renovation of existing buildings and the increased penetration of renewable energies in heating, cooling and power generation.

This document is the companion to parts 1 and 2 of the guidance on how to use Level(s). In part 1 a general introduction to Level(s) is provided, together with in Part 2 an overview of the macro-objectives, performance indicators and the three Levels of performance assessment (Level(s) - Part 1 and 2). The three Levels are:

The current shift from fossil energy resources to “green” energy — renewable energy plus storage in smart grids, many with electric vehicles providing grid services — is now a global phenomenon (International Energy Agency 2016; International Renewable Energy Agency [IRENA] 2017b).

Cities are increasingly taking actions such as building code enforcement, urban planning, and public transit expansion to reduce emissions of carbon dioxide in their communities and municipal operations. However, many cities lack the quantitative information needed to estimate policy impacts and prioritize city actions in terms of carbon abatement potential and cost effectiveness. This report fills this research gap by providing methodologies to assess the carbon abatement potential of a variety of city actions.

The EU building sector needs to develop and deploy more innovative solutions in order to enhance the building stock’s energy efficiency and help meet energy and climate policy targets. The European Union is therefore supporting projects that address design and construction processes as well as new technologies, with funding from the Horizon 2020 programme. The results developed by these projects address key challenges at each stage of the value chain for new nearly zero-energy buildings, deep renovation of existing buildings, and energy-smart buildings.

In NSW more than 10% of households and small business premises have installed a solar photovoltaic (PV) system (commonly called solar panels). When these solar customers use the electricity generated by their solar panels rather than buying electricity from their retailer, they save money. When they don’t use all this electricity themselves, the excess amount is exported to the grid, and they may be paid a ‘solar feed-in tariff’ for this electricity.

The U.S. Green Building Council’s Leadership in Energy & Environmental Design (LEED®) green building certification has transformed how the building industry
and the public consider sustainability in the built environment. The most recent update to LEED, known as LEED v4, is the new standard for high-performance

Analysis of energy renovation costs, as provided by the French Observatory for Low Energy Buildings, identified the following:

This report is the Interim Technical Report for the Building Code Energy Performance Trajectory Project. It accompanies the Interim Synthesis Report for the Building Code Energy Performance Trajectory Project, entitled The Bottom Line – the household impacts of delaying improved energy requirements in the Building Code and which was published on the 8th of February 2018, providing more detail on the assumptions behind and the preliminary results from the underlying modelling work.

The report provides the following key items:

Most energy efficiency programs target only one fuel, usually electricity or natural gas. While they achieve savings, they sometimes miss opportunities by failing to address other fuels. Dual-fuel programs, on the other hand, have the potential to save more energy, reduce program costs, and improve customer satisfaction. Yet many utilities still do not offer them because they often require collaboration with other utilities or program administrators, making them more difficult to run.

In 2017, New York State Energy Research and Development Authority (NYSERDA) developed its 2016 Stretch Code Supplement to the 2016 New York State Energy Conservation Construction Code. Since 2017, NYSERDA has continued to develop the 2018 edition, as part of the efforts to achieve a statewide Net Zero Energy Code by 2028.
