Policy strategies for achieving large long-term savings from retrofitting existing buildings

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 rapid review identified two results extracted from the eight studies (published between 2013 and 2018) that fulfilled our inclusion criteria. Firstly, our analysis identified five common themes across the included studies which provide tentative information for what would be needed to make low carbon residential retrofit/renovation policy work. Secondly, we make an overall observation that the included studies did not provide sufficient evidence or establish conclusive results about the effectiveness of specific low carbon policies compared to other policies.

Adopting Decarbonization Policies for the Building and Construction Sector: Costs and Benefits

Text
English
Authors:
Peter Graham

The building sector is not on track to lower total greenhouse gas emissions. Given that emissions from the sector represent nearly 40% of global energy-and process-related emissions, this represents a serious challenge to keeping global warming to 1.5oC. The Buildings sector must therefore decarbonize.To support this goal, this report focuses on policy drivers for decarbonisation, and the costs and benefits associated with their implementation.

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.

How to reduce household carbon emissions: A review of experience and policy design considerations

Text

Authors:
Xiaoling Zhang,

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.
