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.

In summary: 

1. As a result of Colombia’s new green codes, buildings are expected to consume 10 to 45 percent less energy and water. These reductions will avoid nearly 190,000 metric tons of greenhouse-gas emissions by 2021, helping big cities like Bogota achieve a goal to reduce 2019’s greenhouse-gas emissions by 16 percent compared to 2007.2,3

To maximise the benefits from its application of BIM to infrastructure projects within its annual capital program, this framework will support the effective use of BIM across Queensland Government infrastructure delivery agencies. A focus of the framework includes BIM capability development across government and industry.

USGBC local communities around the country are helping cities jumpstart their building performance benchmarking efforts. And the results are pretty exciting. After four years of benchmarking in New York City, buildings there are using almost 15 percent less energy according to MIT professor David Hsu, one of the most widely recognized experts in energy benchmarking analysis.

Potential gains from improving energy efficiency are substantial — not only in terms of saving energy and combating climate change, but also in terms of contributing to an array of other co-benefits, including improving human health and creating jobs. We asked Tim Farrell, Senior Advisor at the Copenhagen Centre on Energy Efficiency, what works best when it comes to boosting energy efficiency. He stressed that targeted policy measures and sufficient resources to support implementation and compliance are among a number of critical ingredients for success.

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.

This article is part of our Urban Expeditions series, an initiative made possible by a grant from United Technologies to the National Geographic Society. As the world’s urban population expands, architects and planners are mapping out ways to make cities more sustainable. Cities produce a vast amount of emissions and waste, putting a strain on both human and ecological health. But our buildings themselves may hold a solution.

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.

Energy transition of the EU building stock, from being an energy waster to being highly energy efficient and an energy producer, is a prerequisite for Europe’s carbon neutrality, as well as for meeting Europe’s Sustainable Development Goals (SDGs). Achieving these targets requires shifting the emerging energy renovation market from a market of step-by-step and shallow energy renovation financed by grants to a market of industrialized and holistic energy renovation leading to zero energy buildings financed by long-term loans.

The earth is on a trajectory to warm 3-4°C by 2100. This heat map details how that rise in temperatures will affect major metropolitan hubs.

Smart Cities Dive took a closer look at how this would affect six major metropolitan hubs, and what the respective mayors and city leaders are doing to curb climate impacts as the clock ticks.

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:

New research finds that people are willing to pay more for energy efficient housing, making the case for a mandatory national rating system for existing homes. 

“Location, location, location” is a time-honoured mantra for pricing property, but research shows buyers and renters are also prepared to pay a premium for energy efficiency.

Light, reflective surfaces can have a dramatic impact in cooling the surrounding air – in cities, but in the countryside too. Whitewashed walls, arrays of photovoltaic cells, and stubble-filled fields can all provide local relief during the sweltering decades ahead. But policymakers beware. It doesn’t always work like that. There can be unintended consequences, both on temperature and other aspects of climate, like rainfall. Even local geoengineering needs to be handled with care.

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.
