It is now established that energy use in buildings is a significant source of global greenhouse gas emissions and that abatement by the building sector can provide significant social, economic and environmental benefits. This paper examines the application of socio-technical transition theory to the building sector with Australian energy policy as a case study. The relatively high level of local building construction offers significant opportunities for market transition with appropriate policy settings so this national case has international implications.
Building energy efficiency is an important strategy for reducing greenhouse gas emissions globally. In fact, 55 countries have included building energy efficiency in their Nationally Determined Contributions (NDCs) under the Paris Agreement. This research uses building energy code implementation in six cities across different continents as case studies to assess what it may take for countries to implement the ambitions of their energy efficiency goals.
This paper introduces the major state-level regulations and policies for improving energy efficiency in buildings. The purpose of the review is to discuss the challenges and issues in policy implementation and the latest trend in adopting innovative instruments. The implementation of customer efficiency programs increasingly incorporates non-price instruments to encourage participation and deep savings. States pay attention to not only code adoption and update but also compliance and evaluation.
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 research combines two parallel and complementary work packages.The first examines the relationship between technical building energy performance improvements relating to electricity and gas end uses (e.g.
The contribution of buildings to climate change has become widely acknowledged. On 3 December 2015, the United Nations Environment Programme (UNEP) held the first ‘buildings day’ at COP 21 (the UN Climate Change Conference) devoted to the decarbonization of the building stock. There are several forms of negative contributions that buildings make to climate change, but high on the list are embodied and operational energy demands, which largely depend on fossil fuels and result in greenhouse gas emissions.
Under Article 7(1) of the Directive, France must make annual savings of 1.5 % of energy sales to end consumers compared to the average for 2010-12. To obtain the volume of energy sales, own generation of energy and the renewable share of renewable heat energy were subtracted from the non-climate corrected end energy consumption.
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.
This report presents the results of a state-by-state analysis of the potential energy and cost savings from improving compliance with building energy codes to 100 percent from current levels. The report also examines 45 statewide compliance evaluation studies, providing a summary of evaluation methods and key findings. Evidence in most states indicates that staggering rates of non-compliance, as high as 100 percent in some jurisdictions, have eroded the gains from energy code development and adoption.
The gap between actual carbon prices and those required to achieve ambitious climate change mitigation could be closed by enhancing the public acceptability of carbon pricing through appropriate use of the revenues raised. In this Perspective, we synthesize findings regarding the optimal use of carbon revenues from both traditional economic analyses and studies in behavioural and political science that are focused on public acceptability.
Focusing on the voluntary LEED and ENERGY STAR environmental certification schemes in the United States, we investigate whether price premiums exist across all building value categories or are localized to specific value segments. We find that the largest value building segment does not demonstrate any price premiums, while the smallest value categories do. The concentrated supply of eco-labeled offices in large, high-quality buildings likely contributes to this phenomenon.
