Energy policy continues not to acknowledge the gap between the calculated (i.e. the anticipated or promised) and the actual consumption associated with peoples’ everyday practices in their homes and in the building sector. Multiple explanations exist for why this ‘performance gap’ occurs.

Urban density significantly impacts urban energy use and the quality of life of urban residents. Here, the authors provide a global-scale analysis of future urban densities and associated energy use in the built environment under different urbanization scenarios. The relative importance of urban density and energy-efficient technologies varies geographically. In developing regions, urban density tends to be the more critical factor in building energy use.

Abstract

The reduction of the energy consumption and carbon emissions in the building sector is an important target for actions to mitigate the climate changes and different actions are being carried out to promote a transition to a low carbon built environment. However, present standards are mainly focused on new buildings which may result counter-productive in existing ones, due to their technical, functional and economic constraints.

Nigerian government has begun to develop plans that will address green buildings and environmental sustainability, a matter and issue on which Malaysia has wide-ranging experiences. Through a comparative study on green building policies in Malaysia and Nigeria, the study identified important lessons relevant to Nigeria green building policies and programmes and creates a general explanation of Malaysia green building policies that could be applicable to Nigeria.

Australian residential sector contributes approximately 13 per cent of the total greenhouse gas (GHG) emissions. The New South Wales (NSW) government in Australia has introduced mandatory energy efficiency/ GHG emissions reduction target through the Building Sustainability Index (BASIX) assessment tool, which estimates the operational energy consumption and GHG emissions from new residential developments based on information available at the building design stage.

The rationale for energy efficiency policy can be framed in terms of a variety of different benefits. This paper considers how different benefits have been used within the overall rationale for energy efficient retrofit policy in different contexts. We posit that different rationales may be used for the same policy response, and that the form of rationale used may affect the design, delivery or the level of policy support, with different rationales making it easier to account for different results.

This study describes the results of Life Cycle Assessment (LCA) applied to 24 statistically-based dwelling archetypes, representative of the EU housing stock in 2010. The aim is to quantify the average environmental impacts related to housing in Europe and to define reference values (baseline scenario) for policies development.

Building energy codes have been widely implemented in the world to regulate energy consumption and CO2 emissions from the building sector. In order to assess the impacts of building energy codes on Australian building performance, this paper has compared the energy efficiency requirements of the Building Code of Australia (BCA) with the USA ASHRAE Standard 90.1 and Chinese GB50189, in terms of the building envelope, HVAC chiller efficiency, internal load density, and HVAC temperature set-points.

The main problem in creating successful efficiency improvement policies is adjusting objectives to local development programs, dependent on public awareness. This article attempts to find a framework for the costs of changing energy policies using neural networks to identify the social-infrastructure conditions. An analysis model is presented of social-infrastructure conditions of energy costs reduction and buildings’ efficiency improvement.

India has demonstrated that it is possible to reduce energy demand and increase the energy efficiency of its buildings, particularly for air-conditioning appliances. Given the rapid and large expected increase in India's building stock over the next 20 or more years, the opportunity exists to make significant increases in overall energy efficiency and reduce energy demand through the application of its Energy Conservation Building Code that influences the design, construction and operation of buildings.

This paper applies cost–benefits analysis (CBA) and transaction cost (TC) theory to systematically evaluate the costs and benefits of implementing the green building economic incentives, with focused study on the Gross Floor Area (GFA) Concession Scheme in Hong Kong. The data of costs and benefits indicate how the GFA Concession Scheme motivates stakeholders and how much it benefits the built environment, which provides a solid foundation for the improvement of the GFA Concession Scheme.

India’s growth of energy demand in the building stock, and efforts to curb it, are placed into an international context by adapting the reporting criteria developed for the Global Alliance on Building & Construction's (GABC) Global Status Report (2017) on buildings and construction.

It is increasingly recognised that the risks associated with climate change must be addressed through both mitigation and adaptation. Buildings are vulnerable to climate change risk and are also the source of a significant proportion of greenhouse gas emissions which contribute to climate change.

Environmental issues, costs, and limited energy supply, among other concerns have been driving the efforts toward more energy efficient buildings over the last four decades. Hence, energy efficiency is not only well-established within the building design and construction industries, but is also an active field of research. Many countries have state-mandated building energy codes that are becoming more stringent with time. Therefore, the building stock in many regions is becoming more efficient.

Smart city experiments have the potential to reshape urban climate change governance. Smart city initiatives have been supported by international technology companies and the European Union for many years and continue to be promoted by national and municipal governments. In relation to sustainability and climate change, such initiatives promise more efficient use of resources through the use of information and communications technology in energy infrastructure.

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.

Limited literature exists on how insurance companies incorporate a focus on environmental sustainability into their core business strategy and practices. The article is intended to contribute to the implementation of corporate sustainability practices by presenting a framework or blueprint for insurance companies to follow which will enable them to integrate sustainability goals into their culture, core business, strategy and structure.

The article deals with efforts to reduce energy as a means to support the formulation of climate change public policies and strategies. Energy use in building design and operation is integral to these efforts. Energy efficiency advocates suggest that new buildings can (and should) be net-zero energy, and retrofitting existing buildings can achieve savings of approximately 50% (Architecture 2030, 2014).
