Concerns about climate change, energy security and energy productivity are driving countries to improve energy and thermal efficiency of their housing. Australia established a Nationwide House Energy Rating Scheme (NatHERS) in the mid-1990s to encourage improved energy performance, before regulating minimum energy standards in the 2000s. While minimum standards in Australia have improved, they fall short of requirements for a low carbon future. Resistance to new standards has been predicated on the argument that consumers will drive the market.

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.

Cities in developing countries seldom consider the cost increases that regulations impose on development. To build legal housing, developers must meet a high minimum cost threshold established by mandatory standards. Many standards impose costs on building construction, make them less affordable to low-income households, deprive them access to legally built housing, and fuel the formation of slums.

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.

In 2009, the European Union adopted high-level goals for renewable energy, energy efficiency, and greenhouse gas reductions with targets set toward the year 2020. This was followed in 2012 by adoption of the Energy Efficiency Directive (EED) (2012/27/EU), which included as a major component a requirement for Member States to create Energy Efficiency Obligations Schemes (EEOSs) on energy companies or equivalent alternative measures, and those provisions have now been in effect for three years.

Globally, building energy regulation has been an effective policy instrument for reducing energy use and carbon emissions. In Australia, the majority of regions address building performance through the National Construction Code. However, in 2004 the New South Wales government introduced a planning instrument called the ‘Building Sustainability Index’, known as BASIX. Until now there has been limited investigation of this sustainability index approach compared with addressing issues individually through building standards.

A majority of carbon dioxide is emitted from cities. However, due to the complexity of urban energy consumption behaviour and lack of sufficient data, the influencing mechanisms of urban energy efficiency has not been fully understood. This paper presents a systematic study to identify the key energy efficiency drivers related with major urban performance aspects, such as R&D, livability, etc. First, the performance indicators of 25 global cities are collected from the Global Power City Index (GPCI) report and other data sources.

The main aim of this report is to contribute to the exchange of good practices and to support EU MS by providing potential ideas for the elaboration of long-term renovation plans. The report compiles renovation requirements as well as financial instruments, support programmes and market mechanisms for building renovation in a number of countries and regions. While the main focus of the report is on selected EU MS, a few global examples are also presented.

Standards, subsidies, and carbon taxes are among the measures often considered to reduce energy consumption and carbon dioxide (CO₂) emissions in the buildings sector. Using a modeling system developed by the U.S. Energy Information Administration, residential and commercial sector standards and subsidies were each modeled with and without a carbon tax to determine if a multipolicy approach would be redundant. A separate case examining a carbon tax was also completed for comparison.

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.

The Clean Energy Finance Corporation (CEFC) commissioned Energy in Buildings: 50 Best Practice Initiatives as a practical, user-friendly resource for property owners and managers, hoping that this will lead to greater awareness and implementation of initiatives across the property industry to reduce costs and emissions.

While many researchers have analyzed the obstacles to the diffusion of innovation in building construction, little empirical evidence has been gathered about the factors associated with U.S. homebuilders’ adoption of innovative building products. In this paper, we develop a theory driven diffusion of innovation conceptual model of homebuilders’ adoption of high performance building product innovations. We are among the first to operationalize a regression model to demonstrate an application of the model using a large dataset from the National Association of Homebuilders.

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.

This chapter examines the experience of construction unions and community organizations as they enter into strategic alliances to create new markets in energy efficient systems. I focus on two recent policy initiatives: PlaNYC for the retrofitting of public and commercial properties in New York City, and Green Jobs/Green New York (GJ/GNY) for the retrofitting of non-commercial residential properties in the rest of the city and the state.
