The U.S. Department of Energy (DOE) Building Energy Codes Program (BECP) periodically evaluates national and state-level impacts associated with energy codes in residential and commercial buildings. Pacific Northwest National Laboratory (PNNL), funded by DOE, conducted an assessment of the prospective impacts of national model building energy codes from 2010 through 2040. A previous PNNL study evaluated the impact of the Building Energy Codes Program; this study looked more broadly at overall code impacts.

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.

Developed as a common EU framework of core indicators for the sustainability of office and residential buildings, Level(s) provides a set of indicators and common metrics for measuring the environmental performance of buildings along their life cycle. As well as environmental performance, which is the main focus, it also enables other important related aspects of the performance of buildings to be assessed using indicators for health and comfort, life cycle cost and potential future risks to performance.

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.

The ABRACADABRA project is developing a toolkit, targeting policy makers, with a focus on regulatory challenges and opportunities for boosting energy retrofitting of buildings. For this purpose, the project will investigate regulatory issues, as well as available good practices, in the project’s target countries (Bulgaria, Greece, Italy, Latvia, Norway, Romania, Spain, and the Netherlands).

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.

Retrofitting has been proposed as a method to significantly reduce energy consumption and emission derived from the housing sector. Having said this it remains clear that severe restraints remain; and the concept of a “one solution fits all” is at the very least unrealistic. As it has been repeatedly supported via the Abracadabra project any potential solution must deal with significantly complex issues at technical, legislative and regulatory levels, and of course at financial and economic levels.

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).

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.

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

In a prior study entitled “Mapping of Existing Energy Efficiency Standards and Technologies in Buildings in the UNECE Region”, the UN Committee on Housing and Land Management (CHLM) and the Committee on Sustainable Energy (CSE) commissioned a comparative study on building standards in the UNECE region. The current report follows up on this by analyzing the actual prevalence of specific types of energy-efficient technologies in the buildings sector in the UNECE region, along with the levels and types of public policy interventions supporting their implementations.

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

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.

While governors across the United States are setting innovative energy policies, energy efficiency can help them go even farther toward meeting state goals. Saving energy creates jobs, develops the workforce, grows state economies, improves public health, promotes technological innovation, protects the environment, and saves taxpayers money. This toolkit lays out steps governors can take to increase energy efficiency in homes, businesses, and transportation.
