The renovation of buildings for greater energy efficiency is a challenging problem. Despite significant efforts, the renovation rate has remained stagnant for years. As a result, the search for alternatives has intensified. Using synthetic fuels to replace energy sources such as natural gas and heating oil have increasingly come under consideration, particularly when combined with greater integration between energy sectors. The hope is that using these fuels will allow buildings and boilers to be left as they currently stand.
But are these fuels truly alternatives to increased energy efficiency? If the sluggish pace of building renovation is allowed to continue, then lower efficiency rates must be balanced out with increases in renewable energy use and heat pumps, or more synthetic fuels. But these alternatives also incur additional costs and have yet to be thoroughly tested under real-world conditions.
In short, there is no easy way to get around the slow rate of building renovation. This study demonstrates that aggressive energy efficiency policies are crucial if buildings are to make any significant contribution to climate protection. Efficiency in buildings is essential for meeting climate protection goals in 2030 and beyond. It is also a significant factor in guaranteeing that a range of CO2-free residual heating technologies are competitive in the future.
