Mainstreaming high-performance buildings could deliver a 124% return on investment globally through building-related energy cost savings by 2050 says a new comprehensive assessment study of the costs and benefits of low energy building pathways published by the GBPN.

Mainstreaming high-performance buildings could deliver a 124% return on investment globally through building-related energy cost savings by 2050 says a new comprehensive assessment study of the costs and benefits of low energy building pathways published by the GBPN in cooperation with the Central European University’s Center for Climate Change and Sustainable Energy Policy (3CSEP) and Advanced Building and Urban Design (ABUD).
First adopted in 2007, and most recently renewed in 2015, New Mexico’s Sustainable Building Tax Credit supports the greening of many building types across the state. Released in October, 2017, this case study captures the impacts of this landmark policy and highlights the context and people that helped to create and sustain this nation-leading green building policy.
This is an example of LEED being used in an innovative tax policy across the United States and potentially serve as a tax model elsewhere.
Buildings are the focus of European (EU) policies aimed at a sustainable and competitive low-carbon economy by 2020. Reducing energy consumption of existing buildings and achieving nearly zero energy buildings (NZEBs) are the core of the Energy Efficiency Directive (EED) and the recast of the Energy Performance of Building Directive (EPBD). To comply with these requirements, Member States have to adopt actions to exploit energy savings from the building sector.
In order to achieve long-term targets for energy savings and emission reductions, substantial savings will be needed from existing buildings. For example, a recent analysis for the USA examines aggressive strategies to cut carbon emissions in half by 2040 and finds that in order to achieve this emission reduction target, more than half of existing buildings will need comprehensive energy efficiency retrofits. Germany is targeting an overall primary energy consumption reduction of 50% in 2050 including increasing building renovation rate to 2% per year.
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.
Global warming and environment problems caused by the excessive emission of greenhouse gases (GHGs), along with rapid economic development has attracted the attention of many countries and regions of the world. Reducing GHG emissions is essential to mitigate the threat of global warming. Household carbon (dioxide) emissions have been recognized as one of the most important contributors to climate change, with a significant impact on both the local and global environment, and various policy instruments have been implemented by governments to bring about the reduction.
Nearly zero energy buildings (NZEBs) constitute one of the main pillars of the energy policy of European Union (EU). Greece has recently established a clear definition for NZEB, however the interdependence between cost-optimality and the energy performance of NZEB has not been adequately studied. The present work includes a cost effectiveness analysis among different energy efficiency interventions for the existing residential Greek building stock.
Sustainable development in the building sector requires the integration of energy efficiency and renewable energy utilization in buildings. In recent years, the concept of net zero energy buildings (NZEBs) has become a potential plausible solution to improve efficiency and reduce energy consumption in buildings. To achieve an NZEB goal, building systems and design strategies must be integrated and optimized based on local climatic conditions. This paper provides a comprehensive review of NZEBs and their current development in hot and humid regions.
