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 article provides useful information that could help you address some barriers to sustainable initiatives: Every executive that you speak to is aware that data can be manipulated and may be skeptical of studies conducted by organizations that could benefit from a particular set of results. So I've included information on independent third-party studies. In challenging economic times, people are particularly concerned about short-term cash flow.

This paper reviews the empirical literature that provides a correlation between the different barriers to energy efficiency and consumer behavior related to two domains. It evaluates behavior related to energy curtailment, which represents routine, repetitive effort to decrease consumption on a day-to-day basis. It also considers behavior related to investments, which are one time actions such as purchasing new energy efficiency technologies. The paper also reviews the existing literature that assesses the effect of policies on energy use and investment in energy efficiency technologies.

This project, “International Review of Residential Building Energy Efficiency Rating Schemes”, is the fifth project in a series of work conducted through the Building Energy Efficiency Task Group (BEET), under the International Partnership for Energy Efficiency Cooperation (IPEEC). This project report presents key governance and administrative considerations in the design of energy efficiency rating schemes, available information on the cost-effectiveness and market impact of rating schemes, barriers to uptake of schemes and lessons learned from the implementation of schemes.

The Dutch Government stimulates the application of energy efficiency measures to reduce the energy requirements of buildings, which are responsible for about 20% of the Dutch CO2 emissions. For our assessment, we followed a qualitative approach, due to a lack of data. We reviewed the mix of policy instruments and used stakeholder surveys and interviews. We found that energy use is not very likely to decline fast enough to achieve the Dutch policy targets for 2020. For new buildings, the policy mix works well, but its contribution to the policy targets is limited.

Thanks to new insights on the impacts that dwellings have throughout their life cycles, there has been increased attention to retrofitting innovative energy systems (IES) in existing housing. This paper uses an explorative case study design to gain more knowledge about the governance aspects of this under-researched topic. The central research question is: Which factors influence the adoption of innovative energy systems in social housing sites during renovation projects? To answer this question, eight large-scale renovation projects in The Netherlands were investigated.

In-home displays, dynamic pricing, and automated devices aim to reduce residential electricity use—overall and during peak hours. We present a meta-analysis of 32 studies of the impacts of these interventions, conducted in the US or Canada. We find that methodological problems are common in the design of these studies, leading to artificially inflated results relative to what one would expect if the interventions were implemented in the general population.

The Energy Efficiency Financial Institutions Group (“EFFIG”) identifies the need to engage multiple stakeholder groups, scale-up the use of several financial instruments within a clear and enforced “carrot and stick” legislative framework. This report identifies a number of approaches and instruments that have proven to encourage investments and multiple market barriers that stand in the way of an energy efficient Europe.

This report sets out the positive and negative impacts of improvements in energy efficiency in buildings that could come about through a recast of the Energy Performance Buildings Directive (EPBD). Successive studies have shown that energy efficiency offers many of the most cost-effective options for meeting global emission targets. In many cases, energy efficiency measures have been shown to be ‘negative cost’, meaning that it would be economically advantageous to implement them.

Owing to the rapid urban growth of past decades, the refurbishment of buildings has become a central topic of city development. A key aspect of building renovations deals with energy saving, both for economic and environmental concerns. The present literature mainly focuses on technological solutions for buildings, and the related data are studied with descriptive statistics. Instead, this paper aims to evaluate the energy effectiveness of refurbishment interventions from a global sector viewpoint.

The National Energy Productivity Plan (NEPP) is a package of measures to improve Australia’s energy productivity by 40% between 2015 and 2030. The NEPP is delivered jointly between the Australian Government and the state and territory governments. Energy Ministers recognised that improving energy productivity helps: businesses reduce their energy costs through innovation and modernising their infrastructure; households benefit through lower energy bills and increased home comfort; Australia reduce its greenhouse emissions.

Pricing carbon and moving toward mandatory disclosure of climate-related financial risks, as part of a broader policy package. Accelerating investment in sustainable infrastructure, supported by clear national and sub-national strategies and programmes. Harnessing the power of the private sector, including to unleash innovation and advance supply chain transparency. Ensuring a people-centred approach, such that the gains are shared equitably and the transition is just.

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.

Proposed changes flowing from the former Council of Australian Government’s Trajectory for Low Energy Buildings project1 (the trajectory) are expected to reduce annual electricity consumption of new and refurbished residential and commercial premises by 36 TWh by 2050, compared to current standards.

While energy efficiency can contribute significantly towards improving access to modern energy services, energy sector investments in many developing countries have largely focused on increasing energy access by increasing supply. This is because the links between energy efficiency and energy access, is often overlooked. This oversight of energy efficiency is frequently a missed opportunity, as efficiency is often a very cost-effective energy resource.
