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 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.

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 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.

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.

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.

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.

This paper on the zero carbon and circular challenge in the built environment puts forward several policy recommendations. In order to achieve the net-zero carbon goal by 2050, adapting the built environment is paramount: the EU estimates that the climate change-related damage to infrastructure could grow tenfold under a business-as-usual scenario. The paper advocates the need to come up with a comprehensive strategy for the building and construction sector which should build on the principles of sustainability and circularity.
